Health Policy

SARS CoV-2 (severe acute respiratory syndrome corona-
virus 2) has challenged us all and will continue to do so for at least the next several months. This novel virus has uncovered our medical hubris and our collective failure to acknowledge our vulnerability in the face of biological threats. As government, public health, health systems, medical professionals, and individuals struggle to grasp its enormous impact, we must recognize and seize the opportunities for leadership that the coronavirus disease (COVID-19) pandemic presents to us as physicians.

For too long we have abdicated responsibility for driving change in the US health system to politicians, administrators, and those not on the front line of care delivery. We can, however, reclaim our voice and position of influence in 2 primary spheres: first, as ObGyns we have the specific clinical knowledge and experience required to help guide our institutions in the care of our patients under new and ever-changing circumstances; second, beyond our clinical role as ObGyns, we are servant leaders to whom the public, the government, our trainees, and our clinical teams turn for guidance.

Foundations for policy development

Disaster planning in hospitals and public health systems rarely includes consideration for pregnant and delivering patients. As ObGyns, we must create policies and procedures using the best available evidence—which is slim—and, in the absence of evidence, use our clinical and scientific expertise both to optimize patient care and to minimize risk to the health care team.

At this point in time there is much we do not know, such as whether viral particles in blood are contagious, amniotic fluid contains infectious droplets, or newborns are in danger if they room-in with an infected mother. What we do know is that the evidence will evolve and that our policies and procedures must be fluid and allow for rapid change. Here are some guiding principles for such policies.

Maximize telemedicine and remote monitoring

Labor and delivery (L&D) is an emergency department in which people are triaged from the outside. Systems should incorporate the best guidance from the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists while reducing infection exposure to staff, laboring patients, and newborns. One way to limit traffic in the triage area is to have a seasoned clinician perform phone triage for women who think they need evaluation for labor.

Maintain universal caution and precautions

All people entering L&D should be presumed to be COVID-19 positive, according to early evidence reported from Columbia University in New York City.¹ After remote or off-site phone triage determines that evaluation is needed in L&D, a transporter could ensure that all people escorted to L&D undergo a rapid COVID-19 test, wear a mask, and wash their hands. Until point-of-care testing is available, we must adopt safety precautions, since current data suggest that asymptomatic people may shed the infectious virus.

Both vaginal and cesarean deliveries expose everyone in the room to respiratory droplets. Common sense tells us that the laboring patient and her support person should wear a mask and that caregivers should be protected with N95 masks as well as face shields. If this were standard for every laboring patient, exposure during emergency situations might be minimized.

Maximize support during labor

We should not need to ban partners and support people. Solid evidence demonstrates that support in labor improves outcomes, reduces the need for cesarean delivery, and increases patient satisfaction. We can and should protect staff and patients by requiring everyone to wear a mask.

Symptomatic patients, of course, require additional measures and personal protective equipment (PPE) to reduce the risk of infection among the health care team. These should be identical to the measures the hospital infectious disease experts have implemented in the intensive care unit.

Champion continuous quality improvement

It is our responsibility to implement continuous quality improvement processes so that we can respond to data that become available, and this begins with collecting our own local data.

We have sparse data on the risks of miscarriage, congenital anomalies, and preterm birth, but there have been anecdotal reports of both early miscarriage and premature labor. Given the known increased risk for severe disease with influenza during pregnancy, we understandably are concerned about how our pregnant patients will fare. There are also unknowns with respect to fetal exposure risk. During this pandemic we must capture such data within our own systems and share aggregated, de-identified data broadly and swiftly if real signals indicate a need for change in procedures or policy.

In the meantime, we can apply our expertise and best judgment to work within teams that include all stakeholders—administrators, nurses, engineers, pediatricians, infectious disease experts, and public members—to establish policies that respond to the best current evidence.

Protect vulnerable team members

SARS CoV-2 is highly contagious. Thus far, data do not suggest that pregnant women are at higher risk for severe disease, but we must assume that working in the hospital environment among many COVID-19 patients increases the risk for exposure. With so many current unknowns, it may be prudent to keep pregnant health care workers out of clinical areas in the hospital and reassign them to other duties when feasible. Medical students nationwide similarly have been removed from clinical rotations to minimize their exposure risk as well as to preserve scarce PPE.

These decisions are difficult for all involved, and shared decision making between administrators, clinical leaders, and pregnant staff that promotes transparency, honesty, and openness is key. Since the risk is unknown and financial consequences may result for both the hospital and the staff member, open discussion and thoughtful policies that can be revised as new information is obtained will help achieve the best possible resolution to a difficult situation.

ObGyns as servant leaders

COVID-19 challenges us to balance individual and public health considerations while also considering the economic and social consequences of actions. The emergence of this novel pathogen and its rapid global spread are frightening both to an uninformed public and to our skeptical government officials. Beyond our immediate clinical responsibilities, how should we as knowledgeable professionals respond?

Servant leaders commit to service and support and mentor those around them with empathy and collaboration. Servant leaders have the strategic vision to continuously grow, change, and improve at all times, but especially during a crisis. COVID-19 challenges us to be those servant leaders. To do so we must:

Promote and exhibit transparency by speaking truth to power and communicating with empathy for patients, staff, and those on the front lines who daily place themselves and their families at risk to ensure that we have essential services. Amplifying the needs and concerns of the frontline workers can drive those in power to develop practical and useful solutions.

Nurses and physicians have been threatened, and some actually terminated from their positions, because they publicly disclosed their institutions’ working conditions, lack of PPE, and unpreparedness. For example, a decorated US Navy captain was stripped of his command for writing a letter to drive action in managing a COVID-19 outbreak on the confined quarters of his ship. Such public health heroes have exhibited professionalism and leadership, placing the health and well-being of their colleagues, peers, and patients above their own careers. If we all spoke up with honesty and openness, we could have profound impact.

Hold ourselves and others accountable for scientific rigor and honesty. We must acknowledge what we do not know and be straightforward in discussing risks and benefits. The uncertainty surrounding the COVID-19 public health crisis has created anxiety among health care workers, public-facing workers, government officials, and the public. We should not speculate but rather speak clearly and openly about our knowledge deficits.

The US culture in health care drives us to prefer action over inaction. “Doing something” feels proactive, and we are conditioned to think of doing something as a less risky strategy than watchful waiting. In this time of uncertainty, we must be wary of unproven and potentially harmful interventions, and we must use our best judgment and expertise to study procedures and medications that have potential benefit.

Be collaborative and creative in crafting practical workarounds that can be implemented at scale. New processes implemented in the past month to accommodate our new socially and physically distant reality include telemedicine for prenatal care, home monitoring of blood pressure, remote physiologic monitoring of blood sugars for diabetic patients, reviewing digital images to provide remote wound care, and home pulse oximetry to assess COVID-19–positive patients at home.

More workarounds are needed to support women’s ongoing health needs. Our expertise should guide those strategies while we strive to optimize outcomes, minimize resource utilization, and reduce exposure risk for ourselves, our staff, and our patients.

Advocate for systems to collect and analyze robust data so we can adjust interventions rapidly as new information arises. As we navigate the pandemic, the lack of evidence to inform decisions and treatment challenges us daily. We should use the current crisis to promote strategies that will support rapid, comprehensive data collection during disasters. Knowledge truly is power, and without it we are forced to improvise and speculate.

ObGyns must insist that data collection includes all pregnancies—not only those positive for COVID-19 since the testing has been sporadic and imperfect—and that the data are stratified by age, gender, race and ethnicity, and sociodemographics. This would enable us to learn as much as possible as quickly as possible and would therefore inform our responses for the current SARS CoV-2 pandemic as well as for the next disaster.

Continue to: Acknowledge the limitations of the system...

Acknowledge the limitations of the system and be wise stewards of resources. Our health care system does not have sufficient resources to manage patients with severe COVID-19 and the “usual” emergencies like stroke, myocardial infarction, ectopic pregnancy, and broken bones.

Disaster planning should include a regional triage system that can take incoming calls and direct emergency medical technicians, ambulances, and private citizens to appropriate facilities and direct those who do not require urgent medical care away from those facilities.

We must incorporate principles from battlefield medicine, because this is a battle, and we are at war. That means there will be difficult decisions. It is better to engage a regional team of experts to create a system for triage and care delivery than for each provider and institution to be forced by a void in leadership to go it individually. We should engage with government and public health officials to optimize both cure and care. Although we are unable to save everyone, we can work to ensure comfort and care for all.

Demonstrate compassion and caring for patients and each other. During the COVID-19 pandemic crisis, we can each channel our best selves to support and protect each other physically and emotionally. Many of us chose ObGyn because it is generally a “happy” specialty. None of us entered medicine to watch people die or to be unable to comfort them, to be unable to allow their families to be with them, to be unable to “do something.”

A crucial part of disaster planning and response is to prepare for the second victims: those of us forced to keep going through our emotional distress because there is no time to debrief and process our pain. Frontline caregivers need support and help now as well as after the surge passes. We need to speak up to ensure there is adequate PPE, creative staffing, and supportive resources to help caregivers process their anxiety, fatigue, and distress.

Take the lead

Every crisis brings both risk and opportunity. The COVID-19 pandemic provides ObGyns the chance to have a louder voice and a meaningful seat at the table as new and creative policies must be implemented at every level. We can use this opportunity to recapture our roles as champions for women and leaders within our health care system.

Critical steps in servant leadership include speaking up with honesty, transparency, and openness; taking risks to disclose inequities, dangerous conditions, and inadequate resources; and committing ourselves to each other, our teams, and the public. When we take these steps, we will be the driving force for a cohesive, reasoned, structured, and compassionate response to the COVID-19 crisis. As we seize this opportunity to lead, we will rekindle our passion for medicine, caring for the sick, and protecting the well. ●

Hydroxychloroquine, which has been touted without definitive scientific support as a treatment for COVID-19 infection, has special significance for the millions of US military service members and veterans who served in Southwest Asia and other countries with endemic malaria: It’s a critical antimalarial drugs. It’s also needed for US Department of Veterans Affairs (VA) patients with rheumatoid arthritis.

On March 24, the VA Inspector General (IG) surveyed VA medical facilities to determine shortages in equipment as well as “antibiotics, sedatives, pain, and antiviral medications,” although there no known effective treatments for COVID-19. The OIG reported that 12 facilities indicated that they anticipated a shortage of medications, including hydroxychloroquine, lopinavir/ritonavir, IV immunoglobulin, and nebulizer products in the next 14 to 28 days. Facilities in West Haven, CT; Martinsburg, WV; Baltimore, MD; Washington, DC; Durham, NC; Columbia, SC; Tampa, FL; Detroit, MI; Temple, TX; Oklahoma City, OK; Aurora, CO; Seattle, WA; and Phoenix, AZ, all indicated anticipated shortages. At least one facility explicitly worried about access to medications and supplies produced in China and concern about disrupted supply chains may have concerned other facilities as well.

Nevertheless, hydroxychloroquine was at the top of mind both OIG inspectors as well as Veterans Health Administration (VHA) officials. In a formal response to the OIG survey, the VHA asserted: “We object to OIG’s assertions that a 14-day supply of chloroquine or hydroxychloroquine would have any merit. This is both inaccurate and irresponsible. There are active investigations into these drugs and many others, as discussed by Dr. Anthony Fauci. Yet no conclusions have been made on their effectiveness. To insist that a 14 days’ supply of these drugs is appropriate or not appropriate displays this dangerous lack of expertise on COVID-19 and Pandemic response.”

Hydroxychloroquine has been associated with serious adverse effects, such as cardiac arrhythmias and hypoglycemia, and its use against COVID-19 is based, so far, on thin evidence. It has shown promise in a laboratory setting against SARS-CoV-2, the virus that causes COVID-19, and in small studies with patients. Nonetheless, the Food and Drug Administration (FDA) has granted limited emergency authorization for certain uses of chloroquine and hydroxychloroquine against COVID-19. The rapid approval came apparently at the behest of the White House.

Former FDA leaders say the authorization has jeopardized research to learn the drugs’ real value in pandemic patients. They also charge that the decision undermines FDA’s scientific authority because it appears to be reacting to political advocacy. 

Despite the concerns, a run on chloroquine and hydroxychloroquine has been underway. According to a March 20 blog post by Premier, a hospital purchasing organization, orders for chloroquine and hydroxychloroquine jumped “dramatically” between March 1 and March 17, by 3,000% and 260%, respectively. Fortunately, these are older, relatively inexpensive oral drugs, Premier says, which means their manufacturing is “far less complicated” than for other drugs. To offer immediate help, Premier notes, drug makers such as Teva and Bayer have announced they will donate millions of tablets of the drugs to hospitals or the federal government for further testing.

Owing to “extraordinary public interest” in the off-label use of these drugs, numerous state boards of pharmacy have enacted emergency restrictions on the inappropriate dispensing of chloroquine and hydroxychloroquine, says the Quinism Foundation, a nonprofit organization that supports education and research on medical conditions caused by chloroquine and related drugs. And because of the very real potential for substitution of more dangerous quinolines (such as mefloquine) in place of chloroquine and hydroxychloroquine, the foundation recently called on state boards of pharmacy to enact uniform restrictions on the dispensing of all quinoline antimalarial drugs, with the understanding that any emergency use of any of these medications for public health purposes as attempted pandemic countermeasures would be best coordinated nationally through distribution from the Strategic National Stockpile.

In the meantime, research into hydroxychloroquine’s effectiveness is ongoing. “Coming at it from every angle”—that’s how Terry Welch, spokesman for the Walter Reed Army Institute of Research told Task & Purpose the Army is “leveraging specific competencies” to attack the COVID-19 problem. Among other things, WRAIR’s Emerging Infectious Diseases Branch (EIDB) is working to develop a vaccine against COVID-19 infection, including several versions of a novel vaccine candidate that has been tested in humans. WRAIR has also been conducting research into novel treatments, such as drug candidates similar to those successfully developed to treat malaria, and monoclonal antibodies.

WRAI was able to start its anti-COVID-19 research in early January—directly on the heels of the first reported cases of infection—because of the Institute’s history of researching related viruses. “If we hadn’t done that, we’d be weeks behind,” said Dr. Kayvon Modjarrad, director of EIDB.

The National Institutes of Health (NIH) has also begun a clinical trial, the Outcomes Related to COVID-19 treated with hydroxychloroquine among in-patients with symptomatic Diseases (ORCHID) study. The study will enroll more than 500 adults who are hospitalized with COVID-19 or in an emergency department awaiting hospitalization. All patients will continue to receive clinical care; some will be randomly assigned to also receive hydroxychloroquine. The first participants have been enrolled at Vanderbilt University Medical Center, in Nashville, one of the centers in the Prevention and Early Treatment of Acute Lung Injury (PETAL) Network.

In the “urgent race to find effective therapies,” NIH also launched the first clinical trial in the US to evaluate remdesivir, a broad-spectrum antiviral, as a potential treatment for COVID-19.  The trial, which started March 6 at the University of Nebraska Medical Center, is expected to conclude in May. Clinical trials of remdesivir have been ongoing in China, where the virus originated. The NIH study “takes into account” those trial designs. 

Many US hospitals are already using hydroxychloroquine as first-line therapy for COVID-19 patients, despite the lack of supportive clinical evidence. Wesley Self, MD, MPH, lead investigator in the ORCHID trial, says “[D]ata on hydroxychloroquine for the treatment of COVID-19 are urgently needed to inform clinical practice.”

Not only research is needed, but clear expression of the facts about the drugs. In March, shortly after the president began lauding hydroxychloroquine, a Phoenix man died of cardiac arrest and his wife ended up in critical care after they misguidedly ingested chloroquine phosphate, a chemical used to clean fish tanks.  “[W]e understand that people are trying to find new ways to prevent or treat this virus,” said Dr. Daniel Brooks, medical director of the Banner Poison and Drug Information Center in Phoenix, “but self-medicating is not the way to do so.”

Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, and one of the main spokespersons for science in the hydroxychloroquine debate, has continued to try to make his concerns clear: “I think we’ve got to be careful that we don’t make that majestic leap to assume this is a knockout drug,” he said in late March. “We still need to do the kinds of studies that definitively prove whether any intervention—not just this one, any intervention—is truly safe and effective.”

Hydroxychloroquine, which has been touted without definitive scientific support as a treatment for COVID-19 infection, has special significance for the millions of US military service members and veterans who served in Southwest Asia and other countries with endemic malaria: It’s a critical antimalarial drugs. It’s also needed for US Department of Veterans Affairs (VA) patients with rheumatoid arthritis.

On March 24, the VA Inspector General (IG) surveyed VA medical facilities to determine shortages in equipment as well as “antibiotics, sedatives, pain, and antiviral medications,” although there no known effective treatments for COVID-19. The OIG reported that 12 facilities indicated that they anticipated a shortage of medications, including hydroxychloroquine, lopinavir/ritonavir, IV immunoglobulin, and nebulizer products in the next 14 to 28 days. Facilities in West Haven, CT; Martinsburg, WV; Baltimore, MD; Washington, DC; Durham, NC; Columbia, SC; Tampa, FL; Detroit, MI; Temple, TX; Oklahoma City, OK; Aurora, CO; Seattle, WA; and Phoenix, AZ, all indicated anticipated shortages. At least one facility explicitly worried about access to medications and supplies produced in China and concern about disrupted supply chains may have concerned other facilities as well.

Team member and participant observations can deliver valuable insight into the effectiveness of an activity or project. Certainly, documentation of such qualitative assessment through survey questions or narratives can reveal important information for future action. This qualitative aspect was a significant consideration in the formation of an embedded health engagement team (EHET) intended to improve foreign assistance and health outcomes for global humanitarian and security cooperation activities.

Since health activities are centered on human interaction and relationships, some observation or qualitative assessment must be included to truly determine short-term local buy-in and long-term outcomes. The following observations include the direct narrative perspectives of team members from a multidisciplinary primary care EHET that add experiential depth to prior assessment of the pilot test of such teams during Continuing Promise 2011, a 9-country series of health engagement activities employed from the USNS Comfort.² The embedded team consisted of US Air Force (USAF), US Navy (USN), and nongovernmental organization (NGO) personnel working directly in a primary care clinic of the Costa Rican public health system.

This is small sample of a few team members who responded to a simple, open-ended prompt to record their impression of the EHET concept and experiences. Documenting this information should highlight the importance of seeking similar qualitative mission data for future health engagements. Standardized questionnaires have been used to evaluate health activities and have provided valuable analysis and recommendations that have advanced US Department of Defense (DoD) global health engagement.³ Captured narrative observation from the EHET pilot study is a complementary qualitative method that supports the concept of small, well prepared, culturally competent, EHETs tailored to work within a partner system rather than outside of it will achieve greater mutual benefit, including the application of better, more equitable health and health system principles.⁴ In this embedded manner, health care professionals may readily contribute to host nation health sector plans and goals while achieving military objectives, political goals, and mutual strategic interests through both military-military and military-civilian applications.

Observations and Reflections

Family Physician (Maj, Second Physician, USAF)

“Overall, the experience I had with the embedded team was truly rewarding. I hope this becomes a tool used to augment humanitarian missions. There is no way to truly understand a systems strengths and weakness except by being embedded in the clinic or hospital. For 3 days I worked alongside a bilingual physician at a local family practice clinic. The clinic did full spectrum family practice, including prenatal care. The doctor saw between 25 and 35 patients each day plus covered urgent care during lunch. Paper charting was used although the clinic is looking into electronic records. The clinic was very efficient. All team members were very aware of their roles and did their jobs with a smile and worked well together.

“Most patient encounters took between 10 and 15 minutes although the patient might stay around for IV therapy, intramuscular pain medications, or other treatments that were carried out by the nursing staff. There was a small procedure room and procedures would be performed on the same day they were identified. The nursing staff would set up everything, and in between patients the provider would complete the procedure. On the first day I mostly shadowed, but in the afternoon, I was asked to consult on some of the more complicated patients with diabetes mellitus or hypertension. On the second day I shadowed a health care provider who did not speak English and through an interpreter he asked for my input. In the afternoon the nursing staff asked me to discuss the treatment of abscesses. I discussed techniques of incision and drainage and importance of packing and proper wound care, worked with one of their wound care nurses on packing of several wounds, and consulted on a patient with a venous stasis ulcer.

“We identified an educational opportunity for the nursing staff. On the third day I brought a US certified wound care specialist and I gave a Microsoft PowerPoint presentation on venous stasis ulcers and proper wound care. The nursing staff and clinic were very receptive and asked if we would develop a patient-based educational presentation. The wound care specialist spent the afternoon giving hands-on demonstrations in the wound care clinic, and I taught technique for excisional biopsy of skin tags and moles to physicians. One of the host physicians arranged for more consultations on more of the clinic’s complicated patients, which included a staff member and a relative.”

Medical Technician (MSgt, E-7, Independent Duty Medical Technician, USAF)

“The first day I was assigned to work with the ‘auxiliaries,’ nurses working in the urgent care area at the clinic. Their urgent care area had limited equipment and supplies and included equipment such as mercury thermometers, a few stethoscopes and 1 blood pressure cuff. Their duties consisted of screening patients, starting IVs, giving injections and breathing treatments. They also had a minor surgery room where the nurses helped.

“During the observation of the placement of an IV catheter, I noticed that they were using a port and attaching a needle to the IV tubing and leaving the needle attached to the patient. I asked them about their procedure and incidents with needlesticks since they had to be pretty accurate in getting the needle through the port. The nurse stated there were a significant number of cases of needlesticks. The following day, we brought 18-g, 20-g, and 23-g IV catheters, saline locks, syringes, and our team’s junior physician and I instructed the nurses how to set up an IV without using the needle port.

“The third day at the clinic, I assisted in checking in patients (blood pressure, weight, interviews). I also helped run the immunizations clinic, assisting in giving both pediatric and adult immunizations. Since there was only 1 nurse on shift that day, we multitasked and also gave injections prescribed by the providers, such as medroxyprogesterone and dexamethasone. By far, this was the most rewarding part of the mission. I really felt as though we were part of the team and believe we truly made a difference.”

Administrator (LTC, Medical Service Corps, USN)

“I learned many items from our visit to Clinica Dr. Francisco Quintanas Area de Salud 4 Chacarita. I reviewed the business plan contained in two 1.5-inch hardbound books. Their business plan outlined the population served, projections for upcoming year, and contracts. Area 4 served 21,344 people (11,197 men and 10,147 women). The business plan reviewed historical encounter information (ie, average patient is seen 2.6 times annually, 203,285 laboratory tests were performed in 2010, no radiology capabilities) and contained metrics for key programs for upcoming year (eg, vaccinations, women wellness) that seemed similar to US Healthcare Effectiveness Data and Information Set (HEDIS) measures.

“Our partners discussed financing of the health care they provide, including money flows to and from the government, the work center, and the employees. The business plan contains contract information and costs for maintenance, utilities, personnel, and other issues that would be typical for US-based operations as well. Housekeeping, some of the secretaries, and security staff are not employees—they are contracted personnel. Money is shifted to meet unexpected needs (ie, in 2009/2010–H1N1 influenza was unanticipated). Money was taken from other programs to meet the need.

“Within the Area 4 clinics there are 94 personnel, including 15 physicians. They have a document that is similar to our Activity Manning Document, which outlines personnel billet code, name, and specialty. The Asistentes Técnicos de Atención Primaria are the personnel who conduct home visits and are a unique capability—we do not have an exact equivalent in most US health care systems. Pregnant workers are released from work 1 month prior to the due date and are expected to return to work 3 months postdelivery.”

Medical Logistics (Capt, Medical Service Corps, USAF)

“Costa Rica is still growing in aspects of national health care but has a reliable system in place it seems. Similar to many of the countries visited, it has great capacity for building, but is challenged to increase its infrastructure. In 2011, part of this was due to a recent economic decline in the nation and its health care sector. They have interaction both with other regional clinics managed under the same national health system construct (Caja Costarricense del Seguro Social) as well as with private practices and specialty services. The clinics are open only daytime business hours. Only the regional hospital is open 24/7 for emergent care.

“Supplies are distributed to the regional clinics primarily from San José (the capital and largest city), but also there are some smaller warehousing of clinical materials located around the region. One of these warehouses was in Puntarenas where our clinic was located. To get better information for future supply chain management support we would need to speak with the central distribution/suppliers of all nationalized clinic-run entities. What our partners did teach is that at a higher, national level the clinics are standardized with what they will carry and need to keep on-hand depending upon the clinic classification (ie, level 1, 2, or 3).

“Equipment is purchased similar to the DoD method: Requests are submitted toward the end of the year, the administration prioritizes the lists, and then buys what they feel is most beneficial to the clinic with the resources available. Our hosts stated that before the end of the year, it is very difficult to prioritize needs other than some of the items that they ‘always need’ because they are unlikely to receive items very low on their list. The hosts stated that they would be very interested in having a chance to receive any excess US military equipment from their priority lists if there was a mechanism to do so. In future EHET missions, advance coordination would need to occur to see if (locally compatible) equipment needs could be met through the Defense Reutilization and Marketing Office (DRMO). Alternatively, an embedded team focused on Biomedical Equipment repair could work alongside partners such as at this clinic to develop a sustainable preventive maintenance and equipment testing program. Advance coordination on equipment status would foster improvement for resourceful partner clinics such as Chacarita, with targeted involvement from US military biomedical equipment technicians.”

Discussion

These 4 firsthand accounts from a multidisciplinary, primary-care focused, EHET offers multiple preliminary evidence of the value of this small-scale embedded approach. The accounts are responses to an open-ended prompt for personal impressions and key thoughts as part of an EHET. Three of the advantages gleaned from these accounts are greater personal satisfaction, detailed insight into local operations and health systems, and deeper empathy and respect for common challenges despite health system differences compared with the US military health system.

These advantages are critical to afford the US military personnel the ability to more effectively execute engagement goals, such as meeting health needs in humanitarian assistance, advancing interoperable capacity for security cooperation, or achieving targeted training to enhance US medical operational skills. The greater personal satisfaction was evident in the team member responses that, despite mission stops in 7 prior countries, “This by far was the most rewarding part of the Continuing Promise 2011 mission” and “I hope this becomes a tool used to augment humanitarian missions.”

The descriptions by both the administrator and the logistician on the intimate details that the hosts shared with them is a testament to the rapid trust engendered by the embedded approach. There was a trust to share information as a result of acknowledged local strengths and legitimate interest in local challenges. Peer appreciation was evident; although they did not speak the same literal language, they spoke the same professional language, which was apparent even through the use of an interpreter.

A third advantage, evident from these written exchanges is a regular acknowledgement that health system issues, pursued processes, and desired outcomes are similar between different systems. There may be significant differences in actual resources and infrastructure, but some of the bureaucracy is similar. This last insight is essential to grasp in order to seek capacity building and interoperable solutions toward common goals; empathy is needed to encourage local ownership and sustainability while respecting local challenges and different problem-solving approaches and processes.

Conclusions 

The EHET concept afforded deep insight by team members into ways to partner with their hosts to target better health outcomes and meaningful partnership for potential long-term geopolitical impact. Long duration embedded teams, or recurrent insertion, in a single location will achieve greater long-term benefits because of greater health system and cultural understanding. EHETs, once accepted and refined from prototype to standard employment tool, should prove to be a more effective tool in building partnerships, building capacity, and increased security cooperation by using US military resources to support legitimate health needs either in a military-military or military-civilian setting.⁵ These firsthand accounts provide preliminary evidence that embedded teams may be a critical and needed tool to “ensure that military health engagement is appropriate, constructive, effective, and coordinated with other actors.”⁶

The doctor saw between 25 and 35 patients each day plus covered urgent care during lunch. Paper charting was used although the clinic is looking into electronic records. The clinic was very efficient. All team members were very aware of their roles and did their jobs with a smile and worked well together.

“Most patient encounters took between 10 and 15 minutes although the patient might stay around for IV therapy, intramuscular pain medications, or other treatments that were carried out by the nursing staff. There was a small procedure room and procedures would be performed on the same day they were identified. The nursing staff would set up everything, and in between patients the provider would complete the procedure. On the first day I mostly shadowed, but in the afternoon, I was asked to consult on some of the more complicated patients with diabetes mellitus or hypertension. On the second day I shadowed a health care provider who did not speak English and through an interpreter he asked for my input. In the afternoon the nursing staff asked me to discuss the treatment of abscesses. I discussed techniques of incision and drainage and importance of packing and proper wound care, worked with one of their wound care nurses on packing of several wounds, and consulted on a patient with a venous stasis ulcer.

“We identified an educational opportunity for the nursing staff. On the third day I brought a US certified wound care specialist and I gave a Microsoft PowerPoint presentation on venous stasis ulcers and proper wound care. The nursing staff and clinic were very receptive and asked if we would develop a patient-based educational presentation. The wound care specialist spent the afternoon giving hands-on demonstrations in the wound care clinic, and I taught technique for excisional biopsy of skin tags and moles to physicians. One of the host physicians arranged for more consultations on more of the clinic’s complicated patients, which included a staff member and a relative.”

“The first day I was assigned to work with the ‘auxiliaries,’ nurses working in the urgent care area at the clinic. Their urgent care area had limited equipment and supplies and included equipment such as mercury thermometers, a few stethoscopes and 1 blood pressure cuff. Their duties consisted of screening patients, starting IVs, giving injections and breathing treatments. They also had a minor surgery room where the nurses helped.

“During the observation of the placement of an IV catheter, I noticed that they were using a port and attaching a needle to the IV tubing and leaving the needle attached to the patient. I asked them about their procedure and incidents with needlesticks since they had to be pretty accurate in getting the needle through the port. The nurse stated there were a significant number of cases of needlesticks. The following day, we brought 18-g, 20-g, and 23-g IV catheters, saline locks, syringes, and our team’s junior physician and I instructed the nurses how to set up an IV without using the needle port.

“The third day at the clinic, I assisted in checking in patients (blood pressure, weight, interviews). I also helped run the immunizations clinic, assisting in giving both pediatric and adult immunizations. Since there was only 1 nurse on shift that day, we multitasked and also gave injections prescribed by the providers, such as medroxyprogesterone and dexamethasone. By far, this was the most rewarding part of the mission. I really felt as though we were part of the team and believe we truly made a difference.”

“I learned many items from our visit to Clinica Dr. Francisco Quintanas Area de Salud 4 Chacarita. I reviewed the business plan contained in two 1.5-inch hardbound books. Their business plan outlined the population served, projections for upcoming year, and contracts. Area 4 served 21,344 people (11,197 men and 10,147 women). The business plan reviewed historical encounter information (ie, average patient is seen 2.6 times annually, 203,285 laboratory tests were performed in 2010, no radiology capabilities) and contained metrics for key programs for upcoming year (eg, vaccinations, women wellness) that seemed similar to US Healthcare Effectiveness Data and Information Set (HEDIS) measures.

“Our partners discussed financing of the health care they provide, including money flows to and from the government, the work center, and the employees. The business plan contains contract information and costs for maintenance, utilities, personnel, and other issues that would be typical for US-based operations as well. Housekeeping, some of the secretaries, and security staff are not employees—they are contracted personnel. Money is shifted to meet unexpected needs (ie, in 2009/2010–H1N1 influenza was unanticipated). Money was taken from other programs to meet the need.

“Within the Area 4 clinics there are 94 personnel, including 15 physicians. They have a document that is similar to our Activity Manning Document, which outlines personnel billet code, name, and specialty. The Asistentes Técnicos de Atención Primaria are the personnel who conduct home visits and are a unique capability—we do not have an exact equivalent in most US health care systems. Pregnant workers are released from work 1 month prior to the due date and are expected to return to work 3 months postdelivery.”

“Costa Rica is still growing in aspects of national health care but has a reliable system in place it seems. Similar to many of the countries visited, it has great capacity for building, but is challenged to increase its infrastructure. In 2011, part of this was due to a recent economic decline in the nation and its health care sector. They have interaction both with other regional clinics managed under the same national health system construct (Caja Costarricense del Seguro Social) as well as with private practices and specialty services. The clinics are open only daytime business hours. Only the regional hospital is open 24/7 for emergent care.

“Supplies are distributed to the regional clinics primarily from San José (the capital and largest city), but also there are some smaller warehousing of clinical materials located around the region. One of these warehouses was in Puntarenas where our clinic was located. To get better information for future supply chain management support we would need to speak with the central distribution/suppliers of all nationalized clinic-run entities. What our partners did teach is that at a higher, national level the clinics are standardized with what they will carry and need to keep on-hand depending upon the clinic classification (ie, level 1, 2, or 3).

“Equipment is purchased similar to the DoD method: Requests are submitted toward the end of the year, the administration prioritizes the lists, and then buys what they feel is most beneficial to the clinic with the resources available. Our hosts stated that before the end of the year, it is very difficult to prioritize needs other than some of the items that they ‘always need’ because they are unlikely to receive items very low on their list. The hosts stated that they would be very interested in having a chance to receive any excess US military equipment from their priority lists if there was a mechanism to do so. In future EHET missions, advance coordination would need to occur to see if (locally compatible) equipment needs could be met through the Defense Reutilization and Marketing Office (DRMO). Alternatively, an embedded team focused on Biomedical Equipment repair could work alongside partners such as at this clinic to develop a sustainable preventive maintenance and equipment testing program. Advance coordination on equipment status would foster improvement for resourceful partner clinics such as Chacarita, with targeted involvement from US military biomedical equipment technicians.”

Discussion

These 4 firsthand accounts from a multidisciplinary, primary-care focused, EHET offers multiple preliminary evidence of the value of this small-scale embedded approach. The accounts are responses to an open-ended prompt for personal impressions and key thoughts as part of an EHET. Three of the advantages gleaned from these accounts are greater personal satisfaction, detailed insight into local operations and health systems, and deeper empathy and respect for common challenges despite health system differences compared with the US military health system.

These advantages are critical to afford the US military personnel the ability to more effectively execute engagement goals, such as meeting health needs in humanitarian assistance, advancing interoperable capacity for security cooperation, or achieving targeted training to enhance US medical operational skills. The greater personal satisfaction was evident in the team member responses that, despite mission stops in 7 prior countries, “This by far was the most rewarding part of the Continuing Promise 2011 mission” and “I hope this becomes a tool used to augment humanitarian missions.”

The descriptions by both the administrator and the logistician on the intimate details that the hosts shared with them is a testament to the rapid trust engendered by the embedded approach. There was a trust to share information as a result of acknowledged local strengths and legitimate interest in local challenges. Peer appreciation was evident; although they did not speak the same literal language, they spoke the same professional language, which was apparent even through the use of an interpreter.

A third advantage, evident from these written exchanges is a regular acknowledgement that health system issues, pursued processes, and desired outcomes are similar between different systems. There may be significant differences in actual resources and infrastructure, but some of the bureaucracy is similar. This last insight is essential to grasp in order to seek capacity building and interoperable solutions toward common goals; empathy is needed to encourage local ownership and sustainability while respecting local challenges and different problem-solving approaches and processes.

Conclusions 

The EHET concept afforded deep insight by team members into ways to partner with their hosts to target better health outcomes and meaningful partnership for potential long-term geopolitical impact. Long duration embedded teams, or recurrent insertion, in a single location will achieve greater long-term benefits because of greater health system and cultural understanding. EHETs, once accepted and refined from prototype to standard employment tool, should prove to be a more effective tool in building partnerships, building capacity, and increased security cooperation by using US military resources to support legitimate health needs either in a military-military or military-civilian setting.⁵ These firsthand accounts provide preliminary evidence that embedded teams may be a critical and needed tool to “ensure that military health engagement is appropriate, constructive, effective, and coordinated with other actors.”⁶

Team member and participant observations can deliver valuable insight into the effectiveness of an activity or project. Certainly, documentation of such qualitative assessment through survey questions or narratives can reveal important information for future action. This qualitative aspect was a significant consideration in the formation of an embedded health engagement team (EHET) intended to improve foreign assistance and health outcomes for global humanitarian and security cooperation activities.

Since health activities are centered on human interaction and relationships, some observation or qualitative assessment must be included to truly determine short-term local buy-in and long-term outcomes. The following observations include the direct narrative perspectives of team members from a multidisciplinary primary care EHET that add experiential depth to prior assessment of the pilot test of such teams during Continuing Promise 2011, a 9-country series of health engagement activities employed from the USNS Comfort.² The embedded team consisted of US Air Force (USAF), US Navy (USN), and nongovernmental organization (NGO) personnel working directly in a primary care clinic of the Costa Rican public health system.

This is small sample of a few team members who responded to a simple, open-ended prompt to record their impression of the EHET concept and experiences. Documenting this information should highlight the importance of seeking similar qualitative mission data for future health engagements. Standardized questionnaires have been used to evaluate health activities and have provided valuable analysis and recommendations that have advanced US Department of Defense (DoD) global health engagement.³ Captured narrative observation from the EHET pilot study is a complementary qualitative method that supports the concept of small, well prepared, culturally competent, EHETs tailored to work within a partner system rather than outside of it will achieve greater mutual benefit, including the application of better, more equitable health and health system principles.⁴ In this embedded manner, health care professionals may readily contribute to host nation health sector plans and goals while achieving military objectives, political goals, and mutual strategic interests through both military-military and military-civilian applications.

Since the beginning of the American Republic, servicemen have been captured and held as prisoners of war (POWs), including > 130,000 in World War II , > 7,100 in the Korean War, > 700 in the Vietnam War, and 37 in Operation Desert Storm and recent conflicts.^1,2 Also, > 80 servicewomen have been held during these conflicts.^1-3 Of those living former POWs (FPOWs), almost all are geriatric (aged > 65 years) with a significant portion aged ≥ 85 years.

The physical hardships and psychological stress endured by FPOWs have lifelong deleterious sequelae on health and social functioning.^3-5 The experiences of FPOWs are associated with higher prevalence of chronic diseases and diminished functional performance in later life as demonstrated by a survey of FPOWs from World War II.⁴ The survey assessed health and functional status in a random sample of 101 FPOWs and a group of 107 non-POW combatants from the same military operations. FPOWs reported a higher mean number of somatic symptoms than did non-POWs (7.2 vs 5.4, respectively; P = .002), a higher mean number of diagnosed health conditions (9.4 vs 7.7, respectively; P < .001), and used a greater mean number of medications (4.5 vs 3.4, respectively; P = .001). Among 15 broad categories of diagnoses, differences were found in gastrointestinal disorders (FPOWs 63% vs non-POWs 49%, P = .032), musculoskeletal disorders (FPOWs 76% vs non-POWs 60%, P = .001), and cognitive disorders (FPOWs 31% vs non-POWs 15%, P = .006). FPOWs had a significantly higher proportion of 7 extrapyramidal signs and 6 signs relating to ataxia. On the Instrumental Activities of Daily Living scale, FPOWs were more likely to be impaired than were non-POWs (33% vs 17%, respectively; P = .01). In addition, FPOWs have an increased risk of developing dementia, and this risk is doubled in FPOWs with posttraumatic stress disorder (PTSD) compared with non-FPOWs without PTSD.⁵

These data indicate that FPOW status is associated with increased risk of disability and loss of independence. Federal statutes established the presumption of a relationship between FPOW status and many comorbidities for VA disability determinations in recognition of such data and to overcome lack of medical records during POW confinement and to accord benefit of the doubt where medical science cannot conclusively link disease etiology to FPOW status, to FPOWs.

Service-Connected Conditions

The historical development of conditions with a presumption of service connection for adjudication of VA compensation/disability claims began in 1921 with the Act to Establish a Veterans’ Bureau and to Improve the Facilities.¹ The act simplified and streamlined the claims adjudication process by eliminating the need to obtain evidence on the part of the veteran. The presumption of service connection also facilitated increased accuracy and consistency in adjudications by requiring similar treatment for similar claims. This “presumptive” process relieved claimants and VA of the necessity of producing direct evidence when it was impractical to do so.

In 1970, the first presumptives specific to FPOWs were legislatively established and covered 17 diseases for a FPOW who had been confined for ≥ 30 days (Pub. L. 91-376). The 30-day confinement requirement was later relaxed, and additional presumptives were established that related to diseases that were more common among FPOWs than they were among non-FPOWs. These disorders included traumatic arthritis, stroke, heart disease, osteoporosis, peripheral neuropathy, cold injuries, as well as a variety of digestive and neuropsychiatric disorders. If a FPOW is diagnosed as having ≥ 1 of these conditions and it is judged to be ≥ 10% disabling, the condition is presumed to be a sequelae of the POW experience, and it is classified as a service-connected disability (Table).

FPOW Care And Benefits Teams

Several Veterans Health Administration (VHA) directives have been issued, including the recent VHA directive 1650, which requires that each VHA medical facility have a special Care and Benefits Team (CBT) that is charged with the evaluation and treatment of FPOWs to ensure that “FPOWs receive the highest quality care and benefit services.”⁶ CBTs must be composed of a clinician trained in internal medicine or family practice; a clinician who is certified through the VA Office of Disability and Medical Assessment to conduct General Medical Compensation and Pension evaluations; a FPOW advocate who typically is a VHA clinical social worker; and a Veterans Benefits Administration (VBA) FPOW coordinator appointed by the local VBA regional office. CBTs can be expanded to include other members as needed. The CBTs are tasked with facilitating interactions between FPOWs, the VHA, and the VBA.

CBTs face several challenges in meeting their responsibilities. For example, the POW experience often results in psychological trauma that foments denial and distrust; hence, thoughtful sensitivity to the sequelae of captivity when approaching FPOWs about personal issues, such as health care, is required. Establishing trusting relationships with FPOWs is necessary if their needs are to be effectively addressed.

While the VHA is mandated to provide priority treatment for FPOWs, including hospital, nursing home, dental, and outpatient treatment, a significant number of FPOWs do not avail themselves of benefits to which they are entitled. Often these FPOWs have not used VA programs and facilities because they are uninformed or confused about VA benefits for FPOWs. As a result, referrals of eligible FPOWs to appropriate programs can be overlooked. Maximizing the service-connected disability rating of FPOWs not only impacts the disability pensions received by these veterans, but also impacts their eligibility for VHA programs, including long-term care and Dependency and Indemnity Compensation, a monthly benefit paid to spouses, children, and/or surviving parents.

In 2013, the FPOW Committee of the South Texas Veterans Health Care System (STVHCS) noted that 40% of FPOWs in our region had no VA primary care or clinic assignment. In consideration of the commitment of the VA to care for FPOWs, the unique POW-related medical and psychological issues, the geriatric age of many FPOWs, and the surprising number of FPOWs currently not receiving VA care, we expanded the concept of the CBT team to create a specialized interdisciplinary FPOW Clinic to address the unique needs of this predominantly elderly population and to involve more FPOWs in the VA system.

The main purpose of this clinic was to advise FPOWs of all VA benefits and services to which they may be entitled by identifying overlooked FPOW presumptives. As the number of FPOWs continues to decrease, outreach to FPOWs and family members has become critical, especially as increased benefits and special services might be available to this increasingly dependent older population. An informal survey of FPOW advocates across the nation found that 21% of FPOWs had disability ratings from the VA of ≤ 60%, including some who had no VA disability rating at all. Thus, an additional goal of the project was to develop a clinic model that could be disseminated throughout the VHA.

Design

The design of the FPOW Clinic team is based on an interdisciplinary model that has proven successful in geriatric medicine.⁷ The team comprises a physician, a social worker, and a registered nurse.⁸ All members have expertise in geriatric medicine and specific training in FPOW-related issues by completing a VA employee education training session on FPOW case management. Completion of this training ensured that team members were:

• Familiar with the experiences of FPOWs as well as about the medical, psychosocial, and mental health conditions that affect FPOWs;
• Knowledgeable about FPOW presumptive conditions;
• Familiar with the VBA process for rating FPOW disability claims; and
• Capable of FPOW case coordination, workflow, and communications between the FPOW Clinic team and the VBA to avail FPOWs and their families of all eligible benefits.

In-person FPOW clinic visits and chart reviews helped identify overlooked FPOW benefits. To facilitate case management, a representative of the VBA attended the initial evaluation of each FPOW in the clinic to confirm any overlooked presumptive benefits and to familiarize FPOWs with the claims process. FPOWs were also given the choice to officially enroll in the FPOW clinic for primary care or to remain with their current health care provider. Special efforts were made to enroll those FPOWs who had no STVHCS assigned primary care clinic.

The clinic was scheduled for 4 hours every week. Initial patient visits were 2 hours each and consisted of separate evaluations by each of the 3 FPOW Clinic team members who then met as a team with the addition of the VBA representative. The purpose of this meeting was to discuss overlooked benefits, address any other specific issues noted, and to devise an appropriate interdisciplinary plan. Findings of overlooked benefits and other relevant outcomes then were conveyed to the FPOW. For FPOWs who opted to continue in the clinic for their primary care, subsequent appointments were 1 hour.

Implementation 

STVHCS FPOW advocates identified and sent letters to FPOWs announcing the opening of the clinic and its goals. Phone calls were made to each FPOW to address questions and to ascertain their interest. The FPOW advocates then worked directly with schedulers to make clinic appointments. Forty-one FPOWs responded to this initial invitation and attended the new clinic. Subsequently, this number increased through FPOW consults placed by STVHCS primary care providers.

The service-connected disability rating of clinic patients ranged from none (6% of attendees) to 100% (28% of attendees). For 34% of patients, clinic attendance resulted in identification application for overlooked presumptives. VBA evaluation resulted in increased service-connected disability ratings for nearly one-third of clinic patients. All clinic patients without a service-connected disability prior to FPOW clinic evaluation received an increased service-connected disability rating. Overall, 60% of the FPOWs who attended the clinic opted to receive their primary care at the FPOW clinic.

The FPOW Clinic successfully identified overlooked presumptives and facilitated the determination of appropriate service-connected disabilities. Interestingly, the FPOW Clinic encountered an unanticipated challenge to identifying overlooked FPOW benefits—veterans’ medical conditions that are listed by the VHA as being service-connected in the Computerized Patient Record System did not always reflect those listed officially in VBA records. This led to occasional identification of apparently overlooked FPOW presumptives that were already recognized by the VBA but not reflected in VHA records. This issue was addressed by ensuring that VBA representatives attended postclinic meetings with clinic staff and avoided the need to pursue supposedly unrecognized benefits that were recognized.

Telehealth 

At present, FPOWs from World War II outnumber those of all other conflicts; however, this group is rapidly dwindling in numbers. World War II FPOWs are aged > 85 years, and therefore among the most frail and dependent of veterans. Often they are homebound and unable to physically travel to clinics for assessment. To serve these veterans, we are modifying the FPOW Clinic to utilize telehealth. The Telehealth FPOW Clinic will obtain relevant data from review of the electronic health record and telehealth-based clinic visits. Telehealth also may be used for assessments of Vietnam War veterans (eg, Agent Orange exposure), atomic veterans, and Gulf War veterans. Once fully designed and implemented, we believe that telehealth will prove to be a cost-effective way to provide clinic benefits to rural and older veterans.

Conclusions

The VHA provides priority medical treatment to FPOWs as well as timely and appropriate assessment of their eligibility for veterans’ benefits. The complexities benefit programs established for FPOWs is often beyond the ken of VHA physicians, social workers, and nurses. Because of this unfamiliarity, referrals of eligible FPOWs to appropriate programs can be overlooked. We established a clinic-based interdisciplinary team (FPOW Clinic) that was fully trained in FPOW benefit programs to identify overlooked benefits for FPOWs and were able to increase the disability rating on approximately one-third of the FPOWs seen in the FPOW Clinic. A telehealth-based version of the FPOW clinic is now being developed.

The physical hardships and psychological stress endured by FPOWs have lifelong deleterious sequelae on health and social functioning.^3-5 The experiences of FPOWs are associated with higher prevalence of chronic diseases and diminished functional performance in later life as demonstrated by a survey of FPOWs from World War II.⁴ The survey assessed health and functional status in a random sample of 101 FPOWs and a group of 107 non-POW combatants from the same military operations. FPOWs reported a higher mean number of somatic symptoms than did non-POWs (7.2 vs 5.4, respectively; P = .002), a higher mean number of diagnosed health conditions (9.4 vs 7.7, respectively; P < .001), and used a greater mean number of medications (4.5 vs 3.4, respectively; P = .001). Among 15 broad categories of diagnoses, differences were found in gastrointestinal disorders (FPOWs 63% vs non-POWs 49%, P = .032), musculoskeletal disorders (FPOWs 76% vs non-POWs 60%, P = .001), and cognitive disorders (FPOWs 31% vs non-POWs 15%, P = .006). FPOWs had a significantly higher proportion of 7 extrapyramidal signs and 6 signs relating to ataxia. On the Instrumental Activities of Daily Living scale, FPOWs were more likely to be impaired than were non-POWs (33% vs 17%, respectively; P = .01). In addition, FPOWs have an increased risk of developing dementia, and this risk is doubled in FPOWs with posttraumatic stress disorder (PTSD) compared with non-FPOWs without PTSD.⁵

These data indicate that FPOW status is associated with increased risk of disability and loss of independence. Federal statutes established the presumption of a relationship between FPOW status and many comorbidities for VA disability determinations in recognition of such data and to overcome lack of medical records during POW confinement and to accord benefit of the doubt where medical science cannot conclusively link disease etiology to FPOW status, to FPOWs.

Service-Connected Conditions

The historical development of conditions with a presumption of service connection for adjudication of VA compensation/disability claims began in 1921 with the Act to Establish a Veterans’ Bureau and to Improve the Facilities.¹ The act simplified and streamlined the claims adjudication process by eliminating the need to obtain evidence on the part of the veteran. The presumption of service connection also facilitated increased accuracy and consistency in adjudications by requiring similar treatment for similar claims. This “presumptive” process relieved claimants and VA of the necessity of producing direct evidence when it was impractical to do so.

In 1970, the first presumptives specific to FPOWs were legislatively established and covered 17 diseases for a FPOW who had been confined for ≥ 30 days (Pub. L. 91-376). The 30-day confinement requirement was later relaxed, and additional presumptives were established that related to diseases that were more common among FPOWs than they were among non-FPOWs. These disorders included traumatic arthritis, stroke, heart disease, osteoporosis, peripheral neuropathy, cold injuries, as well as a variety of digestive and neuropsychiatric disorders. If a FPOW is diagnosed as having ≥ 1 of these conditions and it is judged to be ≥ 10% disabling, the condition is presumed to be a sequelae of the POW experience, and it is classified as a service-connected disability (Table).

FPOW Care And Benefits Teams

Several Veterans Health Administration (VHA) directives have been issued, including the recent VHA directive 1650, which requires that each VHA medical facility have a special Care and Benefits Team (CBT) that is charged with the evaluation and treatment of FPOWs to ensure that “FPOWs receive the highest quality care and benefit services.”⁶ CBTs must be composed of a clinician trained in internal medicine or family practice; a clinician who is certified through the VA Office of Disability and Medical Assessment to conduct General Medical Compensation and Pension evaluations; a FPOW advocate who typically is a VHA clinical social worker; and a Veterans Benefits Administration (VBA) FPOW coordinator appointed by the local VBA regional office. CBTs can be expanded to include other members as needed. The CBTs are tasked with facilitating interactions between FPOWs, the VHA, and the VBA.

CBTs face several challenges in meeting their responsibilities. For example, the POW experience often results in psychological trauma that foments denial and distrust; hence, thoughtful sensitivity to the sequelae of captivity when approaching FPOWs about personal issues, such as health care, is required. Establishing trusting relationships with FPOWs is necessary if their needs are to be effectively addressed.

While the VHA is mandated to provide priority treatment for FPOWs, including hospital, nursing home, dental, and outpatient treatment, a significant number of FPOWs do not avail themselves of benefits to which they are entitled. Often these FPOWs have not used VA programs and facilities because they are uninformed or confused about VA benefits for FPOWs. As a result, referrals of eligible FPOWs to appropriate programs can be overlooked. Maximizing the service-connected disability rating of FPOWs not only impacts the disability pensions received by these veterans, but also impacts their eligibility for VHA programs, including long-term care and Dependency and Indemnity Compensation, a monthly benefit paid to spouses, children, and/or surviving parents.

In 2013, the FPOW Committee of the South Texas Veterans Health Care System (STVHCS) noted that 40% of FPOWs in our region had no VA primary care or clinic assignment. In consideration of the commitment of the VA to care for FPOWs, the unique POW-related medical and psychological issues, the geriatric age of many FPOWs, and the surprising number of FPOWs currently not receiving VA care, we expanded the concept of the CBT team to create a specialized interdisciplinary FPOW Clinic to address the unique needs of this predominantly elderly population and to involve more FPOWs in the VA system.

The main purpose of this clinic was to advise FPOWs of all VA benefits and services to which they may be entitled by identifying overlooked FPOW presumptives. As the number of FPOWs continues to decrease, outreach to FPOWs and family members has become critical, especially as increased benefits and special services might be available to this increasingly dependent older population. An informal survey of FPOW advocates across the nation found that 21% of FPOWs had disability ratings from the VA of ≤ 60%, including some who had no VA disability rating at all. Thus, an additional goal of the project was to develop a clinic model that could be disseminated throughout the VHA.

Design

The design of the FPOW Clinic team is based on an interdisciplinary model that has proven successful in geriatric medicine.⁷ The team comprises a physician, a social worker, and a registered nurse.⁸ All members have expertise in geriatric medicine and specific training in FPOW-related issues by completing a VA employee education training session on FPOW case management. Completion of this training ensured that team members were:

• Familiar with the experiences of FPOWs as well as about the medical, psychosocial, and mental health conditions that affect FPOWs;
• Knowledgeable about FPOW presumptive conditions;
• Familiar with the VBA process for rating FPOW disability claims; and
• Capable of FPOW case coordination, workflow, and communications between the FPOW Clinic team and the VBA to avail FPOWs and their families of all eligible benefits.

In-person FPOW clinic visits and chart reviews helped identify overlooked FPOW benefits. To facilitate case management, a representative of the VBA attended the initial evaluation of each FPOW in the clinic to confirm any overlooked presumptive benefits and to familiarize FPOWs with the claims process. FPOWs were also given the choice to officially enroll in the FPOW clinic for primary care or to remain with their current health care provider. Special efforts were made to enroll those FPOWs who had no STVHCS assigned primary care clinic.

The clinic was scheduled for 4 hours every week. Initial patient visits were 2 hours each and consisted of separate evaluations by each of the 3 FPOW Clinic team members who then met as a team with the addition of the VBA representative. The purpose of this meeting was to discuss overlooked benefits, address any other specific issues noted, and to devise an appropriate interdisciplinary plan. Findings of overlooked benefits and other relevant outcomes then were conveyed to the FPOW. For FPOWs who opted to continue in the clinic for their primary care, subsequent appointments were 1 hour.

Implementation 

STVHCS FPOW advocates identified and sent letters to FPOWs announcing the opening of the clinic and its goals. Phone calls were made to each FPOW to address questions and to ascertain their interest. The FPOW advocates then worked directly with schedulers to make clinic appointments. Forty-one FPOWs responded to this initial invitation and attended the new clinic. Subsequently, this number increased through FPOW consults placed by STVHCS primary care providers.

The service-connected disability rating of clinic patients ranged from none (6% of attendees) to 100% (28% of attendees). For 34% of patients, clinic attendance resulted in identification application for overlooked presumptives. VBA evaluation resulted in increased service-connected disability ratings for nearly one-third of clinic patients. All clinic patients without a service-connected disability prior to FPOW clinic evaluation received an increased service-connected disability rating. Overall, 60% of the FPOWs who attended the clinic opted to receive their primary care at the FPOW clinic.

The FPOW Clinic successfully identified overlooked presumptives and facilitated the determination of appropriate service-connected disabilities. Interestingly, the FPOW Clinic encountered an unanticipated challenge to identifying overlooked FPOW benefits—veterans’ medical conditions that are listed by the VHA as being service-connected in the Computerized Patient Record System did not always reflect those listed officially in VBA records. This led to occasional identification of apparently overlooked FPOW presumptives that were already recognized by the VBA but not reflected in VHA records. This issue was addressed by ensuring that VBA representatives attended postclinic meetings with clinic staff and avoided the need to pursue supposedly unrecognized benefits that were recognized.

Telehealth 

At present, FPOWs from World War II outnumber those of all other conflicts; however, this group is rapidly dwindling in numbers. World War II FPOWs are aged > 85 years, and therefore among the most frail and dependent of veterans. Often they are homebound and unable to physically travel to clinics for assessment. To serve these veterans, we are modifying the FPOW Clinic to utilize telehealth. The Telehealth FPOW Clinic will obtain relevant data from review of the electronic health record and telehealth-based clinic visits. Telehealth also may be used for assessments of Vietnam War veterans (eg, Agent Orange exposure), atomic veterans, and Gulf War veterans. Once fully designed and implemented, we believe that telehealth will prove to be a cost-effective way to provide clinic benefits to rural and older veterans.

Conclusions

The VHA provides priority medical treatment to FPOWs as well as timely and appropriate assessment of their eligibility for veterans’ benefits. The complexities benefit programs established for FPOWs is often beyond the ken of VHA physicians, social workers, and nurses. Because of this unfamiliarity, referrals of eligible FPOWs to appropriate programs can be overlooked. We established a clinic-based interdisciplinary team (FPOW Clinic) that was fully trained in FPOW benefit programs to identify overlooked benefits for FPOWs and were able to increase the disability rating on approximately one-third of the FPOWs seen in the FPOW Clinic. A telehealth-based version of the FPOW clinic is now being developed.

Hospitals across the country encountered severe challenges as the first wave of the COVID-19 pandemic swept over them, and they anticipated much worse to come, according to a new report from the Office of Inspector General of the Department of Health and Human Services (HHS).

From March 23 to 27, the OIG interviewed 323 hospitals of several types in 46 states, the District of Columbia, and Puerto Rico. The report it pulled together from these interviews is intended to help HHS manage the crisis, rather than to review its response to the pandemic, the OIG said.

The most significant hospital challenges, the report states, were testing and caring for patients with known or suspected COVID-19 and protecting staff members. In addition, the hospitals faced challenges in maintaining or expanding their capacities to treat COVID-19 patients and ensuring the adequacy of basic supplies.

The critical shortages of ventilators, personal protective equipment (PPE), and test kits in hospitals have been widely reported by the media. But the OIG report also focused on some areas that have received less press attention.

To begin with, the shortage of tests has not only slowed the national response to the pandemic, but has had a major impact on inpatient care, according to the report’s authors. The limited number of test kits means that only symptomatic staff members and patients can be tested; in some hospitals, there aren’t even enough tests for that, and some facilities subdivided the test kits they had, the report states.

Moreover, the test results often took 7 days or more to come back from commercial or government labs, the report states. In the meantime, symptomatic patients were presumed to have the coronavirus. While awaiting the results, they had to stay in the hospital, using beds and requiring staff who could otherwise have been assigned to other patients.

The doctors and nurse who cared for these presumptive COVID-19 patients also had to take time suiting up in PPE before seeing them; much of that scarce PPE was wasted on those who were later found not to have the illness.

As one administrator explained to OIG, “Sitting with 60 patients with presumed positives in our hospital isn’t healthy for anybody.”

Delayed test results also reduced hospitals’ ability to provide care by sidelining clinicians who reported COVID-19 symptoms. In one hospital, 20% to 25% of staff were determined to be presumptively positive for COVID-19. As a result of their tests not being analyzed promptly, these doctors and nurses were prevented from providing clinical services for longer than necessary.
 

Supply Shortages

The report also described some factors contributing to mask shortages. Because of the fear factor, for example, all staff members in one hospital were wearing masks, instead of just those in designated areas. An administrator said the hospital was using 2,000 masks a day, 10 times the number before the COVID-19 crisis.

Another hospital received 2,300 N95 masks from a state reserve, but they were unusable because the elastic bands had dry-rotted.

Meanwhile, some vendors were profiteering. Masks that used to cost 50 cents now sold for $6 each, one administrator said.

To combat the supply chain disruptions, some facilities were buying PPE from nontraditional sources such as online retailers, home supply stores, paint stores, autobody supply shops, and beauty salons. Other hospitals were using non–medical-grade PPE such as construction masks and handmade masks and gowns.

Other hospitals reported they were conserving and reusing PPE to stretch their supplies. In some cases, they had even changed policies to reduce the extent and frequency of patient interactions with clinicians so the latter would have to change their gear less often.

Shortages of other critical supplies and materials were also reported. Hospitals were running out of supplies that supported patient rooms, such as IV poles, medical gas, linens, toilet paper, and food.

Hospitals across the country were also expecting or experiencing a shortage of ventilators, although none said any patients had been denied access to them. Some institutions were adapting anesthesia machines and single-use emergency transport ventilators.

Also concerning to hospitals was the shortage of intensive-care specialists and nurses to operate the ventilators and care for critically ill patients. Some facilities were training anesthesiologists, hospitalists, and other nonintensivists on how to use the lifesaving equipment.

Meanwhile, patients with COVID-19 symptoms were continuing to show up in droves at emergency departments. Hospitals were concerned about potential shortages of ICU beds, negative-pressure rooms, and isolation units. Given limited bed availability, some administrators said, it was getting hard to separate COVID-19 from non–COVID-19 patients.
 

What Hospitals Want

As the COVID-19 crisis continues to mount, many hospitals are facing financial emergencies as well, the report noted.

“Hospitals described increasing costs and decreasing revenues as a threat to their financial viability. Hospitals reported that ceasing elective procedures and other services decreased revenues at the same time that their costs have increased as they prepare for a potential surge of patients. Many hospitals reported that their cash reserves were quickly depleting, which could disrupt ongoing hospital operations,” the authors write.

This report was conducted a few days before the passage of the CURES Act, which earmarked $100 billion for hospitals on the frontline of the crisis. As a recent analysis of financial hospital data revealed, however, even with the 20% bump in Medicare payments for COVID-19 care that this cash infusion represents, many hospitals will face a cash-flow crunch within 60 to 90 days, as reported by Medscape Medical News.

Besides higher Medicare payments, the OIG report said, hospitals wanted the government to drop the 14-day waiting period for reimbursement and to offer them loans and grants.

Hospitals also want federal and state governments to relax regulations on professional licensing of, and business relationships with, doctors and other clinicians. They’d like the government to:

• Let them reassign licensed professionals within their hospitals and across healthcare networks
• Provide flexibility with respect to licensed professionals practicing across state lines
• Provide relief from regulations that may restrict using contracted staff or physicians based on business relationships

Hospitals also want federal and state governments to relax regulations on professional licensing of, and business relationships with, doctors and other clinicians. They’d like the government to:

• Let them reassign licensed professionals within their hospitals and across healthcare networks
• Provide flexibility with respect to licensed professionals practicing across state lines
• Provide relief from regulations that may restrict using contracted staff or physicians based on business relationships

Hospitals across the country encountered severe challenges as the first wave of the COVID-19 pandemic swept over them, and they anticipated much worse to come, according to a new report from the Office of Inspector General of the Department of Health and Human Services (HHS).

From March 23 to 27, the OIG interviewed 323 hospitals of several types in 46 states, the District of Columbia, and Puerto Rico. The report it pulled together from these interviews is intended to help HHS manage the crisis, rather than to review its response to the pandemic, the OIG said.

The most significant hospital challenges, the report states, were testing and caring for patients with known or suspected COVID-19 and protecting staff members. In addition, the hospitals faced challenges in maintaining or expanding their capacities to treat COVID-19 patients and ensuring the adequacy of basic supplies.

The critical shortages of ventilators, personal protective equipment (PPE), and test kits in hospitals have been widely reported by the media. But the OIG report also focused on some areas that have received less press attention.

To begin with, the shortage of tests has not only slowed the national response to the pandemic, but has had a major impact on inpatient care, according to the report’s authors. The limited number of test kits means that only symptomatic staff members and patients can be tested; in some hospitals, there aren’t even enough tests for that, and some facilities subdivided the test kits they had, the report states.

Moreover, the test results often took 7 days or more to come back from commercial or government labs, the report states. In the meantime, symptomatic patients were presumed to have the coronavirus. While awaiting the results, they had to stay in the hospital, using beds and requiring staff who could otherwise have been assigned to other patients.

The doctors and nurse who cared for these presumptive COVID-19 patients also had to take time suiting up in PPE before seeing them; much of that scarce PPE was wasted on those who were later found not to have the illness.

As one administrator explained to OIG, “Sitting with 60 patients with presumed positives in our hospital isn’t healthy for anybody.”

Delayed test results also reduced hospitals’ ability to provide care by sidelining clinicians who reported COVID-19 symptoms. In one hospital, 20% to 25% of staff were determined to be presumptively positive for COVID-19. As a result of their tests not being analyzed promptly, these doctors and nurses were prevented from providing clinical services for longer than necessary.
 

Supply Shortages

The report also described some factors contributing to mask shortages. Because of the fear factor, for example, all staff members in one hospital were wearing masks, instead of just those in designated areas. An administrator said the hospital was using 2,000 masks a day, 10 times the number before the COVID-19 crisis.

Another hospital received 2,300 N95 masks from a state reserve, but they were unusable because the elastic bands had dry-rotted.

Meanwhile, some vendors were profiteering. Masks that used to cost 50 cents now sold for $6 each, one administrator said.

To combat the supply chain disruptions, some facilities were buying PPE from nontraditional sources such as online retailers, home supply stores, paint stores, autobody supply shops, and beauty salons. Other hospitals were using non–medical-grade PPE such as construction masks and handmade masks and gowns.

Other hospitals reported they were conserving and reusing PPE to stretch their supplies. In some cases, they had even changed policies to reduce the extent and frequency of patient interactions with clinicians so the latter would have to change their gear less often.

Shortages of other critical supplies and materials were also reported. Hospitals were running out of supplies that supported patient rooms, such as IV poles, medical gas, linens, toilet paper, and food.

Hospitals across the country were also expecting or experiencing a shortage of ventilators, although none said any patients had been denied access to them. Some institutions were adapting anesthesia machines and single-use emergency transport ventilators.

Also concerning to hospitals was the shortage of intensive-care specialists and nurses to operate the ventilators and care for critically ill patients. Some facilities were training anesthesiologists, hospitalists, and other nonintensivists on how to use the lifesaving equipment.

Meanwhile, patients with COVID-19 symptoms were continuing to show up in droves at emergency departments. Hospitals were concerned about potential shortages of ICU beds, negative-pressure rooms, and isolation units. Given limited bed availability, some administrators said, it was getting hard to separate COVID-19 from non–COVID-19 patients.
 

What Hospitals Want

As the COVID-19 crisis continues to mount, many hospitals are facing financial emergencies as well, the report noted.

“Hospitals described increasing costs and decreasing revenues as a threat to their financial viability. Hospitals reported that ceasing elective procedures and other services decreased revenues at the same time that their costs have increased as they prepare for a potential surge of patients. Many hospitals reported that their cash reserves were quickly depleting, which could disrupt ongoing hospital operations,” the authors write.

This report was conducted a few days before the passage of the CURES Act, which earmarked $100 billion for hospitals on the frontline of the crisis. As a recent analysis of financial hospital data revealed, however, even with the 20% bump in Medicare payments for COVID-19 care that this cash infusion represents, many hospitals will face a cash-flow crunch within 60 to 90 days, as reported by Medscape Medical News.

Beyond asthma and chronic obstructive pulmonary disease (COPD), inhalation therapy is a mainstay in the management of bronchiectasis, cystic fibrosis, and pulmonary artery hypertension. Several US Food and Drug Administration off-label indications for inhalational medications include hypoxia secondary to acute respiratory distress syndrome (ARDS) and intraoperative and postoperative pulmonary hypertension during and following cardiac surgery, respectively.^1-11 Therapeutic delivery of aerosols to the lung may be provided via nebulization, pressurized metered-dose inhalers (pMDI), and other devices (eg, dry powder inhalers, soft-mist inhalers, and smart inhalers).¹² The most common aerosolized medications given in the clinical setting are bronchodilators.¹²

Product selection is often guided by practice guidelines (Table 1), consideration of the formulation’s advantages and disadvantages (Table 2), and/or formulary considerations. For example, current guidelines for COPD state that there is no evidence for superiority of nebulized bronchodilator therapy over handheld devices in patients who can use them properly.² Due to equivalence, nebulized formulations are commonly used in hospitals, emergency departments (EDs) and ambulatory clinics based on the drug’s unit cost. In contrast, a pMDI is often more cost-effective for use in ambulatory patients who are administering multiple doses from the same canister.

The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) recommend droplet and contact precautions for all patients suspected or diagnosed with novel coronavirus-19 (COVID-19).^13,14 Airborne precautions must be applied when performing aerosol-generating medical procedures (AGMPs), including but not limited to, open suctioning of the respiratory tract, intubation, bronchoscopy, and cardiopulmonary resuscitation (CPR). Data from the severe acute respiratory syndrome (SARS-CoV) epidemic suggest that nebulization of medication is also an AGMP.^15-17

Institutions must ensure that their health care workers (HCWs) are wearing appropriate personal protective equipment (PPE) including gloves, long-sleeved gowns, eye protection, and fit-tested particulate respirators (N95 mask) for airborne procedures and are carefully discarding PPE after use.^13,14 Due to severe shortages in available respirators in the US supply chain, the CDC has temporarily modified WHO recommendations. Face masks are now an acceptable alternative to protect HCWs from splashes and sprays from procedures not likely to generate aerosols and for cleaning of rooms, although there is no evidence to support this decision.

Internationally, HCWs are falling ill with COVID-19. Data from Italy and Spain show that about 9% to 13% of these countries’ cases are HCWs.^18,19 Within the US, the Ohio health department reports approximately 16% of cases are HCWs.²⁰ It is possible that 20% of frontline HCWs will become infected.²¹ Evolving laboratory research shows that COVID-19 remains viable in aerosols for up to 3 hours postaerosolization, thus making aerosol transmission plausible.²² Nebulizers convert liquids into aerosols and during dispersal may potentially cause secondary inhalation of fugitive emissions.²³ Since interim CDC infection control guidance is to allow only essential personnel to enter the room of patients with COVID-19, many facilities will rely on their frontline nursing staff to clean and disinfect high-touch surfaces following routine care activities.²⁴

Achieving adequate fomite disinfection following viral aerosolization may pose a significant problem for any patient receiving scheduled doses of nebulized medications. Additionally, for personnel who clean rooms following intermittent drug nebulization while wearing PPE that includes a face mask, protection from aerosolized virus may be inadequate. Subsequently, fugitive emissions from nebulized medications may potentially contribute to both nosocomial COVID-19 transmission and viral infections in the medical staff until proven otherwise by studies conducted outside of the laboratory. Prevention of infection in the medical staff is imperative since federal health care systems cannot sustain a significant loss of its workforce.

Recommendations

We recommend that health care systems stop business as usual and adopt public health recommendations issued by Canadian and Hong Kong health care authorities for the management of suspected or confirmed COVID-19 disease.^25-28 We have further clarified and expanded on these interventions. During viral pandemics, prescribers and health care systems should:

1. Deprescribe nebulized therapies on medical wards and intensive care units as an infection control measure. Also avoid use in any outpatient health care setting (eg, community-based clinics, EDs, triage).
2. Avoid initiation of nebulized unproven therapies (eg, n-acetylcysteine, hypertonic saline).¹
3. Use alternative bronchodilator formulations as appropriate (eg, oral β-2 agonist, recognizing its slower onset) before prescribing nebulized agents to patients who are uncooperative or unable to follow directions needed to use a pMDI with a spacer or have experienced a prior poor response to a pMDI with spacer (eg, OptiChamber Diamond, Philips).^25,27
4.  Limit nebulized drug utilization (eg, bronchodilators, epoprostenol) to patients who are on mechanical ventilation and will receive nebulized therapies via a closed system or to patients housed in negative pressure hospital rooms.²² Use a viral filter (eg, Salter Labs system) to decrease the spread of infection for those receiving epoprostenol via face mask.²⁵
5. Adjust procurement practices (eg, pharmacy, logistics) to address the transition from nebulized drugs to alternatives.
6. Add a safety net to the drug-ordering process by restricting new orders for nebulized therapies to the prior authorization process.²⁷ Apply the exclusion criterion of suspected or definite COVID-19.
7. Add a safety net to environmental service practices. Nursing staff should track patients who received ≥ 1 nebulizations via open (before diagnosis) or closed systems so that staff wear suitable PPE to include a N-95 mask while cleaning the room.

Conclusions

To implement the aggressive infection control guidance promulgated here, we recommend collaboration with infection control, pharmacy service (eg, prior authorization team, clinical pharmacy team, and procurement team), respiratory therapy, pulmonary and other critical care physicians, EDs, CPR committee, and other stakeholders. When making significant transitions in clinical care during a viral pandemic, guidelines must be timely, use imperative wording, and consist of easily identifiable education and/or instructions for the affected frontline staff in order to change attitudes.²⁹ Additionally, when transitioning from nebulized bronchodilators to pMDI, educational in-services should be provided to frontline staff to avoid misconceptions regarding pMDI treatment efficacy and patients’ ability to use their pMDI with spacer.³⁰

I am writing this editorial on a beautiful day in the high desert of the Southwest: a bright blue clear sky such as you see only in the mountain air, a sun warm and comforting, and birds singing as if they had not a care in the world. Spring has come early as if to dramatize the cognitive dissonance between this idyllic scene and a seemingly invincible winter of disease and death that has gripped the globe.

For now, my editorials will focus on the most threatening infectious disease outbreak since, perhaps, 1918. I have been teaching public health and pandemic ethics to health care professionals and trainees for more than a decade. I always tell the medical students, “it is not if but when” the next viral wave overwhelms society. It is human nature to disbelieve this inevitability and to ignore, dismiss, or even attack the infectious disease experts and science journalists who, like Cassandra, warn us of the return of the plague.¹

In the early 2000s, virologists were concerned that Avian influenza with a mortality rate of > 60% would mutate into a virus capable of jumping the species barrier with sustained human transmission; however, that threat has not materialized (yet).² Instead, in 2009 the H1N1 influenza pandemic struck viciously. The always capricious genetic mutations of viral combinations outwitted vaccine manufacturers, offering little protection, resulting in an estimated 12,469 deaths, tragically many of them children, young, and middle-aged people.³ In between, there were periodic eruptions of the deadly Ebola virus in Africa. In 2014, 11 Americans who had either served as health care workers or traveled in the region were treated in the US.⁴

This much abridged survey of recent pandemics reminds us of how wrong were those who returning victorious from World War II with newly developed antibiotics and at the zenith of American military medicine argued that we would also beat infectious disease.⁵ As my Army pediatrician father would tell me, “the bugs will always be smarter than the drugs.” For now, COVID-19 is outwitting those in science and medicine who are engaged in a desperate race to discover a vaccine or a drug to “stop the virus in its tracks” as the media is so fond of saying.⁶ Irresponsible news outlets are giving a panicked citizenry false hope. Experts recently testified before the US House of Representatives that according to the most optimistic estimates, a vaccine is a year away.⁷ Yet information is a double-edged sword, as the Internet also is able to communicate accurate lifesaving information from the Centers of Disease Control and Prevention and state health departments with unprecedented speed and reach.

The best chance for civilization to “flatten the curve” of the pandemic is, as it has been so many times before, through precautionary measures and preventive public health efforts. There is a reason that in 2007, readers of the prestigious British Journal of Medicine ranked public health interventions as the most important advances in medical history.⁸

The initial installment of this pandemic series will offer a primer in public health ethics. Just as almost everything else in daily life has rapidly and radically changed, from cancelled church services to school closures, so too public health ethics is significantly different in many important aspects from the clinical health ethics we are accustomed to in our practice.

The first difference is focus. In clinical health ethics the focus of the individual health care practitioner is the individual patient, but public health ethics focuses on “what we as a society do to keep people healthy.”⁹ In a pandemic when decisions must be made (to paraphrase Mr. Spock) “for the good of the many” this creates an intrinsic ethical tension for the health care practitioner whose ethos is to advocate for his or her patient.

The second difference is that in order to accomplish these communitarian aims, the law and political and cultural factors have much more influence in medical decision making than within the ideal dyad of a health care practitioner and the patient engaged in shared decision making about the patient’s health. This is nowhere more evident than in the President’s recent declaration of a public health emergency. “The Federal Government, along with State and Local governments, has taken preventive and proactive measures to slow the spread of the virus and treat those affected. . .”¹⁰ Federal and state governments can exercise wide-ranging powers that can restrict individual liberties in ways that would never be legal or ethically justifiable in the course of routine clinical care.

The third difference relates to the ethical principles that guide public health care decision making in comparison with those of clinical ethics. The primacy of autonomy in modern American medical ethics must for the health of the public sometimes yield to the overarching goal of preventing serious harm to the public and mitigating the transmission of the infection. Values such as nonmaleficence and justice become even more important than individual self-determination especially as the pandemic worsens and the demand for scarce ventilators and other life-saving resources outstrips the supply.¹¹

The fourth difference is that in nonemergent care, whether in the clinic or the hospital, the health care provider bears the primary responsibility for making decisions. Practitioners bring their knowledge and experience and patients their values and preferences to arrive at a mutually acceptable treatment plan. In stark contrast the profound and tragic life and death decisions made in a pandemic should not be left to the individual clinician who to the degree possible should remain faithful to the individual patient’s interests to preserve his or her professional integrity. Instead, decisions should be in the hands of highly trained and respected committees with diverse membership and expertise in accordance with evidence-based scientific protocols that are in response to changing pandemic conditions and the best available evidence. This process ensures that the values of consistency, transparency, and fairness which take center place in a public health emergency are the moral basis of decisions rather than ad hoc decisions that risk bias and inequity especially regarding vulnerable populations.¹¹

There is one characteristic of medical decision making that does not change whether in a routine checkup or resource allocation in an intensive care unit in a pandemic: the need to respect individual human dignity and to show compassion for the suffering of those who will not survive. In the Star Trek episode “Wrath of Khan,” Spock sacrificed himself to save his ship, his comrades, and his friends who mourned his death and honored his life.

This is nowhere more evident than in the President’s recent declaration of a public health emergency. “The Federal Government, along with State and Local governments, has taken preventive and proactive measures to slow the spread of the virus and treat those affected. . .”¹⁰ Federal and state governments can exercise wide-ranging powers that can restrict individual liberties in ways that would never be legal or ethically justifiable in the course of routine clinical care.

The third difference relates to the ethical principles that guide public health care decision making in comparison with those of clinical ethics. The primacy of autonomy in modern American medical ethics must for the health of the public sometimes yield to the overarching goal of preventing serious harm to the public and mitigating the transmission of the infection. Values such as nonmaleficence and justice become even more important than individual self-determination especially as the pandemic worsens and the demand for scarce ventilators and other life-saving resources outstrips the supply.¹¹

The fourth difference is that in nonemergent care, whether in the clinic or the hospital, the health care provider bears the primary responsibility for making decisions. Practitioners bring their knowledge and experience and patients their values and preferences to arrive at a mutually acceptable treatment plan. In stark contrast the profound and tragic life and death decisions made in a pandemic should not be left to the individual clinician who to the degree possible should remain faithful to the individual patient’s interests to preserve his or her professional integrity. Instead, decisions should be in the hands of highly trained and respected committees with diverse membership and expertise in accordance with evidence-based scientific protocols that are in response to changing pandemic conditions and the best available evidence. This process ensures that the values of consistency, transparency, and fairness which take center place in a public health emergency are the moral basis of decisions rather than ad hoc decisions that risk bias and inequity especially regarding vulnerable populations.¹¹

There is one characteristic of medical decision making that does not change whether in a routine checkup or resource allocation in an intensive care unit in a pandemic: the need to respect individual human dignity and to show compassion for the suffering of those who will not survive. In the Star Trek episode “Wrath of Khan,” Spock sacrificed himself to save his ship, his comrades, and his friends who mourned his death and honored his life.

I am writing this editorial on a beautiful day in the high desert of the Southwest: a bright blue clear sky such as you see only in the mountain air, a sun warm and comforting, and birds singing as if they had not a care in the world. Spring has come early as if to dramatize the cognitive dissonance between this idyllic scene and a seemingly invincible winter of disease and death that has gripped the globe.

For now, my editorials will focus on the most threatening infectious disease outbreak since, perhaps, 1918. I have been teaching public health and pandemic ethics to health care professionals and trainees for more than a decade. I always tell the medical students, “it is not if but when” the next viral wave overwhelms society. It is human nature to disbelieve this inevitability and to ignore, dismiss, or even attack the infectious disease experts and science journalists who, like Cassandra, warn us of the return of the plague.¹

In the early 2000s, virologists were concerned that Avian influenza with a mortality rate of > 60% would mutate into a virus capable of jumping the species barrier with sustained human transmission; however, that threat has not materialized (yet).² Instead, in 2009 the H1N1 influenza pandemic struck viciously. The always capricious genetic mutations of viral combinations outwitted vaccine manufacturers, offering little protection, resulting in an estimated 12,469 deaths, tragically many of them children, young, and middle-aged people.³ In between, there were periodic eruptions of the deadly Ebola virus in Africa. In 2014, 11 Americans who had either served as health care workers or traveled in the region were treated in the US.⁴

This much abridged survey of recent pandemics reminds us of how wrong were those who returning victorious from World War II with newly developed antibiotics and at the zenith of American military medicine argued that we would also beat infectious disease.⁵ As my Army pediatrician father would tell me, “the bugs will always be smarter than the drugs.” For now, COVID-19 is outwitting those in science and medicine who are engaged in a desperate race to discover a vaccine or a drug to “stop the virus in its tracks” as the media is so fond of saying.⁶ Irresponsible news outlets are giving a panicked citizenry false hope. Experts recently testified before the US House of Representatives that according to the most optimistic estimates, a vaccine is a year away.⁷ Yet information is a double-edged sword, as the Internet also is able to communicate accurate lifesaving information from the Centers of Disease Control and Prevention and state health departments with unprecedented speed and reach.

The best chance for civilization to “flatten the curve” of the pandemic is, as it has been so many times before, through precautionary measures and preventive public health efforts. There is a reason that in 2007, readers of the prestigious British Journal of Medicine ranked public health interventions as the most important advances in medical history.⁸

The initial installment of this pandemic series will offer a primer in public health ethics. Just as almost everything else in daily life has rapidly and radically changed, from cancelled church services to school closures, so too public health ethics is significantly different in many important aspects from the clinical health ethics we are accustomed to in our practice.

The first difference is focus. In clinical health ethics the focus of the individual health care practitioner is the individual patient, but public health ethics focuses on “what we as a society do to keep people healthy.”⁹ In a pandemic when decisions must be made (to paraphrase Mr. Spock) “for the good of the many” this creates an intrinsic ethical tension for the health care practitioner whose ethos is to advocate for his or her patient.

Abstract

Objective: Cardiothoracic (CT) surgeons at our medical center were not receiving timely notification when their coronary artery bypass graft (CABG) surgery patients were admitted to the medical center or to other hospitals. The CT surgical team worked with a health alliance in southeastern North Carolina to implement health information exchange (HIE) real-time electronic notifications for their CABG patients who presented to the hospital’s emergency department (ED) or any ED affiliated with the medical center. The alert tool notifies team members about patient encounters, driving timely clinical engagement.

Methods: The CT team provided the HIE team with the names of CABG surgery patients, which were loaded into the alert tool. When a patient on the list presented to the hospital ED or its affiliates, the alert tool sent a real-time electronic notification to the Cardiac Surgical Services nurse coordinator. This intervention prompted the assessment and disposition of CABG patients, while in the ED, by the CT surgical team.

Results: Over a 16-month period (September 2017-December 2018), the names of 614 post-CABG patients were input into the HIE for tracking. Of these patients, 47 were treated and discharged from the ED; 31 were admitted for observation; 44 were readmitted for inpatient care; and 492 did not have a qualifying event requiring a notification alert. Following implementation of this practice change, the 30-day readmission rate for patients who underwent CABG at our institution decreased from 10% to 7.2%.

Conclusion: Utilizing a real-time alert tool resulted in immediate notification of the CT team when 1 of their patients presented to the ED. This afforded the CT surgical team an opportunity to intervene in the care of their patients, which in turn led to improved quality of care, physician communication and collaboration, and patient outcomes, such as preventable 30-day readmissions.

Keywords: electronic health record; real-time electronic notification; CABG; process improvement.

Unplanned 30-day hospital readmissions of patients who have undergone coronary artery bypass graft (CABG) surgery contribute to higher overall health care costs. CABG is 1 of the conditions/procedures that the Centers for Medicare and Medicaid Services (CMS) monitors for excess readmissions.¹ Readmission rates for CABG-related conditions at 30 days post-surgery are reported to be between 16% and 20% for US hospitals.² Readmissions are not only financially costly, but also have been associated with worse patient outcomes and decreased patient satisfaction.³ Common diagnoses for post-CABG admission include atrial fibrillation, pleural effusion, and wound infection.

The facility where this project was implemented had a 10% post-CABG admission rate for patients across all payers. While this rate is below the national average of 13.2%, the cardiothoracic (CT) surgical team was not being notified in a timely manner when their post-CABG patients were readmitted. The Lean team used the A3 problem-solving process to develop strategies that would reduce these readmissions and improve the care of their patients.

We explored the use of electronic alerts in managing post-CABG patients by conducting a literature search using the terms electronic alerts in patient care, patient engagement in the emergency department, electronic alerts in CABG, real-time notifications to prevent readmission, and CABG readmission. Databases searched were PubMed, Google Scholar, Cumulative Index of Nursing and Allied Health Literature, ProQuest, and ScienceDirect. This search resulted in studies focused on the use of electronic health record (EHR) alerts as a clinical decision-support tool; for example, patient demographic and assessment data are entered into the EHR, and the clinician is prompted with “performance” recommendations (eg, consider electrocardiogram and aspirin).⁴ In a paper by Engelman and Benjamin,⁵ the authors discuss the importance of the engaged physician and note that, in their emergency department (ED), an electronic notification is sent when a postoperative patient presents; however, the notification goes to the inpatient service for timely review and disposition. There was no literature that discussed the use of an electronic alert tool as a real-time patient engagement strategy that resulted in a practice change specific to the CT surgical team.

Our process improvement project focused on alerting the CT surgical team when a post-CABG patient presented to the ED, allowing them to evaluate the patient in real time and determine whether the chief complaint was related to the CABG and whether further evaluation by the CT surgeon was required. Specifically, we wanted to determine whether a real-time electronic alert that notified the CT surgical team about post-op CABG patients presenting to the ED would result in timely patient engagement, avoidance of readmissions, and an enhanced patient experience. During this project, alerts were sent to the CT surgical team notifying them of a post-CABG patient presenting to the ED or being directly admitted from home on physician orders, a provider’s office, or inpatient rehabilitation; however, the focus of this article is specifically on the notification regarding post-CABG patients presenting to the ED.

Prior to implementing the electronic notification project, the team developed and implemented several internal and external readmission reduction and prevention strategies for CABG patients. An in-house strategy involved a process whereby patients would receive their discharge medications prior to being discharged from the hospital post-CABG, thereby avoiding potential delays in the patient obtaining medications. When examining post-CABG patient readmissions, the primary conditions that led to readmission were fluid overload, pleural effusion, and atrial fibrillation. As such, a second in-house strategy was developed for post-CABG patients presenting to the ED with atrial fibrillation. The newly established protocol allowed patients to be monitored and treated in the cardiac observation unit. In addition, external strategies, including an outpatient furosemide protocol for home health nurses and an outpatient thoracentesis program and order set, were established (eg, for patients with congestive heart failure, shortness of breath).

Methods

Setting

The regional medical center where this project was implemented is the ninth largest hospital in North Carolina and the largest county-owned public hospital in the state. It is a tertiary care center and teaching hospital with 3 hospital campuses and 855 licensed beds. The medical center was included in the 100 Safecare Hospitals list by the Safecare Group; received a grade “A” Hospital Safety Score from the Leapfrog Group; and is 1 of America’s Top 100 Hospitals for Patient Experience.

Real-Time Notification Project

A regional hospital alliance in southeastern North Carolina established a health information exchange (HIE) with its member hospitals and office-based physicians to enable electronic exchange of patient information to improve quality, safety, and efficiency in health care delivery. Our medical center is part of this alliance. The HIE is a digital platform that facilitates the sharing of information between disparate connected EHR systems, and offers a portal for practices and hospitals to access patient information across North Carolina, South Carolina (via SC HIE), and nationwide (select dialysis centers). More specifically, approved providers and team members are able to access, in real time, patient-care encounter documents from other care settings (eg, acute, post-acute, ambulatory) via the HIE. Additionally, approved care entities can query-retrieve web portal information to support patient outcome improvement strategies. A partnership discussion highlighted the opportunity to utilize the HIE’s capabilities, such as real-time notification, to facilitate workflow (eg, when a patient presents to the ED, the HIE can provide access to health information at the point of care). In this capacity, the alert tool notifies care team members about patient encounters to drive timely clinical engagement for care transitions.

In January 2017, we began discussions on using the HIE to facilitate real-time electronic tracking in the Cardiac Surgical Services department at our medical center. Persons involved in these discussions included the cardiovascular (CV) team (comprised of case managers, department managers and coordinators, program coordinators, administrators, and support services [eg, pre-admission testing and home health staff]) and CT surgeons. At that time, CABG readmissions were manually tracked, and the real-time notification tool was being used in other departments (eg, in case management for tracking readmissions). The entire team was part of the initial decision meeting to pursue this possibility. The CV team reached consensus in June 2017 and proposed extending the use of the alert tool to the post-CABG population presenting to the ED (or any ED affiliated with the medical center) or admitted directly to the medical center.

The HIE staff met with the Cardiac Surgical Services team to tailor and develop the logistics of the project, such as who would be notified and how. The goals of the project were to support appropriate care intervention, reduce preventable hospital readmissions, and improve quality of care through enhanced provider communication and engagement. To achieve these goals, on the day of discharge the Cardiac Surgical Services coordinator provided the HIE team with the names of patients who had undergone CABG surgery. This patient list was loaded into the alert tool and continually updated. At 31 days, patient names were removed from the list. When a patient on the list presented to the hospital ED, the alert tool sent 2 real-time electronic notifications, an email and a text message, to the Cardiac Surgical Services coordinator, noting that a patient event occurred. Personal information was not included in the alert in order to protect patient information and comply with Health Insurance Portability and Accountability Act regulations.

The alert prompted the Cardiac Surgical Services coordinator to securely access patient information to identify and, if necessary, visit the patient. Then, based on the information gathered by the Cardiac Surgical Services coordinator, a Situation-Background-Assessment-Recommendation report was relayed to the CT surgeon, who then determined whether intervention by the CT surgical team was warranted. This process, on average, took approximately 30 minutes to complete. This was a key change in processes, one that allowed post-CABG patients to be seen by the CT surgical team while in the ED. If the issue was related to the CABG surgery, the CT surgeons could then determine an appropriate course of action, including admission or implementation of another protocol, such as the home furosemide protocol. For patients directly admitted, the surgeon contacted the admitting provider to discuss the level of care required (ie, observation or inpatient admission and treatment).

Biweekly CV team meetings were conducted during the implementation of the real-time notification alert tool. At each meeting, updates were provided on notifications received, patients who were missed by the notification process, and how well the real-time alerts were working to enhance care and appropriate disposition.

Measurements

Clinical performance data included total notifications, total number of ED visits, ED disposition (inpatient admission, observation, discharge), total number of direct admissions, direct admissions to observation, direct inpatient admissions, and patients missed by the notification process (eg, due to data entry errors, omissions of information [suffix of junior or senior], as well as programming bugs). Finally, the number of observation admissions converted to inpatient admissions was collected and further analyzed to inform needed process changes.

The Cardiac Surgical Services coordinator collected, entered, and maintained data using Excel. Data were obtained from the EHR, recorded in Excel, and analyzed using basic descriptive statistics in an ongoing fashion. Particular attention was focused on problems with the notification process (eg, patients being missed due to errors in data entry) and summarizing information to keep the Cardiac Surgical Services team updated on the progress of the process improvement. This project did not require staff protections or considerations, and because this was not a research study Institutional Review Board approval was not required.

Results

This practice change was implemented in September 2017 and led to improvements in care quality, as evidenced by improved physician communication and collaboration. In the 16-month period from implementation through December 2018, the names of 614 post-CABG patients were input into the HIE for tracking. Of these patients, 47 were treated and discharged from the ED; 31 were admitted for observation; and 44 were readmitted for inpatient care. The remaining 492 patients did not have a qualifying event requiring a notification alert. Clinical performance data from this period included 70 ED visits, 21 direct admissions, 19 direct admissions to observation, 5 patients missed by the notification process, and 4 observation admissions converted to inpatient admissions. A reduction in the CABG readmission rate from 10% in September 2017 to 7.2% in December 2018 was also noted.

Discussion

The aim of this process improvement project was to determine whether a real-time electronic alert that notified the CT surgical team about post-op CABG patients presenting to the ED would result in timely patient engagement, avoidance of readmissions, and an enhanced patient experience. This practice change has been successful, following 16 months of implementation and process refinement. Integrating a real-time electronic alert with a supporting action plan and care protocols resulted in timely patient engagement and avoidance of readmission of post-CABG patients.

Early notification of possible post-CABG readmissions became a standard-of-care process within the Cardiac Surgical Services department, with expansion to all CT post-op patients. Leveraging HIE technology to support quality improvement processes was also viewed by other departments as relevant and beneficial. For example, the hospital stroke and orthopedic-spine teams established their own processes for receiving real-time alerts.

There were several lessons learned during this project. First, gaining 100% physician buy-in to collaborative communication proved to be critical to the project’s success. The CV team was surprised by the length of time (approximately 8-10 months) it took for the practice change to be adopted by the physicians. In part, some of this delay in adoption resulted from medical staff turnover, primarily in the medical resident training rotations. Collaborative communication was key. The CT surgeons spoke with ED leadership and hospitalist services to explain the readmission reduction project and the use of an electronic alert tool. The CT surgeons also communicated to the ED physicians, hospitalists, and cardiologists that the Cardiac Surgical Services coordinator would be involved in the process and discussions regarding patientss care. Additionally, the CT surgeons authored the furosemide protocol and then committed to its use in the home health setting, further highlighting the role of collaborative communication in avoiding readmissions.

Another key step in this quality improvement project was determining who should receive the alert notifications. At the onset of the project, all notifications were sent to 1 person, the Cardiac Surgical Services coordinator. While this seemed logical in the initial stage of the project, it was unsustainable, as the receipt of the alert and the subsequent notification of the CT surgeon depended on 1 person and their availability. Approximately 10 months into the project, the notification process was further refined, with the cardiovascular intensive care unit charge nurse becoming the point of contact for the alerts. The Cardiac Surgical Services coordinator, in collaboration with nursing leaders and CT surgeons, completed a Lean Standard Work template outlining the major steps and the associated responsibilities (for the cardiovascular intensive care unit charge nurse, CT surgeon and on-call surgeon, Cardiac Surgical Services coordinator) in the process of receiving notifications, collecting patient assessment data, and reporting notifications to the CT surgeons.

Establishing adequate support mechanisms during a practice change is also important. For instance, we had to dedicate personnel time for data collection and analysis and involve additional nursing or other qualified personnel in the new process to avoid depending on a single person for the project’s success. Additional considerations were establishing criteria for surgeon notification and defining an appropriate time frame for notification (eg, urgent versus next-day notifications). We accomplished these activities approximately 10 months into the project, after it became apparent at CV team meeting discussions that further clarification of criteria and timelines was needed.

Some aspects of the project unfolded as planned, while others presented opportunities for improvement. For example, the alert notification process worked as envisioned; however, as previously mentioned, the process needed to be more inclusive to ensure there is always a charge nurse on duty to receive the alert notification, rather than just the Cardiac Surgical Services coordinator, who may not always be at the hospital. The outpatient thoracentesis program was well planned and effectively implemented. This program provided an avenue for patients who had symptoms of pleural effusion to be treated in an outpatient setting, rather than requiring an inpatient stay. Opportunities for improvement included addressing the inconsistent use of the home health furosemide protocol (developed in 2016), and the need for continued interprofessional and interdepartmental communication and coordination. For example, we had to inform the ED physicians and staff who rotate or are new to the ED about established processes and protocols in place for managing post-CABG patients who present to the ED.

The primary limitation of this project was the inability to measure the enhanced patient experience, which was 1 of the stated project goals. This goal became secondary because of more pressing issues, specifically, interorganizational collaboration (eg, hospital EHR, HIE, and CT surgical team) and tailoring the functionality of the electronic alert tool to the project. Developing and implementing measures of enhanced patient experience were not feasible during this implementation. Additionally, because this was not a research study, it was not possible to determine cause and effect or to control for confounders, such as a sicker, older cohort with more comorbid conditions, during the comparison period. Finally, although this process improvement project was conducted at a regional medical center that is the only facility performing CABG within the region, patients may have presented to another facility for an event that led to a readmission. Because readmissions to other facilities could not be captured, it is possible that the actual readmission rate was higher than the rate reported here.

Conclusions and Implications

Utilizing a real-time alert from the HIE to the CT surgical team resulted in CT surgeons being immediately made aware when their patients presented to the ED, allowing the CT surgical team the opportunity to intervene, as appropriate, in the care of their patients. Furthermore, this real-time notification and intervention resulted in timely patient engagement and, in some cases, avoidance of readmissions. Currently, patients are monitored for readmission within 30 days of discharge. In the future, the time will expand to 91 days, in preparation for participation in the CMS bundle payment program for CABG surgery.

This practice change can be used in organizations that do not have or participate in a HIE. In fact, these real-time alert applications may be available through an EHR already in use within the organization. The use of the alert requires collaborative communication and having supporting protocols in place to guide decision-making and care of post-CABG patients presenting to the ED.

There appears to be a gap in the literature discussing the use of an electronic alert tool as a real-time patient engagement strategy for post-CABG patients presenting to the ED. As such, this project contributes important results and lessons learned for other hospital service lines/departments that might consider implementing a similar process. Next steps include designing and conducting methodologically rigorous research studies based on this process improvement project to examine mortality rates as an outcome, and designing a more specific measure of patient experience, as the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey only provides hospital-level data.

The CV team reached consensus in June 2017 and proposed extending the use of the alert tool to the post-CABG population presenting to the ED (or any ED affiliated with the medical center) or admitted directly to the medical center.

The HIE staff met with the Cardiac Surgical Services team to tailor and develop the logistics of the project, such as who would be notified and how. The goals of the project were to support appropriate care intervention, reduce preventable hospital readmissions, and improve quality of care through enhanced provider communication and engagement. To achieve these goals, on the day of discharge the Cardiac Surgical Services coordinator provided the HIE team with the names of patients who had undergone CABG surgery. This patient list was loaded into the alert tool and continually updated. At 31 days, patient names were removed from the list. When a patient on the list presented to the hospital ED, the alert tool sent 2 real-time electronic notifications, an email and a text message, to the Cardiac Surgical Services coordinator, noting that a patient event occurred. Personal information was not included in the alert in order to protect patient information and comply with Health Insurance Portability and Accountability Act regulations.

The alert prompted the Cardiac Surgical Services coordinator to securely access patient information to identify and, if necessary, visit the patient. Then, based on the information gathered by the Cardiac Surgical Services coordinator, a Situation-Background-Assessment-Recommendation report was relayed to the CT surgeon, who then determined whether intervention by the CT surgical team was warranted. This process, on average, took approximately 30 minutes to complete. This was a key change in processes, one that allowed post-CABG patients to be seen by the CT surgical team while in the ED. If the issue was related to the CABG surgery, the CT surgeons could then determine an appropriate course of action, including admission or implementation of another protocol, such as the home furosemide protocol. For patients directly admitted, the surgeon contacted the admitting provider to discuss the level of care required (ie, observation or inpatient admission and treatment).

Biweekly CV team meetings were conducted during the implementation of the real-time notification alert tool. At each meeting, updates were provided on notifications received, patients who were missed by the notification process, and how well the real-time alerts were working to enhance care and appropriate disposition.

Measurements

Clinical performance data included total notifications, total number of ED visits, ED disposition (inpatient admission, observation, discharge), total number of direct admissions, direct admissions to observation, direct inpatient admissions, and patients missed by the notification process (eg, due to data entry errors, omissions of information [suffix of junior or senior], as well as programming bugs). Finally, the number of observation admissions converted to inpatient admissions was collected and further analyzed to inform needed process changes.

The Cardiac Surgical Services coordinator collected, entered, and maintained data using Excel. Data were obtained from the EHR, recorded in Excel, and analyzed using basic descriptive statistics in an ongoing fashion. Particular attention was focused on problems with the notification process (eg, patients being missed due to errors in data entry) and summarizing information to keep the Cardiac Surgical Services team updated on the progress of the process improvement. This project did not require staff protections or considerations, and because this was not a research study Institutional Review Board approval was not required.

Results

This practice change was implemented in September 2017 and led to improvements in care quality, as evidenced by improved physician communication and collaboration. In the 16-month period from implementation through December 2018, the names of 614 post-CABG patients were input into the HIE for tracking. Of these patients, 47 were treated and discharged from the ED; 31 were admitted for observation; and 44 were readmitted for inpatient care. The remaining 492 patients did not have a qualifying event requiring a notification alert. Clinical performance data from this period included 70 ED visits, 21 direct admissions, 19 direct admissions to observation, 5 patients missed by the notification process, and 4 observation admissions converted to inpatient admissions. A reduction in the CABG readmission rate from 10% in September 2017 to 7.2% in December 2018 was also noted.

Discussion

The aim of this process improvement project was to determine whether a real-time electronic alert that notified the CT surgical team about post-op CABG patients presenting to the ED would result in timely patient engagement, avoidance of readmissions, and an enhanced patient experience. This practice change has been successful, following 16 months of implementation and process refinement. Integrating a real-time electronic alert with a supporting action plan and care protocols resulted in timely patient engagement and avoidance of readmission of post-CABG patients.

Early notification of possible post-CABG readmissions became a standard-of-care process within the Cardiac Surgical Services department, with expansion to all CT post-op patients. Leveraging HIE technology to support quality improvement processes was also viewed by other departments as relevant and beneficial. For example, the hospital stroke and orthopedic-spine teams established their own processes for receiving real-time alerts.

There were several lessons learned during this project. First, gaining 100% physician buy-in to collaborative communication proved to be critical to the project’s success. The CV team was surprised by the length of time (approximately 8-10 months) it took for the practice change to be adopted by the physicians. In part, some of this delay in adoption resulted from medical staff turnover, primarily in the medical resident training rotations. Collaborative communication was key. The CT surgeons spoke with ED leadership and hospitalist services to explain the readmission reduction project and the use of an electronic alert tool. The CT surgeons also communicated to the ED physicians, hospitalists, and cardiologists that the Cardiac Surgical Services coordinator would be involved in the process and discussions regarding patientss care. Additionally, the CT surgeons authored the furosemide protocol and then committed to its use in the home health setting, further highlighting the role of collaborative communication in avoiding readmissions.

Another key step in this quality improvement project was determining who should receive the alert notifications. At the onset of the project, all notifications were sent to 1 person, the Cardiac Surgical Services coordinator. While this seemed logical in the initial stage of the project, it was unsustainable, as the receipt of the alert and the subsequent notification of the CT surgeon depended on 1 person and their availability. Approximately 10 months into the project, the notification process was further refined, with the cardiovascular intensive care unit charge nurse becoming the point of contact for the alerts. The Cardiac Surgical Services coordinator, in collaboration with nursing leaders and CT surgeons, completed a Lean Standard Work template outlining the major steps and the associated responsibilities (for the cardiovascular intensive care unit charge nurse, CT surgeon and on-call surgeon, Cardiac Surgical Services coordinator) in the process of receiving notifications, collecting patient assessment data, and reporting notifications to the CT surgeons.

Establishing adequate support mechanisms during a practice change is also important. For instance, we had to dedicate personnel time for data collection and analysis and involve additional nursing or other qualified personnel in the new process to avoid depending on a single person for the project’s success. Additional considerations were establishing criteria for surgeon notification and defining an appropriate time frame for notification (eg, urgent versus next-day notifications). We accomplished these activities approximately 10 months into the project, after it became apparent at CV team meeting discussions that further clarification of criteria and timelines was needed.

Some aspects of the project unfolded as planned, while others presented opportunities for improvement. For example, the alert notification process worked as envisioned; however, as previously mentioned, the process needed to be more inclusive to ensure there is always a charge nurse on duty to receive the alert notification, rather than just the Cardiac Surgical Services coordinator, who may not always be at the hospital. The outpatient thoracentesis program was well planned and effectively implemented. This program provided an avenue for patients who had symptoms of pleural effusion to be treated in an outpatient setting, rather than requiring an inpatient stay. Opportunities for improvement included addressing the inconsistent use of the home health furosemide protocol (developed in 2016), and the need for continued interprofessional and interdepartmental communication and coordination. For example, we had to inform the ED physicians and staff who rotate or are new to the ED about established processes and protocols in place for managing post-CABG patients who present to the ED.

The primary limitation of this project was the inability to measure the enhanced patient experience, which was 1 of the stated project goals. This goal became secondary because of more pressing issues, specifically, interorganizational collaboration (eg, hospital EHR, HIE, and CT surgical team) and tailoring the functionality of the electronic alert tool to the project. Developing and implementing measures of enhanced patient experience were not feasible during this implementation. Additionally, because this was not a research study, it was not possible to determine cause and effect or to control for confounders, such as a sicker, older cohort with more comorbid conditions, during the comparison period. Finally, although this process improvement project was conducted at a regional medical center that is the only facility performing CABG within the region, patients may have presented to another facility for an event that led to a readmission. Because readmissions to other facilities could not be captured, it is possible that the actual readmission rate was higher than the rate reported here.

Conclusions and Implications

Utilizing a real-time alert from the HIE to the CT surgical team resulted in CT surgeons being immediately made aware when their patients presented to the ED, allowing the CT surgical team the opportunity to intervene, as appropriate, in the care of their patients. Furthermore, this real-time notification and intervention resulted in timely patient engagement and, in some cases, avoidance of readmissions. Currently, patients are monitored for readmission within 30 days of discharge. In the future, the time will expand to 91 days, in preparation for participation in the CMS bundle payment program for CABG surgery.

This practice change can be used in organizations that do not have or participate in a HIE. In fact, these real-time alert applications may be available through an EHR already in use within the organization. The use of the alert requires collaborative communication and having supporting protocols in place to guide decision-making and care of post-CABG patients presenting to the ED.

There appears to be a gap in the literature discussing the use of an electronic alert tool as a real-time patient engagement strategy for post-CABG patients presenting to the ED. As such, this project contributes important results and lessons learned for other hospital service lines/departments that might consider implementing a similar process. Next steps include designing and conducting methodologically rigorous research studies based on this process improvement project to examine mortality rates as an outcome, and designing a more specific measure of patient experience, as the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey only provides hospital-level data.

Abstract

Objective: Cardiothoracic (CT) surgeons at our medical center were not receiving timely notification when their coronary artery bypass graft (CABG) surgery patients were admitted to the medical center or to other hospitals. The CT surgical team worked with a health alliance in southeastern North Carolina to implement health information exchange (HIE) real-time electronic notifications for their CABG patients who presented to the hospital’s emergency department (ED) or any ED affiliated with the medical center. The alert tool notifies team members about patient encounters, driving timely clinical engagement.

Methods: The CT team provided the HIE team with the names of CABG surgery patients, which were loaded into the alert tool. When a patient on the list presented to the hospital ED or its affiliates, the alert tool sent a real-time electronic notification to the Cardiac Surgical Services nurse coordinator. This intervention prompted the assessment and disposition of CABG patients, while in the ED, by the CT surgical team.

Results: Over a 16-month period (September 2017-December 2018), the names of 614 post-CABG patients were input into the HIE for tracking. Of these patients, 47 were treated and discharged from the ED; 31 were admitted for observation; 44 were readmitted for inpatient care; and 492 did not have a qualifying event requiring a notification alert. Following implementation of this practice change, the 30-day readmission rate for patients who underwent CABG at our institution decreased from 10% to 7.2%.

Conclusion: Utilizing a real-time alert tool resulted in immediate notification of the CT team when 1 of their patients presented to the ED. This afforded the CT surgical team an opportunity to intervene in the care of their patients, which in turn led to improved quality of care, physician communication and collaboration, and patient outcomes, such as preventable 30-day readmissions.

Keywords: electronic health record; real-time electronic notification; CABG; process improvement.

Unplanned 30-day hospital readmissions of patients who have undergone coronary artery bypass graft (CABG) surgery contribute to higher overall health care costs. CABG is 1 of the conditions/procedures that the Centers for Medicare and Medicaid Services (CMS) monitors for excess readmissions.¹ Readmission rates for CABG-related conditions at 30 days post-surgery are reported to be between 16% and 20% for US hospitals.² Readmissions are not only financially costly, but also have been associated with worse patient outcomes and decreased patient satisfaction.³ Common diagnoses for post-CABG admission include atrial fibrillation, pleural effusion, and wound infection.

The facility where this project was implemented had a 10% post-CABG admission rate for patients across all payers. While this rate is below the national average of 13.2%, the cardiothoracic (CT) surgical team was not being notified in a timely manner when their post-CABG patients were readmitted. The Lean team used the A3 problem-solving process to develop strategies that would reduce these readmissions and improve the care of their patients.

We explored the use of electronic alerts in managing post-CABG patients by conducting a literature search using the terms electronic alerts in patient care, patient engagement in the emergency department, electronic alerts in CABG, real-time notifications to prevent readmission, and CABG readmission. Databases searched were PubMed, Google Scholar, Cumulative Index of Nursing and Allied Health Literature, ProQuest, and ScienceDirect. This search resulted in studies focused on the use of electronic health record (EHR) alerts as a clinical decision-support tool; for example, patient demographic and assessment data are entered into the EHR, and the clinician is prompted with “performance” recommendations (eg, consider electrocardiogram and aspirin).⁴ In a paper by Engelman and Benjamin,⁵ the authors discuss the importance of the engaged physician and note that, in their emergency department (ED), an electronic notification is sent when a postoperative patient presents; however, the notification goes to the inpatient service for timely review and disposition. There was no literature that discussed the use of an electronic alert tool as a real-time patient engagement strategy that resulted in a practice change specific to the CT surgical team.

Our process improvement project focused on alerting the CT surgical team when a post-CABG patient presented to the ED, allowing them to evaluate the patient in real time and determine whether the chief complaint was related to the CABG and whether further evaluation by the CT surgeon was required. Specifically, we wanted to determine whether a real-time electronic alert that notified the CT surgical team about post-op CABG patients presenting to the ED would result in timely patient engagement, avoidance of readmissions, and an enhanced patient experience. During this project, alerts were sent to the CT surgical team notifying them of a post-CABG patient presenting to the ED or being directly admitted from home on physician orders, a provider’s office, or inpatient rehabilitation; however, the focus of this article is specifically on the notification regarding post-CABG patients presenting to the ED.

Prior to implementing the electronic notification project, the team developed and implemented several internal and external readmission reduction and prevention strategies for CABG patients. An in-house strategy involved a process whereby patients would receive their discharge medications prior to being discharged from the hospital post-CABG, thereby avoiding potential delays in the patient obtaining medications. When examining post-CABG patient readmissions, the primary conditions that led to readmission were fluid overload, pleural effusion, and atrial fibrillation. As such, a second in-house strategy was developed for post-CABG patients presenting to the ED with atrial fibrillation. The newly established protocol allowed patients to be monitored and treated in the cardiac observation unit. In addition, external strategies, including an outpatient furosemide protocol for home health nurses and an outpatient thoracentesis program and order set, were established (eg, for patients with congestive heart failure, shortness of breath).

Methods

Setting

The regional medical center where this project was implemented is the ninth largest hospital in North Carolina and the largest county-owned public hospital in the state. It is a tertiary care center and teaching hospital with 3 hospital campuses and 855 licensed beds. The medical center was included in the 100 Safecare Hospitals list by the Safecare Group; received a grade “A” Hospital Safety Score from the Leapfrog Group; and is 1 of America’s Top 100 Hospitals for Patient Experience.

Real-Time Notification Project

A regional hospital alliance in southeastern North Carolina established a health information exchange (HIE) with its member hospitals and office-based physicians to enable electronic exchange of patient information to improve quality, safety, and efficiency in health care delivery. Our medical center is part of this alliance. The HIE is a digital platform that facilitates the sharing of information between disparate connected EHR systems, and offers a portal for practices and hospitals to access patient information across North Carolina, South Carolina (via SC HIE), and nationwide (select dialysis centers). More specifically, approved providers and team members are able to access, in real time, patient-care encounter documents from other care settings (eg, acute, post-acute, ambulatory) via the HIE. Additionally, approved care entities can query-retrieve web portal information to support patient outcome improvement strategies. A partnership discussion highlighted the opportunity to utilize the HIE’s capabilities, such as real-time notification, to facilitate workflow (eg, when a patient presents to the ED, the HIE can provide access to health information at the point of care). In this capacity, the alert tool notifies care team members about patient encounters to drive timely clinical engagement for care transitions.

In January 2017, we began discussions on using the HIE to facilitate real-time electronic tracking in the Cardiac Surgical Services department at our medical center. Persons involved in these discussions included the cardiovascular (CV) team (comprised of case managers, department managers and coordinators, program coordinators, administrators, and support services [eg, pre-admission testing and home health staff]) and CT surgeons. At that time, CABG readmissions were manually tracked, and the real-time notification tool was being used in other departments (eg, in case management for tracking readmissions). The entire team was part of the initial decision meeting to pursue this possibility. The CV team reached consensus in June 2017 and proposed extending the use of the alert tool to the post-CABG population presenting to the ED (or any ED affiliated with the medical center) or admitted directly to the medical center.

The HIE staff met with the Cardiac Surgical Services team to tailor and develop the logistics of the project, such as who would be notified and how. The goals of the project were to support appropriate care intervention, reduce preventable hospital readmissions, and improve quality of care through enhanced provider communication and engagement. To achieve these goals, on the day of discharge the Cardiac Surgical Services coordinator provided the HIE team with the names of patients who had undergone CABG surgery. This patient list was loaded into the alert tool and continually updated. At 31 days, patient names were removed from the list. When a patient on the list presented to the hospital ED, the alert tool sent 2 real-time electronic notifications, an email and a text message, to the Cardiac Surgical Services coordinator, noting that a patient event occurred. Personal information was not included in the alert in order to protect patient information and comply with Health Insurance Portability and Accountability Act regulations.

The alert prompted the Cardiac Surgical Services coordinator to securely access patient information to identify and, if necessary, visit the patient. Then, based on the information gathered by the Cardiac Surgical Services coordinator, a Situation-Background-Assessment-Recommendation report was relayed to the CT surgeon, who then determined whether intervention by the CT surgical team was warranted. This process, on average, took approximately 30 minutes to complete. This was a key change in processes, one that allowed post-CABG patients to be seen by the CT surgical team while in the ED.

Biweekly CV team meetings were conducted during the implementation of the real-time notification alert tool. At each meeting, updates were provided on notifications received, patients who were missed by the notification process, and how well the real-time alerts were working to enhance care and appropriate disposition.

Measurements

Clinical performance data included total notifications, total number of ED visits, ED disposition (inpatient admission, observation, discharge), total number of direct admissions, direct admissions to observation, direct inpatient admissions, and patients missed by the notification process (eg, due to data entry errors, omissions of information [suffix of junior or senior], as well as programming bugs). Finally, the number of observation admissions converted to inpatient admissions was collected and further analyzed to inform needed process changes.

The Cardiac Surgical Services coordinator collected, entered, and maintained data using Excel. Data were obtained from the EHR, recorded in Excel, and analyzed using basic descriptive statistics in an ongoing fashion. Particular attention was focused on problems with the notification process (eg, patients being missed due to errors in data entry) and summarizing information to keep the Cardiac Surgical Services team updated on the progress of the process improvement. This project did not require staff protections or considerations, and because this was not a research study Institutional Review Board approval was not required.

Abstract

• Objective: To explore factors associated with lower-extremity amputation (LEA) in patients with diabetic foot ulcers using data from the Online Wound Electronic Medical Record Database.
• Design: Retrospective analysis of medical records.
• Setting and participants: Data from 169 individuals with previously diagnosed diabetes mellitus who received wound care for a 6-month period within a span of 2 years was analyzed. A baseline evaluation was obtained and wound(s) were treated, managed, and monitored. Treatment continued until the patient healed, required an LEA, or phased out of the study, neither healing nor undergoing an amputation. Of the 149 patients who completed the study, 38 had healed ulcers, 14 underwent amputation, and 97 neither healed nor underwent an amputation. All patients were treated under the care of vascular and/or podiatric surgeons.
• Measurements: Variables included wound status (healed, amputated, and unhealed/non-amputated); size of wound area; age, gender, race, and ethnicity; white blood cell (WBC) count, hemoglobin A1c (HbA1c), blood glucose, and body mass index (BMI); and presence of osteomyelitis, gangrene, and peripheral vascular disease.
• Results: As compared to the healed and unhealed/non-amputated group, the group of patients who underwent LEA was older and had higher percentages of males, Hispanics, and African Americans; had a higher WBC count, larger wound area, and higher rates of wound infection, osteomyelitis, and neuropathy; and had lower average values of HbA1c, blood glucose, and BMI and a lower rate of peripheral vascular disease.
• Conclusion: The association between HbA1c and LEA highlights a window of relative safety among an at-risk population. By identifying and focusing on factors associated with LEA, health care professionals may be able to decrease the prevalence of LEA in patients with diabetes.

Keywords: diabetic foot ulcer; lower-extremity amputation; risk factors; HbA1c.

An estimated 30.3 million people, or 9.4% of the US population, has diabetes. In 2014, approximately 108,000 amputations were performed on adults with diagnosed diabetes.¹ Furthermore, patients with diabetes have a 10-fold increased risk for lower-extremity amputation (LEA), as compared with patients without diabetes.² The frequency of amputations in the diabetic population is a public health crisis.

Amputation has significant, life-altering consequences. Patients who undergo LEA often face debilitation in their daily activities and must undergo intense rehabilitation to learn basic tasks. Amputations can also impact individuals’ psychological well-being as they come to terms with their altered body and may face challenges in self-perception, confidence, self-esteem, work life, and relationships. In addition, the mortality rate for patients with diabetes 5 years after undergoing LEA is 30%.² However, public health studies estimate that more than half of LEAs in patients with diabetes are preventable.³

Although studies have explored the relationship between diabetes and LEA, few have sought to identify factors directly correlated with wound care. In the United States, patients with diabetic ulcerations are typically treated in wound care facilities; however, previous studies have concentrated on the conditions that lead to the formation of an ulcer or amputation, viewing amputation and ulcer as 2 separate entities. Our study took into account systemic variables, patient demographics, and specific wound characteristics to explore factors associated with LEA in a high-risk group of patients with diabetes. This study was designed to assess ailments that are prevalent in patients who require a LEA.

Methods

Patients and Setting

A total of 169 patients who were treated at the Comprehensive Wound Healing and Hyperbaric Center (Lake Success, NY), a tertiary facility of the Northwell Health system, participated in this retrospective study. The data for this study were obtained in conjunction with the development of the New York University School of Medicine’s Online Wound Electronic Medical Record to Decrease Limb Amputations in Persons with Diabetes (OWEMR) database. The OWEMR collects individual patient data from satellite locations across the country. Using this database, researchers can analyze similarities and differences between patients who undergo LEA.

This study utilized patient data specific to the Northwell Health facility. All of the patients in our study were enrolled under the criteria of the OWEMR database. In order to be included in the OWEMR database, patients had to be diagnosed with type 1 or type 2 diabetes; have a break in the skin ≥ 0.5 cm²; be 18 years of age or older; and have a measured hemoglobin A1c (HbA1c) value within the past 120 days. Study patients signed an informed consent and committed to being available for follow-up visits to the wound care facility for 6 months after entering the study. Patients were enrolled between 2012 and 2014, and each patient was monitored for a period of 6 months within this time period. Participants were treated with current standards of care using diet, lifestyle, and pharmacologic interventions. This study was approved by the Northwell Health System Institutional Review Board Human Research Protection Program (Manhasset, NY).

Data Collection

On their first visit to the facility, patients were given a physical examination and initial interview regarding their medical history. Clinicians were required to select 1 ulcer that would be examined for the duration of the study. The selection of the ulcer was based on a point system that awarded points for pedal pulses, the ability to be probed to the bone, the location of the ulcer (ie, located on the foot rather than a toe), and the presence of multiple ulcerations. The ulcer with the highest score was selected for the study. If numerous ulcers were evaluated with the same score, the largest and deepest was selected. Wagner classification of the wound was recorded at baseline and taken at each subsequent patient visit. In addition, peripheral sensation was assessed for signs of neuropathy using Semmes-Weinstein monofilament testing.

Once selected, the wound was clinically evaluated, samples for culture were obtained, and blood tests were performed to detect the presence of wound infection. The patient’s blood was drawn for a full laboratory analysis, including white blood cell (WBC) count and measurement of blood glucose and HbA1c levels. Bone biopsy, magnetic resonance imaging, and bone scans were used to detect the presence of osteomyelitis at the discretion of the health care provider. Wounds suspected of infection, underlying osteomyelitis, or gangrene at baseline were excluded. Patients would then return for follow-up visits at least once every 6 weeks, plus or minus 2 weeks, for a maximum of 6 months.

Statistical Analysis

Utilizing SAS version 9.3 (Cary, NC), descriptive statistics (minimum, maximum, mean, median, and SD) were calculated for the following variables: age, WBC count, wound area, HbA1c, blood glucose, and body mass index (BMI). These variables were collected for each patient as per the OWEMR protocol and provided a basis for which to compare patients who underwent amputation and those who did not. Twenty patients were lost to follow-up, and therefore we altered the window of our statistics from 6 months to 3 months to provide the most accurate data, as 6-month follow-up data were limited. The patients were classified into the following categories: healed, amputated, and unhealed/non-amputated. Descriptive statistics were calculated for these 3 groups, analyzing the same variables (age, WBC count, wound area, HbA1c, blood glucose, and BMI). Additional statistical computations were utilized in order to show the prevalence and frequency of our categorical variables: gender, race, ethnicity, osteomyelitis, gangrene, and peripheral vascular disease. The baseline values of WBC count, HbA1c, wound area, and BMI of the 3 groups were analyzed with descriptive statistics for comparison. A multinomial logistic regression was then performed using a 3-level outcome variable: healed, amputated, or unhealed/non-amputated. Each predictor variable was analyzed independently due to the small sample size.

Results

Of the 169 registered patients treated at the Northwell Health facility, all qualified for the OWEMR study and met the study criteria. In the original 169 patients, there were 19 amputations: 6 toe, 6 trans-metatarsal, 6 below knee, and 1 above knee (Table 1).

The descriptive statistics of 149 patients grouped into 3 categories (healed, amputated, unhealed/non-amputated) are shown in Table 2.

The results of the logistic regression exploring the differences between the amputation and healed groups and the unhealed/non-amputated group are shown in Table 3. The amputation group had a higher mean age and WBC count and greater wound area. Increased age was determined to be a significant predictor of the odds of amputation (P = 0.0089). For each year increase in age, the odds of amputation increased by 6.5% (odds ratio, 1.07 [95% confidence interval {CI}, 1.02-1.12]). Patients in the amputation group were more likely to be male, Hispanic, and African American and to have wound infections and comorbidities (osteomyelitis, neuropathy, and gangrene).

The presence of gangrene was significantly associated with LEA (P = 0.03). Specifically, the odds of patients without gangrene undergoing a LEA were substantially lower compared with their counterparts with gangrene (odds ratio, 0.17; 95% CI, 0.04-0.68; P = 0.0131). However, the presence of gangrene was not associated with the odds of healing compared with the odds of neither healing nor undergoing amputation (P = 0.84; not shown in Table 3).

The amputation group had lower mean values for HbA1c, BMI, and blood glucose levels and a lower rate of peripheral vascular disease. Only the relationship between lower HbA1c and increased odds of amputation versus not healing/non-amputation was found to be statistically significant (95% CI, 0.27-0.78; P = 0.009).

Discussion

This retrospective study was undertaken to evaluate factors associated with LEA in patients with diabetic foot ulcers. Patients with diabetes being treated at a wound care facility often require continuous surgical and metabolic intervention to promote optimal healing: drainage, surgical debridement, irrigation, culturing for infection, and monitoring of blood glucose levels. This treatment requires strict compliance with medical directions and, oftentimes, additional care, such as home-care nursing visits, to maintain a curative environment for the wound. Frequently, wounds on the lower extremity further complicate the healing process by reducing the patient’s mobility and daily life. Due to these factors, many patients progress to LEA. The link between diabetic ulcers and amputation has already been well described in previous studies, with studies showing that history of diabetic foot ulcer significantly predisposes an individual to LEA.⁴ However, few studies have further investigated demographic factors associated with risk for an amputation. Our study analyzed several categories of patient data taken from a baseline visit. We found that those with highly elevated HbA1c values were less likely to have an amputation than persons with relatively lower levels, a finding that is contrary to previous studies.

Our study’s findings suggest a higher risk for LEA with increased age. The amputation group was, on average, 7 years older than the other 2 groups. A recent study showed that risk for amputation is directly correlated to patient age, as is the mortality rate after undergoing LEA (2.3%; P < 0.05).⁵ Our study found that with each increase in age of 1 year, the odds of amputation increased by 6.5%. However, recent evidence on LEA risk and aging suggests that age is of less consequence than the duration of diabetes. One study found that the propensity to develop diabetic foot ulcers increases with the duration of diabetes.⁶ The same study found that prevalence of ulceration was correlated with age, but the relationship between age and LEA was less significant. A follow-up study for LEA could be done to examine the role of disease duration versus age in LEA.

A consensus among previous studies is that men have a higher risk for LEA.^5,7 Men comprised the majority in all 3 groups in our study. In addition, the amputation group in our study had the lowest BMI. Higher BMI generally is associated with an increased risk for health complications. However, a past study conducted in Taiwan reported that obese patients with diabetes were less likely to undergo LEA than those within the normal range for BMI.⁸ Neither study suggests that obesity is a deterrent for LEA, but both studies may suggest that risk of amputation may approach a maximum frequency at a specific BMI range, and then decrease. This unconfirmed “cyclic” relationship should be evaluated further in a larger sample size.

Most patients in our analysis were Caucasian, followed by African American and South Asian. African Americans were the only racial group with an increased frequency in the amputation group. This finding is supported by a previous study that found that the rate of LEA among patients with diabetes in low-income, predominantly African-American neighborhoods was nearly double that in wealthier, predominantly Caucasian areas.⁹ A potential problem in the comparison between our data with previous studies is that the studies did not analyze patients with our inclusion criteria. All patients with diabetes in previous investigations were grouped by race, but were not necessarily required to have 1 or more ulcers. Multiple ulcers may predispose an individual to a greater risk for amputation.

Multinomial logistic regression did not suggest an association between initial size of a patient’s wound and the risk of amputation. However, the descriptive data suggests a trend. Patients who did not heal or require an amputation had the largest average wound area. This finding is not surprising in that our study followed individuals for only 3 months. Many wounds require a long course of treatment, especially in patients with diabetes, who may have poor vascularization. However, in comparison to the healed patients, the patients who required an amputation had a larger average wound area. A larger wound requires a plentiful vascular supply for the delivery of clotting factors and nutrients to the damaged area. As wound size increases, an individual’s body must transmit an increased quantity of these factors and nutrients for the regeneration of tissue. In addition, wounds that possess a larger surface area require more debridement and present a greater opportunity for infection. This may also foreshadow a longer, more costly course of treatment. Additionally, individuals coping with large ulcerations are burdened by more elaborate and complex wound dressings.

Elevated levels of HbA1c are associated with increased adverse effects of diabetes, including end-stage renal disease, neuropathy, and infection.¹⁰ In a previous study, the risk for amputation was 1.2 times higher in patients with elevated HbA1c.¹¹ In contrast, our study suggested the odds of LEA versus not healing/not undergoing amputation decreased as HbA1c increased. As a patient’s HbA1c level increased by a value of 1, their odds for LEA decreased by 54.3%. This finding contradicts prior studies that have found a positive association between HbA1c and LEA risk, including a study where each percentage increase in HbA1c correlated with a 13% to 15% increased risk of LEA.¹² The finding that patients who underwent amputation in our study had lower levels of HbA1c and blood glucose cannot be fully explained. The maximum HbA1c value in the amputated group was 7.9%. The average values for healed patients and those who underwent LEA were 8.75% and 6.77%, respectively.

Blood glucose levels were also found to be the lowest in the amputated group in our study (mean, 149.29 mg/dL vs 163.19 mg/dL in the healed group). Similar results were found in a Brazilian study, in which patients who did not require amputation had higher HbA1c levels. This study also found an association between blood glucose levels above 200 mg/dL and amputations.³ These findings provide interesting opportunities for repeat studies, preferably with a larger number of participants.

Our study is limited by the small sample size. The sample population had to be reduced, as many patients were lost to follow-up. Although this paring down of the sample size can introduce bias, we are confident that our study is representative of the demographic of patients treated in our facility. The loss of patients to follow-up in turn caused the window of analysis to be narrowed, as long-term outcome data were not available. A multisite study observing various population samples can better explore the relationship between HbA1c and risk of amputation.

This retrospective study exploring factors associated with LEA was unique in that all our participants had 1 or more diabetic foot ulcerations, and thus already had an extremely high risk for amputation, in contrast to previous studies that followed persons at risk for developing diabetic foot ulcerations. In contrast to several previous studies, we found that the risk for amputation actually decreased as baseline measurements of HbA1c increased. The results of this study offer many opportunities for future investigations, preferably with a larger sample size. By further isolating and scrutinizing specific factors associated with LEA, researchers can help clinicians focus on providing wound care that promotes limb salvage.

Abstract

• Objective: To explore factors associated with lower-extremity amputation (LEA) in patients with diabetic foot ulcers using data from the Online Wound Electronic Medical Record Database.
• Design: Retrospective analysis of medical records.
• Setting and participants: Data from 169 individuals with previously diagnosed diabetes mellitus who received wound care for a 6-month period within a span of 2 years was analyzed. A baseline evaluation was obtained and wound(s) were treated, managed, and monitored. Treatment continued until the patient healed, required an LEA, or phased out of the study, neither healing nor undergoing an amputation. Of the 149 patients who completed the study, 38 had healed ulcers, 14 underwent amputation, and 97 neither healed nor underwent an amputation. All patients were treated under the care of vascular and/or podiatric surgeons.
• Measurements: Variables included wound status (healed, amputated, and unhealed/non-amputated); size of wound area; age, gender, race, and ethnicity; white blood cell (WBC) count, hemoglobin A1c (HbA1c), blood glucose, and body mass index (BMI); and presence of osteomyelitis, gangrene, and peripheral vascular disease.
• Results: As compared to the healed and unhealed/non-amputated group, the group of patients who underwent LEA was older and had higher percentages of males, Hispanics, and African Americans; had a higher WBC count, larger wound area, and higher rates of wound infection, osteomyelitis, and neuropathy; and had lower average values of HbA1c, blood glucose, and BMI and a lower rate of peripheral vascular disease.
• Conclusion: The association between HbA1c and LEA highlights a window of relative safety among an at-risk population. By identifying and focusing on factors associated with LEA, health care professionals may be able to decrease the prevalence of LEA in patients with diabetes.

An estimated 30.3 million people, or 9.4% of the US population, has diabetes. In 2014, approximately 108,000 amputations were performed on adults with diagnosed diabetes.¹ Furthermore, patients with diabetes have a 10-fold increased risk for lower-extremity amputation (LEA), as compared with patients without diabetes.² The frequency of amputations in the diabetic population is a public health crisis.

Amputation has significant, life-altering consequences. Patients who undergo LEA often face debilitation in their daily activities and must undergo intense rehabilitation to learn basic tasks. Amputations can also impact individuals’ psychological well-being as they come to terms with their altered body and may face challenges in self-perception, confidence, self-esteem, work life, and relationships. In addition, the mortality rate for patients with diabetes 5 years after undergoing LEA is 30%.² However, public health studies estimate that more than half of LEAs in patients with diabetes are preventable.³

Although studies have explored the relationship between diabetes and LEA, few have sought to identify factors directly correlated with wound care. In the United States, patients with diabetic ulcerations are typically treated in wound care facilities; however, previous studies have concentrated on the conditions that lead to the formation of an ulcer or amputation, viewing amputation and ulcer as 2 separate entities. Our study took into account systemic variables, patient demographics, and specific wound characteristics to explore factors associated with LEA in a high-risk group of patients with diabetes. This study was designed to assess ailments that are prevalent in patients who require a LEA.

Methods

Patients and Setting

A total of 169 patients who were treated at the Comprehensive Wound Healing and Hyperbaric Center (Lake Success, NY), a tertiary facility of the Northwell Health system, participated in this retrospective study. The data for this study were obtained in conjunction with the development of the New York University School of Medicine’s Online Wound Electronic Medical Record to Decrease Limb Amputations in Persons with Diabetes (OWEMR) database. The OWEMR collects individual patient data from satellite locations across the country. Using this database, researchers can analyze similarities and differences between patients who undergo LEA.

This study utilized patient data specific to the Northwell Health facility. All of the patients in our study were enrolled under the criteria of the OWEMR database. In order to be included in the OWEMR database, patients had to be diagnosed with type 1 or type 2 diabetes; have a break in the skin ≥ 0.5 cm²; be 18 years of age or older; and have a measured hemoglobin A1c (HbA1c) value within the past 120 days. Study patients signed an informed consent and committed to being available for follow-up visits to the wound care facility for 6 months after entering the study. Patients were enrolled between 2012 and 2014, and each patient was monitored for a period of 6 months within this time period. Participants were treated with current standards of care using diet, lifestyle, and pharmacologic interventions. This study was approved by the Northwell Health System Institutional Review Board Human Research Protection Program (Manhasset, NY).

Data Collection

On their first visit to the facility, patients were given a physical examination and initial interview regarding their medical history. Clinicians were required to select 1 ulcer that would be examined for the duration of the study. The selection of the ulcer was based on a point system that awarded points for pedal pulses, the ability to be probed to the bone, the location of the ulcer (ie, located on the foot rather than a toe), and the presence of multiple ulcerations. The ulcer with the highest score was selected for the study. If numerous ulcers were evaluated with the same score, the largest and deepest was selected. Wagner classification of the wound was recorded at baseline and taken at each subsequent patient visit. In addition, peripheral sensation was assessed for signs of neuropathy using Semmes-Weinstein monofilament testing.

Once selected, the wound was clinically evaluated, samples for culture were obtained, and blood tests were performed to detect the presence of wound infection. The patient’s blood was drawn for a full laboratory analysis, including white blood cell (WBC) count and measurement of blood glucose and HbA1c levels. Bone biopsy, magnetic resonance imaging, and bone scans were used to detect the presence of osteomyelitis at the discretion of the health care provider. Wounds suspected of infection, underlying osteomyelitis, or gangrene at baseline were excluded. Patients would then return for follow-up visits at least once every 6 weeks, plus or minus 2 weeks, for a maximum of 6 months.

Utilizing SAS version 9.3 (Cary, NC), descriptive statistics (minimum, maximum, mean, median, and SD) were calculated for the following variables: age, WBC count, wound area, HbA1c, blood glucose, and body mass index (BMI). These variables were collected for each patient as per the OWEMR protocol and provided a basis for which to compare patients who underwent amputation and those who did not. Twenty patients were lost to follow-up, and therefore we altered the window of our statistics from 6 months to 3 months to provide the most accurate data, as 6-month follow-up data were limited. The patients were classified into the following categories: healed, amputated, and unhealed/non-amputated. Descriptive statistics were calculated for these 3 groups, analyzing the same variables (age, WBC count, wound area, HbA1c, blood glucose, and BMI). Additional statistical computations were utilized in order to show the prevalence and frequency of our categorical variables: gender, race, ethnicity, osteomyelitis, gangrene, and peripheral vascular disease. The baseline values of WBC count, HbA1c, wound area, and BMI of the 3 groups were analyzed with descriptive statistics for comparison. A multinomial logistic regression was then performed using a 3-level outcome variable: healed, amputated, or unhealed/non-amputated. Each predictor variable was analyzed independently due to the small sample size.

Results

Of the 169 registered patients treated at the Northwell Health facility, all qualified for the OWEMR study and met the study criteria. In the original 169 patients, there were 19 amputations: 6 toe, 6 trans-metatarsal, 6 below knee, and 1 above knee (Table 1).

The descriptive statistics of 149 patients grouped into 3 categories (healed, amputated, unhealed/non-amputated) are shown in Table 2.

The results of the logistic regression exploring the differences between the amputation and healed groups and the unhealed/non-amputated group are shown in Table 3. The amputation group had a higher mean age and WBC count and greater wound area. Increased age was determined to be a significant predictor of the odds of amputation (P = 0.0089). For each year increase in age, the odds of amputation increased by 6.5% (odds ratio, 1.07 [95% confidence interval {CI}, 1.02-1.12]). Patients in the amputation group were more likely to be male, Hispanic, and African American and to have wound infections and comorbidities (osteomyelitis, neuropathy, and gangrene).

The presence of gangrene was significantly associated with LEA (P = 0.03). Specifically, the odds of patients without gangrene undergoing a LEA were substantially lower compared with their counterparts with gangrene (odds ratio, 0.17; 95% CI, 0.04-0.68; P = 0.0131). However, the presence of gangrene was not associated with the odds of healing compared with the odds of neither healing nor undergoing amputation (P = 0.84; not shown in Table 3).

The amputation group had lower mean values for HbA1c, BMI, and blood glucose levels and a lower rate of peripheral vascular disease. Only the relationship between lower HbA1c and increased odds of amputation versus not healing/non-amputation was found to be statistically significant (95% CI, 0.27-0.78; P = 0.009).

Discussion

This retrospective study was undertaken to evaluate factors associated with LEA in patients with diabetic foot ulcers. Patients with diabetes being treated at a wound care facility often require continuous surgical and metabolic intervention to promote optimal healing: drainage, surgical debridement, irrigation, culturing for infection, and monitoring of blood glucose levels. This treatment requires strict compliance with medical directions and, oftentimes, additional care, such as home-care nursing visits, to maintain a curative environment for the wound. Frequently, wounds on the lower extremity further complicate the healing process by reducing the patient’s mobility and daily life. Due to these factors, many patients progress to LEA. The link between diabetic ulcers and amputation has already been well described in previous studies, with studies showing that history of diabetic foot ulcer significantly predisposes an individual to LEA.⁴ However, few studies have further investigated demographic factors associated with risk for an amputation. Our study analyzed several categories of patient data taken from a baseline visit. We found that those with highly elevated HbA1c values were less likely to have an amputation than persons with relatively lower levels, a finding that is contrary to previous studies.

Our study’s findings suggest a higher risk for LEA with increased age. The amputation group was, on average, 7 years older than the other 2 groups. A recent study showed that risk for amputation is directly correlated to patient age, as is the mortality rate after undergoing LEA (2.3%; P < 0.05).⁵ Our study found that with each increase in age of 1 year, the odds of amputation increased by 6.5%. However, recent evidence on LEA risk and aging suggests that age is of less consequence than the duration of diabetes. One study found that the propensity to develop diabetic foot ulcers increases with the duration of diabetes.⁶ The same study found that prevalence of ulceration was correlated with age, but the relationship between age and LEA was less significant. A follow-up study for LEA could be done to examine the role of disease duration versus age in LEA.

A consensus among previous studies is that men have a higher risk for LEA.^5,7 Men comprised the majority in all 3 groups in our study. In addition, the amputation group in our study had the lowest BMI. Higher BMI generally is associated with an increased risk for health complications. However, a past study conducted in Taiwan reported that obese patients with diabetes were less likely to undergo LEA than those within the normal range for BMI.⁸ Neither study suggests that obesity is a deterrent for LEA, but both studies may suggest that risk of amputation may approach a maximum frequency at a specific BMI range, and then decrease. This unconfirmed “cyclic” relationship should be evaluated further in a larger sample size.

Most patients in our analysis were Caucasian, followed by African American and South Asian. African Americans were the only racial group with an increased frequency in the amputation group. This finding is supported by a previous study that found that the rate of LEA among patients with diabetes in low-income, predominantly African-American neighborhoods was nearly double that in wealthier, predominantly Caucasian areas.⁹ A potential problem in the comparison between our data with previous studies is that the studies did not analyze patients with our inclusion criteria. All patients with diabetes in previous investigations were grouped by race, but were not necessarily required to have 1 or more ulcers. Multiple ulcers may predispose an individual to a greater risk for amputation.

Multinomial logistic regression did not suggest an association between initial size of a patient’s wound and the risk of amputation. However, the descriptive data suggests a trend. Patients who did not heal or require an amputation had the largest average wound area. This finding is not surprising in that our study followed individuals for only 3 months. Many wounds require a long course of treatment, especially in patients with diabetes, who may have poor vascularization. However, in comparison to the healed patients, the patients who required an amputation had a larger average wound area. A larger wound requires a plentiful vascular supply for the delivery of clotting factors and nutrients to the damaged area. As wound size increases, an individual’s body must transmit an increased quantity of these factors and nutrients for the regeneration of tissue. In addition, wounds that possess a larger surface area require more debridement and present a greater opportunity for infection. This may also foreshadow a longer, more costly course of treatment. Additionally, individuals coping with large ulcerations are burdened by more elaborate and complex wound dressings.

Elevated levels of HbA1c are associated with increased adverse effects of diabetes, including end-stage renal disease, neuropathy, and infection.¹⁰ In a previous study, the risk for amputation was 1.2 times higher in patients with elevated HbA1c.¹¹ In contrast, our study suggested the odds of LEA versus not healing/not undergoing amputation decreased as HbA1c increased. As a patient’s HbA1c level increased by a value of 1, their odds for LEA decreased by 54.3%. This finding contradicts prior studies that have found a positive association between HbA1c and LEA risk, including a study where each percentage increase in HbA1c correlated with a 13% to 15% increased risk of LEA.¹² The finding that patients who underwent amputation in our study had lower levels of HbA1c and blood glucose cannot be fully explained. The maximum HbA1c value in the amputated group was 7.9%. The average values for healed patients and those who underwent LEA were 8.75% and 6.77%, respectively.

Blood glucose levels were also found to be the lowest in the amputated group in our study (mean, 149.29 mg/dL vs 163.19 mg/dL in the healed group). Similar results were found in a Brazilian study, in which patients who did not require amputation had higher HbA1c levels. This study also found an association between blood glucose levels above 200 mg/dL and amputations.³ These findings provide interesting opportunities for repeat studies, preferably with a larger number of participants.

Our study is limited by the small sample size. The sample population had to be reduced, as many patients were lost to follow-up. Although this paring down of the sample size can introduce bias, we are confident that our study is representative of the demographic of patients treated in our facility. The loss of patients to follow-up in turn caused the window of analysis to be narrowed, as long-term outcome data were not available. A multisite study observing various population samples can better explore the relationship between HbA1c and risk of amputation.

This retrospective study exploring factors associated with LEA was unique in that all our participants had 1 or more diabetic foot ulcerations, and thus already had an extremely high risk for amputation, in contrast to previous studies that followed persons at risk for developing diabetic foot ulcerations. In contrast to several previous studies, we found that the risk for amputation actually decreased as baseline measurements of HbA1c increased. The results of this study offer many opportunities for future investigations, preferably with a larger sample size. By further isolating and scrutinizing specific factors associated with LEA, researchers can help clinicians focus on providing wound care that promotes limb salvage.

Abstract

• Objective: To study care outcomes associated with a network of hospitalist services compared to traditional providers.
• Design: Retrospective review of administrative data.
• Setting and participants: Patients from a large integrated health care system in British Columbia in western Canada admitted and cared for by 3 provider groups between April 1, 2012, and March 31, 2018: hospitalists, family physicians (FP), and internal medicine (IM) physicians:
• Measurements: Average total length of stay (LOS), 30-day readmission, in-hospital mortality, and hospital standardized mortality ratio (HSMR) were the study outcome measures. Multiple logistic regression or generalized regression were completed to determine the relationship between provider groups and outcomes.
• Results: A total of 248,412 hospitalizations were included. Compared to patients admitted to hospitalists, patients admitted to other providers had higher odds of mortality (odds ratio [OR] for FP, 1.29; 95% confidence interval [CI], 1.21-1.37; OR for IM, 1.24; 95% CI, 1.15-1.33). Compared to hospitalist care, FP care was associated with higher readmission (OR, 1.27; 95% CI, 1.22-1.33), while IM care showed lower odds of readmission (OR, 0.83; 95% CI, 0.79-0.87). Patients admitted to the IM group had significantly lower total LOS (mean, 5.13 days; 95% CI, 5.04-5.21) compared to patients admitted to hospitalists (mean, 7.37 days; CI, 7.26-7.49) and FPs (mean, 7.30 days; 95% CI, 7.19-7.41). In a subgroup analysis of patients presenting with congestive heart failure, chronic obstructive pulmonary disease, and pneumonia, these general tendencies broadly persisted for mortality and LOS comparisons between FPs and hospitalists, but results were mixed for hospital readmissions.
• Conclusion: Care provided by hospitalists was associated with lower mortality and readmission rates compared with care provided by FPs, despite similar LOS. These findings may reflect differences in volume of services delivered by individual physicians, on-site availability to address urgent medical issues, and evolving specialization of clinical and nonclinical care processes in the acute care setting.

Keywords: hospital medicine; length of stay; readmission; mortality.

The hospitalist model of care has undergone rapid growth globally in recent years.¹ The first hospitalist programs in Canada began around the same time as those in the United States and share many similarities in design and operations with their counterparts.^2-4 However, unlike in the United States, where the hospitalist model has successfully established itself as an emerging specialty, debates about the merits of the model and its value proposition continue among Canadian observers.^5-9

Historically, the type of physicians who acted as the most responsible provider (MRP) in Canadian hospitals depended on setting and geography.¹⁰ In large urban areas, groups of general internists or specialists have historically looked after general medicine patients as part of university-affiliated teaching services.^11,12 Patients admitted to community hospitals have traditionally been cared for by their own primary care providers, typically general practitioners or family physicians (FPs). In the mid-1990s, many primary care providers in urban centers began to withdraw from inpatient care and primarily focused their practices in the outpatient setting.^13-15 Hospitalist programs emerged as health care administrators sought to fill the resulting gap in MRP coverage.^2,10

To date, attempts to understand the impact of hospitalist programs in Canada have been limited. A number of early studies aimed to describe¹⁶ the role of hospitalists in Canada and suggested improvements in length of stay (LOS) and staff satisfaction.¹⁷ However, these studies relied on unadjusted before-after comparisons and lacked methodological rigor to draw robust conclusions. More recently, a few studies have evaluated care outcomes associated with hospitalists using administrative databases, which attempted to control for potential confounding factors.^18-21

While these studies are beginning to shed some light on the impact of hospital medicine programs in Canada, there are a number of issues that limit their generalizability. For example, the majority of studies to date focus on hospital medicine programs in Canada’s largest province (Ontario), and most describe experiences from single institutions. Since each of the 13 provincial and territorial governments organizes its health care system differently,²² results from 1 province may not be generalizable to other parts of the country. Moreover, hospitalists in Ontario are more diverse in their training backgrounds, with a larger percentage having trained in general internal medicine (IM), as compared to other parts of Canada, where the majority of hospitalists are overwhelmingly trained as FPs.³

We aimed to study care outcomes associated with a network of hospitalist services compared to “traditional” providers (community-based FPs and IM specialists) in a large integrated health care system in the province of British Columbia in western Canada. The hospital medicine services in this network span a range of community and academic hospitals, and collectively constitute 1 of the largest regional programs in the country. This provides a unique opportunity to understand the impact of hospitalists on outcome measures across a range of acute care institutions.

Setting and Population

Fraser Health Authority is 1 of 5 regional health authorities in British Columbia that emerged in 2001.^23,24 It operates a network of hospitalist programs in 10 of its 12 acute care hospitals. In addition to hospitalists, there are a variable number of “traditional” physician providers who continue to act as MRPs. These include community-based FPs who continue to see their own patients in the hospital, either as part of a solo-practice model or a clinic-based call group. There are also a number of general internists and other subspecialists who accept MRP roles for general medicine patients who may present with higher-acuity conditions. As a result, patients requiring hospitalization due to nonsurgical or noncritical care conditions at each Fraser Health hospital may be cared for by a physician belonging to 1 of 3 groups, depending on local circumstances: an FP, a hospitalist, or an internist.

Inclusion and Exclusion Criteria

In order to evaluate comparative outcomes associated with hospitalist care, we included all patients admitted to a physician in each of the 3 provider groups between April 1, 2012, and March 31, 2018. We chose this time period for 2 reasons: first, we wanted to ensure comparability over an extended period of time, given the methodological changes implemented in 2009 by the Canadian Institute for Health Information (CIHI), the federal organization in the country responsible for setting standards for health care measures.²⁵ Second, previous internal reviews had suggested that data quality prior to this year was inconsistent. We only considered hospitalizations where patients were admitted to and discharged by the same service, and excluded 2 acute care facilities and 1 free-standing rehabilitation facility without a hospitalist service during this period. We also excluded patients who resided in a location beyond the geographic catchment area of Fraser Health. Further details about data collection are outlined in the Appendix.

Measures

We used the framework developed by White and Glazier²⁶ to inform the selection of our outcome measures, as well as relevant variables that may impact them. This framework proposes that the design of the inpatient care model (structures and processes of care) directly affects care outcomes. The model also proposes that patient and provider attributes can modulate this relationship, and suggests that a comprehensive evaluation of hospitalist performance needs to take these factors into account. We identified average total LOS, 30-day readmission rate, in-hospital mortality, and hospital standardized mortality ratio (HSMR)²⁷ as primary outcome measures. HSMR is defined as actual over expected mortality and is measured by CIHI through a formula that takes into account patient illness attributes (eg, the most responsible diagnosis, comorbidity levels) and baseline population mortality rates.²⁷ We chose these measures because they are clinically relevant and easy to obtain and have been utilized in previous similar studies in Canada and the United States.^18-21,26

Statistical Analysis

Baseline demographic and clinical differences in patient outcomes were examined using independent t-tests or chi-square tests. Furthermore, baseline differences based on provider groups were explored using analysis of variance or chi-square tests. Multiple logistic regression analyses were completed to determine the relationship between provider groups and readmission and mortality, while the relationship between provider groups and hospital LOS was determined with generalized linear regression (using gamma distribution and a log link). Gamma distribution with a log link analysis is appropriate with outcome measures that are positively skewed (eg, hospital LOS). It assumes that data are sampled from an exponential family of distributions, thus mimicking a log-normal distribution, and minimizes estimation bias and standard errors. These analyses were completed while controlling for the effects of age, gender, and other potential confounding factors.

We initially attempted to control for case mix by incorporating case-mix groups (CMGs) in our multivariate analysis. However, we identified 475 CMGs with at least 1 patient in our study population. We then explored the inclusion of major clinical categories (MCCs) that broadly group CMGs into various higher order/organ-system level categories (eg, diseases of the respiratory system); however, we could not aggregate them into sufficiently homogenous groups to be entered into regression models. Instead, we conducted subgroup analyses on patients in our study population who were hospitalized with 1 of the following 3 CMGs: chronic obstructive pulmonary disease (COPD, n = 11,404 patients), congestive heart failure without coronary angiography (CHF, n = 7680), and pneumonia (itself an aggregate of 3 separate CMGs: aspiration pneumonia, bacterial pneumonia, viral/unspecified pneumonia, n = 11,155). We chose these CMGs as they are among the top 8 presentations for all 3 provider groups.

For all outcome measures, we excluded atypical patients (defined by CIHI as those with atypically long stays) and patients who had been transferred between facilities. For the readmission analysis, we also excluded patients who died in the hospital (Appendix A). Data analyses were completed in IBM SPSS, version 21. For all analyses, significance was determined using 2-tailed test and alpha < 0.05.

Ethics

The Fraser Health Department of Research and Evaluation reviewed this project to determine need for formal Ethics Review Board review, and granted an exemption based on institutional guidelines for program evaluations.

Results

A total of 132,178 patients were admitted to and discharged by 1 of the 3 study provider groups during the study period, accounting for a total of 248,412 hospitalizations. After excluding patients cared for in Fraser Health facilities without a hospitalist service and those who resided in a geographic area beyond Fraser Health, a total of 224,214 admissions were included in the final analysis.

Patient Characteristics

The demographic and clinical characteristics of patients by provider group are summarized in Table 1. Patients admitted to IM providers were substantially younger than those admitted to either FPs or hospitalists (61.00 vs 70.86 and 71.22 years, respectively; P < 0.005). However, patients admitted to hospitalists had higher degrees of complexity (as measured by higher comorbidity levels, number of secondary diagnoses, and higher resource intensity weights [RIWs]; P < 000.1 for all comparisons). Overall, the most common CMGs seen by FPs and hospitalists were similar, while IM providers primarily saw patients with cardiac conditions (Table 2).

Trends Over Time

During the study period, the number of patients admitted to the hospitalist services increased by 24%, while admissions to FPs and IM providers declined steadily (Figure). During this time, LOS for hospitalists progressively declined, while LOS for FPs and IM providers increased. Similar trends were observed for measures of mortality, while readmission rates remained constant for FPs, despite a decline observed for other providers.

Table 3 summarizes the relationship between provider groups and in-hospital mortality (n = 183,779). Controlling for other variables, patients admitted to FP and IM providers had higher odds of mortality when compared to hospitalists (odds ratio [OR] for FPs, 1.29; 95% confidence interval [CI], 1.21-1.37; OR for IM, 1.24; 95% CI, 1.15-1.33). Older age, higher comorbidity level, higher number of secondary diagnoses, higher use of hospital resources (as measured by RIWs), longer than expected hospital stay (as measured by conservable days), and male gender were also associated with higher mortality. Similarly, patients receiving palliative care and those who spent at least 1 day in a special care unit (critical care, observation, and monitored care units) also had higher odds of mortality. On the other hand, admission to nonteaching medium facilities and longer hospital stay were associated with lower mortality. Compared to the first year of this analysis, lower mortality rates were observed in subsequent fiscal years. Finally, there appear to be geographic variations in mortality within Fraser Health.

Our analysis of patients with COPD, CHF, and pneumonia showed mixed results (Table 4). Patients admitted to the FP provider group with CHF and pneumonia had higher mortality compared to hospitalists (OR for CHF, 1.77; 95% CI, 1.38-2.27; OR for pneumonia, 1.53; 95% CI, 1.25-1.88), with a similar but nonstatistically significant trend observed for patients with COPD (OR, 1.29; 95% CI, 0.99-1.70). On the other hand, the higher observed mortality associated with the IM provider group in the overall study population only persisted for patients with COPD (OR, 2.71; 95% CI, 1.94-3.80), with no statistically significant differences for patients with CHF (OR, 1.18; 95% CI, 0.84-1.65) and pneumonia (OR, 0.93; 95% CI, 0.69-1.25).

We also studied adjusted mortality as measured by HSMRs. Currently, our Health Information Management system calculates an HSMR value for each patient admitted to our acute care facilities using the methodology developed by CIHI. Prior internal audits demonstrated that our internal calculations closely approximate those reported nationally. Our analysis suggests that over time, HSMR rates for the 3 provider groups have diverged, with patients admitted to IM providers having a higher mortality rate than what would be expected based on the presenting clinical conditions and comorbidity levels (Figure, part D).

Readmission

The results of our multiple logistic regression for readmission are summarized in Table 5 (n = 166,042). The impact of provider group on 30-day readmission is mixed, with higher odds associated with FPs compared to hospitalists (OR, 1.27; 95% CI, 1.22-1.34) and lower odds associated with IM physicians (OR, 0.83; 95% CI, 0.79-0.87). Gender and RIW did not show any significant associations, but increasing age, higher number of secondary diagnoses, higher comorbidity levels, and longer than expected LOS (as measure by conservable days) were associated with higher odds of readmission. Conversely, longer hospitalization, admission to a large community hospital, palliative status, admission to a special care unit, geography, and fiscal year were associated with lower odds of readmission.

The above differences between provider groups were no longer consistently present when we analyzed patients presenting with COPD, CHF, and pneumonias (Table 6). Only patients admitted to the FP provider group with pneumonia had higher odds of readmission compared to hospitalists (OR, 1.27; 95% CI, 1.05-1.54). Conversely, only patients admitted to the IM provider group with CHF showed lower readmission (OR, 0.75; 95% CI, 0.62-0.92).

Results using generalized linear regressions for total LOS are presented in Table 7 (n = 183,779). Patients admitted to the IM provider group had significantly lower total LOS (mean, 5.13 days; 95% CI, 5.04-5.21) compared to the hospitalist (mean, 7.37 days; 95% CI, 7.26-7.49) and FP (mean, 7.30 days; 95% CI, 7.19-7.41) groups, with no significant differences between the latter 2 groups. Older patients, females, patients with higher comorbidity levels or number of secondary diagnoses, higher RIW, palliative patients, and discharge to a facility other than the patient’s home were associated with a significantly longer LOS. On the other hand, admission to nonteaching hospitals and admission to a special care unit was associated with lower LOS.

When we compared total LOS for patients admitted with COPD, CHF, and pneumonias, the same differences observed for the broader comparisons persisted: IM patients consistently showed shorter LOS compared to hospitalist patients, while LOS associated with FP patients was similar (Table 8).

Discussion

To our knowledge, our evaluation is the largest study to date designed to understand outcomes associated with hospitalist care in Canada. Our analyses suggest that patients admitted to our large network of hospitalist services present with clinical conditions that are very similar to those of general medicine patients in other Canadian provinces.^28,29 They also show that patients cared for by hospitalists experience lower mortality rates compared to those cared for by FPs. Our findings are similar to previous studies, which have suggested a 12% to 75% reduction in odds of mortality associated with hospitalist care.^18,19 These differences persisted even when we focused on patients presenting with specific clinical conditions (CHF, COPD, and pneumonias).

White and colleagues have previously demonstrated that generalist physicians who had higher volumes of inpatient care activity also had lower mortality rates compared to those who cared for hospitalized patients less frequently.¹⁹ An association between higher physician caseloads and better outcomes has been established for many surgical and medical conditions.^30-32 Given that 85% of hospitalists in our program have post-graduate medical training in family medicine (internal department surveys, data not shown), it is less likely that training background can explain differences in outcomes. Instead, differences in patient volumes and the dedicated focus of hospitalists on acute care are likely more important contributors to lower mortality. In our program, a full-time hospitalist spends an average of 2000 hours annually providing services in the hospital setting. The continuous on-site presence of hospitalists enhances their clinical experience with regards to the management of common medical conditions, and increases their exposure to less common presentations of illnesses. The ability to respond to deteriorating patients in a timely manner may be another factor in explaining the differences in mortality rates between dedicated hospital-based generalist providers and similarly trained physicians with a primarily community-based focus.

In our study, hospitalist care was also broadly associated with lower mortality compared to the IM providers, although these differences were not consistently present when patients with specific diagnoses were compared. This may be partly explained by the relationship between caseload and outcomes, but other factors may also be important. For example, patients admitted by IM providers spend significantly more time in specialized units. They also predominantly present with cardiac conditions, and as such may have higher acuity levels and require more invasive interventions. While this may explain the higher observed mortality, a within-group comparison still suggests higher than expected mortality for IM patients. The HSMR methodology measures actual mortality rates compared to what would be expected based on clinical presentation and baseline population characteristics. Calculating HSMR is highly dependent on proper documentation and chart abstraction,^33,34 and it is possible that some of the differences observed are due to incomplete physician documentation. However, a more in-depth analysis of care processes will be required to clarify the observed trends.

Compared to hospitalists, patients cared for by FPs also had higher odds of readmission within 30 days, which is consistent with prior studies.^18,19 One of the criticisms of the hospitalist model has been the inherent discontinuity of care that is built into the model, which can contribute to suboptimal transitions of care between the acute and community settings.³⁵ The expectation is that FPs who admit their own patients do not face this challenge, and as a result their patients should be readmitted less frequently after discharge. Our data and those from previous studies do not support this hypothesis. At the same time, when we studied patients with specific clinical diagnoses, only those hospitalized for pneumonias continued to demonstrate higher readmission odds. This suggests that hospital readmission rate is a complex measure that may be influenced by a multitude of hospital and community factors, and may be different for patients who present with different clinical diagnoses. Further research is required to better understand the relationship between provider type and experience with hospital readmission for patients with various clinical presentations.

Unlike the United States, where hospitalist care has been associated with reductions in LOS,^26,36 studies in the Canadian health care setting have shown mixed results.^17-21 In our evaluation, hospitalist care is not associated with reductions in total LOS compared to care provided by FPs or IM physicians. This could be due to a number of factors. First, unlike FPs, who know their patients, hospitalists may have a more conservative risk tolerance in discharging patients with whom they are not familiar. Similarly, physicians who have trained in IM may have a lower threshold for discharging patients than hospitalists, whose training background is mainly rooted in family medicine.³ Second, discontinuity of care has been associated with longer LOS for hospitalized patients.^37,38 Hospitalists generally work for 7- to 10-day rotations. As a result, a patient may see a number of different hospitalists during the same hospital stay, which could nullify any gains in LOS that may be expected from better familiarity with hospital processes. Third, whereas a FP or an internist may only have a few inpatients under their care at any given time, each hospitalist typically cares for 17 to 22 patients every day. Increasing hospitalist workload has been shown to negatively impact LOS and may result in lower efficiency.³⁹ Finally, many patients in our health system who require more time to recuperate or need complex discharge planning are usually transferred to the care of the hospitalist service from other services, or are preferentially admitted to hospitalists from the emergency department. As a result, hospitalists may look after a disproportionately higher number of long-stay patients. Despite all this, hospitalists in our population perform similarly to FPs, regardless of the clinical diagnoses of hospitalized patients.

Finally, we included only patients admitted to facilities in which a hospitalist service existed during the study period. As a result, a medium-size community hospital without a hospitalist service where patients are cared for exclusively by FPs and IM physicians was not included in the comparisons, and in 4 of the 10 facilities included, the number of FP patients was less than 10% of total hospitalized patients at the site (Appendix A). This may have resulted in an under-representation of FP patients.

Conclusion

Debates about the merits of the hospitalist model in Canada continue, and are in part fueled by a paucity of robust evidence about its impact on care outcomes compared to more traditional ways of providing inpatient care. In our evaluation, care provided by hospitalists is associated with lower mortality and readmission rates, despite similar LOS compared with FPs. Hospitalist care is also associated with lower mortality compared to IM providers. Hospitalists also demonstrated progressive improvement over time, with decreasing LOS and mortality rates and a stable readmission rate. Our results suggest that physicians with a focus on inpatient care can have positive contributions to quality and efficiency of care in Canada.

Compared to patients admitted to hospitalists, patients admitted to other providers had higher odds of mortality (odds ratio [OR] for FP, 1.29; 95% confidence interval [CI], 1.21-1.37; OR for IM, 1.24; 95% CI, 1.15-1.33). Compared to hospitalist care, FP care was associated with higher readmission (OR, 1.27; 95% CI, 1.22-1.33), while IM care showed lower odds of readmission (OR, 0.83; 95% CI, 0.79-0.87). Patients admitted to the IM group had significantly lower total LOS (mean, 5.13 days; 95% CI, 5.04-5.21) compared to patients admitted to hospitalists (mean, 7.37 days; CI, 7.26-7.49) and FPs (mean, 7.30 days; 95% CI, 7.19-7.41). In a subgroup analysis of patients presenting with congestive heart failure, chronic obstructive pulmonary disease, and pneumonia, these general tendencies broadly persisted for mortality and LOS comparisons between FPs and hospitalists, but results were mixed for hospital readmissions.
• Conclusion: Care provided by hospitalists was associated with lower mortality and readmission rates compared with care provided by FPs, despite similar LOS. These findings may reflect differences in volume of services delivered by individual physicians, on-site availability to address urgent medical issues, and evolving specialization of clinical and nonclinical care processes in the acute care setting.

The hospitalist model of care has undergone rapid growth globally in recent years.¹ The first hospitalist programs in Canada began around the same time as those in the United States and share many similarities in design and operations with their counterparts.^2-4 However, unlike in the United States, where the hospitalist model has successfully established itself as an emerging specialty, debates about the merits of the model and its value proposition continue among Canadian observers.^5-9

Historically, the type of physicians who acted as the most responsible provider (MRP) in Canadian hospitals depended on setting and geography.¹⁰ In large urban areas, groups of general internists or specialists have historically looked after general medicine patients as part of university-affiliated teaching services.^11,12 Patients admitted to community hospitals have traditionally been cared for by their own primary care providers, typically general practitioners or family physicians (FPs). In the mid-1990s, many primary care providers in urban centers began to withdraw from inpatient care and primarily focused their practices in the outpatient setting.^13-15 Hospitalist programs emerged as health care administrators sought to fill the resulting gap in MRP coverage.^2,10

To date, attempts to understand the impact of hospitalist programs in Canada have been limited. A number of early studies aimed to describe¹⁶ the role of hospitalists in Canada and suggested improvements in length of stay (LOS) and staff satisfaction.¹⁷ However, these studies relied on unadjusted before-after comparisons and lacked methodological rigor to draw robust conclusions. More recently, a few studies have evaluated care outcomes associated with hospitalists using administrative databases, which attempted to control for potential confounding factors.^18-21

While these studies are beginning to shed some light on the impact of hospital medicine programs in Canada, there are a number of issues that limit their generalizability. For example, the majority of studies to date focus on hospital medicine programs in Canada’s largest province (Ontario), and most describe experiences from single institutions. Since each of the 13 provincial and territorial governments organizes its health care system differently,²² results from 1 province may not be generalizable to other parts of the country. Moreover, hospitalists in Ontario are more diverse in their training backgrounds, with a larger percentage having trained in general internal medicine (IM), as compared to other parts of Canada, where the majority of hospitalists are overwhelmingly trained as FPs.³

We aimed to study care outcomes associated with a network of hospitalist services compared to “traditional” providers (community-based FPs and IM specialists) in a large integrated health care system in the province of British Columbia in western Canada. The hospital medicine services in this network span a range of community and academic hospitals, and collectively constitute 1 of the largest regional programs in the country. This provides a unique opportunity to understand the impact of hospitalists on outcome measures across a range of acute care institutions.

Setting and Population

Fraser Health Authority is 1 of 5 regional health authorities in British Columbia that emerged in 2001.^23,24 It operates a network of hospitalist programs in 10 of its 12 acute care hospitals. In addition to hospitalists, there are a variable number of “traditional” physician providers who continue to act as MRPs. These include community-based FPs who continue to see their own patients in the hospital, either as part of a solo-practice model or a clinic-based call group. There are also a number of general internists and other subspecialists who accept MRP roles for general medicine patients who may present with higher-acuity conditions. As a result, patients requiring hospitalization due to nonsurgical or noncritical care conditions at each Fraser Health hospital may be cared for by a physician belonging to 1 of 3 groups, depending on local circumstances: an FP, a hospitalist, or an internist.

Inclusion and Exclusion Criteria

In order to evaluate comparative outcomes associated with hospitalist care, we included all patients admitted to a physician in each of the 3 provider groups between April 1, 2012, and March 31, 2018. We chose this time period for 2 reasons: first, we wanted to ensure comparability over an extended period of time, given the methodological changes implemented in 2009 by the Canadian Institute for Health Information (CIHI), the federal organization in the country responsible for setting standards for health care measures.²⁵ Second, previous internal reviews had suggested that data quality prior to this year was inconsistent. We only considered hospitalizations where patients were admitted to and discharged by the same service, and excluded 2 acute care facilities and 1 free-standing rehabilitation facility without a hospitalist service during this period. We also excluded patients who resided in a location beyond the geographic catchment area of Fraser Health. Further details about data collection are outlined in the Appendix.

Measures

We used the framework developed by White and Glazier²⁶ to inform the selection of our outcome measures, as well as relevant variables that may impact them. This framework proposes that the design of the inpatient care model (structures and processes of care) directly affects care outcomes. The model also proposes that patient and provider attributes can modulate this relationship, and suggests that a comprehensive evaluation of hospitalist performance needs to take these factors into account. We identified average total LOS, 30-day readmission rate, in-hospital mortality, and hospital standardized mortality ratio (HSMR)²⁷ as primary outcome measures. HSMR is defined as actual over expected mortality and is measured by CIHI through a formula that takes into account patient illness attributes (eg, the most responsible diagnosis, comorbidity levels) and baseline population mortality rates.²⁷ We chose these measures because they are clinically relevant and easy to obtain and have been utilized in previous similar studies in Canada and the United States.^18-21,26

Statistical Analysis

Baseline demographic and clinical differences in patient outcomes were examined using independent t-tests or chi-square tests. Furthermore, baseline differences based on provider groups were explored using analysis of variance or chi-square tests. Multiple logistic regression analyses were completed to determine the relationship between provider groups and readmission and mortality, while the relationship between provider groups and hospital LOS was determined with generalized linear regression (using gamma distribution and a log link). Gamma distribution with a log link analysis is appropriate with outcome measures that are positively skewed (eg, hospital LOS). It assumes that data are sampled from an exponential family of distributions, thus mimicking a log-normal distribution, and minimizes estimation bias and standard errors. These analyses were completed while controlling for the effects of age, gender, and other potential confounding factors.

We initially attempted to control for case mix by incorporating case-mix groups (CMGs) in our multivariate analysis. However, we identified 475 CMGs with at least 1 patient in our study population. We then explored the inclusion of major clinical categories (MCCs) that broadly group CMGs into various higher order/organ-system level categories (eg, diseases of the respiratory system); however, we could not aggregate them into sufficiently homogenous groups to be entered into regression models. Instead, we conducted subgroup analyses on patients in our study population who were hospitalized with 1 of the following 3 CMGs: chronic obstructive pulmonary disease (COPD, n = 11,404 patients), congestive heart failure without coronary angiography (CHF, n = 7680), and pneumonia (itself an aggregate of 3 separate CMGs: aspiration pneumonia, bacterial pneumonia, viral/unspecified pneumonia, n = 11,155). We chose these CMGs as they are among the top 8 presentations for all 3 provider groups.

For all outcome measures, we excluded atypical patients (defined by CIHI as those with atypically long stays) and patients who had been transferred between facilities. For the readmission analysis, we also excluded patients who died in the hospital (Appendix A). Data analyses were completed in IBM SPSS, version 21. For all analyses, significance was determined using 2-tailed test and alpha < 0.05.

Ethics

The Fraser Health Department of Research and Evaluation reviewed this project to determine need for formal Ethics Review Board review, and granted an exemption based on institutional guidelines for program evaluations.

Results

A total of 132,178 patients were admitted to and discharged by 1 of the 3 study provider groups during the study period, accounting for a total of 248,412 hospitalizations. After excluding patients cared for in Fraser Health facilities without a hospitalist service and those who resided in a geographic area beyond Fraser Health, a total of 224,214 admissions were included in the final analysis.

Patient Characteristics

The demographic and clinical characteristics of patients by provider group are summarized in Table 1. Patients admitted to IM providers were substantially younger than those admitted to either FPs or hospitalists (61.00 vs 70.86 and 71.22 years, respectively; P < 0.005). However, patients admitted to hospitalists had higher degrees of complexity (as measured by higher comorbidity levels, number of secondary diagnoses, and higher resource intensity weights [RIWs]; P < 000.1 for all comparisons). Overall, the most common CMGs seen by FPs and hospitalists were similar, while IM providers primarily saw patients with cardiac conditions (Table 2).

Trends Over Time

During the study period, the number of patients admitted to the hospitalist services increased by 24%, while admissions to FPs and IM providers declined steadily (Figure). During this time, LOS for hospitalists progressively declined, while LOS for FPs and IM providers increased. Similar trends were observed for measures of mortality, while readmission rates remained constant for FPs, despite a decline observed for other providers.

Table 3 summarizes the relationship between provider groups and in-hospital mortality (n = 183,779). Controlling for other variables, patients admitted to FP and IM providers had higher odds of mortality when compared to hospitalists (odds ratio [OR] for FPs, 1.29; 95% confidence interval [CI], 1.21-1.37; OR for IM, 1.24; 95% CI, 1.15-1.33). Older age, higher comorbidity level, higher number of secondary diagnoses, higher use of hospital resources (as measured by RIWs), longer than expected hospital stay (as measured by conservable days), and male gender were also associated with higher mortality. Similarly, patients receiving palliative care and those who spent at least 1 day in a special care unit (critical care, observation, and monitored care units) also had higher odds of mortality. On the other hand, admission to nonteaching medium facilities and longer hospital stay were associated with lower mortality. Compared to the first year of this analysis, lower mortality rates were observed in subsequent fiscal years. Finally, there appear to be geographic variations in mortality within Fraser Health.

Our analysis of patients with COPD, CHF, and pneumonia showed mixed results (Table 4). Patients admitted to the FP provider group with CHF and pneumonia had higher mortality compared to hospitalists (OR for CHF, 1.77; 95% CI, 1.38-2.27; OR for pneumonia, 1.53; 95% CI, 1.25-1.88), with a similar but nonstatistically significant trend observed for patients with COPD (OR, 1.29; 95% CI, 0.99-1.70). On the other hand, the higher observed mortality associated with the IM provider group in the overall study population only persisted for patients with COPD (OR, 2.71; 95% CI, 1.94-3.80), with no statistically significant differences for patients with CHF (OR, 1.18; 95% CI, 0.84-1.65) and pneumonia (OR, 0.93; 95% CI, 0.69-1.25).

We also studied adjusted mortality as measured by HSMRs. Currently, our Health Information Management system calculates an HSMR value for each patient admitted to our acute care facilities using the methodology developed by CIHI. Prior internal audits demonstrated that our internal calculations closely approximate those reported nationally. Our analysis suggests that over time, HSMR rates for the 3 provider groups have diverged, with patients admitted to IM providers having a higher mortality rate than what would be expected based on the presenting clinical conditions and comorbidity levels (Figure, part D).

Readmission

The results of our multiple logistic regression for readmission are summarized in Table 5 (n = 166,042). The impact of provider group on 30-day readmission is mixed, with higher odds associated with FPs compared to hospitalists (OR, 1.27; 95% CI, 1.22-1.34) and lower odds associated with IM physicians (OR, 0.83; 95% CI, 0.79-0.87). Gender and RIW did not show any significant associations, but increasing age, higher number of secondary diagnoses, higher comorbidity levels, and longer than expected LOS (as measure by conservable days) were associated with higher odds of readmission. Conversely, longer hospitalization, admission to a large community hospital, palliative status, admission to a special care unit, geography, and fiscal year were associated with lower odds of readmission.

The above differences between provider groups were no longer consistently present when we analyzed patients presenting with COPD, CHF, and pneumonias (Table 6). Only patients admitted to the FP provider group with pneumonia had higher odds of readmission compared to hospitalists (OR, 1.27; 95% CI, 1.05-1.54). Conversely, only patients admitted to the IM provider group with CHF showed lower readmission (OR, 0.75; 95% CI, 0.62-0.92).

Results using generalized linear regressions for total LOS are presented in Table 7 (n = 183,779). Patients admitted to the IM provider group had significantly lower total LOS (mean, 5.13 days; 95% CI, 5.04-5.21) compared to the hospitalist (mean, 7.37 days; 95% CI, 7.26-7.49) and FP (mean, 7.30 days; 95% CI, 7.19-7.41) groups, with no significant differences between the latter 2 groups. Older patients, females, patients with higher comorbidity levels or number of secondary diagnoses, higher RIW, palliative patients, and discharge to a facility other than the patient’s home were associated with a significantly longer LOS. On the other hand, admission to nonteaching hospitals and admission to a special care unit was associated with lower LOS.

When we compared total LOS for patients admitted with COPD, CHF, and pneumonias, the same differences observed for the broader comparisons persisted: IM patients consistently showed shorter LOS compared to hospitalist patients, while LOS associated with FP patients was similar (Table 8).

Discussion

To our knowledge, our evaluation is the largest study to date designed to understand outcomes associated with hospitalist care in Canada. Our analyses suggest that patients admitted to our large network of hospitalist services present with clinical conditions that are very similar to those of general medicine patients in other Canadian provinces.^28,29 They also show that patients cared for by hospitalists experience lower mortality rates compared to those cared for by FPs. Our findings are similar to previous studies, which have suggested a 12% to 75% reduction in odds of mortality associated with hospitalist care.^18,19 These differences persisted even when we focused on patients presenting with specific clinical conditions (CHF, COPD, and pneumonias).

White and colleagues have previously demonstrated that generalist physicians who had higher volumes of inpatient care activity also had lower mortality rates compared to those who cared for hospitalized patients less frequently.¹⁹ An association between higher physician caseloads and better outcomes has been established for many surgical and medical conditions.^30-32 Given that 85% of hospitalists in our program have post-graduate medical training in family medicine (internal department surveys, data not shown), it is less likely that training background can explain differences in outcomes. Instead, differences in patient volumes and the dedicated focus of hospitalists on acute care are likely more important contributors to lower mortality. In our program, a full-time hospitalist spends an average of 2000 hours annually providing services in the hospital setting. The continuous on-site presence of hospitalists enhances their clinical experience with regards to the management of common medical conditions, and increases their exposure to less common presentations of illnesses. The ability to respond to deteriorating patients in a timely manner may be another factor in explaining the differences in mortality rates between dedicated hospital-based generalist providers and similarly trained physicians with a primarily community-based focus.

In our study, hospitalist care was also broadly associated with lower mortality compared to the IM providers, although these differences were not consistently present when patients with specific diagnoses were compared. This may be partly explained by the relationship between caseload and outcomes, but other factors may also be important. For example, patients admitted by IM providers spend significantly more time in specialized units. They also predominantly present with cardiac conditions, and as such may have higher acuity levels and require more invasive interventions. While this may explain the higher observed mortality, a within-group comparison still suggests higher than expected mortality for IM patients. The HSMR methodology measures actual mortality rates compared to what would be expected based on clinical presentation and baseline population characteristics. Calculating HSMR is highly dependent on proper documentation and chart abstraction,^33,34 and it is possible that some of the differences observed are due to incomplete physician documentation. However, a more in-depth analysis of care processes will be required to clarify the observed trends.

Compared to hospitalists, patients cared for by FPs also had higher odds of readmission within 30 days, which is consistent with prior studies.^18,19 One of the criticisms of the hospitalist model has been the inherent discontinuity of care that is built into the model, which can contribute to suboptimal transitions of care between the acute and community settings.³⁵ The expectation is that FPs who admit their own patients do not face this challenge, and as a result their patients should be readmitted less frequently after discharge. Our data and those from previous studies do not support this hypothesis. At the same time, when we studied patients with specific clinical diagnoses, only those hospitalized for pneumonias continued to demonstrate higher readmission odds. This suggests that hospital readmission rate is a complex measure that may be influenced by a multitude of hospital and community factors, and may be different for patients who present with different clinical diagnoses. Further research is required to better understand the relationship between provider type and experience with hospital readmission for patients with various clinical presentations.

Unlike the United States, where hospitalist care has been associated with reductions in LOS,^26,36 studies in the Canadian health care setting have shown mixed results.^17-21 In our evaluation, hospitalist care is not associated with reductions in total LOS compared to care provided by FPs or IM physicians. This could be due to a number of factors. First, unlike FPs, who know their patients, hospitalists may have a more conservative risk tolerance in discharging patients with whom they are not familiar. Similarly, physicians who have trained in IM may have a lower threshold for discharging patients than hospitalists, whose training background is mainly rooted in family medicine.³ Second, discontinuity of care has been associated with longer LOS for hospitalized patients.^37,38 Hospitalists generally work for 7- to 10-day rotations. As a result, a patient may see a number of different hospitalists during the same hospital stay, which could nullify any gains in LOS that may be expected from better familiarity with hospital processes. Third, whereas a FP or an internist may only have a few inpatients under their care at any given time, each hospitalist typically cares for 17 to 22 patients every day. Increasing hospitalist workload has been shown to negatively impact LOS and may result in lower efficiency.³⁹ Finally, many patients in our health system who require more time to recuperate or need complex discharge planning are usually transferred to the care of the hospitalist service from other services, or are preferentially admitted to hospitalists from the emergency department. As a result, hospitalists may look after a disproportionately higher number of long-stay patients. Despite all this, hospitalists in our population perform similarly to FPs, regardless of the clinical diagnoses of hospitalized patients.

Finally, we included only patients admitted to facilities in which a hospitalist service existed during the study period. As a result, a medium-size community hospital without a hospitalist service where patients are cared for exclusively by FPs and IM physicians was not included in the comparisons, and in 4 of the 10 facilities included, the number of FP patients was less than 10% of total hospitalized patients at the site (Appendix A). This may have resulted in an under-representation of FP patients.

Conclusion

Debates about the merits of the hospitalist model in Canada continue, and are in part fueled by a paucity of robust evidence about its impact on care outcomes compared to more traditional ways of providing inpatient care. In our evaluation, care provided by hospitalists is associated with lower mortality and readmission rates, despite similar LOS compared with FPs. Hospitalist care is also associated with lower mortality compared to IM providers. Hospitalists also demonstrated progressive improvement over time, with decreasing LOS and mortality rates and a stable readmission rate. Our results suggest that physicians with a focus on inpatient care can have positive contributions to quality and efficiency of care in Canada.

Abstract

• Objective: To study care outcomes associated with a network of hospitalist services compared to traditional providers.
• Design: Retrospective review of administrative data.
• Setting and participants: Patients from a large integrated health care system in British Columbia in western Canada admitted and cared for by 3 provider groups between April 1, 2012, and March 31, 2018: hospitalists, family physicians (FP), and internal medicine (IM) physicians:
• Measurements: Average total length of stay (LOS), 30-day readmission, in-hospital mortality, and hospital standardized mortality ratio (HSMR) were the study outcome measures. Multiple logistic regression or generalized regression were completed to determine the relationship between provider groups and outcomes.
• Results: A total of 248,412 hospitalizations were included. Compared to patients admitted to hospitalists, patients admitted to other providers had higher odds of mortality (odds ratio [OR] for FP, 1.29; 95% confidence interval [CI], 1.21-1.37; OR for IM, 1.24; 95% CI, 1.15-1.33). Compared to hospitalist care, FP care was associated with higher readmission (OR, 1.27; 95% CI, 1.22-1.33), while IM care showed lower odds of readmission (OR, 0.83; 95% CI, 0.79-0.87). Patients admitted to the IM group had significantly lower total LOS (mean, 5.13 days; 95% CI, 5.04-5.21) compared to patients admitted to hospitalists (mean, 7.37 days; CI, 7.26-7.49) and FPs (mean, 7.30 days; 95% CI, 7.19-7.41). In a subgroup analysis of patients presenting with congestive heart failure, chronic obstructive pulmonary disease, and pneumonia, these general tendencies broadly persisted for mortality and LOS comparisons between FPs and hospitalists, but results were mixed for hospital readmissions.
• Conclusion: Care provided by hospitalists was associated with lower mortality and readmission rates compared with care provided by FPs, despite similar LOS. These findings may reflect differences in volume of services delivered by individual physicians, on-site availability to address urgent medical issues, and evolving specialization of clinical and nonclinical care processes in the acute care setting.

Results

A total of 132,178 patients were admitted to and discharged by 1 of the 3 study provider groups during the study period, accounting for a total of 248,412 hospitalizations. After excluding patients cared for in Fraser Health facilities without a hospitalist service and those who resided in a geographic area beyond Fraser Health, a total of 224,214 admissions were included in the final analysis.

Patient Characteristics

The demographic and clinical characteristics of patients by provider group are summarized in Table 1. Patients admitted to IM providers were substantially younger than those admitted to either FPs or hospitalists (61.00 vs 70.86 and 71.22 years, respectively; P < 0.005).

During the study period, the number of patients admitted to the hospitalist services increased by 24%, while admissions to FPs and IM providers declined steadily (Figure). During this time, LOS for hospitalists progressively declined, while LOS for FPs and IM providers increased. Similar trends were observed for measures of mortality, while readmission rates remained constant for FPs, despite a decline observed for other providers.

Table 3 summarizes the relationship between provider groups and in-hospital mortality (n = 183,779). Controlling for other variables, patients admitted to FP and IM providers had higher odds of mortality when compared to hospitalists (odds ratio [OR] for FPs, 1.29; 95% confidence interval [CI], 1.21-1.37; OR for IM, 1.24; 95% CI, 1.15-1.33). Older age, higher comorbidity level, higher number of secondary diagnoses, higher use of hospital resources (as measured by RIWs), longer than expected hospital stay (as measured by conservable days), and male gender were also associated with higher mortality. Similarly, patients receiving palliative care and those who spent at least 1 day in a special care unit (critical care, observation, and monitored care units) also had higher odds of mortality. On the other hand, admission to nonteaching medium facilities and longer hospital stay were associated with lower mortality. Compared to the first year of this analysis, lower mortality rates were observed in subsequent fiscal years. Finally, there appear to be geographic variations in mortality within Fraser Health.

Our analysis of patients with COPD, CHF, and pneumonia showed mixed results (Table 4). Patients admitted to the FP provider group with CHF and pneumonia had higher mortality compared to hospitalists (OR for CHF, 1.77; 95% CI, 1.38-2.27; OR for pneumonia, 1.53; 95% CI, 1.25-1.88), with a similar but nonstatistically significant trend observed for patients with COPD (OR, 1.29; 95% CI, 0.99-1.70). On the other hand, the higher observed mortality associated with the IM provider group in the overall study population only persisted for patients with COPD (OR, 2.71; 95% CI, 1.94-3.80), with no statistically significant differences for patients with CHF (OR, 1.18; 95% CI, 0.84-1.65) and pneumonia (OR, 0.93; 95% CI, 0.69-1.25).

We also studied adjusted mortality as measured by HSMRs. Currently, our Health Information Management system calculates an HSMR value for each patient admitted to our acute care facilities using the methodology developed by CIHI. Prior internal audits demonstrated that our internal calculations closely approximate those reported nationally. Our analysis suggests that over time, HSMR rates for the 3 provider groups have diverged, with patients admitted to IM providers having a higher mortality rate than what would be expected based on the presenting clinical conditions and comorbidity levels (Figure, part D).

Readmission

The results of our multiple logistic regression for readmission are summarized in Table 5 (n = 166,042). The impact of provider group on 30-day readmission is mixed, with higher odds associated with FPs compared to hospitalists (OR, 1.27; 95% CI, 1.22-1.34) and lower odds associated with IM physicians (OR, 0.83; 95% CI, 0.79-0.87). Gender and RIW did not show any significant associations, but increasing age, higher number of secondary diagnoses, higher comorbidity levels, and longer than expected LOS (as measure by conservable days) were associated with higher odds of readmission. Conversely, longer hospitalization, admission to a large community hospital, palliative status, admission to a special care unit, geography, and fiscal year were associated with lower odds of readmission.

The above differences between provider groups were no longer consistently present when we analyzed patients presenting with COPD, CHF, and pneumonias (Table 6). Only patients admitted to the FP provider group with pneumonia had higher odds of readmission compared to hospitalists (OR, 1.27; 95% CI, 1.05-1.54). Conversely, only patients admitted to the IM provider group with CHF showed lower readmission (OR, 0.75; 95% CI, 0.62-0.92).

Results using generalized linear regressions for total LOS are presented in Table 7 (n = 183,779). Patients admitted to the IM provider group had significantly lower total LOS (mean, 5.13 days; 95% CI, 5.04-5.21) compared to the hospitalist (mean, 7.37 days; 95% CI, 7.26-7.49) and FP (mean, 7.30 days; 95% CI, 7.19-7.41) groups, with no significant differences between the latter 2 groups. Older patients, females, patients with higher comorbidity levels or number of secondary diagnoses, higher RIW, palliative patients, and discharge to a facility other than the patient’s home were associated with a significantly longer LOS. On the other hand, admission to nonteaching hospitals and admission to a special care unit was associated with lower LOS.

When we compared total LOS for patients admitted with COPD, CHF, and pneumonias, the same differences observed for the broader comparisons persisted: IM patients consistently showed shorter LOS compared to hospitalist patients, while LOS associated with FP patients was similar (Table 8).

Discussion

To our knowledge, our evaluation is the largest study to date designed to understand outcomes associated with hospitalist care in Canada. Our analyses suggest that patients admitted to our large network of hospitalist services present with clinical conditions that are very similar to those of general medicine patients in other Canadian provinces.^28,29 They also show that patients cared for by hospitalists experience lower mortality rates compared to those cared for by FPs. Our findings are similar to previous studies, which have suggested a 12% to 75% reduction in odds of mortality associated with hospitalist care.^18,19 These differences persisted even when we focused on patients presenting with specific clinical conditions (CHF, COPD, and pneumonias).

White and colleagues have previously demonstrated that generalist physicians who had higher volumes of inpatient care activity also had lower mortality rates compared to those who cared for hospitalized patients less frequently.¹⁹ An association between higher physician caseloads and better outcomes has been established for many surgical and medical conditions.^30-32 Given that 85% of hospitalists in our program have post-graduate medical training in family medicine (internal department surveys, data not shown), it is less likely that training background can explain differences in outcomes. Instead, differences in patient volumes and the dedicated focus of hospitalists on acute care are likely more important contributors to lower mortality. In our program, a full-time hospitalist spends an average of 2000 hours annually providing services in the hospital setting. The continuous on-site presence of hospitalists enhances their clinical experience with regards to the management of common medical conditions, and increases their exposure to less common presentations of illnesses. The ability to respond to deteriorating patients in a timely manner may be another factor in explaining the differences in mortality rates between dedicated hospital-based generalist providers and similarly trained physicians with a primarily community-based focus.

In our study, hospitalist care was also broadly associated with lower mortality compared to the IM providers, although these differences were not consistently present when patients with specific diagnoses were compared. This may be partly explained by the relationship between caseload and outcomes, but other factors may also be important. For example, patients admitted by IM providers spend significantly more time in specialized units. They also predominantly present with cardiac conditions, and as such may have higher acuity levels and require more invasive interventions. While this may explain the higher observed mortality, a within-group comparison still suggests higher than expected mortality for IM patients. The HSMR methodology measures actual mortality rates compared to what would be expected based on clinical presentation and baseline population characteristics. Calculating HSMR is highly dependent on proper documentation and chart abstraction,^33,34 and it is possible that some of the differences observed are due to incomplete physician documentation. However, a more in-depth analysis of care processes will be required to clarify the observed trends.

Compared to hospitalists, patients cared for by FPs also had higher odds of readmission within 30 days, which is consistent with prior studies.^18,19 One of the criticisms of the hospitalist model has been the inherent discontinuity of care that is built into the model, which can contribute to suboptimal transitions of care between the acute and community settings.³⁵ The expectation is that FPs who admit their own patients do not face this challenge, and as a result their patients should be readmitted less frequently after discharge. Our data and those from previous studies do not support this hypothesis. At the same time, when we studied patients with specific clinical diagnoses, only those hospitalized for pneumonias continued to demonstrate higher readmission odds. This suggests that hospital readmission rate is a complex measure that may be influenced by a multitude of hospital and community factors, and may be different for patients who present with different clinical diagnoses. Further research is required to better understand the relationship between provider type and experience with hospital readmission for patients with various clinical presentations.

Unlike the United States, where hospitalist care has been associated with reductions in LOS,^26,36 studies in the Canadian health care setting have shown mixed results.^17-21 In our evaluation, hospitalist care is not associated with reductions in total LOS compared to care provided by FPs or IM physicians. This could be due to a number of factors. First, unlike FPs, who know their patients, hospitalists may have a more conservative risk tolerance in discharging patients with whom they are not familiar. Similarly, physicians who have trained in IM may have a lower threshold for discharging patients than hospitalists, whose training background is mainly rooted in family medicine.³ Second, discontinuity of care has been associated with longer LOS for hospitalized patients.^37,38 Hospitalists generally work for 7- to 10-day rotations. As a result, a patient may see a number of different hospitalists during the same hospital stay, which could nullify any gains in LOS that may be expected from better familiarity with hospital processes. Third, whereas a FP or an internist may only have a few inpatients under their care at any given time, each hospitalist typically cares for 17 to 22 patients every day. Increasing hospitalist workload has been shown to negatively impact LOS and may result in lower efficiency.³⁹ Finally, many patients in our health system who require more time to recuperate or need complex discharge planning are usually transferred to the care of the hospitalist service from other services, or are preferentially admitted to hospitalists from the emergency department. As a result, hospitalists may look after a disproportionately higher number of long-stay patients. Despite all this, hospitalists in our population perform similarly to FPs, regardless of the clinical diagnoses of hospitalized patients.

Finally, we included only patients admitted to facilities in which a hospitalist service existed during the study period. As a result, a medium-size community hospital without a hospitalist service where patients are cared for exclusively by FPs and IM physicians was not included in the comparisons, and in 4 of the 10 facilities included, the number of FP patients was less than 10% of total hospitalized patients at the site (Appendix A). This may have resulted in an under-representation of FP patients.

Conclusion

Debates about the merits of the hospitalist model in Canada continue, and are in part fueled by a paucity of robust evidence about its impact on care outcomes compared to more traditional ways of providing inpatient care. In our evaluation, care provided by hospitalists is associated with lower mortality and readmission rates, despite similar LOS compared with FPs. Hospitalist care is also associated with lower mortality compared to IM providers. Hospitalists also demonstrated progressive improvement over time, with decreasing LOS and mortality rates and a stable readmission rate. Our results suggest that physicians with a focus on inpatient care can have positive contributions to quality and efficiency of care in Canada.
