Prehospital triage and communication performance in small mass casualty incidents: a gauge for disaster preparedness.
Because of their infrequency, disasters are difficult to train for. Emergency prehospital personnel frequently participate in small mass casualty incidents (MCIs) (3 to 50 victims). This study sought to examine prehospital performance in small MCIs in areas that are frequently mismanaged in disasters. Prospective data from the resource physician and retrospective data from tape recorded prehospital conversations were collected for a 9-month period. Clinical patient data, patient demographics, emergency medical services squad characteristics, and triage information were recorded. Forty-five consecutive MCIs were studied. Most of these were motor vehicle accidents. Prehospital providers included paid providers, nonpaid providers, and air and ground transport. The mean number of victims first identified (4.6%) was greatly different than the mean number of victims eventually transported from a scene (7.1%). Most patients were treated at a level 1 trauma center. Frequent errors included having multiple communicators on site (38%), misidentifying the number of victims (56%), and having unclear information for the resource physician (43%). Only 38% of events had prehospital triage information that was deemed appropriate in total. These results show that scene and triage errors are frequent in MCIs of small scale. This information can be used to assay a system's readiness for disasters.
