Abstract

Objective

Timely reperfusion is crucial for improving outcomes in patients with ST-elevation myocardial infarction (STEMI). The impact of transport mode on time to treatment for patients with STEMI over short distances (<10 miles) is not well studied. This study aimed to compare the time from transport request to percutaneous coronary intervention (PCI) suite arrival between helicopter emergency medical services (HEMS) and ground emergency medical services (GEMS) for patients with STEMI.

Methods

We conducted a retrospective cohort study involving 22 patients with STEMI transported by either HEMS or GEMS from a single referring hospital to a single receiving hospital PCI suite, located 8 miles apart, from January 2020 to January 2023. Data on transport times were collected from hospital records and Google Maps estimates. We analyzed the time intervals using descriptive and inferential statistics, including mean comparisons and regression analyses.

Results

Air transport (HEMS) was significantly faster than ground transport (GEMS) by a mean of 32 minutes (95% confidence interval: 21.1-42.9 minutes). This difference was clinically significant in 50% of the cases. Sensitivity analyses using longer HEMS transport times confirmed the robustness of the findings. No significant changes in transport times were observed over the study period.

Conclusion

HEMS may offer time advantages compared with GEMS for short-distance transfers in STEMI cases, though the small sample size limits the robustness of these findings. Further research with larger samples and additional outcome measures is needed to confirm these results and assess the broader implications for emergency medical transport.

对单个转诊-接收医院对进行纵向评估，以评估从运送请求到到达心导管实验室的空气与地面时间：一项观察性队列研究

目的及时再灌注对改善st段抬高型心肌梗死（STEMI）患者预后至关重要。短途（10英里）运输方式对STEMI患者治疗时间的影响尚未得到很好的研究。本研究旨在比较STEMI患者的直升机紧急医疗服务（HEMS）和地面紧急医疗服务（GEMS）从运送请求到经皮冠状动脉介入治疗（PCI）套房到达的时间。方法：我们进行了一项回顾性队列研究，纳入了2020年1月至2023年1月期间22例STEMI患者，由HEMS或GEMS从一家转诊医院转移到相隔8英里的一家接收医院PCI组。关于运输时间的数据是从医院记录和谷歌地图估计数据中收集的。我们使用描述性和推断性统计分析时间间隔，包括平均值比较和回归分析。结果航空运输（HEMS）比地面运输（GEMS）平均快32 min（95%置信区间：21.1 ~ 42.9 min）。这种差异在50%的病例中具有临床意义。使用更长的HEMS传输时间的敏感性分析证实了研究结果的稳健性。在研究期间，没有观察到运输时间的显著变化。结论与GEMS相比，hems在STEMI病例的短距离转移中可能具有时间优势，尽管样本量小限制了这些发现的稳健性。需要使用更大样本和其他结果测量进行进一步研究，以确认这些结果并评估对紧急医疗运输的更广泛影响。

期刊介绍： Air Medical Journal is the official journal of the five leading air medical transport associations in the United States. AMJ is the premier provider of information for the medical transport industry, addressing the unique concerns of medical transport physicians, nurses, pilots, paramedics, emergency medical technicians, communication specialists, and program administrators. The journal contains practical how-to articles, debates on controversial industry issues, legislative updates, case studies, and peer-reviewed original research articles covering all aspects of the medical transport profession.
