Comparison of two prehospital predictive models for mortality and impaired consciousness after severe traumatic brain injury.

Background: The primary aim was to investigate the performance of a National Advisory Committee for Aeronautics based predictive model (NACA-BM) for mortality at 14 days and a reference model using motor GCS (GCS-RM). The secondary aim was to compare the models for impaired consciousness of survivors at 14 days (IC-14; GCS ≤ 13).

Methods: Patients ≥16 years having sustained TBI with an abbreviated injury scale score of head region (HAIS) of >3 were included.
