Study objective Emergency department (ED) crowding is a prevalent health delivery problem and may adversely affect the outcomes of patients requiring admission. We assess the association of ED ...crowding with subsequent outcomes in a general population of hospitalized patients. Methods We performed a retrospective cohort analysis of patients admitted in 2007 through the EDs of nonfederal, acute care hospitals in California. The primary outcome was inpatient mortality. Secondary outcomes included hospital length of stay and costs. ED crowding was established by the proxy measure of ambulance diversion hours on the day of admission. To control for hospital-level confounders of ambulance diversion, we defined periods of high ED crowding as those days within the top quartile of diversion hours for a specific facility. Hierarchic regression models controlled for demographics, time variables, patient comorbidities, primary diagnosis, and hospital fixed effects. We used bootstrap sampling to estimate excess outcomes attributable to ED crowding. Results We studied 995,379 ED visits resulting in admission to 187 hospitals. Patients who were admitted on days with high ED crowding experienced 5% greater odds of inpatient death (95% confidence interval CI 2% to 8%), 0.8% longer hospital length of stay (95% CI 0.5% to 1%), and 1% increased costs per admission (95% CI 0.7% to 2%). Excess outcomes attributable to periods of high ED crowding included 300 inpatient deaths (95% CI 200 to 500 inpatient deaths), 6,200 hospital days (95% CI 2,800 to 8,900 hospital days), and $17 million (95% CI $11 to $23 million) in costs. Conclusion Periods of high ED crowding were associated with increased inpatient mortality and modest increases in length of stay and costs for admitted patients.
This article revisits the persistent problem of crowding in US hospital emergency departments (EDs). It begins with a brief review of origins of this problem, terms used to refer to ED crowding, ...proposed definitions and measures of crowding, and causal factors. The article then summarizes recent studies that document adverse moral consequences of ED crowding, including poorer patient outcomes; increased medical errors; compromises in patient physical privacy, confidentiality, and communication; and provider moral distress. It describes several organizational strategies implemented to relieve crowding and implications of ED crowding for individual practitioners. The article concludes that ED crowding remains a morally significant problem and calls on emergency physicians, ED and hospital leaders, emergency medicine professional associations, and policymakers to collaborate on solutions.
The coronavirus disease 2019 (COVID-19) pandemic, associated mitigation measures, and social and economic impacts may affect mental health, suicidal behavior, substance use, and violence.
To examine ...changes in US emergency department (ED) visits for mental health conditions (MHCs), suicide attempts (SAs), overdose (OD), and violence outcomes during the COVID-19 pandemic.
This cross-sectional study used data from the Centers for Disease Control and Prevention's National Syndromic Surveillance Program to examine national changes in ED visits for MHCs, SAs, ODs, and violence from December 30, 2018, to October 10, 2020 (before and during the COVID-19 pandemic). The National Syndromic Surveillance Program captures approximately 70% of US ED visits from more than 3500 EDs that cover 48 states and Washington, DC.
Outcome measures were MHCs, SAs, all drug ODs, opioid ODs, intimate partner violence (IPV), and suspected child abuse and neglect (SCAN) ED visit counts and rates. Weekly ED visit counts and rates were computed overall and stratified by sex.
From December 30, 2018, to October 10, 2020, a total of 187 508 065 total ED visits (53.6% female and 46.1% male) were captured; 6 018 318 included at least 1 study outcome (visits not mutually exclusive). Total ED visit volume decreased after COVID-19 mitigation measures were implemented in the US beginning on March 16, 2020. Weekly ED visit counts for all 6 outcomes decreased between March 8 and 28, 2020 (March 8: MHCs = 42 903, SAs = 5212, all ODs = 14 543, opioid ODs = 4752, IPV = 444, and SCAN = 1090; March 28: MHCs = 17 574, SAs = 4241, all ODs = 12 399, opioid ODs = 4306, IPV = 347, and SCAN = 487). Conversely, ED visit rates increased beginning the week of March 22 to 28, 2020. When the median ED visit counts between March 15 and October 10, 2020, were compared with the same period in 2019, the 2020 counts were significantly higher for SAs (n = 4940 vs 4656, P = .02), all ODs (n = 15 604 vs 13 371, P < .001), and opioid ODs (n = 5502 vs 4168, P < .001); counts were significantly lower for IPV ED visits (n = 442 vs 484, P < .001) and SCAN ED visits (n = 884 vs 1038, P < .001). Median rates during the same period were significantly higher in 2020 compared with 2019 for all outcomes except IPV.
These findings suggest that ED care seeking shifts during a pandemic, underscoring the need to integrate mental health, substance use, and violence screening and prevention services into response activities during public health crises.
As coronavirus disease 2019 (COVID-19) spread throughout the US in the early months of 2020, acute care delivery changed to accommodate an influx of patients with a highly contagious infection about ...which little was known.
To examine trends in emergency department (ED) visits and visits that led to hospitalizations covering a 4-month period leading up to and during the COVID-19 outbreak in the US.
This retrospective, observational, cross-sectional study of 24 EDs in 5 large health care systems in Colorado (n = 4), Connecticut (n = 5), Massachusetts (n = 5), New York (n = 5), and North Carolina (n = 5) examined daily ED visit and hospital admission rates from January 1 to April 30, 2020, in relation to national and the 5 states' COVID-19 case counts.
Time (day) as a continuous variable.
Daily counts of ED visits, hospital admissions, and COVID-19 cases.
A total of 24 EDs were studied. The annual ED volume before the COVID-19 pandemic ranged from 13 000 to 115 000 visits per year; the decrease in ED visits ranged from 41.5% in Colorado to 63.5% in New York. The weeks with the most rapid rates of decrease in visits were in March 2020, which corresponded with national public health messaging about COVID-19. Hospital admission rates from the ED were stable until new COVID-19 case rates began to increase locally; the largest relative increase in admission rates was 149.0% in New York, followed by 51.7% in Massachusetts, 36.2% in Connecticut, 29.4% in Colorado, and 22.0% in North Carolina.
From January through April 2020, as the COVID-19 pandemic intensified in the US, temporal associations were observed with a decrease in ED visits and an increase in hospital admission rates in 5 health care systems in 5 states. These findings suggest that practitioners and public health officials should emphasize the importance of visiting the ED during the COVID-19 pandemic for serious symptoms, illnesses, and injuries that cannot be managed in other settings.
Study objective We evaluate recent trends in emergency department (ED) crowding and its potential causes by analyzing ED occupancy, a proxy measure for ED crowding. Methods We analyzed data from the ...annual National Hospital Ambulatory Medical Care Surveys from 2001 to 2008. The surveys abstract patient records from a national sample of hospital EDs to generate nationally representative estimates of visits. We used time of ED arrival and length of ED visit to calculate mean and hourly ED occupancy. Results During the 8-year study period, the number of ED visits increased by 1.9% per year (95% confidence interval 1.2% to 2.5%), a rate 60% faster than population growth. Mean occupancy increased even more rapidly, at 3.1% per year (95% confidence interval 2.3% to 3.8%), or 27% during the 8 study years. Among potential factors associated with crowding, the use of advanced imaging increased most, by 140%. But advanced imaging had a smaller effect on the occupancy trend than other more common throughput factors, such as the use of intravenous fluids and blood tests, the performance of any clinical procedure, and the mention of 2 or more medications. Of patient characteristics, Medicare payer status and the age group 45 to 64 years accounted for small disproportionate increases in occupancy. Conclusion Despite repeated calls for action, ED crowding is getting worse. Sociodemographic changes account for some of the increase, but practice intensity is the principal factor driving increasing occupancy levels. Although hospital admission generated longer ED stays than any other factor, it did not influence the steep trend in occupancy.
The National Pediatric Readiness Project is a US initiative to improve emergency department (ED) readiness to care for acutely ill and injured children. However, it is unclear whether high ED ...pediatric readiness is associated with improved survival in US trauma centers.
To evaluate the association between ED pediatric readiness, in-hospital mortality, and in-hospital complications among injured children presenting to US trauma centers.
A retrospective cohort study of 832 EDs in US trauma centers in 50 states and the District of Columbia was conducted using data from January 1, 2012, through December 31, 2017. Injured children younger than 18 years who were admitted, transferred, or with injury-related death in a participating trauma center were included in the analysis. Subgroups included children with an Injury Severity Score (ISS) of 16 or above, indicating overall seriously injured (accounting for all injuries); any Abbreviated Injury Scale (AIS) score of 3 or above, indicating at least 1 serious injury; a head AIS score of 3 or above, indicating serious brain injury; and need for early use of critical resources.
Emergency department pediatric readiness for the initial ED visit, measured through the weighted Pediatric Readiness Score (range, 0-100) from the 2013 National Pediatric Readiness Project ED pediatric readiness assessment.
In-hospital mortality, with a secondary composite outcome of in-hospital mortality or complication. For the primary measurement tools used, the possible range of the AIS is 0 to 6, with 3 or higher indicating a serious injury; the possible range of the ISS is 0 to 75, with 16 or higher indicating serious overall injury. The weighted Pediatric Readiness Score examines and scores 6 domains; in this study, the lowest quartile included scores of 29 to 62 and the highest quartile included scores of 93 to 100.
There were 372 004 injured children (239 273 64.3% boys; median age, 10 years interquartile range, 4-15 years), including 5700 (1.5%) who died in-hospital and 5018 (1.3%) who developed in-hospital complications. Subgroups included 50 440 children (13.6%) with an ISS of 16 or higher, 124 507 (33.5%) with any AIS score of 3 or higher, 57 368 (15.4%) with a head AIS score of 3 or higher, and 32 671 (8.8%) requiring early use of critical resources. Compared with EDs in the lowest weighted Pediatric Readiness Score quartile, children cared for in the highest ED quartile had lower in-hospital mortality (adjusted odds ratio aOR, 0.58; 95% CI, 0.45-0.75), but not fewer complications (aOR for the composite outcome 0.88; 95% CI, 0.74-1.04). These findings were consistent across subgroups, strata, and multiple sensitivity analyses. If all children cared for in the lowest-readiness quartiles (1-3) were treated in an ED in the highest quartile of readiness, an additional 126 lives (95% CI, 97-154 lives) might be saved each year in these trauma centers.
In this cohort study, injured children treated in high-readiness EDs had lower mortality compared with similar children in low-readiness EDs, but not fewer complications. These findings support national efforts to increase ED pediatric readiness in US trauma centers that care for children.
Background: An Institute of Medicine (IOM) report defines six domains of quality of care: safety, patient‐centeredness, timeliness, efficiency, effectiveness, and equity. The effect of emergency ...department (ED) crowding on these domains of quality has not been comprehensively evaluated.
Objectives: The objective was to review the medical literature addressing the effects of ED crowding on clinically oriented outcomes (COOs).
Methods: We reviewed the English‐language literature for the years 1989–2007 for case series, cohort studies, and clinical trials addressing crowding’s effects on COOs. Keywords searched included “ED crowding,”“ED overcrowding,”“mortality,”“time to treatment,”“patient satisfaction,”“quality of care,” and others.
Results: A total of 369 articles were identified, of which 41 were kept for inclusion. Study quality was modest; most articles reflected observational work performed at a single institution. There were no randomized controlled trials. ED crowding is associated with an increased risk of in‐hospital mortality, longer times to treatment for patients with pneumonia or acute pain, and a higher probability of leaving the ED against medical advice or without being seen. Crowding is not associated with delays in reperfusion for patients with ST‐elevation myocardial infarction. Insufficient data were available to draw conclusions on crowding’s effects on patient satisfaction and other quality endpoints.
Conclusions: A growing body of data suggests that ED crowding is associated both with objective clinical endpoints, such as mortality, as well as clinically important processes of care, such as time to treatment for patients with time‐sensitive conditions such as pneumonia. At least two domains of quality of care, safety and timeliness, are compromised by ED crowding.
Our study reviewed the empirical evidence on the utilization of health care services by migrants in Europe, and on differences in health service utilization between migrants and non-migrants across ...European countries.
A systematic literature review was performed, searching the databases Medline, Cinahl and Embase and covering the period from January 2009 to April 2016. The final number of articles included was 39.
Utilization of accident and emergency services and hospitalizations were higher among migrants compared with non-migrants in most countries for which evidence was available. In contrast, screening and outpatient visits for specialized care were generally used less often by migrants.
Utilization of general practitioner services among migrants compared with non-migrants presents a diverging picture.
Compared with previous systematic reviews, the results indicate a clearer picture of the differences in health service utilization between migrants and non-migrants in Europe.
A comprehensive comparison across European countries is impossible because the number of studies is still limited. Further research should also help to identify barriers regarding the utilization of health care services by migrants.
