Accuracy of the Emergency Department Triage System using the Emergency Severity Index for Predicting Patient Outcome; A Single Center Experience
Message:
Abstract:
Objective
To evaluate the accuracy of the five-level triage system using the emergency severity index (ESI) and to determine the compliance of the triage level with patient outcomes.
Methods
This was a cross-sectional study which was performed in the emergency department of Imam Reza Hospital of Mashhad during 2017. We included all the adult patients (≥15 years of age) referring to the emergency department. The data were recorded in a questionnaire containing three sections including demographic information, results of triage by ESI and final outcome of the patient. Patients referred to the triage unit were simultaneously triaged by triage nurse and some emergency medicine physicians. The triage was performed by a nurse with an emergency medicine physician (EMP) was considered as a gold standard and the outcome was compared in 24 hours later.
Results
Overall, we included 400 patients with a mean age of 46.40 ± 18.52 years among whom there were 211 (52.8%) men and 189 (47.3%) women. Finally, 123 patients were hospitalized, 12 died, 256 were discharged by a physician, and 9 people left the hospital with their own consent. The calculated weight kappa was used to determine the agreement between the observers (nurse triage and physician) at 0.701 so that the agreement between the triage performed by a nurse and an EMP was in an excellent level (p<0.001). There was a significant relationship between the triage levels (determined by physicians) and the outcome of the patient (p<0.001), and the five-level system had a high overlap and significant relation with patient's outcome.
Conclusion
The results of the current study revealed that the five-level triage system using the ESI has a high accuracy in triage and estimates the patient outcomes effectively and thus, could be used as an effective system in hospital triage.
