Review Comparative Study
Comparison of methods for measuring crowding and its effects on length of stay in the emergency department.
This consensus conference presentation article focuses on methods of measuring crowding. The authors compare daily versus hourly measures, static versus dynamic measures, and the use of linear or logistic regression models versus survival analysis models to estimate the effect of crowding on an outcome. ⋯ Crowding measured at the daily level will mask much of the variation in crowding that occurs within a 24-hour period. ED census at arrival demonstrated similar variation in crowding exposure as time-varying ED census. Discrete time survival analysis is a more appropriate approach for estimating the effect of crowding on an outcome.

System dynamics and dysfunctionalities: levers for overcoming emergency department overcrowding.
Overcrowding of U. S. emergency departments (EDs) is a widely recognized and growing problem. ⋯ It posits that ED overcrowding is actually a symptom of 10 more fundamental problems in U. S. health care and EDs: variations/supply-demand mismatch; primary care provider shortfalls; limited after-hours access; admission throughput challenges; clinical challenges related to discontinuity patients; clinical challenges related to those with special needs; interruptions; testing logistical challenges; suboptimal information systems; and fragmented/dysfunctional health insurance system, leaving many un- and underinsured.

The effect of emergency department (ED) crowding on equitable care is the least studied of the domains of quality as defined by the Institute of Medicine (IOM). Inequities in access and treatment throughout the health care system are well documented in all fields of medicine. ⋯ To design successful interventions, however, it is important to first understand how crowding can result in disparities and base interventions on these mechanisms. A research agenda is proposed to understand mechanisms that may threaten equity during periods of crowding and design and test potential interventions that may ensure the equitable aspect of quality of care.

Over the past decade, emergency departments (ED) have encountered major challenges due to increased crowding and a greater public focus on quality measurement and quality improvement. Responding to these challenges, many EDs have worked to improve their processes and develop new and innovative models of care delivery. Urgent Matters has contributed to ED quality and patient flow improvement by working with hospitals throughout the United States. ⋯ Using a variety of techniques, such as learning networks (collaboratives), national conferences, e-newsletters, webinars, best practices toolkits, and social media, Urgent Matters has served as a thought leader and innovator in ED quality improvement initiatives. The Urgent Matters Seven Success Factors were drawn from the early work done by program participants and propose practical guidelines for implementing and sustaining ED improvement activities. This article chronicles the history, activities, lessons learned, and future of the Urgent Matters program.

In 2011, Academic Emergency Medicine convened a consensus conference entitled "Interventions to Assure Quality in the Crowded Emergency Department." This article, a product of the breakout session on "interventions to safeguard efficiency of care," explores various elements of the research agenda on efficiency and quality in crowded emergency departments (EDs). The authors discuss four areas identified as critical to achieving progress in the research agenda for improving ED efficiency: 1) What measures can be used to understand and improve the efficiency and quality of interventions in the ED? 2) Which factors outside of the ED's control affect ED efficiency? 3) How do workforce factors affect ED efficiency? 4) How do ED design, patient flow structures, and use of technology affect efficiency? Filling these knowledge gaps is vital to identifying interventions that improve the delivery of emergency care in all EDs.
