Clinical question: Are patients with obstructive sleep apnea (OSA) and preoperative hypercapnia more likely to experience postoperative complications than those without?

Background: Obesity hypoventilation syndrome (OHS) is known to increase medical morbidity in patients with OSA, but its impact on postoperative outcome is unknown.

Study design: Retrospective cohort study.

Setting: Single tertiary-care center.

Synopsis: The study examined 1,800 patients with body mass index (BMI) ≥30 who underwent polysomnography, elective non-cardiac surgery (NCS), and had a blood gas performed. Of those, 194 patients were identified as having OSA with hypercapnia, and 325 were identified as having only OSA. Investigators found that the presence of hypercapnia in patients with OSA, whether from OHS, COPD, or another cause, was associated with worse postoperative outcomes. They found a statistically significant increase in postoperative respiratory failure (21% versus 2%), heart failure (8% versus 0%), tracheostomy (2% versus 1%), and ICU transfer (21% versus 6%). Mortality data did not reach significance.

The major limitation to the study is that hypercapnia is underrecognized in this patient population, and as a result, only patients who had a blood gas were included; many hypercapnic patients may have had elective NCS without receiving a blood gas and were thus excluded.

Bottom line: Consider performing a preoperative blood gas in patients with OSA undergoing elective NCS to help with postoperative complication risk assessment.

Clinical question: How useful are rapid immunoassays (RIs) compared to other tests for heparin-induced thrombocytopenia (HIT)?

Background: HIT is a clinicopathologic diagnosis, which traditionally requires clinical criteria and laboratory confirmation through initial testing with enzyme-linked immunosorbent assay (ELISA) and “gold standard” testing with washed platelet functional assays when available. There are an increasing number of RIs available, which have lab turnaround times of less than one hour. Their clinical utility is not well understood.

Study design: Meta-analysis.

Setting: Twenty-three studies.

Synopsis: The authors found 23 articles to include for review. These studies included 5,637 unique patients and included heterogeneous (medical, surgical, non-ICU) populations. These articles examined six different rapid immunoassays, which have been developed in recent years. All RIs examined had excellent negative predictive values (NPVs) ranging from 0.99 to 1.00, though positive predictive values (PPVs) had much wider variation (0.42–0.71). The greatest limitation in this meta-analysis is that 17 of the studies were marked as “high risk of bias” because they did not compare the RIs to the “gold standard” assay.

Bottom line: RIs for the diagnosis of HIT have very high NPVs and may be usefully incorporated into the diagnostic algorithm for HIT, but they cannot take the place of “gold standard” washed platelet functional assays.

Clinical question: Is a delay in completion of hospital discharge summary associated with hospital readmissions?

Background: Inpatient discharge summaries serve as a communication tool to future care providers. Previous studies have shown mixed impact on the timeliness of discharge summaries on hospital readmissions.

Study design: Retrospective cohort study.

Setting: Adult medical patients at Johns Hopkins University Hospital, Baltimore.

Synopsis: Study authors examined the time between hospital discharge and discharge summary completion on 87,994 hospitalizations to assess whether a delay increased the odds of hospital readmission. In those hospitalizations, 14,248 patients (16.2%) were readmitted within 30 days of discharge. There was a statistically significant adjusted odds ratio of 1.09 (P=0.001) for readmission associated with discharge summaries completed more than three days after discharge.

The main advantage of the study is that the investigators reviewed a large number of hospitalizations. The major limitation is that deaths or admissions to other hospitals within 30 days of discharge were not measured.

Bottom line: Completing a discharge summary within three days of discharge may decrease the risk of 30-day readmission.

Clinical question: Does assigning a single medical team to a nursing unit (regionalizing) improve communication and prevent adverse events?

Background: Many factors impact communication in healthcare delivery. Failures in communication are a known source of adverse events in hospital care. Previous studies of the impact of regionalized care (assigning medical physician teams to nursing units) on communication and outcomes have had mixed results.

Study design: Pre-post intervention cohort analysis.

Setting: Brigham and Women’s Hospital, Boston.

Synopsis: Three medical teams were assigned to 15-bed nursing units with structured multidisciplinary meeting times for one year. Assessments of concordance of care plan and adverse event detection (with a focus on adverse drug events and poor glycemic control) were performed before and after this assignment. Regionalization of care in the study site improved recognition of care team members (0.56 versus 0.86; P<0.001), discussion of care plan (0.73 versus 0.88; P<0.001), and agreement on estimated discharge date (0.56 versus 0.68; P<0.003). However, it did not significantly improve nurse and physician concordance of the plan or reduce the odds of preventable adverse events.

This study may not have captured an impact on more subtle adverse events or other aspects of interprofessional relationships that enhance patient care.

Bottom line: Regionalization effectively promotes communication but may not lead to patient safety improvements.

Clinical question: What is the association between detectable cardiac troponin (cTn) levels and outcomes in persons hospitalized with acute decompensated heart failure (ADHF)?

Background: There are millions of ADHF hospitalizations per year, and all-cause mortality and readmission rates are high. Efforts to better risk-stratify such patients have included measuring cTn levels and determining risk of increased length of stay, hospital readmission, and mortality.

Study design: Systematic review and meta-analysis.

Setting: Twenty-six observational cohort studies.

Synopsis: Compared with an undetectable cTn, detectable or elevated cTn levels were associated with greater length of stay (odds ratio [OR], 1.05; 95% CI, 1.01¬–1.10) and greater in-hospital death (OR, 2.57; 95% CI, 2.27–2.91). ADHF patients with detectable or elevated cTn were also at increased risk for mortality and composite of mortality and readmission over the short, intermediate, and long term. Reviewers eventually considered the overall association of a detectable or elevated troponin with mortality and readmission as moderate (relative association measure >2.0).

Meanwhile, few studies in this analysis showed a continuous and graded relationship between cTn levels and clinical outcomes.

Limitations of the review include arbitrarily stratifying groups by the level of cTn from assays whose lower limit of detection vary. The authors also admit the various associations are likely affected by several confounders for which they could not adjust because individual participant data were unavailable.

Finally, while acknowledging patients with chronic stable heart failure often have baseline elevated cTn levels, accounting for this in the analysis was limited.

Bottom line: A detectable or elevated level of cTn during ADHF hospitalization leads to worse outcomes both during and after discharge.

Clinical question: Which cardiovascular imaging modalities can augment triage of ED patients with chest pain?

Background: Because absolute event rates for patients with chest pain and normal initial ECG findings are not low enough to drive discharge triage decisions, and findings that patients with acute myocardial infarction (AMI) are inadvertently discharged because of less-sensitive troponin assays, there is great interest in what imaging modalities can facilitate safer triages.

Study design: Clinical guideline.

Setting: Meta-analysis of studies in multiple clinical settings.

Synopsis: This guideline adopted two pathways: an early assessment pathway, which considers imaging without the need for serial biomarker analysis, and an observational pathway, which involves serial biomarker testing.

For the early assessment pathway, when ECG and/or biomarker analysis is unequivocally positive for ischemia, all rest-imaging modalities are rarely appropriate. When the initial troponin level is equivocal, both rest single-photon emission computed tomography (SPECT) and coronary CT angiography (CCTA) are appropriate, though rest echocardiography and rest cardiovascular magnetic resonance (CMR) may be alternatives. Resting imaging may also be appropriate when chest pain resolves prior to evaluation and/or initial ECG plus troponin is non-ischemic/normal.

In the observational pathway, for patients with ECG changes and/or serial troponins unequivocally positive for AMI, only cardiac catheterization is recommended. When serial ECGs/troponins are borderline, stress-test modalities and CCTA are appropriate. When serial ECGs/ troponins are negative, outpatient testing may be appropriate.

Bottom line: Experts recommend cardiac catheterization as the imaging modality of choice for patients with an unequivocal AMI diagnosis. When ECG and/or biomarkers are equivocal or negative, outpatient evaluation may be appropriate.

Bottom line: Experts recommend cardiac catheterization as the imaging modality of choice for patients with an unequivocal AMI diagnosis. When ECG and/or biomarkers are equivocal or negative, outpatient evaluation may be appropriate.

Clinical question: Will a multifaceted quality improvement initiative targeted at hospitalists reduce inpatient laboratory costs?

Background: Routine inpatient laboratory testing is a well-recognized area of healthcare waste and was highlighted by the American Board of Internal Medicine Choosing Wisely campaign as a practice that should be questioned. Multifaceted quality improvement interventions, especially those that incorporate interventions beyond education, are more successful at achieving sustainable change.

Study design: Retrospective, controlled, interrupted time series study.

Setting: University of Utah, academic general internal medicine hospitalist service.

Synopsis: The intervention group, a teaching hospitalist service, received targeted education, cost feedback comparing individual provider performance, and divisional financial incentives. Additionally, a standardized rounding checklist was implemented and completed by rotating medical students. The control group included all non-hospitalist services. Approximately 20% of the 31,896 encounters measured in pre-intervention and post-intervention periods took place in the intervention group. Lab cost per day was reduced from $138 to $123 in the intervention group (P<0.001), while cost per day was non-significantly increased in the control group from $130 to $132 (P=0.37). Limitations of this study include the fact that the University of Utah already prioritizes high-value care and utilizes a local tool to provide individual cost and ordering feedback to providers as well as the financial incentives. Additionally, the use of medical students to implement the rounding checklist may not be feasible in many practice settings.

Bottom line: An approach of targeted education, direct provider feedback, consistent use of a rounding checklist, and financial incentives may decrease lab utilization.

Clinical question: Does discharge planning improve length of stay and reduce readmission rates compared to usual care?

Background: Discharge planning is accomplished to varying degrees for patients admitted to an acute-care hospital. Goals include improving the quality of care transitions as well as cost containment.

Study design: Meta-analysis.

Setting: Thirty studies that examined the effects of discharge planning.

Synopsis: In 12 studies focusing on older patients, discharge planning resulted in a reduction in hospital length of stay by 0.73 days (95% CI, -1.33 to -0.12). Readmission rates for this population were reduced, with approximately three fewer readmissions per 100 patients (relative risk, 0.87; 95% CI, 0.79–0.97). These results were not consistent for other populations, including surgical patients and patients admitted following a fall. No conclusions could be drawn on other outcomes, including patient and provider satisfaction, location of eventual discharge, and mortality. The effect of discharge planning on cost of care was uncertain based on the five trials reporting varied outcomes. Limitations include the varied descriptions of what constituted discharge planning and the lack of reporting on the role of communication in the process. Given the Centers for Medicare & Medicaid Services’ requirements for discharge planning, it is difficult to estimate the effect this study has on clinical practice.

Further study is needed to determine which aspects of discharge planning lead to desired clinical outcomes and the effects on overall cost of care.

Bottom line: Discharge planning in older patients with medical admissions appears to marginally reduce length of stay and readmission rates without a clear effect on cost of care.

Clinical question: Can a nurse-driven early ambulation program aimed at all hospitalized adults increase patient mobility and decrease length of stay?

Background: Many adults experience decline of functional abilities during their hospitalization. Interventions to increase early mobilization of patients in the ICU have been associated with decreased length of stay, decreased costs, and improved patient satisfaction. Previous studies of interventions in non-ICU patients have used specialized staff or have targeted select patient populations.

Study design: Before-after cohort study.

Setting: Patients admitted to two general medical units at a single large academic hospital.

Synopsis: The authors implemented a 12-month multidisciplinary quality improvement project in 3,352 patients, with the goal of mobilizing patients three times per day. Additional goals included consistently documenting daily mobility, setting daily goals to increase activity, and standardizing the description of mobility across disciplines. Ambulation, documentation, and goal setting were assigned to regular nursing staff and targeted at each of the patients admitted to these units during the study period. Highest level of mobility was documented using a locally derived simple eight-point ordinal scale. Daily documentation rate of mobility averaged 85% over the 12 months of the project. Comparing the four-month study period at the beginning of the project implementation to the four-month period after implementation, more patients ambulated (70% versus 43%), patients with improved mobility scores increased from 32% to 45%, and length of stay declined by 0.40 days. All of these differences were statistically significant. There was no increase in falls with injury.

Bottom line: A nurse-driven early mobility program aimed at all patients admitted to general medical services may improve mobility and decrease length of stay.

Clinical question: Given advances in the understanding and treatment of sepsis, can sepsis be better defined?

Background: Definitions of sepsis and septic shock were last revised in 2001. The current definitions are based on a constellation of clinical signs and symptoms in a patient with suspected infection. Recent studies suggest that the definitions have low sensitivity and specificity, and they do not correlate well with patient outcomes.

Study design: Consensus guidelines.

Setting: Task force of 19 critical care, infectious disease, surgical, and pulmonary specialists convened in 2014 by the European Society of Intensive Care Medicine and the Society of Critical Care Medicine.

Synopsis: The task force recommended that sepsis be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection and that it be identified by a change of more than one point in the Sequential Organ Failure Assessment (SOFA) score. This score incorporates the Glasgow Coma Scale, mean arterial blood pressure (MAP), PaO2/FiO2, platelet count, creatinine, and bilirubin. Septic shock is defined as a subset of sepsis with profound circulatory, cellular, and metabolic abnormalities, and it’s identified by serum lactate level >2 mmol/L and vasopressor requirement to maintain a MAP of ≥65 mm Hg in the absence of hypovolemia. These new definitions have higher sensitivity and specificity and can predict mortality more accurately. Patients with these definitions of sepsis and septic shock have in-hospital mortality >10% and >40%, respectively. The presence of two or more quick SOFA (qSOFA) elements (altered mentation, systolic blood pressure ≤100 mm Hg, and respiratory rate ≥22/min) identifies adult patients with suspected infection who need more extensive laboratory testing to exclude sepsis.

Bottom line: Defining sepsis now requires more laboratory testing but provides more diagnostic consistency and more accurately predicts outcomes.
