Introduction
Glasgow Coma Scale score (GCS) obtained in the hospital has been shown to predict mortality well [1]. However, the performance of GCS in the prehospital setting has not been previously studied. We hypothesized that GCS would be an adequate method for triage and for outcome prediction also when obtained prehospitally. It is crucial to identify lifethreatening emergencies in the very early phase in order to shorten the time for initial assessment and further in-hospital visitation, as the time spent in the Emergency Department (ED) is related to mortality [2].
