RESUMO
Fulminant myocarditis (FM) is an uncommon syndrome characterized by sudden and severe diffuse cardiac inflammation often leading to death resulting from cardiogenic shock, ventricular arrhythmias, or multiorgan system failure. Historically, FM was almost exclusively diagnosed at autopsy. By definition, all patients with FM will need some form of inotropic or mechanical circulatory support to maintain end-organ perfusion until transplantation or recovery. Specific subtypes of FM may respond to immunomodulatory therapy in addition to guideline-directed medical care. Despite the increasing availability of circulatory support, orthotopic heart transplantation, and disease-specific treatments, patients with FM experience significant morbidity and mortality as a result of a delay in diagnosis and initiation of circulatory support and lack of appropriately trained specialists to manage the condition. This scientific statement outlines the resources necessary to manage the spectrum of FM, including extracorporeal life support, percutaneous and durable ventricular assist devices, transplantation capabilities, and specialists in advanced heart failure, cardiothoracic surgery, cardiac pathology, immunology, and infectious disease. Education of frontline providers who are most likely to encounter FM first is essential to increase timely access to appropriately resourced facilities, to prevent multiorgan system failure, and to tailor disease-specific therapy as early as possible in the disease process.

Many therapies have been shown to improve outcomes for patients with heart failure (HF) in controlled settings, but there are limited data available to inform best practices for hospital and post-discharge quality improvement initiatives. The CONNECT-HF study is a prospective, cluster-randomized trial of 161 hospitals in the United States with a 2×2 factorial design. The study is designed to assess the effect of a hospital and post-discharge quality improvement intervention compared with usual care (primary objective) on HF outcomes and quality-of-care, as well as to evaluate the effect of hospitals implementing a patient-level digital intervention compared with usual care (secondary objective). The hospital and post-discharge intervention includes audit and feedback on HF clinical process measures and outcomes for patients with HF with reduced ejection fraction (HFrEF) paired with education to sites and clinicians by a trained, nationally representative group of HF and quality improvement experts. The patient-level digital intervention is an optional ancillary study and includes a mobile application and behavioral tools that are intended to facilitate improved use of guideline-directed recommendations for self-monitoring and self-management of activity and medications for HFrEF. The effects of the interventions will be measured through an opportunity-based composite score on quality and time-to-first HF readmission or death among patients with HFrEF who present to study hospitals with acute HF and who consent to participate. The CONNECT-HF study is evaluating approaches for implementing HF guideline recommendations into practice and is one of the largest HF implementation science trials performed to date.

BACKGROUND AND PURPOSE: The diverse causes of right-sided heart failure (RHF) include, among others, primary cardiomyopathies with right ventricular (RV) involvement, RV ischemia and infarction, volume loading caused by cardiac lesions associated with congenital heart disease and valvular pathologies, and pressure loading resulting from pulmonic stenosis or pulmonary hypertension from a variety of causes, including left-sided heart disease. Progressive RV dysfunction in these disease states is associated with increased morbidity and mortality. The purpose of this scientific statement is to provide guidance on the assessment and management of RHF. METHODS: The writing group used systematic literature reviews, published translational and clinical studies, clinical practice guidelines, and expert opinion/statements to summarize existing evidence and to identify areas of inadequacy requiring future research. The panel reviewed the most relevant adult medical literature excluding routine laboratory tests using MEDLINE, EMBASE, and Web of Science through September 2017. The document is organized and classified according to the American Heart Association to provide specific suggestions, considerations, or reference to contemporary clinical practice recommendations. RESULTS: Chronic RHF is associated with decreased exercise tolerance, poor functional capacity, decreased cardiac output and progressive end-organ damage (caused by a combination of end-organ venous congestion and underperfusion), and cachexia resulting from poor absorption of nutrients, as well as a systemic proinflammatory state. It is the principal cause of death in patients with pulmonary arterial hypertension. Similarly, acute RHF is associated with hemodynamic instability and is the primary cause of death in patients presenting with massive pulmonary embolism, RV myocardial infarction, and postcardiotomy shock associated with cardiac surgery. Functional assessment of the right side of the heart can be hindered by its complex geometry. Multiple hemodynamic and biochemical markers are associated with worsening RHF and can serve to guide clinical assessment and therapeutic decision making. Pharmacological and mechanical interventions targeting isolated acute and chronic RHF have not been well investigated. Specific therapies promoting stabilization and recovery of RV function are lacking. CONCLUSIONS: RHF is a complex syndrome including diverse causes, pathways, and pathological processes. In this scientific statement, we review the causes and epidemiology of RV dysfunction and the pathophysiology of acute and chronic RHF and provide guidance for the management of the associated conditions leading to and caused by RHF.

BACKGROUND: Physical examination of jugular venous pressure is used to estimate right atrial (RA) pressure and infer left-sided filling pressure to assist volume management. Previous studies in advanced heart failure patients showed about 75% concordance between RA and pulmonary capillary wedge (PCW) pressures. We sought to determine the relationship between mean RA and mean PCW pressure and assess the clinical significance in a broad population of patients undergoing invasive right heart catheterization (RHC). METHODS: We examined 4135 RHC cases at a single academic medical center from February 2007 to December 2014, analyzing baseline variables, hemodynamic data, and in-hospital mortality. RESULTS: The overall Pearson correlation for mean RA and PCW pressures was 0.68 with 70% concordance between dichotomized pressures (RA ≥10 and PCW ≥22 mmHg). Results were similar in subgroups with heart failure (r=0.67, 72%), STEMI/NSTEMI (r=0.60, 69%), unstable angina (r=0.78, 69%), stable/no angina (r=0.72, 67%), and valvular disease (r=0.61, 72%; Chi-square P=.15). Mean RA pressure was independently associated with in-hospital mortality in multivariate analysis (OR 1.12 [95% CI 1.081-1.157] per 1 mmHg increase, P<.001). The RA/PCW ratio was not independently associated with in-hospital mortality. Mean RA pressure was also weakly associated with worse renal function (rho=-0.16, P<.001). CONCLUSION: In patients undergoing right catheterization for diverse indications, the mean RA and PCW pressures correlated moderately well, but there was discordance in a sizable minority, in whom assessment of left-sided filling pressures using estimated jugular venous pressure may be misleading. Elevated right atrial pressure is a marker for in-hospital mortality.

OBJECTIVE: To characterize a novel "worst"-symptom visual analogue scale (WS-VAS) versus the traditional dyspnea visual analogue scale (DVAS) in an acute heart failure (AHF) trial. BACKGROUND: AHF trials assess symptom relief as a pivotal endpoint with the use of dyspnea scores. However, many AHF patients' worst presenting symptom (WS) may not be dyspnea. We hypothesized that a WS-VAS may reflect clinical improvement better than DVAS in AHF. METHODS AND RESULTS: AHF patients (n = 232) enrolled in the Renal Optimization Strategies Evaluation in Acute Heart Failure (ROSE-AHF) Trial indicated their WS at enrollment and completed DVAS and WS-VAS at enrollment and 24, 48, and 72 hours. Dyspnea was the WS in 61%, body swelling in 29%, and fatigue in 10% of patients. Clinical characteristics differed by WS. In all patients, DVAS scores were higher (less severe symptoms) than WS-VAS and the change in WS-VAS over 72 hours was greater than the change in DVAS (P < .001). Changes in DVAS were smaller in patients with body swelling and fatigue than in patients with dyspnea as their WS (P = .002), whereas changes in the WS-VAS were similar regardless of patients' WS. Neither score, nor its change, was associated with available decongestion markers (change in N-terminal pro-B-type natriuretic peptide, weight or cumulative 72-hour urine volume). CONCLUSIONS: Many AHF patients have symptoms other than dyspnea as their most bothersome symptom. The WS-VAS better reflects symptom improvement across the spectrum of AHF phenotypes. Symptom relief and decongestion were not correlated in this AHF study.

BACKGROUND: Anticipating adverse outcomes guides decisions but can be particularly challenging in heart failure. AIM: We sought to assess the accuracy and comfort of physicians in predicting prognosis in heart failure. DESIGN: Cross-sectional survey PARTICIPANTS/SETTING: Faculty and trainees in internal medicine, cardiology, and oncology estimated survival for three standardized patients: (1) 59-year-old patient with stage IV lung cancer; (2) 79-year-old woman with New York Heart Association class 4 heart failure symptoms and preserved ejection fraction; and (3) 40-year-old man with New York Heart Association class 3 heart failure symptoms and reduced ejection fraction of 20%. Survival predictions were derived from surveillance, epidemiology, and end results-Medicare database and the Seattle Heart Failure Model. Accuracy was defined as <2-fold difference between the clinician and model estimate. RESULTS: Totally, 79% (338/427) of participants responded. Physicians were more accurate in survival estimates for lung cancer than heart failure (74% vs 48%, respectively; p < 0.001). Cardiologists were more accurate in predicting survival in heart failure symptoms and reduced ejection fraction compared to generalists (67% vs 45%; p = 0.005) and oncologists (39%; p = 0.041) but no different at predicting heart failure symptoms and preserved ejection fraction. Cardiologists predicted longer survival in heart failure compared to others (p < 0.05). Physicians felt more uncomfortable discussing palliative care with heart failure patients compared to lung cancer. CONCLUSIONS: Less than half of physicians accurately estimate survival in heart failure. Cardiologists were more accurate than other specialties for heart failure symptoms and reduced ejection fraction but no different for heart failure symptoms and preserved ejection fraction.

BACKGROUND: In the current era, where advanced heart failure (AHF) has become an American Board of Internal Medicine-certified subspecialty, new data are needed to benchmark and value levels of clinical effort performed by AHF specialists (AHFMDs). METHODS AND RESULTS: A 36-question survey was sent to 728 AHFMDs, members of the Heart Failure Society of America, and 224 (31%) responded. Overall, 56% worked in academic medical centers (AMCs) and were younger (48 ± 9 y vs 52 ± 10 y; P < .01) and were represented by a higher proportion of women (34% vs 21%, P < .01) compared with non-AMCs. The percentage of time in clinical care was lower in AMCs (64 ± 19% vs 78 ± 18%; P = .002), with similar concentration on evaluation and management services (79 ± 18% in AMCs vs 72 ± 18 % in non-AMCs; P = NS). The majority of nonclinical time was spent in program administration (10% in both AMCs and non-AMCs) and education/research (15% in AMC vs 5% in non-AMCs). Although 69% of respondents were compensated by work-relative value units (wRVUs), only a small percentage knew their target or the amount of RVUs generated. The mean annual wRVUs generated were lower in AMCs compared to non-AMCs (5,452 ± 1,961 vs 9,071 ± 3,484; P < .001). The annual compensation in AMCs was lower than in non-AMCs (45% vs 10% <$250,000 and 17% vs 61% >$350,000; P < .001) and the satisfaction with compensation was higher in non-AMCs. CONCLUSIONS: AHFMDs' compensation is largely dependent by practice type (AMC vs non-AMC) and clinical productivity as measured by wRVUs. These data provide an opportunity for benchmarking work effort and compensation for AHFMDs, allowing distinction from segments of cardiologists with greater opportunity to accrue procedural wRVUs. They also show several differences between AMCs and non-AMCs that should be considered when formulating work assignment and compensation for AHFMDs.

Heart failure readmissions result in significant costs to the health care system and to patients' quality of life, but programs to reduce readmissions have met with mixed success. Successful strategies have included multidisciplinary hospital-based quality initiatives, disease management programs, and care transition interventions. Devices like telemonitors and indwelling catheters, however, have met with mixed success. Research is still needed to elucidate the most effective interventions for readmission reduction in the HF population.

BACKGROUND: Hospitals are challenged to reduce length of stay (LOS), yet simultaneously reduce readmissions for patients with heart failure (HF). This study investigates whether 30-day rehospitalization or an alternative measure of total inpatient days over an episode of care (EOC) is the best indicator of resource use, HF quality, and outcomes. METHODS: Using data from the American Heart Association's Get With The Guidelines-Heart Failure Registry linked to Medicare claims, we ranked and compared hospitals by LOS, 30-day readmission rate, and overall EOC metric, defined as all hospital days for an HF admission and any subsequent admissions within 30 days. We divided hospitals into quartiles by 30-day EOC and 30-day readmission rates. We compared performance by EOC and readmission rate quartiles with respect to quality of care indicators and 30-day postdischarge mortality. RESULTS: The population had a mean age of 80 ± 7.95 years, 45% were male, and 82% were white. Hospital-level unadjusted median index LOS and overall EOC were 4.9 (4.2-5.6) and 6.2 (5.3-7.4) days, respectively. Median 30-day readmission rate was 23.2%. Hospital HF readmission rate was not associated with initial hospital LOS, only slightly associated with total EOC rank (r = 0.26, P = .001), and inversely related to HF performance measures. After adjustment, there was no association between 30-day readmission and decreased 30-day mortality. In contrast, better performance on the EOC metric was associated with decreased odds of 30-day mortality. CONCLUSIONS: Although hospital 30-day readmission rate was poorly correlated with LOS, quality measures, and 30-day mortality, better performance on the EOC metric was associated with better 30-day survival. Total inpatient days during a 30-day EOC may more accurately reflect overall resource use and better serve as a target for quality improvement efforts.

BACKGROUND: Patients with heart failure are at higher risk for thromboembolic events, even in the absence of atrial fibrillation, but the effect of anticoagulation therapy on outcomes is uncertain. METHODS AND RESULTS: With data from a clinical registry linked to Medicare claims, we estimated the adjusted associations between anticoagulation and 1-year outcomes with the use of inverse probability of treatment weighting. Eligible patients had an ejection fraction ≤35%, had no concurrent atrial fibrillation, were alive at discharge, and had not received anticoagulation therapy before admission. Of 13,217 patients in 276 hospitals, 1,140 (8.6%) received anticoagulation therapy at discharge. Unadjusted rates of thromboembolic events and major adverse cardiovascular events did not differ by receipt of anticoagulation therapy. Patients discharged on anticoagulation therapy had lower unadjusted rates of all-cause mortality (27.2% vs 32.3%; P < .001) and readmission for heart failure (29.4% vs 35.4%; P < .001) and higher rates of bleeding events (5.2% vs 2.8%; P < .001). After adjustment for probability of treatment and discharge medications, there were no differences in all-cause mortality (hazard ratio 0.92; 95% confidence interval 0.80-1.06) or readmission for heart failure (0.91, 0.81-1.02), but patients receiving anticoagulation therapy were at higher risk for bleeding events (2.09, 1.47-2.97). CONCLUSIONS: Anticoagulation therapy at discharge is infrequent among older patients with heart failure and without atrial fibrillation. There were no statistically significant propensity-weighted associations between anticoagulation therapy and 1-year outcomes, except for a higher risk of bleeding.

BACKGROUND: Patients hospitalized with heart failure (HF) have elevated B-type natriuretic peptide (BNP) levels and increased risk for thromboembolic events. Associations between BNP level and thromboembolic events in patients with HF without atrial fibrillation (AF) are not well studied. METHODS: We linked data from the ADHERE registry for 2003 through 2006 with Medicare claims to identify patients ≥65 years who were hospitalized with HF, did not have AF, and did not receive warfarin at discharge. We estimated rates of all-cause mortality, thromboembolic events, myocardial infarction (MI), and stroke using Kaplan-Meier methods and the cumulative incidence function. We used Cox models to assess associations between log BNP level and each outcome after adjustment for potential confounders. RESULTS: The study population included 11,679 patients from 146 sites. Patients in the highest quartile of BNP level were older and more often male and African American. They had higher rates of coronary artery disease, renal insufficiency, and peripheral vascular disease and lower rates of diabetes mellitus and chronic obstructive pulmonary disease. After multivariable adjustment, each 30% increase in BNP level was associated with increased risks of death (hazard ratio 1.07, 95% CI 1.05-1.08) and MI (1.07, 1.04-1.10) but not thromboembolism or stroke. CONCLUSION: Higher BNP level upon admission with HF among older patients without AF was associated with increased risks of MI and mortality; however, higher BNP level was not associated with subsequent thromboembolism or stroke.

BACKGROUND: Heart failure (HF) is a leading cause of hospitalization. Although a number of multicenter international HF hospital registries have been published, there are limited data for the Asia Pacific region. METHODS: ADHERE (ie, Acute Decompensated Heart Failure Registry) International-Asia Pacific is an electronic web-based observational database of 10,171 patients hospitalized with a principal diagnosis of HF from 8 Asia-Pacific countries between January 2006 and December 2008. RESULTS: The median age (67 years) varied by more than 2 decades across the region. Fifty-seven percent of patients were male. Ninety percent of patients were Asian and 8.4% were white. Dyspnea was the presenting symptom in 95%, with 80% having documented rales. During the index hospitalization, left ventricular function was assessed in 50%, and intravenous therapies included diuretics (85%), vasodilators (14%), and positive inotropes (15%). In-hospital mortality was 4.8%. Discharge medications included angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers (63%), ß-blockers (41%), and aldosterone antagonists (31%). CONCLUSIONS: Compared with other multicenter registries, patients hospitalized with acute HF in the Asia Pacific region tend to present with more severe clinical symptoms and signs and are younger, especially in countries at an earlier stage in their epidemiological transition. Echocardiography and disease-modifying medications are used less often, highlighting potential opportunities to improve outcomes.

CONTEXT: ST-segment elevation myocardial infarction (STEMI) treatment has improved outcomes and shortened hospital stay. Recently, 30-day readmission rates have been proposed as a metric for care of patients with STEMI. However, international rates and predictors of 30-day readmission after STEMI have not been studied. OBJECTIVE: To determine international variation in and predictors of 30-day readmission rates after STEMI and country-level care patterns. DESIGN, SETTING, AND PATIENTS: Post hoc analysis of the Assessment of Pexelizumab in Acute Myocardial Infarction trial that enrolled 5745 patients with STEMI at 296 sites in the United States, Canada, Australia, New Zealand, and 13 European countries from July 13, 2004, to May 11, 2006. Multivariable logistic regression analysis was used to identify independent predictors of all-cause and nonelective 30-day postdischarge readmission. MAIN OUTCOME MEASURES: Predictors of 30-day postdischarge all-cause and nonelective readmissions. RESULTS: Of 5571 patients with STEMI who survived to hospital discharge, 631 (11.3%) were readmitted within 30 days. Thirty-day readmission rates were higher for the United States than other countries (14.5% vs 9.9%; P < .001). Median length of stay was shortest for US patients (3 days; interquartile range, 2-4 days) and longest for Germany (8 days; interquartile range, 6-11 days). In multivariable regression, the predictors of 30-day readmission included multivessel disease (odds ratio [OR], 1.97; 95% CI, 1.65-2.35) and US location (OR, 1.68; 95% CI, 1.37-2.07). Excluding elective readmission for revascularization, US enrollment was still an independent predictor of readmission (OR, 1.53; 95% CI, 1.20-1.96). After adjustment of the models for country-level median length of stay, US location was no longer an independent predictor of 30-day all-cause or nonelective readmission. Location in the United States was not a predictor of in-hospital death (OR, 0.88; 95% CI, 0.60-1.30) or 30-day postadmission death (OR, 1.0; 95% CI, 0.72-1.39). CONCLUSIONS: In this multinational study, there was variation across countries in 30-day readmission rates after STEMI, with readmission rates higher in the United States than in other countries. However, this difference was greatly attenuated after adjustment for length of stay.

BACKGROUND: Clinical registries are used increasingly to analyze quality and outcomes, but the generalizability of findings from registries is unclear. METHODS: We linked data from the Acute Decompensated Heart Failure National Registry (ADHERE) to 100% fee-for-service Medicare claims data. We compared patient characteristics and inpatient mortality of linked and unlinked ADHERE hospitalizations; patient characteristics, readmission, and postdischarge mortality of linked ADHERE patients to a random 20% sample of Medicare beneficiaries hospitalized for heart failure; and characteristics of Medicare sites participating and not participating in ADHERE. RESULTS: Among 135,667 ADHERE records for eligible patients ≥ 65 years, we matched 104,808 (77.3%) records to fee-for-service Medicare claims, representing 82,074 patients. Linked hospitalizations were more likely than unlinked hospitalizations to involve women and white patients; there were no meaningful differences in other patient characteristics. In-hospital mortality was identical for linked and unlinked hospitalizations. In Medicare, ADHERE patients had slightly lower unadjusted mortality (4.4% vs 4.9% in-hospital, 11.2% vs 12.2% at 30 days, 36.0% vs 38.3% at 1 year [P < .001]) and all-cause readmission (22.1% vs 23.7% at 30 days, 65.8% vs 67.9% at 1 year [P < .001]). After risk adjustment, modest but statistically significant differences remained. ADHERE hospitals were more likely than non-ADHERE hospitals to be teaching hospitals, have higher volumes of heart failure discharges, and offer advanced cardiac services. CONCLUSION: Elderly patients in ADHERE are similar to Medicare beneficiaries hospitalized with heart failure. Differences related to selective enrollment in ADHERE hospitals and self-selection of participating hospitals are modest.

OBJECTIVES: This study sought to determine the frequency, incidence rates over time, association with mortality, and potential risk factors for hemocompatibility-related adverse events (HRAEs) occurring during venoarterial-extracorporeal life support (VA-ECLS). BACKGROUND: HRAEs are common complications of VA-ECLS. Studies examining relevant clinical predictors and the association of HRAEs with survival are limited by small sample size and single-center setting. METHODS: We queried adult patients supported with VA-ECLS from 2010 to 2017 in the Extracorporeal Life Support Organization database to assess the impact of HRAEs on in-hospital mortality. RESULTS: Among 11,984 adults meeting study inclusion, 8,457 HRAEs occurred; 62.1% were bleeding events. The HRAE rate decreased significantly over the study period (p trend <0.001), but rates of medical bleeding and ischemic stroke remained stable. HRAEs had a cumulative association with mortality in adjusted analysis: 1 event, odds ratio (OR) of 1.43; 2 events, OR of 1.86; ≥3 events, OR of 3.27 (p < 0.001 for all). HRAEs most strongly associated with mortality were medical bleeding, including intracranial (OR: 7.71), pulmonary (OR: 3.08), and gastrointestinal (OR: 1.95) hemorrhage and ischemic stroke (OR: 2.31); p < 0.001 for all. Risk factors included the following: for bleeding: older age, lower pH, and female sex; for thrombosis: younger age, male sex, Asian race, and non-polymethylpentene oxygenator; and for both: time on ECLS, central cannulation, and renal failure. CONCLUSIONS: Although decreasing, HRAEs remain common during VA-ECLS and have a cumulative association with survival. Bleeding events are twice as common as thrombotic events, with a hierarchy of HRAEs influencing survival. Differential risk factors for bleeding and thrombotic complications exist and raise the possibility of a tailored approach to ECLS management.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO)-also referred to as extracorporeal life support-is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange. The initiation of VA-ECMO has emerged as a salvage intervention in patients with cardiogenic shock, even cardiac arrest refractory to standard therapies. Analogous to veno-venous ECMO for acute respiratory failure, VA-ECMO provides circulatory support and allows time for other treatments to promote recovery or may be a bridge to a more durable mechanical solution in the setting of acute or acute on chronic cardiopulmonary failure. In this review, we provide a brief overview of VA-ECMO, the attendant physiological considerations of peripheral VA-ECMO, and its complications, namely that of left ventricular distention, bleeding, heightened systemic inflammatory response syndrome, thrombosis and thromboembolism, and extremity ischemia or necrosis.

BACKGROUND: Early ambulation (EA) is associated with improved outcomes for mechanically ventilated and stroke patients. Whether the same association exists for patients hospitalized with acute heart failure is unknown. We sought to determine whether EA among patients hospitalized with heart failure is associated with length of stay, discharge disposition, 30-day post discharge readmissions, and mortality. METHODS AND RESULTS: The study population included 369 hospitals and 285 653 patients with heart failure enrolled in the Get With The Guidelines-Heart Failure registry. We used multivariate logistic regression with generalized estimating equations at the hospital level to identify predictors of EA and determine the association between EA and outcomes. Sixty-five percent of patients ambulated by day 2 of the hospital admission. Patient-level predictors of EA included younger age, male sex, and hospitalization outside of the Northeast (P<0.01 for all). Hospital size and academic status were not predictive. Hospital-level analysis revealed that those hospitals with EA rates in the top 25% were less likely to have a long length of stay (defined as >4 days) compared with those in the bottom 25% (odds ratio, 0.83; confidence interval, 0.73-0.94; P=0.004). Among a subgroup of fee-for-service Medicare beneficiaries, we found that hospitals in the highest quartile of rates of EA demonstrated a statistically significant 24% lower 30-day readmission rates (P<0.0001). Both end points demonstrated a dose-response association and statistically significant P for trend test. CONCLUSIONS: Multivariable-adjusted hospital-level analysis suggests an association between EA and both shorter length of stay and lower 30-day readmissions. Further prospective studies are needed to validate these findings.
