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.
ESI Training Materials
The ESI materials, including four recorded lectures, 26 practice case videos, and an implementation handbook, are essential resources for ensuring that your emergency department staff are well trained in using ESI. The materials were previously available on DVD, so users who already have the DVD set do not need to replace any files. Users who got the DVD set before the handbook was updated in 2012 may want to download the newer version.
