The American College of Emergency Physicians (ACEP) believes that the quality of patient care benefits from implementing a standardized emergency department (ED) triage scale and acuity categorization process. Based on expert consensus of currently available evidence, ACEP and ENA support the adoption of a scientifically validated triage scale such as the Emergency Severity Index (ESI). These organizations also support continued research and investigation to further refine patient acuity assignment, especially for high-risk populations.
