Do pre-hospital anaesthesiologists reliably predict mortality using the NACA severity score? A retrospective cohort study
Introduction: The National Advisory Committee on Aeronautics’ (NACA) severity score is widely used in pre-hospital emergency medicine to grade the severity of illness or trauma in patient groups but is scarcely validated. The aim of this study was to assess the score’s ability to predict mortality a...

Trauma patients with NACA score 1–6 had overall mortality rate of 1.9% (12/625) and non-trauma patients 7.4% (67/908). The NACA score’s ability to predict mortality was assessed by using ROC area under curve (AUC) and was 0.86 for all, 0.82 for non-trauma and 0.98 for trauma patients. The NACA score’s ability to predict a need for respiratory therapy within 24 h revealed an AUC of 0.90 for all patients combined. Conclusion: The NACA score had good discrimination for predicting mortality and need for respiratory therapy. It is thus useful as a tool to measure overall severity of the patient population in this kind of emergency medicine system.
