Multicenter Study Clinical Trial
Refining Emergency Severity Index triage criteria.
The Emergency Severity Index (ESI) version 3 is a five-level triage acuity scale with demonstrated reliability and validity. Patients are rated from ESI level 1 (highest acuity) to ESI level 5 (lowest acuity). Clinical experience has demonstrated two levels of ESI level 2 patients: those who require immediate intervention and those who are stable to wait for at least ten minutes. Studies have found that few patients are rated ESI level 1, and it has been suggested that revisions to the ESI might result in appropriate reclassification of some sickest level 2 patients as level 1. The purpose of this study was to identify level 2 patients who might be reclassified as level 1 patients. ⋯ Specific clinical findings at triage for a subset of ESI level 2 patients were associated with immediate delivery of lifesaving interventions. Revisions to the ESI level 1 criteria may be beneficial.
