To determine the accident rate for Australian helicopter emergency medical services (HEMS) per 100,000 flying hours and to determine the patient mortality risk per mission from a HEMS accident.
Retrospective observational study of Australian HEMS flying hours and accidents from 1992-2002.
The calculated accident rate for Australian HEMS is 4.38 per 100,000 flying hours. One patient died as a direct result of helicopter accident in 50,164 missions. Overall, one accident occurred every 16,721 missions.
The overall Australian HEMS accident rate is similar to that reported from other countries, with all accidents occurring in Queensland community HEMS. Helicopters flown at night under Visual Flight Rules (VFR) appear to represent a high-risk subgroup. HEMS flights do not appear to present significant mortality risk to patients being transported.
确定澳大利亚直升机紧急医疗服务（HEMS）每10万飞行小时的事故率，并确定直升机紧急医疗服务事故中每次任务的患者死亡风险。
对1992年至2002年澳大利亚直升机紧急医疗服务的飞行小时数和事故进行回顾性观察研究。
计算得出澳大利亚直升机紧急医疗服务的事故率为每10万飞行小时4.38起。在50164次任务中，有1名患者因直升机事故直接死亡。总体而言，每16721次任务发生1起事故。
澳大利亚直升机紧急医疗服务的总体事故率与其他国家报告的事故率相似，所有事故均发生在昆士兰社区直升机紧急医疗服务中。夜间按照目视飞行规则（VFR）飞行的直升机似乎是一个高风险亚组。直升机紧急医疗服务飞行似乎不会给所运送的患者带来重大死亡风险。
