Emergency Severity Index (ESI): A Triage Tool for Emergency Department

DVDs and 2012 Edition of the Implementation Handbook

Version 4


The Emergency Severity Index (ESI) is a five-level emergency department (ED) triage algorithm that provides clinically relevant stratification of patients into five groups from 1 (most urgent) to 5 (least urgent) on the basis of acuity and resource needs. The Agency for Healthcare Research and Quality (AHRQ) funded initial work on the ESI.
