摘要

背景急诊医疗服务(EMS)将患者送往急诊科(ED)时,通常会提前打电话提供预计到达时间(ETA)。准确的 ETA 有利于急诊科在病人到达前做好准备和资源分配。研究旨在确定急诊医疗服务(EMS)地面单位提供的预计到达时间(ETA)的准确性。主要结果是 EMS 报告的 ETA 与实际到达时间(ATA)之间的时间差。ATA 和 ETA 之间的差异采用双侧 Wilcoxon Signed-Rank 检验进行比较。我们还进行了分组分析,以评估特定类型转运的 ETA 准确性,并评估不同月份和时间的差异性。ATA-ETA 差值的总体中位数为 3 分钟(IQR 1-5 分钟),范围为 -26-48 分钟(Z=-25.139,p<0.001)。急救中心低估了961例(81.7%)的ETA,94例(8.0%)的ETA精确度在1分钟以内。ATA和ETA之间的最大差异出现在07:00-07:59和16:00-16:59之间(5分钟,IQR 2-7)。结论我们的数据表明,在大多数地面转运中,院前医疗服务提供者低估了到达急诊室的时间;但是,估计到达时间和实际到达时间的中位数差异很小。

Accuracy of Prehospital Services' Estimated Time to Arrival for Ground Transport to the Emergency Department

Background

Emergency medical services (EMS) transporting patients to the emergency department (ED) typically call ahead to provide an estimated time to arrival (ETA). Accurate ETA facilitates ED preparation and resource allotment in anticipation of patient arrival.

Objective

The study purposed to determine the accuracy of ETA provided by EMS ground units.

Methods

We performed a single-center, prospective, observational study of ED patients arriving via EMS ground transport. The primary outcome was the time difference between EMS-reported ETA and actual time of arrival (ATA). The difference between ATA and ETA was compared using the two-sided Wilcoxon Signed-Rank Test. Subgroup analysis was performed to evaluate ETA accuracy for specific types of transports and assess variability by month and time of day.

Results

We included 1176 patient transports in the final analysis. The overall median difference ATA-ETA was 3 min (interquartile range 1–5 min) with a range of −26–48 minutes (Z = −25.139, p < 0.001). EMS underestimated ETA in 961 cases (81.7%), and 94 ETAs (8.0%) were accurate to within 1 min. The largest difference between ATA and ETA occurred between 07:00–07:59 and 16:00–16:59 (5 min, interquartile range 2–7).

Conclusion

Our data demonstrate that prehospital providers underestimate time to ED arrival in most ground transports; however, the median difference between estimated and actual time to arrival is small.
