Automatic standby (AS) of helicopter emergency medical services (HEMS) may allow improved utilization appropriateness (UA) for scene trauma, although this has not been studied.
HEMS records were reviewed for 16 months, including date, county of origin, and UA. Data were analyzed descriptively with chi(2) where appropriate.
Of 274 flights, there was no significant change in UA where AS was in place versus where it was not (P =.36). One county had an increase in total flights with AS in use without a significant change in UA (P =.10).
In this region, use of an AS policy for scene trauma resulted in increased utilization of HEMS without a corresponding change in UA. Specifically, inappropriate utilization did not increase. This finding suggests that such a policy does not incur overutilization despite increasing total flights. Further study with larger numbers is necessary to draw definitive conclusions.
直升机紧急医疗服务（HEMS）的自动待命（AS）可能会提高现场创伤的利用适宜性（UA），尽管尚未对此进行研究。
回顾了16个月的HEMS记录，包括日期、出发县和UA。在适当情况下，用卡方检验对数据进行描述性分析。
在274次飞行中，AS启用时与未启用时的UA没有显著变化（P = 0.36）。一个县在使用AS时总飞行次数增加，但UA没有显著变化（P = 0.10）。
在该地区，对现场创伤采用AS政策导致HEMS的利用率提高，而UA没有相应变化。具体而言，不适当的利用并未增加。这一发现表明，尽管总飞行次数增加，但该政策不会导致过度利用。需要进行更多数量的进一步研究才能得出明确结论。
