Emergency Severity Index (ESI) 5-level triage requires its own resources and tends to batch patients in an undifferentiated middle category. Automated triage systems represent a new approach.
What question this study addressed
How would an electronic triage system that generated triage categories through a machine learning algorithm compare with ESI 5-level triage?
What this study adds to our knowledge
The computer-supported approach better predicted need for hospitalization and critical care.
How this is relevant to clinical practice
Refinement of triage can better assist in emergency department flow and patient safety. The process developed here allowed greater differentiation of heterogenous ESI level 3 patients.
