An Analytical Review of the Emergency Department at William Beaumont Army Medical Center in Response to Overcrowding and Army Growth and Realignment Initiatives
Abstract
Increased emergency department (ED) visits brought about by limited outpatient care capacity are resulting in ED overcrowding and volatile emergency systems across the country. William Beaumont Army Medical Center (WBAMC) ED is experiencing this ED overcrowding phenomenon and the unprecedented growth of 66,000 beneficiaries over eight years (Fiscal Year 2006 thru 2013). The blending of the two has led to new challenges and the need for optimization of current ED resources. The purpose of this paper is to determine what changes must take place in the WBAMC ED in order to maximize resource utilization. Several steps narrowing in scope were used to evaluate the WBAMC ED. Using ANOVA three periods were tested and found to be significant at the p less than .05 level for ED Visits and ED Average Length of Stay (LOS). Based on these results a queuing analysis was conducted to evaluate congestion and to create an ED LOS/Staffing Model. A statistically significant ED LOS multiple linear regression model with a R2 of 0.13 with F (5, 8259)=243.39, P less than .001 was then used to help determine several courses of action that would improve input/throughput/output.
