BackgroundTriage for patients' prioritization in the emergency department is a suitable solution to decrease overcrowding. Different methods are used for prioritization that needs effectiveness evaluation.ObjectivesThe aim of this study was to assess the effectiveness of the emergency severity index (ESI) 5-level triage system in contrast with spot check triage.Patients And MethodsData for this quasi-experimental study were extracted using a form to review 770 records of patients referred to emergency department of Imam Khomeini hospital (in Sari, north of Iran) during two separated periods each for four months; the first from 20th March to 19th July 2010 and the other from 21 March to 20 July 2011. The method used in the first time was spot check triage and the second one ESI triage. Data were processed with descriptive statistics and analyzed using independent samples t-test (CI = 95%).ResultsIncrease from 6.46 to 8.92 minutes in the average time from patient arrival to being visited by a physician (P < 0.001) and increase in average time from physician visit to receive the first nursing care from 7.68 to 15.89 minutes were significant (P < 0.001). The average waiting time for laboratory services was significantly decreased from 112.3 to 84.1 (P = 0.033). Increase in the average waiting time for radiology, decrease in average waiting time for sonography, average length of stay in the emergency department, and number of patients per emergency bed were not significant.ConclusionsBetween the two systems of triage, ESI was more effective than the spot check and in the spatial and temporal domain of research, was a successful method in improving some indicators of emergency and improving the performance indices. Hospital managers by implementation of ESI system can take a step toward new health policies and improve the processes as key tools of continuous quality improvement system.
