Delays in emergency medical service (EMS) directly affect life-threatening emergencies. Delays also indirectly affect the perception and satisfaction of patients and their relatives, which are important qualitative EMS indicators.
For this cross-sectional study, data was collected from May 1 to July 31, 2021, through questionnaires developed by the authors. The study sample consisted of relatives of EMS patients. The primary objective was the perceived EMS response time, which was compared to the actual EMS response time. The secondary objective was the relatives' perceptions and feelings regarding the waiting time.
During study period, the sample was 165 relatives of patients managed by EMS. The mean perceived EMS response time of 18.28 ± 8.10 min was significantly longer than the mean actual response time of 14.44 ± 4.86 min (p < 0.001). The positive correlation between the perceived and actual times was low but statistically significant (p < 0.001) with a correlation coefficient of 0.315 (95% CI 0.170-0.446). The overall satisfaction level was high (, standard deviation 0.63). The mean perceived EMS response time compares with the high-to-highest satisfaction levels of relatives was significantly lower than the mean perceived EMS response time compares with the lowest-to-middle satisfaction levels of relatives (17.83 ± 8.05 and 22.50 ± 7.47 min, respectively; p = 0.028).
The perceived EMS response time was longer than the actual response time, with a low correlation. However, the relatives' overall satisfaction level was high.
紧急医疗服务（EMS）的延迟直接影响危及生命的紧急情况。延迟还会间接影响患者及其亲属的感受和满意度，而这些是重要的EMS质量指标。
在这项横断面研究中，于2021年5月1日至7月31日通过作者编制的问卷收集数据。研究样本包括EMS患者的亲属。主要目标是感知到的EMS响应时间，并将其与实际EMS响应时间进行比较。次要目标是亲属对等待时间的看法和感受。
在研究期间，样本为165名由EMS管理的患者的亲属。感知到的EMS平均响应时间为18.28±8.10分钟，显著长于实际平均响应时间14.44±4.86分钟（p<0.001）。感知时间与实际时间之间的正相关性较低，但具有统计学意义（p<0.001），相关系数为0.315（95%CI 0.170 - 0.446）。总体满意度较高（标准差0.63）。与亲属高至最高满意度水平相比的感知EMS平均响应时间显著低于与亲属最低至中等满意度水平相比的感知EMS平均响应时间（分别为17.83±8.05和22.50±7.47分钟；p = 0.028）。
感知到的EMS响应时间长于实际响应时间，相关性较低。然而，亲属的总体满意度较高。
