Few published studies on civilian helicopter emergency medical services (HEMS) hoist programs exist. This study provides a demographic analysis of hoist rescue operations performed by the only FAA Part 135 hoist-approved civilian HEMS operator in the United States.
All persons hoisted between May 29, 2001, and May 28, 2011, were retrospectively analyzed.
Over a 10-year period, 212 of 214 victims were hoisted. The most common indications were fall injuries (38%) and being stranded (21%). Victim demographics showed an average age of 35 ± 17years, predominantly male (79%), often associated with trauma (66%), with a majority (68%) of all victims requiring subsequent transport to a hospital by ground ambulance (24%) or flown by Life Flight (44%). Hoists occurred most often in the afternoon (14:07 ± 3:47 hours), during the weekend (53%), in the months of May-September (71%), at an altitude of 7,488 ± 1487 feet, with the seat harness (39%) being the most common mode of victim extraction. Hoist insertion of search and rescue (SAR) personnel occurred infrequently (5%).
The results from this demographic study on hoist operations can provide important demographic information for HEMS contemplating backcountry hoist operations and programs that interface with SAR agencies.
关于民用直升机紧急医疗服务（HEMS）吊运项目的已发表研究很少。本研究对美国唯一一家获得联邦航空管理局（FAA）第135部吊运批准的民用HEMS运营商所进行的吊运救援行动进行了人口统计学分析。
对2001年5月29日至2011年5月28日期间所有被吊运的人员进行回顾性分析。
在10年期间，214名受害者中有212人被吊运。最常见的指征是坠落伤（38%）和被困（21%）。受害者人口统计学显示，平均年龄为35±17岁，以男性为主（79%），常伴有创伤（66%），所有受害者中的大多数（68%）随后需要通过地面救护车（24%）或空中医疗救援（44%）转运至医院。吊运最常发生在下午（14:07±3:47）、周末（53%）、5月至9月（71%）、海拔7488±1487英尺处，使用座椅安全带（39%）是最常见的受害者解救方式。吊运插入搜救（SAR）人员的情况很少见（5%）。
这项关于吊运操作的人口统计学研究结果可为考虑在偏远地区进行吊运操作的HEMS以及与SAR机构对接的项目提供重要的人口统计学信息。
