摘要

Emergency department (ED) length of stay (LOS) is associated with ED crowding and related complications. Previous studies either analyzed single patient disposition groups or combined different endpoints as a whole. The aim of this study is to evaluate different effects of relevant factors affecting ED LOS among different patient disposition groups. This is a retrospective electronic data analysis. The ED LOS and relevant covariates of all patients between January 2013 and December 2013 were collected. A competing risk accelerated failure time model was used to compute endpoint type-specific time ratios (TRs) for ED LOS. A total of 149,472 patients was included for analysis with an overall medium ED LOS of 2.15 [interquartile range (IQR)=6.51] hours. The medium LOS for discharged, admission, and mortality patients was 1.46 (IQR=2.07), 11.3 (IQR=33.2), and 7.53 (IQR=28.0) hours, respectively. In multivariate analysis, age (TR=1.012, P
