Objective: The goal of this study was to determine patient and injury characteristics that predict undertriage and overtriage. Design: This study was a retrospective analysis of admissions for acute injury. Materials and Methods: All admissions for acute injuries in a 2 1/2 -year period were included (N = 26,025). ICD-9 clinical modification codes were converted to Injury Severity Scores. Main Results: Seventy-nine percent of severely injured patients were admitted to level I trauma centers. Severely injured patients admitted to other hospitals (undertriage) were more likely elderly (odds ratio = 5.44) and less likely had multisystem injuries (odds ratio = 0.55). One-fourth of patients with minor injuries were admitted to level I trauma centers (overtriage). Overtriaged patients were more likely intoxicated, obese, or had an injury to the head or face. Conclusions: In a developed trauma system, severely injured elderly trauma patients (especially females) are at risk for undertriage. The characteristics of patients at risk for overtriage reflect the difficulties of prospective out-of-hospital triage.
