Triage and ESI

Accuracy in triage must overcome factors such as bias, environmental conditions, interruptions, experience and time constraints to get 139 million patients (visits, 2017 CDC) to the right care at the right time. The Emergency Severity Index is a five-level, emergency department triage program relied upon by nurses to assess patient acuity based on their presentation in the ED and the expected level of care the patient will require. ESI is used by approximately 80 percent of U.S. hospitals.
