Improving Capacity Management in the Emergency Department: A Review of the Literature, 2000-2012.

Capacity management (CM) is a critical component of maintaining and improving healthcare quality and patient safety. One particular area for concern has been the emergency department and the growing issues of patient overcrowding, boarding, and ambulance diversion, which can result in poor patient care and less efficient operations. This study provides a review of the current and most relevant academic literature on capacity management directly related to hospital emergency departments, identifies strengths and weaknesses of the approaches discussed in the literature, and provides practical recommendations for health services administrators implementing CM in their organizations. An extensive literature search was conducted using several search engines and scholarly databases. Articles were identified based on a combination of keywords and then were reviewed and selected for inclusion in the study in adherence to specified criteria. The CM literature includes a great divergence of themes, topics, and definitions. Twenty-two articles were selected for their relevance to emergency department CM with a focus on operations management concepts. A categorization scheme was used, resulting in four thematic groups of articles: problems, solutions, outcomes, and metrics. Healthcare managers wishing to implement solutions to CM problems have a wide variety of operations literature to draw on that can address scheduling and patient throughput, but there are also a number of studies that consider electronic and technological solutions to CM problems. All of these solutions have the potential to positively influence the quality of patient care, including satisfaction.
