The association between time to disposition plan in the emergency department and in-hospital mortality of general medical patients

摘要: Background:  A perceived risk of time-limited emergency department (ED) assessment patients is inadequate workup leading to inappropriate disposition. The aim this study was examine the association time disposition plan (TDP) on ED length stay (LOS) and correlate mortality. Methods:  retrospective review data collected from information systems at three hospitals conducted between June 2008 October 2009. Included were admitted a general medical unit. Patients excluded if intensive care, coronary cardiac monitored bed or required surgery in first 24 h had an expected LOS <48 h. Multivariate regression analysis used identify independent associations with mortality. Results:  total 10 107 patient episodes analysed, which 6768 (67.0%) ≥8 h. There significant effect modification by TDP mortality. In setting longer LOS, <4 h associated significantly higher mortality (OR 1.57, 95% CI: 1.28–1.92, P < 0.001), corrected for age, gender triage category. This not when <8 h 0.88, 0.60–1.27, P= 0.49). Conclusions:  prolonged completing management within 4 h presentation Further prospective studies are understand relationship rapid decision making safety.
