Emergency Department Performance Indexes Before and After Establishment of Emergency Medicine

Emergency department performance index (EPI) greatly influences the function of other hospital’s units and also patient satisfaction. Recently، the Iranian Ministry of Health has defined specific national EPI containing five indexes. In the present study، the performance indexes of emergency department (ED) in one educational hospital has been assessed before and after establishment of emergency medicine. In the present cross-sectional study the ED of Shohadaye Tajrish Hospital، Tehran، Iran has been assessed during one-year period from March 2012 to February 2013. The study was divided into two six-month periods، before and after establishment of emergency medicine. Five performance indexes including: the percentage of patients were disposed during 6-hour، leaved the ED in a 12-hour، had unsuccessful cardiopulmonary resuscitations (CPR)، discharged against medical advice، and the mean time of triage were calculated using data of department of medical records on daily patients’ files. Then، Mann-Whitney U test was used to make comparisons at P<0. 05. The average triage time decreased from 6. 04 minutes in the first six months to 1. 5 minutes in the second six months (P=0. 06). The percentage of patients leaving the ED in a 12-hour decreased from 97. 3% to 90. 4% (P=0. 004). However، the percentage of disposed patients during 6-hour (P=0. 2)، unsuccessful CPR (P=0. 34) and discharged against medical advice (P=0. 42) did not differ between the two periods. It seems that establishment of emergency medicine could be able to improve ED performance indexes such as time to triage and leave in a 12-hour period.
