Performance of Sieve versus SwissPre Prehospital Triage Algorithms in a Simulated Mass-Casualty Incident: A Randomized Open-Label Study

The simpler Sieve algorithm may slightly outperform the more complex SwissPre in accurately categorizing critically injured patients who would likely die within 60 minutes if left untreated. No significant difference was observed in triage speed. However, these exploratory findings should be interpreted cautiously, considering the mean difference was modest and the controlled simulated setting, limiting generalizability.
