Helicopter transport plays a fundamental role in modern health systems, and, yet, it is not been the focus of scientific research, especially in Italy. Our objective was to analyze Padua helicopter emergency medical services (HEMS) station operations to discover whether this resource has been used correctly and advantageously.
The study was conducted considering 115 helicopter air ambulance operations minutes in 2018. Additionally, using geographic information systems and estimated ambulance data, a comparison was drawn between air and ground emergency medical services.
Interfacility transports involved mainly adults. There were 65 (56.52%) "acute transports," 49 (42.61%) "back transports," and 1 "hyperspecialized care transport" (0.87%). The average route distance was 44.23 km; the modal class was 25 to 30 km. The average mission time was 1 hour 26 minutes; the modal class was 1 hour to 1 hour 15 minutes. The Pearson correlation coefficient between flying/traveling time and the route length was 0.92 for helicopter and 0.94 for ambulance, and between mission time and route length, it was 0.05 for helicopter and 0.94 for ambulance.
Helicopters are not always the fastest mode of transporting patients, and journey time is variable. Because of the importance of rapid response in emergency situations, we propose not to use helicopters for transports less than 50 km in distance.
直升机运输在现代卫生系统中起着至关重要的作用，但它尚未成为科学研究的焦点，尤其是在意大利。我们的目的是分析帕多瓦直升机紧急医疗服务（HEMS）站的运作情况，以发现该资源是否得到了正确和有利的利用。
本研究考虑了 2018 年 115 次直升机空中救护行动的分钟数。此外，利用地理信息系统和估算的救护车数据，对空中和地面紧急医疗服务进行了比较。
院际转运主要涉及成年人。有 65 例（56.52%）为“急性转运”，49 例（42.61%）为“回程转运”，1 例为“超专科护理转运”（0.87%）。平均路线距离为 44.23 公里；模态类别为 25 至 30 公里。平均任务时间为 1 小时 26 分钟；模态类别为 1 小时至 1 小时 15 分钟。直升机飞行/行驶时间与路线长度之间的皮尔逊相关系数为 0.92，救护车为 0.94；任务时间与路线长度之间的皮尔逊相关系数为直升机 0.05，救护车为 0.94。
直升机并不总是运送患者最快的方式，而且飞行时间是可变的。由于在紧急情况下快速反应的重要性，我们建议不要使用直升机运送距离小于 50 公里的患者。
