BACKGROUND
Helicopters provide rapid interfacility transport, but the effect on patients is largely unknown.
METHODS
Patients requested to be transported between facilities by helicopter were followed prospectively to determine survival, disability, health status, and health care utilization. A total of 1,234 patients were transported by the primary aeromedical company; 153 patients were transported by ground and 25 patients were transported by other aeromedical services because of weather or unavailability of aircraft.
RESULTS
There were no differences at 30 days for survivors in disability, health status, or health care utilization. Nineteen percent of helicopter-transported patients died compared with 15% of those transported by ground (p=0.21).
CONCLUSION
The patients transported by helicopter did not have improved outcomes compared with patients transported by ground. These data argue against a large advantage of helicopters for interfacility transport. A randomized trial is needed to address these issues conclusively.
背景
直升机可提供快速的机构间转运，但对患者的影响很大程度上未知。
方法
对请求通过直升机在机构间转运的患者进行前瞻性随访，以确定其生存率、残疾情况、健康状况和医疗保健利用情况。共有1234例患者由主要的航空医疗公司转运；153例患者通过地面转运，25例患者因天气或飞机不可用而由其他航空医疗服务转运。
结果
幸存者在30天时的残疾情况、健康状况或医疗保健利用方面没有差异。直升机转运患者的死亡率为19%，而地面转运患者的死亡率为15%（p = 0.21）。
结论
与地面转运的患者相比，直升机转运的患者结局并未改善。这些数据表明直升机在机构间转运方面没有很大优势。需要进行一项随机试验来最终解决这些问题。
