Comparison of three emergency department triage systems among Thai medical students: A randomized three-period crossover simulation study

Introduction

In Thailand, the Emergency Severity Index (ESI) and Ministry of Public Health Emergency Department triage system (MOPH) are commonly used, whereas the Thai Rapid Initial Assessment and Grading for Emergency (TRIAGE) system has been newly proposed. Comparative evidence is limited. We compared correct triage as the primary outcome, with under-triage, over-triage, and completion time as secondary outcomes.
