RESUMEN
OBJECTIVE: The proportion of US emergency department (ED) visits that lead to hospitalization has declined over time. The degree to which advanced imaging use contributed to this trend is unknown. Our objective was to examine the association between advanced imaging use during ED visits and changes in ED hospitalization rates between 2007-2008 and 2015-2016. METHODS: We analyzed data from the National Hospital Ambulatory Medical Care Survey. The primary outcome was ED hospitalization, including admission to inpatient and observation units and outside transfers. The primary exposure was advanced imaging during the ED visit, including computed tomography, magnetic resonance imaging, and ultrasound. We constructed a survey-weighted multivariable logistic regression with binary outcome of ED hospitalization to examine changes in adjusted hospitalization rates from 2007-2008 to 2015-2016, comparing ED visits with and without advanced imaging. RESULTS: ED patients who received advanced imaging (versus those who did not) were more likely to be 65 years or older (25.3% vs 13.0%), non-Hispanic white (65.3% vs 58.5%), female (58.4% vs 54.1%), and have Medicare (26.5% vs 16.0%). Among ED visits with advanced imaging, adjusted annual hospitalization rate declined from 22.5% in 2007-2008 to 17.3% (adjusted risk ratio [aRR] 0.77; 95% CI 0.68, 0.86) in 2015-2016. In the same periods, among ED visits without advanced imaging, adjusted annual hospitalization rate declined from 14.3% to 11.6% (aRR 0.81; 95% CI 0.73, 0.90). The aRRs between ED visits with and without advanced imaging were not significantly different. CONCLUSION: From 2007-2016, ED visits with advanced imaging did not have a greater reduction in admission rate compared to those without advanced imaging. Our results suggest that increasing advanced imaging use likely had a limited role in the general decline in hospital admissions from EDs. Future research is needed to further validate this finding.

OBJECTIVES: We have previously shown that older adults discharged from the emergency department (ED) experience an increased disability burden within a 6-month time period after ED discharge. The objective of this study was to identify risk factors associated with increased disability burden among older adults discharged from the ED. METHODS: This study is part of an ongoing longitudinal study of 754 community-living persons aged ≥70 years. The analytic sample included 813 ED visits without hospitalization from 430 participants who had at least one visit to an ED during a 14-year follow-up period (1998-2012). Information on ED visits and disability burden in 13 functional activities was collected during monthly interviews. Twenty-nine candidate risk factors were evaluated for their independent associations with increased disability burden using a longitudinal multivariable model. RESULTS: In the multivariable analyses, age ≥85 (adjusted risk ratio [aRR] = 1.14, 95% confidence interval [CI] = 1.05 to 1.24), being unmarried (aRR = 1.15, 95% CI = 1.05 to 1.27), lower-extremity weakness (aRR = 1.20, 95% CI = 1.07 to 1.34), and physical frailty (aRR = 1.25, 95% CI = 1.13 to 1.37) were associated with increased disability burden. As the number of risk factors increased, the predicted mean disability burden (on a scale of 0 to 13) also increased, ranging from a value of 1.80 (95% CI = 1.43 to 2.27) for 0 risk factors to a value of 8.59 (95% CI = 7.93 to 9.29) for four risk factors. CONCLUSIONS: Among older adults discharged from the ED, several risk factors were associated with increased disability burden over the following 6 months, including age ≥85, being unmarried, lower-extremity weakness, and physical frailty. Further research is needed to evaluate whether risk stratification based on nonmodifiable factors or interventions targeting modifiable risk factors improve functional outcomes for older adults discharged from the ED.

BACKGROUND: There is an increasing focus in the emergency department (ED) on addressing the needs of persons with cognitive impairment, most of whom have multiple chronic conditions. We investigated which common comorbidities among multimorbid persons with cognitive impairment conferred increased risk for ED treat and release utilization. METHODS: We examined the association of 16 chronic conditions on use of ED treat and release visit utilization among 1006 adults with cognitive impairment andâ¯≥â¯2 comorbidities using the nationally-representative National Health and Aging Trends Study merged with Fee-For-Service Medicare claims data, 2011-2015. RESULTS: At baseline, 28.5% had ≥6 conditions and 35.4% wereâ¯≥â¯85â¯years old. After controlling for sex, age, race, education, urban-living, number of disabled activities of daily living, and sampling strata, we found significantly increased adjusted risk ratios (aRR) of ED treat and release visits for persons with depression (aRR 1.38 95% CI 1.15-1.65) representing 78/100 person-years, and osteoarthritis or rheumatoid arthritis (aRR 1.32 95% CI 1.12-1.57) representing 71/100 person-years. At baseline 93.9% had ≥1 informal caregiver and 69.7% had a caregiver that helped with medications or attended physician visits. CONCLUSION: These results show that multimorbid cognitively impaired older adults with depression or osteoarthritis or rheumatoid arthritis are at higher risk of ED treat and release visits. Future ED research with multimorbid cognitively impaired persons may explore behavioral aspects of depression and/or pain and flairs associated with osteoarthritis or rheumatoid arthritis, as well as the role of informal caregivers in the care of these conditions.

OBJECTIVES: To describe recent trends in advanced imaging and hospitalization of emergency department (ED) syncope patients, both considered "low-value", and examine trend changes before and after the publication of American College Emergency Physician (ACEP) syncope guidelines in 2007, compared to conditions that had no changes in guideline recommendations. METHODS: We analyzed 2002-2015 National Hospital Ambulatory Medical Care Survey data using an interrupted-time series with comparison series design. The primary outcomes were advanced imaging among ED visits with principal diagnosis of syncope and headache and hospitalization for ED visits with principal diagnosis of syncope, chest pain, dysrhythmia, and pneumonia. We adjusted annual imaging and hospitalization rates using survey-weighted multivariable logistic regression, controlling for demographic and visit characteristics. Using adjusted outcomes as datapoints, we compared linear trends and trend changes of annual imaging and hospitalization rates before and after 2007 with aggregate-level multivariable linear regression. RESULTS: From 2002 to 2007, advanced imaging rates for syncope increased from 27.2% to 42.1% but had no significant trend after 2007 (trend change: -3.1%; 95%CI -4.7, -1.6). Hospitalization rates remained at approximately 37% from 2002 to 2007 but declined to 25.7% by 2015 (trend change: -2.2%; 95%CI -3.0, -1.4). Similar trend changes occurred among control conditions versus syncope, including advanced imaging for headache (difference in trend change: -0.6%; 95%CI -2.8, 1.6) and hospitalizations for chest pain, dysrhythmia, and pneumonia (differences in trend changes: 0.1% [95%CI -1.9, 2.0]; -0.9% [95%CI -3.1, 1.3]; and -1.2% [95%CI -5.3, 2.9], respectively). CONCLUSIONS: Before and after the release of 2007 ACEP syncope guidelines, trends in advanced imaging and hospitalization for ED syncope visits had similar changes compared to control conditions. Changes in syncope care may, therefore, reflect broader practice shifts rather than a direct association with the 2007 ACEP guideline. Moreover, utilization of advanced imaging remains prevalent. To reduce low-value care, policymakers should augment society guidelines with additional policy changes such as reportable quality measures.

INTRODUCTION: Routine medical clearance testing of emergency department (ED) patients with acute psychiatric illnesses in the absence of a medical indication has minimal proven utility. Little is known about the variations in clinical practice of ordering medical clearance tests. METHODS: This study was an analysis of data from the annual United States National Hospital Ambulatory Medical Care Survey from 2010 to 2014. The study population was defined as ED visits by patients ≥18years old admitted to a psychiatric facility. We sought to determine the percentage of these ED visits in which at least one medical clearance test was ordered. Using a multivariate logistic regression model, we also evaluated whether patient visit factors or regional variation was associated with use of medical clearance tests. RESULT: A medical clearance test was ordered in 80.4% of ED visits ending with a psychiatric admission. Multivariate logistic regression demonstrated a statistically significant increased odds ratio (OR) of medical clearance testing based on age (OR 1.02, 95%CI 1.01, 1.03), among visits involving an injury or poisoning (OR 2.38, 95%CI 1.54, 3.68), and in the Midwest region as compared to the Northeast region (OR 2.2, 95% confidence interval [CI] 1.09, 4.46), after adjusting for other predictors. DISCUSSION: Our study demonstrated that, on a national level, 4 out of 5 ED visits resulting in a psychiatric facility admission had a medical clearance test ordered. Future research is needed to investigate the reasons underlying the discrepancies in ordering patterns across the U.S., including the effect of local psychiatric admission policies.

STUDY OBJECTIVE: Among older persons, disability and functional decline are associated with increased mortality, institutionalization, and costs. The aim of the study was to determine whether illnesses and injuries leading to an emergency department (ED) visit but not hospitalization are associated with functional decline among community-living older persons. METHODS: From a cohort of 754 community-living older persons who have been followed with monthly interviews for up to 14 years, we matched 813 ED visits without hospitalization (ED only) to 813 observations without an ED visit or hospitalization (control). We compared the course of disability during the following 6 months between the 2 matched groups. To establish a frame of reference, we also compared the ED-only group with an unmatched group who were hospitalized after an ED visit (ED-hospitalized). Disability scores (range 0 [lowest] to 13 [highest]) were compared using generalized linear models adjusted for relevant covariates. Admission to a nursing home and mortality were evaluated as secondary outcomes. RESULTS: The ED-only and control groups were well matched. For both groups, the mean age was 84 years, and 69% were women. The baseline disability scores were 3.4 and 3.6 in the ED-only and control groups, respectively. During the 6-month follow-up period, the ED-only group had significantly higher disability scores than the control group, with an adjusted risk ratio of 1.14 (95% confidence interval [CI] 1.09 to 1.19). Compared with participants in the ED-only group, those who were hospitalized after an ED visit had disability scores that were significantly higher (risk ratio 1.17; 95% CI 1.12 to 1.22). Both nursing home admissions (hazard ratio 3.11; 95% CI 2.05 to 4.72) and mortality (hazard ratio 1.93; 95% CI 1.07 to 3.49) were higher in the ED-only group versus control group during the 6-month follow-up period. CONCLUSION: Although not as debilitating as an acute hospitalization, illnesses and injuries leading to an ED visit without hospitalization were associated with a clinically meaningful decline in functional status during the following 6 months, suggesting that the period after an ED visit represents a vulnerable time for community-living older persons.

BACKGROUND: Canada and the United States have similar medical education systems, but different health care systems. We surveyed medical students in Ontario and California to assess their knowledge and views about health care policy and systems, with an emphasis on attitudes toward universal care. METHODS: A web-based survey was administered during the 2010-2011 academic year to students in 5 medical schools in Ontario and 4 in California. The survey collected demographic data and evaluated attitudes and knowledge regarding broad health care policy issues and health care systems. An index of support for universal health care was created, and logistic regression models were used to examine potential determinants of such support. RESULTS: Responses were received from 2241 students: 1354 from Ontario and 887 from California, representing 42.9% of eligible respondents. Support for universal health care coverage was higher in Ontario (86.8%) than in California (51.1%), p < 0.001. In California, females, self-described nonconservatives, students with the intent to be involved in health care policy as physicians and students with a primary care orientation were associated with support for universal coverage. In Ontario, self-described liberals and accurate knowledge of the Canadian system were associated with support. A single-payer system for practice was preferred by 35.6% and 67.4% of students in California and Ontario, respectively. The quantity of instruction on health care policy in the curriculum was judged too little by 73.1% and 57.5% of students in California and Ontario, respectively. INTERPRETATION: Medical students in Ontario are substantially more supportive of universal access to health care than their California counterparts. A majority of students in both regions identified substantial curricular deficiencies in health care policy instruction.
