An objective analysis of an accident flying squad

An objective evaluation of an accident flying squad, in relation to trauma call-outs during a six month period, was performed using the Injury Severity Score and the recently described Revised TRISS methodology. We have demonstrated improvement in patient survival for those trauma cases treated at the scene. This has not been previously documented. Objective evaluation of these squads in relation to medical emergencies is even more difficult. The profile of these call-outs is described. (11.1%) of those treated at the scene for cardiac arrest survived to leave hospital. Ventricular fibrillation was the primary arrhythmia recorded in this group of survivors. This supports the vogue for extended ambulance personnel training.
