After cardiac arrest, the possibility of death or irreversible complications will highly increase in the absence of cardiac resuscitation within 4 to 6 minutes. Accordingly, measuring the pre-hospital services time intervals is important for better management of emergency medical services delivery. The purpose of this study then was to investigate pre-hospital time intervals for patients with heart attack in Arak city, based on locations and time variables.
This is a retrospective descriptive cross-sectional study, which was conducted at the Arak Emergency Medical Services (EMS) during 2017-2018. Data were analyzed by SPSS version 13.
The total number of heart attack patients registered in Arak emergency medical services was 2,659 of which 51% of patients were males. Six percent of patients were under 25 and about 49 percent were between 46 and 65 years old. The average of activation, response, on-scene, transportation, recovery and total time intervals were 3:30, 7:56, 15:15, 13:34, 11:07, 12:11, and 41:25, respectively. In the city area, the shortest and longest average response time intervals were in spring and winter, respectively. In out of the city area, the shortest average response time interval was in summer and the longest one in autumn. The shortest and the longest average response time intervals in the city area were in June and March, respectively, and in out of the city area, the shortest average response time interval was in June and the longest one in April.
The shorter response and delivery time interval compared to the other studies may indicate improvement in the provision of EMS. Special attention should be paid to the facilities and equipment of vehicles during cold seasons to be in the shortest possible time. Also, training and informing the staff more about the code of cardiac patients along with general public education can help improve these intervals.
心脏骤停后，如果在 4 到 6 分钟内没有进行心脏复苏，死亡或不可逆转并发症的可能性将大大增加。因此，测量院前服务时间间隔对于更好地管理紧急医疗服务的提供非常重要。本研究的目的是根据位置和时间变量，调查阿拉克市心脏病患者的院前时间间隔。
这是一项回顾性描述性横断面研究，于 2017 年至 2018 年在阿拉克紧急医疗服务处进行。数据采用 SPSS 版本 13 进行分析。
阿拉克紧急医疗服务中心共登记了 2659 例心脏病患者，其中 51%的患者为男性。6%的患者年龄在 25 岁以下，约 49%的患者年龄在 46 至 65 岁之间。激活、响应、现场、运输、恢复和总时间间隔的平均值分别为 3:30、7:56、15:15、13:34、11:07 和 12:11，分别为 41:25。在城市地区，最短和最长的平均响应时间间隔分别出现在春季和冬季。在城市地区外，最短的平均响应时间间隔出现在夏季，最长的出现在秋季。城市地区最短和最长的平均响应时间间隔分别出现在 6 月和 3 月，城市地区外最短的平均响应时间间隔出现在 6 月，最长的出现在 4 月。
与其他研究相比，响应和交付时间间隔较短表明紧急医疗服务的提供有所改善。在寒冷季节，应特别注意车辆的设施和设备，以尽可能缩短时间。此外，通过对员工进行有关心脏病人的培训和教育，并对公众进行一般教育，可以帮助改善这些时间间隔。
