Abstract

Background: Prehospital electrocardiogram (PHECG) shortens door-to-balloon time in patients with ST-elevation myocardial infarction. However, it may increase the prehospital service time, thus offsetting the benefits gained. The performance of PHECG could be influenced by the proficiency of the emergency medical technicians (EMTs).

Objectives: To investigate whether there are differences in the performance of PHECG between EMT-II and EMT-paramedics (EMT-P).

Methods: This prospectively designed, retrospectively analyzed study of PHECG was conducted in Taipei from February 2019 to April 2021. Comparisons were made between EMT-II and EMT-P teams. The primary outcomes were the acceptance of PHECG suggestions and prehospital service time. The secondary outcomes were gender disparities in the primary outcomes.

Results: A total of 2,991 patients were included, of whom 2,617 received PHECG. For the primary outcomes, the acceptance of PHECG was higher in those approached by EMT-P (99.6% vs. 71.5%, p < 0.001). The scene time and scene-to-hospital time showed no significant differences. For gender disparities, the acceptance of PHECG in female patients was significantly lower in those approached by EMT-II (59.3% vs. 99.2%, p < 0.001). The scene time and scene-to-hospital time were generally longer in the female patients, especially in the younger and middle age groups. Compared to EMT-P, both were significantly longer in the female patients approached by EMT-II.

Conclusions: The acceptance of PHECG was lower in those approached by EMT-II, especially in females. Although there were generally no significant differences between EMT-II and EMT-P, the scene time and scene-to-hospital time were significantly longer in female patients, especially in those aged < 75 years approached by EMT-II.

院前心电图的性能及对院前服务时间的影响：EMT-II 和 EMT-P 团队之间的比较。

背景：院前心电图（PHECG）可缩短ST段抬高型心肌梗死患者从门诊到气囊的时间。然而，它可能会增加院前服务时间，从而抵消所获得的益处。PHECG的性能可能会受到急救医疗技术人员（EMTs）熟练程度的影响：调查二级急救医疗技术人员（EMT-II）和急救医疗技术人员辅助人员（EMT-P）的 PHECG 性能是否存在差异：这项前瞻性设计、回顾性分析的 PHECG 研究于 2019 年 2 月至 2021 年 4 月在台北进行。对 EMT-II 和 EMT-P 团队进行了比较。主要结果是对 PHECG 建议的接受程度和院前服务时间。次要结果是主要结果中的性别差异：结果：共纳入 2,991 名患者，其中 2,617 人接受了 PHECG。就主要结果而言，由急救医生接诊的患者接受 PHECG 的比例更高（99.6% 对 71.5%，P < 0.001）。现场时间和现场到医院的时间没有明显差异。在性别差异方面，女性患者接受 PHECG 的比例在由 EMT-II 接诊的患者中明显较低（59.3% 对 99.2%，P < 0.001）。女性患者的现场时间和现场到医院的时间普遍较长，尤其是中青年患者。与 EMT-P 相比，由 EMT-II 接诊的女性患者的现场时间和从现场到医院的时间都明显更长：结论：通过 EMT-II 接诊的患者对 PHECG 的接受度较低，尤其是女性。尽管 EMT-II 和 EMT-P 之间总体上没有明显差异，但女性患者的现场时间和现场到医院的时间明显更长，尤其是 EMT-II 接诊的年龄小于 75 岁的患者。
