To evaluate the clinical performance and agreement of the AI-based Swiss Medical Assessment System (SMASS) compared to the standard Manchester Triage System (MTS) in non-trauma emergency department presentations.
Retrospective analysis of adult patients presenting with non-traumatic complaints to Kepler University Hospital in Linz, Austria, between November and December 2024 (N=1,021).
Each patient underwent standard nurse-led MTS triage in parallel with SMASS scoring, with SMASS blinded to clinical care decisions.
Inter-system concordance was poor, demonstrating low overall agreement with a Cohen's kappa of 0.167.
SMASS categorized 19% of high-acuity MTS 'orange' patients as non-urgent and 28% of low-acuity MTS 'green' patients as urgent.
Hospitalization was ultimately required for 23% of the patients who were designated as non-urgent by SMASS.

Implication

Retrospective study shows low agreement between AI-driven triage and the Manchester Triage System in emergency patients, indicating significant risks of misclassification.
