There’s a new morning ritual in Pinedale, Wyoming, a town of about 2000, nestled against the Wind River Mountains.

Friends and neighbors in the oil- and gas-rich community “take their morning coffee and pull up” to watch workers building the county’s first hospital, said Kari DeWitt, the project’s public relations director.

“I think it’s just gratitude,” Ms. DeWitt said.

Sublette County is the only one in Wyoming — where counties span thousands of square miles — without a hospital. The 10-bed, 40,000-square-foot hospital, with a similarly sized attached long-term care facility, is slated to open by the summer of 2025.

Ms. DeWitt, who also is executive director of the Sublette County Health Foundation, has an office at the town’s health clinic with a window view of the construction.

Pinedale’s residents have good reason to be excited. New full-service hospitals with inpatient beds are rare in rural America, where declining population has spurred decades of downsizing and closures. Yet, a few communities in Wyoming and others in Kansas and Georgia are defying the trend.

“To be honest with you, it even seems strange to me,” said Wyoming Hospital Association President Eric Boley. Small rural “hospitals are really struggling all across the country,” he said.

There is no official tally of new hospitals being built in rural America, but industry experts such as Mr. Boley said they’re rare. Typically, health-related construction projects in rural areas are for smaller urgent care centers or stand-alone emergency facilities or are replacements for old hospitals.

About half of rural hospitals lost money in the prior year, according to Chartis, a health analytics and consulting firm. And nearly 150 rural hospitals have closed or converted to smaller operations since 2010, according to data collected by the University of North Carolina’s Cecil G. Sheps Center for Health Services Research.

To stem the tide of closures, Congress created a new rural emergency hospital designation that allowed struggling hospitals to close their inpatient units and provide only outpatient and emergency services. Since January 2023, when the program took effect, 32 of the more than 1700 eligible rural hospitals — from Georgia to New Mexico — have joined the program, according to data from the Centers for Medicare & Medicaid Services.

Tony Breitlow is healthcare studio director for EUA, which has extensive experience working for rural health care systems. Mr. Breitlow said his national architecture and engineering firm’s work expands, replaces, or revamps older buildings, many of which were constructed during the middle of the last century.

The work, Mr. Breitlow said, is part of health care “systems figuring out how to remain robust and viable.”

Freeman Health System, based in Joplin, Missouri, announced plans last year to build a new 50-bed hospital across the state line in Kansas. Paula Baker, Freeman’s president and chief executive, said the system is building for patients in the southeastern corner of the state who travel 45 minutes or more to its bigger Joplin facilities for care.

Freeman’s new hospital, with construction on the building expected to begin in the spring, will be less than 10 miles away from an older, 64-bed hospital that has existed for decades. Kansas is one of more than a dozen states with no “certificate of need” law that would require health providers to obtain approval from the state before offering new services or building or expanding facilities.

Ms. Baker also said Freeman plans to operate emergency services and a small 10-bed outpost in Fort Scott, Kansas, opening early next year in a corner of a hospital that closed in late 2018. Residents there “cried, they cheered, they hugged me,” Ms. Baker said, adding that the “level of appreciation and gratitude that they felt and they displayed was overwhelming to me.”

Michael Topchik, executive director of the Chartis Center for Rural Health, said regional healthcare systems in the Upper Midwest have been particularly active in competing for patients by, among other things, building new hospitals.

And while private corporate money can drive construction, many rural hospital projects tap government programs, especially those supported by the US Department of Agriculture, Mr. Topchik said. That, he said, “surprises a lot of people.”

Since 2021, the USDA’s rural Community Facilities Programs have awarded $2.24 billion in loans and grants to 68 rural hospitals for work that was not related to an emergency or disaster, according to data analyzed by KFF Health News and confirmed by the agency. The federal program is funded through what is often known as the farm bill, which faces a September congressional renewal deadline.

Nearly all the projects are replacements or expansions and updates of older facilities.

The USDA confirmed that three new or planned Wyoming hospitals received federal funding. Hospital projects in Riverton and Saratoga received loans of $37.2 million and $18.3 million, respectively. Pinedale’s hospital received a $29.2 million loan from the agency.

Wyoming’s new construction is rare in a state where more than 80% of rural hospitals reported losses in the third quarter of 2023, according to Chartis. The state association’s Mr. Boley said he worries about several hospitals that have less than 10 days’ cash on hand “day and night.”

Pinedale’s project loan was approved after the community submitted a feasibility study to the USDA that included local clinics and a long-term care facility. “It’s pretty remote and right up in the mountains,” Mr. Boley said.

Pinedale’s Ms. DeWitt said the community was missing key services, such as blood transfusions, which are often necessary when there is a trauma like a car crash or if a pregnant woman faces severe complications. Local ambulances drove 94,000 miles last year, she said.

Ms. DeWitt began working to raise support for the new hospital after her own pregnancy-related trauma in 2014. She was bleeding heavily and arrived at the local health clinic believing it operated like a hospital.

“It was shocking to hear, ‘No, we’re not a hospital. We can’t do blood transfusions. We’re just going to have to pray you live for the next 45 minutes,’ ” Ms. DeWitt said.

Ms. DeWitt had to be airlifted to Idaho, where she delivered a few minutes after landing. When the hospital financing went on the ballot in 2020, Ms. DeWitt — fully recovered, with healthy grade-schoolers at home — began making five calls a night to rally support for a county tax increase to help fund the hospital.

“By improving health care, I think we improve everybody’s chances of survival. You know, it’s pretty basic,” Ms. DeWitt said.

A noninvasive eye test could help people with Sjögren disease — a disorder that can go undiagnosed for years — get relief sooner, suggested a pilot study published in Therapeutic Advances in Musculoskeletal Disease.

Researchers led by Jing Wu, Department of Ophthalmology, Tongren Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China, and colleagues used infrared imaging to detect atrophy of the oil-producing meibomian glands, which lubricate the eyelids and eyes, in 56 patients with suspected Sjögren disease. The test can be administered by an eye care practitioner using a Keratograph 5M machine. Patients also underwent salivary gland biopsies to detect Sjögren disease.

A total of 34 patients diagnosed with primary Sjögren disease had more significant atrophy and shortening of the meibomian glands in their upper eyelids than 22 patients with other types of dry eye who served as control patients. The accuracy of temporal and total meibomian gland dysfunction dropout rates in the upper eyelids to predict primary Sjögren disease classification was good, with an area under the curve of 0.94 and 0.91, respectively.

“Sjögren’s-related dry eye is definitely inflammatory,” said Esen Akpek, MD, director of the Ocular Surface Disease and Dry Eye Clinic at Johns Hopkins Medicine, Baltimore, who was not involved with the study. “It starts as inflammation, and then the inflammation spreads to the meibomian glands, to the conjunctiva, cornea, and there will be other findings, like corneal ulcers, corneal melts, cyclitis, retinitis, optic neuritis, uveitis, all these inflammatory diseases of the eye could happen with Sjögren’s.”

With other types of dry eye, such as blepharitis or even meibomian gland dysfunction without Sjögren disease, inflammation is usually confined to the ocular surface, Akpek said. As a result, symptoms tend to be less severe and progressive.

The results of this small study need validation in a larger cohort, said Steven Carsons, MD, chief of the Division of Rheumatology at NYU Langone Hospital–Long Island, who was not involved with the study. In general, however, noninvasive alternatives to today’s tests for Sjögren disease could be useful for patients and physicians.

“The definitive diagnosis is a minor salivary glandular biopsy, which is invasive and isn’t really appealing to a lot of patients,” Dr. Carsons said. This test can also be difficult to access if patients don’t live near a medical center that specializes in Sjögren disease, he said.

“I think it’s everybody’s goal to have a noninvasive test be able, at some point, to replace biopsy,” Dr. Carsons said.

Then there are blood tests. “The other more objective test, the SSA antibodies, are not very specific for Sjögren’s syndrome,” he said. “They’re fairly sensitive, but can also be seen in other autoimmune conditions, particularly lupus.”

With existing tools, however, optometrists and ophthalmologists can do more to diagnose Sjögren disease early, Dr. Akpek said.

“The issue with Sjögren’s is not that there are no earlier diagnostic aids or anything like that,” Dr. Akpek said.

Lissamine green, a dye that stains degraded cells on the eye’s surface, can reveal clues in young adult patients before other signs. “In my opinion, the earliest clinical finding that indicates presence of the disease is lissamine green staining of conjunctiva,” Akpek said.

Meibomian gland imaging would detect the disease at a later point. “By the time you get meibomian gland dysfunction, there has been longer-standing inflammation,” she said.

Two challenges hold back diagnoses, she said. One is that many practitioners mistakenly believe Sjögren disease is just a nuisance even though it can threaten vision through ocular complications and have more far-reaching effects, too.

“There are a lot of extraglandular systemic manifestations of Sjögren’s that cause morbidity in these patients,” Dr. Akpek said. For example, Sjögren disease is associated with lymphoma and other malignancies, interstitial nephritis, autoimmune hepatitis, and interstitial lung disease with fibrosis.

The second challenge, she said, is that many ophthalmologists and optometrists assume rheumatologists will make the Sjögren disease diagnosis first and then refer patients to them. But eye doctors are well positioned to spot the first signs — if they look for them.

“When you complain of dry eye, unless the doctor puts certain dyes and takes a look at the surface with the dye staining, they can’t see that you are dry,” Dr. Akpek said.

Unfortunately, these tests are underutilized. “I’m sorry to say, dry eye testing, like clinical testing, is not very commonly done,” she said. “Dry eye is managed according to patient symptoms. A lot of the time, Sjögren’s patients have such severe dry eye that they don’t complain of dryness anymore because their corneas become numb.”

Another way to prevent diagnostic delay is to collaborate, communicate, and carefully review patient records shared by other specialists.

“Particularly because of the wide involvement of different organ systems, such as the eyes, the mouth with dental problems, and then systemic features, including joints, it really does need the cooperation of ophthalmologists, dental specialists, and rheumatologists — immunologists sometimes — to come together and make this diagnosis,” Dr. Carsons said.

The study was supported by grants from the National Natural Science Foundation of China. The authors had no relevant disclosures.

The second challenge, she said, is that many ophthalmologists and optometrists assume rheumatologists will make the Sjögren disease diagnosis first and then refer patients to them. But eye doctors are well positioned to spot the first signs — if they look for them.

“When you complain of dry eye, unless the doctor puts certain dyes and takes a look at the surface with the dye staining, they can’t see that you are dry,” Dr. Akpek said.

Unfortunately, these tests are underutilized. “I’m sorry to say, dry eye testing, like clinical testing, is not very commonly done,” she said. “Dry eye is managed according to patient symptoms. A lot of the time, Sjögren’s patients have such severe dry eye that they don’t complain of dryness anymore because their corneas become numb.”

Another way to prevent diagnostic delay is to collaborate, communicate, and carefully review patient records shared by other specialists.

“Particularly because of the wide involvement of different organ systems, such as the eyes, the mouth with dental problems, and then systemic features, including joints, it really does need the cooperation of ophthalmologists, dental specialists, and rheumatologists — immunologists sometimes — to come together and make this diagnosis,” Dr. Carsons said.

The study was supported by grants from the National Natural Science Foundation of China. The authors had no relevant disclosures.

TOPLINE:

Emapalumab (Gamifant)-containing regimens stabilize key laboratory parameters and show a high 12-month survival probability in patients with rheumatologic disease–associated hemophagocytic lymphohistiocytosis (HLH).

METHODOLOGY:

• Researchers conducted a retrospective medical chart review study across 33 US hospitals to assess the real-world treatment patterns and outcomes in patients with HLH treated with emapalumab.
• They included 15 patients with rheumatologic disease–associated HLH (median age at diagnosis, 5 years; 73.3% women) who received at least one dose of emapalumab between November 20, 2018, and October 31, 2021.
• Most patients with rheumatologic disease–associated HLH had either systemic juvenile idiopathic arthritis (n = 9) or adult-onset Still’s disease (n = 1).
• Patients received emapalumab for refractory, recurrent, or progressive disease, with an overall treatment duration of 63 days.
• The primary objective of this study was to describe emapalumab treatment patterns such as time to initiation, treatment duration, dosing patterns, and reasons for initiation.

TAKEAWAY:

• Most patients (60%) with rheumatologic disease–associated HLH were critically ill and were initiated on emapalumab in an intensive care unit; emapalumab was mostly initiated for treating refractory (33.3%) and recurrent (33.3%) disease.
• All patients concurrently received emapalumab with other HLH-related therapies, with glucocorticoids (100%) and anakinra (60%) used most frequently.
• Emapalumab treatment led to achievement of normal fibrinogen levels (> 360 mg/dL), according to defined laboratory criteria in all patients with rheumatologic disease–associated HLH, and an 80.6% reduction in the required glucocorticoid dose.
• The 12-month survival probability from the initiation of emapalumab was 86.7% in all patients with rheumatologic disease–associated HLH and 90.0% in the subset with systemic juvenile idiopathic arthritis or adult-onset Still’s disease.

IN PRACTICE:

“In this study, emapalumab-containing regimens normalized rheumatologic disease–associated laboratory parameters, substantially reduced glucocorticoid dose, and were associated with low mortality,” the authors wrote.

The study was led by Shanmuganathan Chandrakasan, MD, Children’s Healthcare of Atlanta, Emory University, Atlanta, Georgia, and was published online on September 8, 2024, in Arthritis & Rheumatology.

LIMITATIONS:

Chart data required for analyses were missing or incomplete in this retrospective study. The sample size of patients with rheumatologic disease–associated HLH was small. No safety data were collected.

DISCLOSURES:

The study was supported by Sobi, which markets emapalumab. Some authors declared receiving grants, consulting fees, or payments or having financial and nonfinancial interests and other ties with several pharmaceutical companies, including Sobi.

TOPLINE:

Older age, male sex, and seropositivity are linked to a higher risk for rheumatoid arthritis–interstitial lung disease (RA-ILD) with a usual interstitial pneumonia (UIP) pattern, while only seropositivity is associated with RA-ILD with a nonspecific interstitial pneumonia pattern (NSIP).

METHODOLOGY:

• Researchers conducted a case-control study using data from two cohorts in the Mass General Brigham Healthcare system to examine the risk factors associated with different subtypes of RA-ILD.
• They identified 208 patients with RA-ILD (mean age at RA diagnosis, 50.7 years; 67.3% women) and 547 control participants with RA but no ILD (mean age at RA diagnosis, 49.1 years; 78.1% women), who had high-resolution computed tomography (HRCT) imaging data available.
• RA-ILD subtypes such as RA-UIP, RA-NSIP, organizing pneumonia, and others were determined with HRCT scans.
• The associations between demographics, lifestyle, and serologic factors and RA-ILD subtypes were evaluated using multivariable logistic regression analysis.

TAKEAWAY:

• The RA-UIP subtype, the one with worst prognosis, was associated with older age during the time of RA diagnosis (odds ratio [OR], 1.03 per year; 95% CI, 1.01-1.05), male sex (OR, 2.15; 95% CI, 1.33-3.48), and seropositivity (OR, 2.08; 95% CI, 1.24-3.48).
• On the other hand, the RA-NSIP subtype was significantly associated only with seropositivity (OR, 3.21; 95% CI, 1.36-7.56).
• Nonfibrotic ILDs were significantly associated with positive smoking status (OR, 2.81; 95% CI, 1.52-5.21) and seropositivity (OR, 2.09; 95% CI, 1.19-3.67).
• The combination of male sex, seropositivity, and positive smoking status was associated with a nearly sevenfold increased risk for RA-UIP (OR, 6.89; 95% CI, 2.41-19.69), compared with having no RA-ILD risk factors.

IN PRACTICE:

“These findings suggest that RA-ILD subtypes may have distinct risk factor profiles and emphasize the importance of further efforts to understand RA-ILD disease heterogeneity to inform screening and prognostication strategies,” the authors wrote.

SOURCE:

The study was led by Gregory C. McDermott, MD, MPH, Brigham and Women’s Hospital, Boston, and was published online on September 11, 2024, in Arthritis Care & Research.

LIMITATIONS:

This study relied on HRCT imaging, which may have introduced selection bias within the control groups. RA disease activity measures were not available for the Mass General Brigham Biobank RA cohort, which limited the analysis of the influence of disease activity on the risk for RA-ILD. Both cohorts predominantly involved White patients, which may have limited the generalizability of the findings to more diverse populations.

Residency programs across the country may have a few more slots for incoming residents due to a recent bump in Medicare funding.

Case in point: The University of Alabama at Birmingham (UAB). The state has one of the top stroke rates in the country, and yet UAB has the only hospital in the state training future doctors to help stroke patients recover. “Our hospital cares for Alabama’s sickest patients, many who need rehabilitation services,” said Craig Hoesley, MD, senior associate dean for medical education, who oversees graduate medical education (GME) or residency programs.

After decades of stagnant support, a recent bump in Medicare funding will allow UAB to add two more physical medicine and rehabilitation residents to the four residencies already receiving such funding.

Medicare also awarded UAB more funding last year to add an addiction medicine fellowship, one of two such training programs in the state for the specialty that helps treat patients fighting addiction.

UAB is among healthcare systems and hospitals nationwide benefiting from a recent hike in Medicare funding for residency programs after some 25 years at the same level of federal support. Medicare is the largest funder of training positions. Otherwise, hospitals finance training through means such as state support.

The latest round of funding, which went into effect in July, adds 200 positions to the doctor pipeline, creating more openings for residents seeking positions after medical school.

In the next few months, the Centers for Medicare & Medicaid Services (CMS) will notify teaching hospitals whether they’ll receive the next round of Medicare funding for more residency positions. At that time, CMS will have awarded nearly half of the 1200 residency training slots Congress approved in the past few years. In 2020 — for the first time since 1996 — Congress approved adding 1000 residency slots at teaching hospitals nationwide. CMS awards the money for 200 slots each year for 5 years.

More than half of the initial round of funding focused on training primary care specialists, with other slots designated for mental health specialists. Last year, Congress also approved a separate allocation of 200 more Medicare-funded residency positions, with at least half designated for psychiatry and related subspecialty residencies to help meet the growing need for more mental health specialists. On August 1, CMS announced it would distribute the funds next year, effective in 2026.

The additional Medicare funding attempts to address the shortage of healthcare providers and ensure future access to care, including in rural and underserved communities. The Association of American Medical Colleges (AAMC) estimates the nation will face a shortage of up to 86,000 physicians by 2036, including primary care doctors and specialists.

In addition, more than 100 million Americans, nearly a third of the nation, don’t have access to primary care due to the physician shortages in their communities, according to the National Association of Community Health Centers.

Major medical organizations, medical schools, and hospital groups have been pushing for years for increased Medicare funding to train new doctors to keep up with the demand for healthcare services and offset the physician shortage. As a cost-saving measure, Medicare set its cap in 1996 for how much it will reimburse each hospital offering GME training. However, according to the medical groups that continue to advocate to Congress for more funding, the funding hasn’t kept pace with the growing healthcare needs or rising medical school enrollment.
 

Adding Residency Spots

In April, Dr. Hoesley of UAB spoke at a Congressional briefing among health systems and hospitals that benefited from the additional funding. He told Congressional leaders how the increased number of GME positions affects UAB Medicine and its ability to care for rural areas.

“We have entire counties in Alabama that don’t have physicians. One way to address the physician shortage is to grow the GME programs. The funding we received will help us grow these programs and care for residents in our state.”

Still, the Medicare funding is only a drop in the bucket, Dr. Hoesley said. “We rely on Medicare funding alongside other funding partners to train residents and expand our care across the state.” He said many UAB residency programs are over their Medicare funding cap and would like to grow, but they can’t without more funding.

Mount Sinai Health System in New York City also will be able to expand its residency program after receiving Medicare support in the latest round of funding. The health system will use the federal funds to train an additional vascular surgeon. Mount Sinai currently receives CMS funding to train three residents in the specialty.

Over a 5-year program, that means CMS funding will help train 20 residents in the specialty that treats blood vessel blockages and diseases of the veins and arteries generally associated with aging.

“The funding is amazing,” said Peter L. Faries, MD, a surgery professor and system chief of vascular surgery at the Icahn School of Medicine at Mount Sinai, New York City, who directs the residency program.

“We don’t have the capacity to provide an individual training program without the funding. It’s not economically feasible.”

The need for more vascular surgeons increases as the population continues to age, he said. Mount Sinai treats patients throughout New York, including underserved areas in Harlem, the Bronx, Washington Heights, Brooklyn, and Queens. “These individuals might not receive an appropriate level of vascular care if we don’t have clinicians to treat them.”

Of the recent funding, Dr. Faries said it’s taken the residency program 15 years of advocacy to increase by two slots. “It’s a long process to get funding.” Vascular training programs can remain very selective with Medicare funding, typically receiving two applicants for every position,” said Dr. Faries.
 

Pushing for More Funds

Nearly 98,000 students enrolled in medical school this year, according to the National Resident Matching Program. A total of 44,853 applicants vied for the 38,494 first-year residency positions and 3009 second-year slots, leaving 3350 medical school graduates without a match.

“There are not enough spots to meet the growing demand,” said Jesse M. Ehrenfeld, MD, MPH, immediate past president of the American Medical Association. “Graduate medical education funding has not kept up.”

Despite the increase in medical school graduates over the past two decades, Medicare-supported training opportunities remained frozen at the 1996 level. A limited number of training positions meant residency programs couldn’t expand the physician pipeline to offset an aging workforce, contributing to the shortage. “The way to solve this is to expand GME,” Dr. Ehrenfeld said. “We continue to advocate to remove the cap.”

Dr. Ehrenfeld also told this news organization that he doesn’t mind that Congress recently designated GME funding to certain specialties, such as psychiatry, because he believes the need is great for residency spots across the board. “The good news is people recognize it’s challenging to get much through Congress.” He’s optimistic, though, about recent legislative efforts to increase funding.

AAMC, representing about a third of the nation’s 1100 teaching hospitals and health systems, feels the same. Congress “acknowledges and continues to recognize that the shortage is not getting better, and one way to address it is to increase Medicare-supported GME positions,” said Leonard Marquez, senior director of government relations and legislative advocacy.

Still, he said that the Medicare funding bump is only making a small dent in the need. AAMC estimates the average cost to train residents is $23 billion annually, and Medicare only funds 20% of that, or $5 billion. “Our members are at the point where they say: We already can’t add new training positions,” Mr. Marquez said. He added that without increasing residency slots, patient care will suffer. “We have to do anything possible we can to increase access to care.”

Mr. Marquez also believes Medicare funding should increase residency positions across the specialty spectrum, not just for psychiatry and primary care. He said that the targeted funding may prevent some teaching hospitals from applying for residency positions if they need other types of specialists based on their community’s needs.

Among the current proposals before Congress, the Resident Physician Shortage Reduction Act of 2023 would add 14,000 Medicare-supported residency slots over 7 years. Mr. Marquez said it may be more realistic to expect fewer new slots. A decision on potential legislation is expected at the end of the year. He said that if the medical groups aren’t pleased with the decision, they’ll advocate again in 2025.

The need for more vascular surgeons increases as the population continues to age, he said. Mount Sinai treats patients throughout New York, including underserved areas in Harlem, the Bronx, Washington Heights, Brooklyn, and Queens. “These individuals might not receive an appropriate level of vascular care if we don’t have clinicians to treat them.”

Of the recent funding, Dr. Faries said it’s taken the residency program 15 years of advocacy to increase by two slots. “It’s a long process to get funding.” Vascular training programs can remain very selective with Medicare funding, typically receiving two applicants for every position,” said Dr. Faries.
 

Pushing for More Funds

Nearly 98,000 students enrolled in medical school this year, according to the National Resident Matching Program. A total of 44,853 applicants vied for the 38,494 first-year residency positions and 3009 second-year slots, leaving 3350 medical school graduates without a match.

“There are not enough spots to meet the growing demand,” said Jesse M. Ehrenfeld, MD, MPH, immediate past president of the American Medical Association. “Graduate medical education funding has not kept up.”

Despite the increase in medical school graduates over the past two decades, Medicare-supported training opportunities remained frozen at the 1996 level. A limited number of training positions meant residency programs couldn’t expand the physician pipeline to offset an aging workforce, contributing to the shortage. “The way to solve this is to expand GME,” Dr. Ehrenfeld said. “We continue to advocate to remove the cap.”

Dr. Ehrenfeld also told this news organization that he doesn’t mind that Congress recently designated GME funding to certain specialties, such as psychiatry, because he believes the need is great for residency spots across the board. “The good news is people recognize it’s challenging to get much through Congress.” He’s optimistic, though, about recent legislative efforts to increase funding.

AAMC, representing about a third of the nation’s 1100 teaching hospitals and health systems, feels the same. Congress “acknowledges and continues to recognize that the shortage is not getting better, and one way to address it is to increase Medicare-supported GME positions,” said Leonard Marquez, senior director of government relations and legislative advocacy.

Still, he said that the Medicare funding bump is only making a small dent in the need. AAMC estimates the average cost to train residents is $23 billion annually, and Medicare only funds 20% of that, or $5 billion. “Our members are at the point where they say: We already can’t add new training positions,” Mr. Marquez said. He added that without increasing residency slots, patient care will suffer. “We have to do anything possible we can to increase access to care.”

Mr. Marquez also believes Medicare funding should increase residency positions across the specialty spectrum, not just for psychiatry and primary care. He said that the targeted funding may prevent some teaching hospitals from applying for residency positions if they need other types of specialists based on their community’s needs.

Among the current proposals before Congress, the Resident Physician Shortage Reduction Act of 2023 would add 14,000 Medicare-supported residency slots over 7 years. Mr. Marquez said it may be more realistic to expect fewer new slots. A decision on potential legislation is expected at the end of the year. He said that if the medical groups aren’t pleased with the decision, they’ll advocate again in 2025.

Residency programs across the country may have a few more slots for incoming residents due to a recent bump in Medicare funding.

Case in point: The University of Alabama at Birmingham (UAB). The state has one of the top stroke rates in the country, and yet UAB has the only hospital in the state training future doctors to help stroke patients recover. “Our hospital cares for Alabama’s sickest patients, many who need rehabilitation services,” said Craig Hoesley, MD, senior associate dean for medical education, who oversees graduate medical education (GME) or residency programs.

After decades of stagnant support, a recent bump in Medicare funding will allow UAB to add two more physical medicine and rehabilitation residents to the four residencies already receiving such funding.

Medicare also awarded UAB more funding last year to add an addiction medicine fellowship, one of two such training programs in the state for the specialty that helps treat patients fighting addiction.

UAB is among healthcare systems and hospitals nationwide benefiting from a recent hike in Medicare funding for residency programs after some 25 years at the same level of federal support. Medicare is the largest funder of training positions. Otherwise, hospitals finance training through means such as state support.

The latest round of funding, which went into effect in July, adds 200 positions to the doctor pipeline, creating more openings for residents seeking positions after medical school.

In the next few months, the Centers for Medicare & Medicaid Services (CMS) will notify teaching hospitals whether they’ll receive the next round of Medicare funding for more residency positions. At that time, CMS will have awarded nearly half of the 1200 residency training slots Congress approved in the past few years. In 2020 — for the first time since 1996 — Congress approved adding 1000 residency slots at teaching hospitals nationwide. CMS awards the money for 200 slots each year for 5 years.

More than half of the initial round of funding focused on training primary care specialists, with other slots designated for mental health specialists. Last year, Congress also approved a separate allocation of 200 more Medicare-funded residency positions, with at least half designated for psychiatry and related subspecialty residencies to help meet the growing need for more mental health specialists. On August 1, CMS announced it would distribute the funds next year, effective in 2026.

The additional Medicare funding attempts to address the shortage of healthcare providers and ensure future access to care, including in rural and underserved communities. The Association of American Medical Colleges (AAMC) estimates the nation will face a shortage of up to 86,000 physicians by 2036, including primary care doctors and specialists.

In addition, more than 100 million Americans, nearly a third of the nation, don’t have access to primary care due to the physician shortages in their communities, according to the National Association of Community Health Centers.

Major medical organizations, medical schools, and hospital groups have been pushing for years for increased Medicare funding to train new doctors to keep up with the demand for healthcare services and offset the physician shortage. As a cost-saving measure, Medicare set its cap in 1996 for how much it will reimburse each hospital offering GME training. However, according to the medical groups that continue to advocate to Congress for more funding, the funding hasn’t kept pace with the growing healthcare needs or rising medical school enrollment.
 

Adding Residency Spots

In April, Dr. Hoesley of UAB spoke at a Congressional briefing among health systems and hospitals that benefited from the additional funding. He told Congressional leaders how the increased number of GME positions affects UAB Medicine and its ability to care for rural areas.

“We have entire counties in Alabama that don’t have physicians. One way to address the physician shortage is to grow the GME programs. The funding we received will help us grow these programs and care for residents in our state.”

Still, the Medicare funding is only a drop in the bucket, Dr. Hoesley said. “We rely on Medicare funding alongside other funding partners to train residents and expand our care across the state.” He said many UAB residency programs are over their Medicare funding cap and would like to grow, but they can’t without more funding.

Mount Sinai Health System in New York City also will be able to expand its residency program after receiving Medicare support in the latest round of funding. The health system will use the federal funds to train an additional vascular surgeon. Mount Sinai currently receives CMS funding to train three residents in the specialty.

Over a 5-year program, that means CMS funding will help train 20 residents in the specialty that treats blood vessel blockages and diseases of the veins and arteries generally associated with aging.

“The funding is amazing,” said Peter L. Faries, MD, a surgery professor and system chief of vascular surgery at the Icahn School of Medicine at Mount Sinai, New York City, who directs the residency program.

“We don’t have the capacity to provide an individual training program without the funding. It’s not economically feasible.”

The need for more vascular surgeons increases as the population continues to age, he said. Mount Sinai treats patients throughout New York, including underserved areas in Harlem, the Bronx, Washington Heights, Brooklyn, and Queens. “These individuals might not receive an appropriate level of vascular care if we don’t have clinicians to treat them.”

When Jennifer Welsh, a 40-year-old from New Britain, Connecticut, visited her doctor about pain in her joints and neck, her doctor sent her to the emergency department (ED) to rule out meningitis. The ED did rule that out, as well as strep, so Ms. Welsh went to her follow-up appointment a few days later, hoping for answers or at least more tests to get those answers.

Instead, the doctor — a different one from the same practice as her primary care physician (PCP) — wouldn’t even talk to Ms. Welsh about her symptoms because she couldn’t see the ED’s results and refused to view the results that Ms. Welsh could pull up online.

“She just completely shut me down,” Ms. Welsh recalled. “It was a really awful appointment, and I left in tears. I was in physical pain, I had just been to the ER, nothing is really resolved, I’m stressed out about it, and this woman is completely dismissing me.”

She had been able to schedule an appointment with her regular PCP later that week, but after the harrowing experience with this doctor, she wondered if her PCP would order the rheumatoid arthritis (RA) test that Ms. Welsh suspected she needed. So, she took matters into her own hands.

“I was searching for what test to ask for from my doctor,” she said, and she found that she could order it on her own from a major lab company she was already familiar with. For around $100, “I could get it done and see what it says on my own,” she said.

But that’s not how it worked out. Her regular PCP apologized for the other doctor’s behavior and ordered the RA test as well as additional tests — and got results while Ms. Welsh still waited for the one she ordered to arrive over a week later.

At first, Ms. Welsh was grateful she could order the RA test without her doctor’s referral. “I felt it gave me a sense of control over the situation that I felt really not in control of, until the system failed me, and I didn’t get the results,” she said. But then, “not having someone I could call and get an answer about why my tests were delayed, why I wasn’t able to access them, why it was taking so long — it was definitely anxiety-inducing.”
 

A Growing Market

Ms. Welsh is one of a growing number of patients who are ordering direct-to-consumer (DTC) lab tests without the recommendation or guidance of a doctor. They’re offered online by labs ranging from well-established giants like Quest and Labcorp to smaller, potentially less vetted companies, although some smaller companies contract with larger companies like Quest. Combined, the DTC market is projected to be worth $2 billion by 2025.

Yet the burgeoning industry has also drawn critiques from both bioethicists and privacy experts. A research letter in JAMA in 2023, for example, found that less than half of the 21 companies identified in an online search declared Health Insurance Portability and Accountability Act compliance, while more than half “indicated the potential use of consumer data for research purposes either internally or through third-party sharing.” That study found the most commonly offered tests were related to diabetes, the thyroid, and vitamin levels, and hormone tests for men and women, such as testosterone or estradiol.

But a number of companies also offer tests related to rheumatologic conditions. A handful of tests offered by Labcorp, for example, could be used in rheumatology, such as tests for celiac antibodies or high-sensitivity C-reactive protein. Quest similarly offers a handful of autoimmune-related tests. But other companies offer a long slate of autoimmune or antibody tests.

The antinuclear antibody (ANA) test and RA panel offered by Quest are the same tests, run and analyzed in the same labs, as those ordered by physicians and hospitals, according to James Faix, MD, the medical director of immunology at Quest Diagnostics. Their RA panel includes rheumatoid factor and anti-cyclic citrullinated peptide as well as antibody to mutated citrullinated vimentin, “which may detect approximately 10%-15%” of patients who test negative to the first two.

Quest’s ANA test with reflex costs $112, and its RA panel costs $110, price points that are similar across other companies’ offerings. Labcorp declined to respond to questions about its DTC tests, and several smaller companies did not respond to queries about their offerings. It can therefore be hard to assess what’s included or what the quality is of many DTC tests, particularly from smaller, less established companies.
 

Oversight and Quality Control

Anthony Killeen, MD, PhD, president of the Association for Diagnostics & Laboratory Medicine (ADLM) and director of Clinical Laboratories at the University of Minnesota Medical Center in Minneapolis, said via email that the ADLM supports “expanding consumer access to direct-to-consumer laboratory testing services that have demonstrated analytical and clinical validity and clinical utility,” given the importance of individuals learning about their health status and becoming more involved in health decisions. But the ADLM also recommends “that only CLIA-certified laboratories perform direct-to-consumer testing,” he said.

Association for Diagnostics & Laboratory Medicine

“There are direct-to-consumer tests on the market that are not medical-grade laboratory tests and that may be performed in nonaccredited laboratories,” Dr. Killeen said. “We advise consumers to steer clear of such tests.” The ADLM also encourages consumers to “work with qualified healthcare providers when making decisions based off the results they receive from any direct-to-consumer tests” and recommends that DTC test companies “provide consumers with sufficient information and/or access to expert help to assist them in ordering tests and interpreting the results.”

Yet it’s unclear how much support, if any, consumers can receive in terms of understanding what their tests mean. Most of the companies in the 2023 study offered optional follow-up with a healthcare professional, but these professionals ranged from physicians to “health coaches,” and all the companies had disclaimers that “test results did not constitute medical advice.”

At Quest, the only company to respond to this news organization’s request for comment, consumer-initiated tests ordered online are first reviewed by a physician at PWNHealth, an independent, third-party physician network, to determine that it’s appropriate before the lab order is actually placed.

“Once results are available, individuals have the option to discuss their results with an independent physician at no extra cost,” Dr. Faix said. ANA or RA results outside the normal ranges may trigger a “call from a PWNHealth healthcare coordinator, who can help provide information, suggestions on next steps, and set up time for the individual to speak with an independent physician to discuss questions or concerns regarding the results,” he said.

“Our goal is not to replace the role of a healthcare provider,” Dr. Faix said. “We are providing an alternate way for people to engage with the healthcare system that offers convenience, gives people more control over their own healthcare journeys, and meets them where they are, supporting both consumers and their care teams.” The company has expanded its offerings from an initial 30 tests made available in 2018 to over 130 today, deciding which to offer “based on consumer research and expertise of clinical experts.” The company has also “seen steady interest in our two consumer rheumatology offerings,” Dr. Faix said.
 

The DTC Landscape in Rheumatology

Within rheumatology, among the most popular tests is for ANA, based on the experience of Alfred Kim, MD, PhD, associate professor of medicine at Washington University School of Medicine in St Louis, Missouri.

Dr. Kim

“For a lot of people, losing control over their health is maybe the most frightening experience they can have, so I think a lot of patients use this as a way to kind of have ownership over their health,” Dr. Kim said. “Let’s say they’ve been to four doctors. No one can explain what’s going on. They’re getting frustrated, and so they just turn to solutions where they feel like they have ownership over the situation.”

Though the market is undoubtedly growing, the growth appears uneven across geography and institution types. Kim has seen a “fair number of referrals,” with patients coming in with results from a DTC test. Michael Putman, MD, MSci, assistant professor of medicine at the Medical College of Wisconsin in Milwaukee, hasn’t seen it much. “I know that patients can get testing done themselves independently, but I don’t have people routinely coming in with tests they’ve ordered in advance of our appointment,” Dr. Putman said, but, like Dr. Kim, he recognizes why patients might seek them out.

Risks vs Benefits

DTC testing is not an answer to the national shortage of rheumatologists, however, especially given the risks that Dr. Niewold, Dr. Putman, and Dr. Kim worry outweigh potential benefits. On the one hand, getting online test results may help expedite a referral to a specialist, Dr. Niewold said. But a long wait for that appointment could then easily become a bigger source of anxiety than comfort, Dr. Putman said.

“It’s a trade-off where you are accepting a lot more people getting false-positive diagnoses and spending months thinking they have some disease where they might not, in exchange for a couple people who would have had a delayed diagnosis,” Dr. Putman said. “There’s an enormous amount of existential suffering,” that’s familiar to rheumatologists because some patients may dread the diagnosis of a rheumatic disease the way they might fear a cancer diagnosis, especially if they have lost a family member to a condition that they suspect they share, he said. “To put yourself into an existential catastrophe — that’s not a small harm.”

Dr. Niewold agreed, pointing out that patients with a positive ANA test may “get unnecessarily worried and stay up all night reading about lupus, getting scared for weeks on end before seeing a specialist.” And there are financial harms as well for patients who may order the same test multiple times, or a whole slate of tests, that they don’t need for hundreds or thousands of dollars. There’s also the lost time and effort of researching a condition or even seeking out support groups that patients may pursue, Dr. Niewold said.

The likely biggest risk to individuals, however, is the potential for overdiagnosis or misdiagnosis.

“If someone comes in and they’ve read the textbook on lupus and they have a positive ANA, it’s really hard as a rheumatologist to walk that back,” Dr. Putman said. “The human mind is a powerful thing,” he added, and people who get a positive test will likely start to notice things like joint pain or a rash on their cheeks and begin attributing it to a diagnosis they risk convincing themselves they have. “When people come into your clinic not knowing what a disease would look like and they just tell you how they’re feeling, it’s a much cleaner and more honest way to approach diagnosis.”

Most patients likely don’t realize, for example, that none of the tests rheumatologists usually order are diagnostic in and of themselves, Dr. Niewold said. “They’re all kind of like stars in the constellation of a diagnosis,” he said. “They’re helpful, but none of them is sufficient by itself.”

Dr. Killeen agreed, noting that “consumers might not understand the nuances of these tests well enough to know whether it is appropriate to order them or how to interpret the results correctly.” Given the long-term implications of a diagnosis for a rheumatologic disease, “I would have concerns about consumers ordering and interpreting rheumatologic tests without working closely with their physicians,” Dr. Killeen said. “The main concern that lab experts have about direct-to-consumer tests is the potential for people to get misleading results and/or to misinterpret their results, which in turn could lead to people not getting the treatment they need or getting treatment when they don’t need any at all.”

It’s one thing for patients to come in asking for a particular treatment they may not need but which a doctor may be able to dissuade them from seeking. But Dr. Kim also pointed out the risk that patients may decide to treat themselves with therapies that haven’t undergone rigorous testing or haven’t been recommended by a physician.

“We tend to have people who come in with a pretty clear idea of what they want done, but the problem is, we don’t know if their reasoning is correct from a clinical perspective,” Dr. Kim said. Companies offer these tests with the belief that they’re “providing patients a choice, an option to take ownership,” he said, “but the potential harm can be realized very quickly because there are going to be people who are misdiagnosing themselves and, worse yet, may then pursue their own treatment plan that’s going in the opposite direction of where we think it needs to go.”

Or, on the flip side, if a patient erroneously believes they have the answer to what ails them, it may delay diagnosis of a more serious condition that’s rarer or harder to detect. Kim pointed to, for example, intravascular lymphoma, which is notoriously as difficult to identify as it is rare and aggressive. If a patient’s confirmation bias has led them to believe they have an autoimmune condition, they may not receive the more serious diagnosis until it’s advanced too far to treat.
 

Patient-Provider Relationship Friction

Another concern is how these tests may lead to confusion and frustration that can erode the patient-provider relationship, particularly because most patients don’t know how to interpret the results or understand the bigger context in which the results have to be interpreted. Many patients may think a test can come back with a binary answer, a positive or negative, and that means they do or don’t have a condition. That’s generally true for pregnancy tests, COVID tests, and sexually transmitted infection tests — the kinds of tests that have long been available to consumers and which have fairly straightforward answers.

But physicians know that’s not the case for many conditions, particularly those in rheumatology.

“In rheumatic diseases, because the tests have such marginal value in terms of diagnosis, almost always we develop a suspicion before we even think about ordering the tests, and then that dictates whether or not we cross that threshold,” Dr. Kim said. “A negative test doesn’t exclude the fact that you may have disease X, but a positive test also doesn’t mean you have disease X. All they provide is an idea of the risk.”

But some patients who come in with DTC test results have “already made the decision in their mind that they have a certain condition,” Dr. Kim said. “This is obviously dangerous because the majority of these patients do not have the condition they think they have, and it leaves a very uncomfortable feeling after the visit because they feel like they’ve been either betrayed by me or by the test, and they leave more confused.”

Patients may also come in with tests that a doctor isn’t familiar with or isn’t sure how to interpret on its own, at least for that particular patient.

“For ANA testing, we have a pretty good idea of its positive and negative predictive value because it’s ordered so much, but for many of these tests being offered, there are specific autoantibodies, and we tend to only get them in people where there’s a clinical suspicion,” Dr. Kim said. “Within that very specific context, we kind of understand what that value means, but if you give it to the general public, then those numbers aren’t as applicable and most likely overestimate the risk of disease.”

Even if providers consider the results of a DTC test in their differential, they may want to be sure it’s from a trustworthy source. “If a provider is uncertain about whether a direct-to-consumer testing company is reputable or about whether a direct-to-consumer test result is reliable, I would encourage them to consult with their laboratory medicine colleagues,” Dr. Killeen said.
 

Responding to Patients

Like any other patient coming to a clinical visit, the most common reason patients are likely ordering these tests is that they’re seeking answers. Kim doesn’t typically see patients doing their own monitoring for diagnosed conditions between visits — the expense would add up too quickly — or testing for genetic markers, which likely wouldn’t be very helpful either.

“Even though most of our diseases probably have a genetic underpinning, how much it contributes is always unclear,” Dr. Kim said. Even conditions with clear genetic variants, such as familial Mediterranean fever, spondyloarthritis, and Behçet disease, can only support a diagnosis, not diagnose it on its own, Dr. Killeen said. And these are not among the tests currently available on most DTC company sites.

While there are also tests that can offer information about genetic risks for certain medications, such as a thiopurine methyltransferase test to find out if a patient lacks the enzyme needed to break down the immunosuppressant drug azathioprine, Kim hasn’t seen patients seeking these out either.

“The more global and more compassionate way to think about this is that we have a lot of people who are struggling to understand what’s going on with their bodies, and most physicians really don’t know what the next steps are for these people,” Dr. Kim said. “They’re desperate, and their quality of life is so poor that they’re going to take extreme steps to try to manage their own frustration with this condition.”

That means clinicians’ most powerful tools when patients come in with DTC test results are their listening skills.

“Empathy is the most important thing, just being able to share the patient’s frustration to the point where they had to take matters into their own hands,” Dr. Kim said. “I think a lot of rheumatologists are actually pretty comfortable being in this position.”

Additionally, doctors should know that some patients may be engaging in attempts to self-diagnose, self-treat, or otherwise self-manage their symptoms or perceived condition. “They just need to be aware and try to make sure there’s no harm being done,” Dr. Kim said.

Ms. Welsh didn’t seek treatment or diagnosis on her own, but getting her test also did not give her the control she was seeking. “Looking back, it was kind of a waste of money, but it felt good in the moment,” Ms. Welsh said. “I was so upset, and I wanted that control, and in the end, it didn’t get me results any sooner, and it didn’t give me peace of mind.”

It was Ms. Welsh’s primary care doctor listening to her concerns, ordering the same test she had ordered with several others, and working with her to seek answers that reassured her that her provider cared about her well-being.

“A lot of what I do in my business is reassure people that you know what they have is treatable or not going to end their life as they know it,” Dr. Putman said. “And you certainly can’t reassure them if they’re not in your clinic yet.”

Dr. Putman has participated in clinical trials with AbbVie, consulting with Novartis and GSK, and clinical trials and consulting with Amgen and AstraZeneca. Dr. Niewold reported receiving research grants from EMD Serono and Zenas BioPharma and consulting for Thermo Fisher Scientific, Progentec Diagnostics, Roivant Sciences, AstraZeneca, S3 Connected Health, Flagship Pioneering, and Guidepoint. Dr. Kim reported sponsored research agreements with AstraZeneca, Bristol-Myers Squibb, Novartis, and CRISPR Therapeutics; royalties from Kypha; and consulting/speaking for Amgen, ANI Pharmaceuticals, Atara Biotherapeutics, Aurinia Pharmaceuticals, CARGO Therapeutics, Exagen Diagnostics, GSK, Hinge Bio, Kypha, Progentec Diagnostics, Synthekine, and UpToDate. Dr. Killeen had no relevant financial relationships to disclose.

Anthony Killeen, MD, PhD, president of the Association for Diagnostics & Laboratory Medicine (ADLM) and director of Clinical Laboratories at the University of Minnesota Medical Center in Minneapolis, said via email that the ADLM supports “expanding consumer access to direct-to-consumer laboratory testing services that have demonstrated analytical and clinical validity and clinical utility,” given the importance of individuals learning about their health status and becoming more involved in health decisions. But the ADLM also recommends “that only CLIA-certified laboratories perform direct-to-consumer testing,” he said.

Association for Diagnostics & Laboratory Medicine

“There are direct-to-consumer tests on the market that are not medical-grade laboratory tests and that may be performed in nonaccredited laboratories,” Dr. Killeen said. “We advise consumers to steer clear of such tests.” The ADLM also encourages consumers to “work with qualified healthcare providers when making decisions based off the results they receive from any direct-to-consumer tests” and recommends that DTC test companies “provide consumers with sufficient information and/or access to expert help to assist them in ordering tests and interpreting the results.”

Yet it’s unclear how much support, if any, consumers can receive in terms of understanding what their tests mean. Most of the companies in the 2023 study offered optional follow-up with a healthcare professional, but these professionals ranged from physicians to “health coaches,” and all the companies had disclaimers that “test results did not constitute medical advice.”

At Quest, the only company to respond to this news organization’s request for comment, consumer-initiated tests ordered online are first reviewed by a physician at PWNHealth, an independent, third-party physician network, to determine that it’s appropriate before the lab order is actually placed.

“Once results are available, individuals have the option to discuss their results with an independent physician at no extra cost,” Dr. Faix said. ANA or RA results outside the normal ranges may trigger a “call from a PWNHealth healthcare coordinator, who can help provide information, suggestions on next steps, and set up time for the individual to speak with an independent physician to discuss questions or concerns regarding the results,” he said.

“Our goal is not to replace the role of a healthcare provider,” Dr. Faix said. “We are providing an alternate way for people to engage with the healthcare system that offers convenience, gives people more control over their own healthcare journeys, and meets them where they are, supporting both consumers and their care teams.” The company has expanded its offerings from an initial 30 tests made available in 2018 to over 130 today, deciding which to offer “based on consumer research and expertise of clinical experts.” The company has also “seen steady interest in our two consumer rheumatology offerings,” Dr. Faix said.
 

The DTC Landscape in Rheumatology

Within rheumatology, among the most popular tests is for ANA, based on the experience of Alfred Kim, MD, PhD, associate professor of medicine at Washington University School of Medicine in St Louis, Missouri.

“For a lot of people, losing control over their health is maybe the most frightening experience they can have, so I think a lot of patients use this as a way to kind of have ownership over their health,” Dr. Kim said. “Let’s say they’ve been to four doctors. No one can explain what’s going on. They’re getting frustrated, and so they just turn to solutions where they feel like they have ownership over the situation.”

Though the market is undoubtedly growing, the growth appears uneven across geography and institution types. Kim has seen a “fair number of referrals,” with patients coming in with results from a DTC test. Michael Putman, MD, MSci, assistant professor of medicine at the Medical College of Wisconsin in Milwaukee, hasn’t seen it much. “I know that patients can get testing done themselves independently, but I don’t have people routinely coming in with tests they’ve ordered in advance of our appointment,” Dr. Putman said, but, like Dr. Kim, he recognizes why patients might seek them out.

Risks vs Benefits

DTC testing is not an answer to the national shortage of rheumatologists, however, especially given the risks that Dr. Niewold, Dr. Putman, and Dr. Kim worry outweigh potential benefits. On the one hand, getting online test results may help expedite a referral to a specialist, Dr. Niewold said. But a long wait for that appointment could then easily become a bigger source of anxiety than comfort, Dr. Putman said.

“It’s a trade-off where you are accepting a lot more people getting false-positive diagnoses and spending months thinking they have some disease where they might not, in exchange for a couple people who would have had a delayed diagnosis,” Dr. Putman said. “There’s an enormous amount of existential suffering,” that’s familiar to rheumatologists because some patients may dread the diagnosis of a rheumatic disease the way they might fear a cancer diagnosis, especially if they have lost a family member to a condition that they suspect they share, he said. “To put yourself into an existential catastrophe — that’s not a small harm.”

Dr. Niewold agreed, pointing out that patients with a positive ANA test may “get unnecessarily worried and stay up all night reading about lupus, getting scared for weeks on end before seeing a specialist.” And there are financial harms as well for patients who may order the same test multiple times, or a whole slate of tests, that they don’t need for hundreds or thousands of dollars. There’s also the lost time and effort of researching a condition or even seeking out support groups that patients may pursue, Dr. Niewold said.

The likely biggest risk to individuals, however, is the potential for overdiagnosis or misdiagnosis.

“If someone comes in and they’ve read the textbook on lupus and they have a positive ANA, it’s really hard as a rheumatologist to walk that back,” Dr. Putman said. “The human mind is a powerful thing,” he added, and people who get a positive test will likely start to notice things like joint pain or a rash on their cheeks and begin attributing it to a diagnosis they risk convincing themselves they have. “When people come into your clinic not knowing what a disease would look like and they just tell you how they’re feeling, it’s a much cleaner and more honest way to approach diagnosis.”

Most patients likely don’t realize, for example, that none of the tests rheumatologists usually order are diagnostic in and of themselves, Dr. Niewold said. “They’re all kind of like stars in the constellation of a diagnosis,” he said. “They’re helpful, but none of them is sufficient by itself.”

Dr. Killeen agreed, noting that “consumers might not understand the nuances of these tests well enough to know whether it is appropriate to order them or how to interpret the results correctly.” Given the long-term implications of a diagnosis for a rheumatologic disease, “I would have concerns about consumers ordering and interpreting rheumatologic tests without working closely with their physicians,” Dr. Killeen said. “The main concern that lab experts have about direct-to-consumer tests is the potential for people to get misleading results and/or to misinterpret their results, which in turn could lead to people not getting the treatment they need or getting treatment when they don’t need any at all.”

It’s one thing for patients to come in asking for a particular treatment they may not need but which a doctor may be able to dissuade them from seeking. But Dr. Kim also pointed out the risk that patients may decide to treat themselves with therapies that haven’t undergone rigorous testing or haven’t been recommended by a physician.

“We tend to have people who come in with a pretty clear idea of what they want done, but the problem is, we don’t know if their reasoning is correct from a clinical perspective,” Dr. Kim said. Companies offer these tests with the belief that they’re “providing patients a choice, an option to take ownership,” he said, “but the potential harm can be realized very quickly because there are going to be people who are misdiagnosing themselves and, worse yet, may then pursue their own treatment plan that’s going in the opposite direction of where we think it needs to go.”

Or, on the flip side, if a patient erroneously believes they have the answer to what ails them, it may delay diagnosis of a more serious condition that’s rarer or harder to detect. Kim pointed to, for example, intravascular lymphoma, which is notoriously as difficult to identify as it is rare and aggressive. If a patient’s confirmation bias has led them to believe they have an autoimmune condition, they may not receive the more serious diagnosis until it’s advanced too far to treat.
 

Patient-Provider Relationship Friction

Another concern is how these tests may lead to confusion and frustration that can erode the patient-provider relationship, particularly because most patients don’t know how to interpret the results or understand the bigger context in which the results have to be interpreted. Many patients may think a test can come back with a binary answer, a positive or negative, and that means they do or don’t have a condition. That’s generally true for pregnancy tests, COVID tests, and sexually transmitted infection tests — the kinds of tests that have long been available to consumers and which have fairly straightforward answers.

But physicians know that’s not the case for many conditions, particularly those in rheumatology.

“In rheumatic diseases, because the tests have such marginal value in terms of diagnosis, almost always we develop a suspicion before we even think about ordering the tests, and then that dictates whether or not we cross that threshold,” Dr. Kim said. “A negative test doesn’t exclude the fact that you may have disease X, but a positive test also doesn’t mean you have disease X. All they provide is an idea of the risk.”

But some patients who come in with DTC test results have “already made the decision in their mind that they have a certain condition,” Dr. Kim said. “This is obviously dangerous because the majority of these patients do not have the condition they think they have, and it leaves a very uncomfortable feeling after the visit because they feel like they’ve been either betrayed by me or by the test, and they leave more confused.”

Patients may also come in with tests that a doctor isn’t familiar with or isn’t sure how to interpret on its own, at least for that particular patient.

“For ANA testing, we have a pretty good idea of its positive and negative predictive value because it’s ordered so much, but for many of these tests being offered, there are specific autoantibodies, and we tend to only get them in people where there’s a clinical suspicion,” Dr. Kim said. “Within that very specific context, we kind of understand what that value means, but if you give it to the general public, then those numbers aren’t as applicable and most likely overestimate the risk of disease.”

Even if providers consider the results of a DTC test in their differential, they may want to be sure it’s from a trustworthy source. “If a provider is uncertain about whether a direct-to-consumer testing company is reputable or about whether a direct-to-consumer test result is reliable, I would encourage them to consult with their laboratory medicine colleagues,” Dr. Killeen said.
 

Responding to Patients

Like any other patient coming to a clinical visit, the most common reason patients are likely ordering these tests is that they’re seeking answers. Kim doesn’t typically see patients doing their own monitoring for diagnosed conditions between visits — the expense would add up too quickly — or testing for genetic markers, which likely wouldn’t be very helpful either.

“Even though most of our diseases probably have a genetic underpinning, how much it contributes is always unclear,” Dr. Kim said. Even conditions with clear genetic variants, such as familial Mediterranean fever, spondyloarthritis, and Behçet disease, can only support a diagnosis, not diagnose it on its own, Dr. Killeen said. And these are not among the tests currently available on most DTC company sites.

While there are also tests that can offer information about genetic risks for certain medications, such as a thiopurine methyltransferase test to find out if a patient lacks the enzyme needed to break down the immunosuppressant drug azathioprine, Kim hasn’t seen patients seeking these out either.

“The more global and more compassionate way to think about this is that we have a lot of people who are struggling to understand what’s going on with their bodies, and most physicians really don’t know what the next steps are for these people,” Dr. Kim said. “They’re desperate, and their quality of life is so poor that they’re going to take extreme steps to try to manage their own frustration with this condition.”

That means clinicians’ most powerful tools when patients come in with DTC test results are their listening skills.

“Empathy is the most important thing, just being able to share the patient’s frustration to the point where they had to take matters into their own hands,” Dr. Kim said. “I think a lot of rheumatologists are actually pretty comfortable being in this position.”

Additionally, doctors should know that some patients may be engaging in attempts to self-diagnose, self-treat, or otherwise self-manage their symptoms or perceived condition. “They just need to be aware and try to make sure there’s no harm being done,” Dr. Kim said.

Ms. Welsh didn’t seek treatment or diagnosis on her own, but getting her test also did not give her the control she was seeking. “Looking back, it was kind of a waste of money, but it felt good in the moment,” Ms. Welsh said. “I was so upset, and I wanted that control, and in the end, it didn’t get me results any sooner, and it didn’t give me peace of mind.”

It was Ms. Welsh’s primary care doctor listening to her concerns, ordering the same test she had ordered with several others, and working with her to seek answers that reassured her that her provider cared about her well-being.

“A lot of what I do in my business is reassure people that you know what they have is treatable or not going to end their life as they know it,” Dr. Putman said. “And you certainly can’t reassure them if they’re not in your clinic yet.”

Dr. Putman has participated in clinical trials with AbbVie, consulting with Novartis and GSK, and clinical trials and consulting with Amgen and AstraZeneca. Dr. Niewold reported receiving research grants from EMD Serono and Zenas BioPharma and consulting for Thermo Fisher Scientific, Progentec Diagnostics, Roivant Sciences, AstraZeneca, S3 Connected Health, Flagship Pioneering, and Guidepoint. Dr. Kim reported sponsored research agreements with AstraZeneca, Bristol-Myers Squibb, Novartis, and CRISPR Therapeutics; royalties from Kypha; and consulting/speaking for Amgen, ANI Pharmaceuticals, Atara Biotherapeutics, Aurinia Pharmaceuticals, CARGO Therapeutics, Exagen Diagnostics, GSK, Hinge Bio, Kypha, Progentec Diagnostics, Synthekine, and UpToDate. Dr. Killeen had no relevant financial relationships to disclose.

When Jennifer Welsh, a 40-year-old from New Britain, Connecticut, visited her doctor about pain in her joints and neck, her doctor sent her to the emergency department (ED) to rule out meningitis. The ED did rule that out, as well as strep, so Ms. Welsh went to her follow-up appointment a few days later, hoping for answers or at least more tests to get those answers.

Instead, the doctor — a different one from the same practice as her primary care physician (PCP) — wouldn’t even talk to Ms. Welsh about her symptoms because she couldn’t see the ED’s results and refused to view the results that Ms. Welsh could pull up online.

“She just completely shut me down,” Ms. Welsh recalled. “It was a really awful appointment, and I left in tears. I was in physical pain, I had just been to the ER, nothing is really resolved, I’m stressed out about it, and this woman is completely dismissing me.”

She had been able to schedule an appointment with her regular PCP later that week, but after the harrowing experience with this doctor, she wondered if her PCP would order the rheumatoid arthritis (RA) test that Ms. Welsh suspected she needed. So, she took matters into her own hands.

“I was searching for what test to ask for from my doctor,” she said, and she found that she could order it on her own from a major lab company she was already familiar with. For around $100, “I could get it done and see what it says on my own,” she said.

But that’s not how it worked out. Her regular PCP apologized for the other doctor’s behavior and ordered the RA test as well as additional tests — and got results while Ms. Welsh still waited for the one she ordered to arrive over a week later.

At first, Ms. Welsh was grateful she could order the RA test without her doctor’s referral. “I felt it gave me a sense of control over the situation that I felt really not in control of, until the system failed me, and I didn’t get the results,” she said. But then, “not having someone I could call and get an answer about why my tests were delayed, why I wasn’t able to access them, why it was taking so long — it was definitely anxiety-inducing.”
 

A Growing Market

Ms. Welsh is one of a growing number of patients who are ordering direct-to-consumer (DTC) lab tests without the recommendation or guidance of a doctor. They’re offered online by labs ranging from well-established giants like Quest and Labcorp to smaller, potentially less vetted companies, although some smaller companies contract with larger companies like Quest. Combined, the DTC market is projected to be worth $2 billion by 2025.

Yet the burgeoning industry has also drawn critiques from both bioethicists and privacy experts. A research letter in JAMA in 2023, for example, found that less than half of the 21 companies identified in an online search declared Health Insurance Portability and Accountability Act compliance, while more than half “indicated the potential use of consumer data for research purposes either internally or through third-party sharing.” That study found the most commonly offered tests were related to diabetes, the thyroid, and vitamin levels, and hormone tests for men and women, such as testosterone or estradiol.

But a number of companies also offer tests related to rheumatologic conditions. A handful of tests offered by Labcorp, for example, could be used in rheumatology, such as tests for celiac antibodies or high-sensitivity C-reactive protein. Quest similarly offers a handful of autoimmune-related tests. But other companies offer a long slate of autoimmune or antibody tests.

The antinuclear antibody (ANA) test and RA panel offered by Quest are the same tests, run and analyzed in the same labs, as those ordered by physicians and hospitals, according to James Faix, MD, the medical director of immunology at Quest Diagnostics. Their RA panel includes rheumatoid factor and anti-cyclic citrullinated peptide as well as antibody to mutated citrullinated vimentin, “which may detect approximately 10%-15%” of patients who test negative to the first two.

Quest’s ANA test with reflex costs $112, and its RA panel costs $110, price points that are similar across other companies’ offerings. Labcorp declined to respond to questions about its DTC tests, and several smaller companies did not respond to queries about their offerings. It can therefore be hard to assess what’s included or what the quality is of many DTC tests, particularly from smaller, less established companies.

Anthony Killeen, MD, PhD, president of the Association for Diagnostics & Laboratory Medicine (ADLM) and director of Clinical Laboratories at the University of Minnesota Medical Center in Minneapolis, said via email that the ADLM supports “expanding consumer access to direct-to-consumer laboratory testing services that have demonstrated analytical and clinical validity and clinical utility,” given the importance of individuals learning about their health status and becoming more involved in health decisions. But the ADLM also recommends “that only CLIA-certified laboratories perform direct-to-consumer testing,” he said.

ANA or RA results outside the normal ranges may trigger a “call from a PWNHealth healthcare coordinator, who can help provide information, suggestions on next steps, and set up time for the individual to speak with an independent physician to discuss questions or concerns regarding the results,” he said.

“Our goal is not to replace the role of a healthcare provider,” Dr. Faix said. “We are providing an alternate way for people to engage with the healthcare system that offers convenience, gives people more control over their own healthcare journeys, and meets them where they are, supporting both consumers and their care teams.” The company has expanded its offerings from an initial 30 tests made available in 2018 to over 130 today, deciding which to offer “based on consumer research and expertise of clinical experts.” The company has also “seen steady interest in our two consumer rheumatology offerings,” Dr. Faix said.

Meet your new patients.

You can’t see them, but trillions — maybe quadrillions — of them travel in and out of your practice every day. They’re hungry, mysterious, community-oriented, and small. Very, very small.

They’re the microbes occupying your current patients’ guts.

Someday soon, you’ll prescribe medicine not just for humans but also for these microbes.

“I am convinced in the future our medicine cabinets are going to have not just medications like a statin for treating us, but [also] pills that treat and inhibit an enzyme in our microbes and elicit a health benefit in some chronic disease,” said Stanley Hazen, MD, PhD, co-section head of Preventive Cardiology & Rehabilitation and director of the Center for Microbiome & Human Health at Cleveland Clinic, Cleveland, Ohio.

Evidence is mounting that the gut microbiome influences just about every major human disease. These trillions of microbes use our food to generate substances called metabolites that can protect or harm our health, with consequences reaching far beyond our gastrointestinal tracts.

Research has linked microbial metabolites to diabetes, cardiovascular disease, liver disease, obesity, high blood pressure, neurological disorders, depression, cancer, and more. Gastroenterologist Christopher Damman, MD, a clinical associate professor at the University of Washington Medical Center, Seattle, calls it a “growing theme” in microbiome science.

Now scientists are developing treatments targeting gut microbial pathways, designed to eliminate the bad metabolites and boost the good metabolites.

One close to human therapeutic intervention is an oral treatment from Dr. Hazen’s lab targeting the metabolite trimethylamine N-oxide (TMAO), a predictor of and contributor to both cardiovascular disease and chronic kidney disease. The drug, which blocks TMAO formation, is nearing clinical trials, Dr. Hazen said.

The advantage is safety. By targeting the microbe instead of, say, an enzyme, the host (your patient) must absorb little if any drug.

Implications for the future of medicine are huge. “Gut microbial pathways contribute to diabetes, obesity, virtually everything,” Dr. Hazen said. “Therapies that target gut microbiome processes will probably even be used for psychiatric disorders within, I’ll say, 10 or 20 years.”
 

The Science

About 100 trillion strains of bacteria live in our guts. As humans have evolved, so have they.

Between 70% and 90% come from the phyla Firmicutes and Bacteroidetes, with person-to-person variation shaped by genetics, environment, and lifestyle.

“Everyone’s microbiome is subtly different,” said Dr. Hazen. “So the combination of what they’re making is different. All these different biologically active compounds are influencing us in subtly different ways.”

How it works: When you eat, your microbes eat, breaking down food into metabolites that interact with the thin layer of epithelial cells lining your gut. Some can be absorbed through the lining and into your bloodstream, a phenomenon known as “leaky gut.” Once in your blood, they can trigger irritation and inflammation, potentially leading to a wide variety of health issues, from gas and bloating to autoimmune conditions and mood disorders.

“On the other side of the epithelial lining, you have some of the largest concentrations of immune cells,” said Narendra Kumar, PhD, associate professor of pharmaceutical sciences at Texas A&M University, College Station, Texas.

Metabolites can influence how these immune cells work, possibly explaining why each person’s immune system behaves distinctively.

Of the 1000-plus metabolites linked to the gut microbiome, scientists have identified several that matter.

Short-chain fatty acids. When we eat fiber, colon bacteria ferment it into the beneficial short-chain fatty acids acetate, propionate, and butyrate. These bind to receptors in muscle, liver, and fat tissue, affecting the secretion of gut hormones and peptides related to appetite, inflammation, energy expenditure, and fat oxidation.

Butyrate has been linked to health benefits. It supports the integrity of the gut’s lining, stifling pathogenic gut bacteria, fighting cancer-promoting inflammation, and protecting against obesity and diabetes. It can function as a prebiotic, helping beneficial bacteria thrive. And recent studies linked an abundance of butyrate-producing bacteria with reduced bone fracture risk and hospitalization for infectious disease.

TMAO and phenylacetylglutamine. When we eat foods rich in animal proteins — think eggs, milk, fish, and especially red meat — some gut bacteria convert nutrients like choline and L-carnitine into TMAO and phenylalanine into phenylacetylglutamine. Research conducted by Dr. Hazen’s lab and replicated by others has linked both metabolites to heart problems.

In a landmark study from Dr. Hazen’s group, healthy adults who went on to develop coronary artery disease had significantly higher plasma TMAO levels than those who did not wind up with the condition. The association remained strong, even after controlling for risk factors like age, sex, smoking, high blood pressure, and high cholesterol.

In preclinical studies, elevated TMAO enhanced cardiovascular disease. TMAO-producing microbes also accentuated cardiovascular disease phenotypes in mouse models, while blocking these pathways inhibited the phenotypes.

Research suggests TMAO may harm cardiomyocytes (cells that contract and relax the heart) in dozens of ways, such as activating the expression of proteins to promote hypertrophy and fibrosis, decreasing mitochondrial function, and disrupting calcium signaling.

Another study linked phenylacetylglutamine levels to cardiac event risk in patients with heart failure. Recent mechanistic investigations suggest the metabolite alters signaling in a beta-adrenergic receptor involved in our fight-or-flight response, said Hazen.

“It’s like a rheostat on the light switch, a dimmer switch, and it’s what’s called a negative allosteric modulator,” he said. “It’s the first time that this type of behavior has ever been shown to be present for a gut microbial metabolite and a host receptor.”

Tryptophan metabolites. Microbes in your colon can convert the amino acid tryptophan, also found in animal-based foods, into neurotransmitters like serotonin and melatonin.

“The enteric nervous system, the nervous system around the gut, is immense,” said James Versalovic, MD, PhD, professor of pathology and immunology at Baylor College of Medicine, Houston. “The gut-brain axis has become a very fertile area of research.”

Lesser-known tryptophan metabolites — like indole, tryptamine, and indoleethanol — have been linked to benefits like fortifying the gut barrier, promoting the release of glucagon-like peptide 1 to reduce appetite, and protecting the liver from hepatitis. However, indole can also spur the production of indoxyl sulfate, a toxin linked to chronic kidney disease. 

Bile acid byproducts. Your gut bugs also feast on (and transform) bile acids before they reabsorb and travel back to the liver.

Research is gaining traction on these secondary bile acids, which can affect inflammation and immune function in helpful and harmful ways.

One area of interest is how microbes break down hormones in bile. A recent study from Harvard showed that gut microbes convert corticoid hormones in bile into progestins, which could affect postpartum depression risk. And researchers are exploring the estrobolome — a gut microbial community dedicated to breaking down estrogen into its active form so it can be reabsorbed.

“Depending on the bacteria that you have, more or less can be recirculated back into your blood,” said Beatriz Peñalver Bernabé, PhD, an assistant professor of biomedical engineering and urology at the University of Illinois Chicago. “So you may be producing the same amount of estrogen, but depending on the bacteria you have, the real free estrogen that can bind to your cells may be very different.”

The gut microbiome can also regulate testosterone, with studies showing microbial differences in men with high testosterone vs those with less.
 

What Patients Can Do Now

Advances in the field of microbiome research — and the related “gut health” wellness craze — have spawned all kinds of new microbiome-based products: Like over-the-counter probiotic supplements and at-home test kits, which let you send a stool sample for analysis to reveal microbiome health and personalized diet recommendations.

But the science behind these tests is still evolving, said Dr. Damman. “The clinical inferences and applications are still pretty limited.”

For most people, the first step to fostering healthier microbial metabolites is much simpler: Diversify your diet.

“A lot of folks are missing that diversity,” Dr. Damman said.

“Eat foods and experiment with foods that you might not eat all the time,” especially fruits, vegetables, nuts, seeds, and beans.

Another strategy: Eat foods with probiotic bacteria. “I view it as an insurance policy,” said Dr. Versalovic, “fortifying my gut with probiotics, with daily yogurt, for example, at breakfast.”

Fermented foods like kimchi and kombucha can also increase microbial diversity and can even contain health-promoting postbiotics, research shows.

As for probiotic supplements, the jury’s still out.

Certain strains of probiotic bacteria may be beneficial for some patients, like those with diarrhea, Crohn’s disease, and irritable bowel syndrome, according to World Gastroenterology Organisation guidelines.

As with other interventions, individual responses can vary. A Stanford study showed that some people with metabolic syndrome improved when taking a probiotic, while others didn’t. Both groups had key differences in gut bacteria and dietary habits.

For best results, such microbiome-based interventions will need to be personalized, experts say. And the technology to do that is coming sooner than you might think.
 

Microbiome’s Medical Future: ‘We Are on the Cusp of a New Era’

In just a few years, artificial intelligence (AI) models could predict gut microbial composition based on data such as dietary habits and household characteristics, Dr. Kumar said.

Advancements in metabolomics and bioinformatics could soon help physicians and patients personalize their treatment approaches, said Dr. Damman.

One focus will be on fortifying the gut with whatever it lacks.

“In those individuals where certain microbes are missing, (a) how could we add them back potentially in a rational, science-driven way, and (b) maybe some of those factors that the microbes are producing out the other ends, you could give directly,” said Dr. Damman.

For example, multiple companies make butyrate as a dietary supplement, although the research is too early to support widespread use. Another option could be eating something that spurs butyrate production. One small study found that a fiber supplement formulated to increase butyrate levels in the colon reduced participants’ systolic blood pressure by an average of six points.

Another option could be synbiotics, products that combine bacteria and the food source they feed on. “If you just give a diet-based therapy, it is not going to work as much. Because what if that diet needs certain bacteria to have these beneficial metabolites?” said Ashutosh Mangalam, PhD, associate professor of pathology at the University of Iowa Carver College of Medicine, Iowa City.

Dr. Mangalam studies links between bacterial metabolism of phytoestrogens in soy foods and multiple sclerosis (MS) development. He is using AI to understand differences in metabolites in patients with MS vs healthy controls to determine how to target them.

Gut microbial metabolites could also affect disease screening and intervention. What if gut microbe sequencing could predict a pregnant person’s risk of developing depression, something now assessed through simple questionnaires?

“Imagine that your doctor says, ‘Okay, give me a poop sample,’ ” Dr. Bernabé said. “Then they phenotype it, and then they put it in your electronic medical record, and they say, ‘Well, you have high likelihood of having a mood disorder down the line in your pregnancy. Why don’t we directly refer you to a provider now so you can follow up?’ ”

Research is already underway to understand how metabolites might be linked to pregnancy outcomes, complex regional pain syndrome, and anxiety. Researchers are also investigating whether supplementing our diets with things like prebiotic fibers, apple polyphenols, or tomato paste might influence metabolites. And fecal transplants that shift the gut microbiome and metabolites could have potential in diseases like unexplained atherosclerosis, post-COVID syndrome, and hidradenitis suppurativa.

Dr. Hazen’s discovery linking TMAO with cardiovascular risk has already changed clinical practice. A blood TMAO test can help identify patients at risk who may not have traditional risk factors. “Millions have been done,” Dr. Hazen said.

Meanwhile, his drug targeting the TMAO pathway inches closer to clinical trials.

“In an animal model, we elicit improvement in heart failure, renal disease, atherosclerosis, thrombosis, aortic aneurysm, and obesity,” Dr. Hazen said. The first clinical trials will focus on renal disease.

As with any drug, the road to approval takes time. And success is not guaranteed.

But Dr. Hazen for one is optimistic.

“We are on the cusp of a new era,” Dr. Hazen said. “Like when humans first discovered insulin and glucagon were hormones that impact sugar metabolism. We now recognize myriad new ‘hormones’ in the form of gut microbiome metabolites that impact our physiology and susceptibility to diseases.”
