Cases of Note

As health care systems across the United States continue to grapple with emergency department (ED) crowding and identify mechanisms to improve ED throughput, quantification of intradepartmental efficiency and workload is required to provide much-needed objective measures to assist in the continuing development, implementation, and evaluation of these strategic initiatives. In an attempt to establish a straightforward measure of ED efficiency in relation to daily census and ED crowding, T. J. Flottemesch (2006) developed the ED Census Model. The purpose of this study was to apply the ED Census Model in a Southwestern U.S. community hospital setting. This application of the ED Census Model yielded 3 components: the ED Census Component, the ED Throughput Component, and the ED Efficiency Threshold Component. The components provide information necessary for understanding the impact of patient arrivals and departures on the underlying workflow processes that determine throughput.
