Emergency Severity Index


Implementation Handbook and DVD

The Emergency Severity Index (ESI) is a 5-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 2012 edition of the Implementation Handbook, which can be used alone or with the DVDs, discusses the ESI and the research behind it. The handbook also includes information on:

  • Pediatric triage--new with this edition.
  • Frequently asked questions.
  • Additional practice cases.
  • Full-page and pocket-sized versions of the ESI Version 4 Algorithm that emergency department personnel can cut out and refer to as needed.
