BackgroundDifferent criteria are employed to activate trauma teams. Because of a growing concern about overtriage, the objective of this study was to investigate the performance of our trauma team's activation protocol.MethodsInjured patients with trauma team activation (TTA), admission to an intensive care unit or surgical intermediate care unit with a trauma diagnosis, or trauma-related death in the emergency department were investigated retrospectively from 1 January 2004 to 31 December 2005. Different TTA criteria were analysed with respect to sensitivity, positive predictive value (PPV) and overtriage (1 - PPV).ResultsEight hundred and nine patients were included, 185 (23%) of whom had an Injury Severity Score (ISS) of more than 15. The performance of our protocol showed a sensitivity of 87%, PPV of 22% and overtriage of 78%. The mechanism of injury as a TTA criterion had a sensitivity of 14%, PPV of 7% and overtriage of 93%. Physiological/anatomical criteria and interfacility transfer showed higher PPV and less overtriage. Undertriage (no TTA despite ISS > 15) was identified in 23 patients (13%), 18 of whom were hospital transfers.ConclusionA TTA protocol based on physiological, anatomical and interfacility transfer criteria seems to yield a higher precision than, in particular, that based on mechanism of injury criteria. Because of substantial overtriage in our hospital, the TTA protocol needs to be re-evaluated.
