Abstract

Triage is sorting patients based on acuity in order to manage care in the emergency department (ED) {Mirhaghi, 2017 #60}(1). Medical institutes are trying to develop triage scales compatible with their own culture of care. A triage scale must be precise and comprehensive enough to guide triage nurses and eliminate uncertainty.
