Abstract

The purpose of this study was to compare accident rates of helicopter emergency medical services (USA-HEMS) to domestic air taxi service (USA-Taxi) and helicopter emergency medical services in the Federal Republic of Germany (FRG-HEMS). Contingency tables compared the total hours flown to the number of fatal and non-fatal accidents for USA-HEMS (1982-7) vs. USA-Taxi (1980-5) and USA-HEMS (1982-7) vs. FRG-HEMS (1982-7). The overall accident rate for USA-HEMS was 11.7/100,000 h, with the fatal accident rate being 4.7/100,000 h. This was significantly different from the USA-Taxi overall accident rate of 6.7/100,000 h and the fatal accident rate of 1.6/100,000 h (chi 2 = 20.441, p = 0.0001). The USA-HEMS overall and fatal accident rates were not significantly different than the FRG-HEMS overall (10.9/100,000 h) and fatal (4.1/100,000 h) accident rate (chi 2 = 0.061, p = 0.97). These data suggest that emergency air transport is inherently more risky than routine air taxi services.

摘要

本研究的目的是比较美国直升机紧急医疗服务（USA - HEMS）与美国国内空中出租车服务（USA - Taxi）以及德意志联邦共和国直升机紧急医疗服务（FRG - HEMS）的事故率。列联表比较了USA - HEMS（1982 - 1987年）与USA - Taxi（1980 - 1985年）以及USA - HEMS（1982 - 1987年）与FRG - HEMS（1982 - 1987年）飞行总小时数与致命和非致命事故数量。USA - HEMS的总体事故率为11.7/100,000小时，致命事故率为4.7/100,000小时。这与USA - Taxi的总体事故率6.7/100,000小时和致命事故率1.6/100,000小时有显著差异（卡方 = 20.441，p = 0.0001）。USA - HEMS的总体和致命事故率与FRG - HEMS的总体事故率（10.9/100,000小时）和致命事故率（4.1/100,000小时）无显著差异（卡方 = 0.061，p = 0.97）。这些数据表明，紧急空中运输本质上比常规空中出租车服务风险更大。
