Background/purpose: The importance of accurate triage in Taiwan is becoming more apparent with the increasing number of emergency department (ED) patients, and resources for the National Health Insurance becoming constrained. This study compared the ability of the Taiwan triage system (TTS) and the standardized 5-level Emergency Severity Index (ESI) triage system to predict ED resource utilization.
Methods: Patients arriving at the ED were triaged by both TTS and by using a two-page checklist of ESI criteria during the 3-month study period.
