The emergency department (ED) is now the primary source for hospitalizations in the United States, and admission rates for all causes differ widely between EDs. In this study we used a national sample of ED visits to examine variation in risk-standardized hospital admission rates from EDs and the relationship of this variation to inpatient mortality for the fifteen most commonly admitted medical and surgical conditions. We then estimated the impact of variation on national health expenditures under different utilization scenarios. Risk-standardized admission rates differed substantially across EDs, ranging from 1.03-fold for sepsis to 6.55-fold for chest pain between the twenty-fifth and seventy-fifth percentiles of the visits. Conditions such as chest pain, soft tissue infection, asthma, chronic obstructive pulmonary disease, and urinary tract infection were low-mortality conditions that showed the greatest variation. This suggests that some of these admissions might not be necessary, thus representing opportunities to improve efficiency and reduce health spending. Our data indicate that there may be sizeable savings to US payers if differences in ED hospitalization practices could be narrowed among a few of these high-variation, low-mortality conditions.

IMPORTANCE Unscheduled short-term return visits to the emergency department (ED) are increasingly monitored as a hospital performance measure and have been proposed as a measure of the quality of emergency care. OBJECTIVE To examine in-hospital clinical outcomes and resource use among patients who are hospitalized during an unscheduled return visit to the ED. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of adult ED visits to acute care hospitals in Florida and New York in 2013 using data from the Healthcare Cost and Utilization Project. Patients with index ED visits were identified and followed up for return visits to the ED within 7, 14, and 30 days. EXPOSURES Hospital admission occurring during an initial visit to the ED vs during a return visit to the ED. MAIN OUTCOMES AND MEASURES In-hospital mortality, intensive care unit (ICU) admission, length of stay, and inpatient costs. RESULTS Among the 9,036,483 index ED visits to 424 hospitals in the study sample, 1,758,359 patients were admitted to the hospital during the index ED visit. Of these patients, 149,214 (8.5%) had a return visit to the ED within 7 days of the index ED visit, 228,370 (13.0%) within 14 days, and 349,335 (19.9%) within 30 days, and 76,151 (51.0%), 122,040 (53.4%), and 190,768 (54.6%), respectively, were readmitted to the hospital. Among the 7,278,124 patients who were discharged during the index ED visit, 598,404 (8.2%) had a return visit to the ED within 7 days, 839,386 (11.5%) within 14 days, and 1,205,865 (16.6%) within 30 days. Of these patients, 86,012 (14.4%) were admitted to the hospital within 7 days, 121,587 (14.5%) within 14 days, and 173,279 (14.4%) within 30 days. The 86,012 patients discharged from the ED and admitted to the hospital during a return ED visit within 7 days had significantly lower rates of in-hospital mortality (1.85%) compared with the 1,609,145 patients who were admitted during the index ED visit without a return ED visit (2.48%) (odds ratio, 0.73 [95% CI, 0.69-0.78]), lower rates of ICU admission (23.3% vs 29.0%, respectively; odds ratio, 0.73 [95% CI, 0.71-0.76]), lower mean costs (

781]), and longer lengths of stay (5.16 days vs 4.97 days; IRR, 1.04 [95% CI, 1.03-1.05]). Similar outcomes were observed for patients returning to the ED within 14 and 30 days of the index ED visit. In contrast, patients who returned to the ED after hospital discharge and were readmitted had higher rates of in-hospital mortality and ICU admission, longer lengths of stay, and higher costs during the repeat hospital admission compared with those admitted to the hospital during the index ED visit without a return ED visit. CONCLUSIONS AND RELEVANCE Compared with adult patients who were hospitalized during the index ED visit and did not have a return visit to the ED, patients who were initially discharged during an ED visit and admitted during a return visit to the ED had lower in-hospital mortality, ICU admission rates, and in-hospital costs and longer lengths of stay. These findings suggest that hospital admissions associated with return visits to the ED may not adequately capture deficits in the quality of care delivered during an ED visit.

STUDY OBJECTIVE Although numerous studies have demonstrated a relationship between higher volume and improved outcomes in the delivery of health services, it has not been extensively explored in the emergency department (ED) setting. Therefore, we seek to examine the association between ED hospitalization volume and mortality for common high-risk conditions. METHODS Using data from the Nationwide Inpatient Sample, a national sample of hospital discharges, we evaluated mortality overall and for 8 different diagnoses between 2005 and 2009 (total admissions 17.55 million). These conditions were chosen because they are frequent (in the top 25 of all ED hospitalizations) and high risk (> 3% observed mortality). EDs were excluded from analysis if they did not have at least 1,000 total annual admissions and 30 disease-specific cases. EDs were then placed into quintiles based on hospitalized volume. Regression techniques were used to describe the relationship between volume (number of hospitalized ED patients per year) and both subsequent early inpatient mortality (within 2 days of admission) and overall mortality, adjusted for patient and hospital characteristics. RESULTS Mortality decreased as volume increased overall and for all diagnoses, but the relative importance of volume varied, depending on the condition. Absolute differences in adjusted mortality rates between very high-volume EDs and very low-volume EDs ranged from -5.6% for sepsis (95% confidence interval [CI] -6.5% to -4.7%) to -0.2% for pneumonia (95% CI -0.6% to 0.1%). Overall, this difference was -0.4% (95% CI -0.6% to -0.3%). A similar pattern was observed when early hospital deaths were evaluated. CONCLUSION Patients have a lower likelihood of inhospital death if admitted through high-volume EDs.

ABSTRACTBACKGROUNDPhysicians have dual responsibilities to make medical decisions that serve their patients’ best interests but also utilize health care resources wisely. Their ability to practice cost-consciously is particularly challenged when faced with patient expectations or requests for medical services that may be unnecessary.OBJECTIVETo understand how physicians consider health care resources and the strategies they use to exercise cost-consciousness in response to patient expectations and requests for medical care.DESIGNExploratory, qualitative focus groups of practicing physicians were conducted. Participants were encouraged to discuss their perceptions of resource constraints, and experiences with redundant, unnecessary and marginally beneficial services, and were asked about patient requests or expectations for particular services.PARTICIPANTSSixty-two physicians representing a variety of specialties and practice types participated in nine focus groups in Michigan, Ohio, and Minnesota in 2012MEASUREMENTSIterative thematic content analysis of focus group transcriptsPRINCIPAL FINDINGSPhysicians reported making trade-offs between a variety of financial and nonfinancial resources, considering not only the relative cost of medical decisions and alternative services, but the time and convenience of patients, their own time constraints, as well as the logistics of maintaining a successful practice. They described strategies and techniques to educate patients, build trust, or substitute less costly alternatives when appropriate, often adapting their management to the individual patient and clinical environment.CONCLUSIONSPhysicians often make nuanced trade-offs in clinical practice aimed at efficient resource use within a complex flow of clinical work and patient expectations. Understanding the challenges faced by physicians and the strategies they use to exercise cost-consciousness provides insight into policy measures that will address physician’s roles in health care resource use.
