Early recognition of cardiac arrest and early initiation of bystander cardiopulmonary resuscitation can increase the survival of patients with out-of-hospital cardiac arrest (OHCA). We compared dispatcher-assisted cardiopulmonary resuscitation (DACPR) effectiveness before and after using different communication models in the dispatching center. We analyzed dispatch recordings of non-trauma origin OHCA cases received by the Taichung dispatch center between May 1 to September 30, 2021, and November 1, 2021, to March 31, 2022. The dispatchers underwent an 8-hour training intervention consisting of targeted education using a new communication model for DACPR. Several outcome measures were evaluated, including the sustained return of spontaneous circulation and the time to first chest compression. We included 640 cases in the preintervention group and 580 cases in the postintervention group. The return of spontaneous circulation (ROSC) rate, the time to first chest compression, and good neurological outcome were significantly improved in the postintervention group (20.9% vs. 31.0%, < 0.001;168 seconds vs. 151 seconds, = 0.004; 2.8% vs. 5.3%, = 0.024, respectively). In subgroup analyses, the intervention was related to a statistical improvement in ROSC rate among patients whose caller was a family member (18.7% vs. 31.4%, < 0.001). Among patients whose caller was female, both ROSC and good neurological outcome significantly improved after the intervention (19.8% vs. 36.6%, < 0.001; 2.7% vs. 7.5%, = 0.006, respectively). There was a statistical difference between the pre-intervention and post-intervention group with respect to ROSC rate among patients whose caller was family (the adjusted odds ratio:1.78, 95% CI: 0.59–1.25], < 0.001.) or female (the adjusted odds ratio:3.18,95% CI: 1.77–5.70], = 0.008.) in the multivariable regression model. The new communication model has enhanced the effectiveness of DACPR in terms of the ROSC rate, particularly when the caller was a family member or female, leading to improved rates of ROSC and favorable neurological outcomes.

接受过说服性沟通技巧培训的调度员提高了调度员辅助心肺复苏的有效性

早期识别心脏骤停并尽早开始旁观者心肺复苏可以提高院外心脏骤停 (OHCA) 患者的生存率。我们比较了调度中心使用不同通信模式前后的调度员辅助心肺复苏（DACPR）效果。我们分析了台中调度中心在2021年5月1日至9月30日以及2021年11月1日至2022年3月31日期间收到的非外伤起源的OHCA病例的调度记录。调度员接受了8小时的培训干预，包括有针对性的培训干预使用新的 DACPR 沟通模式进行教育。评估了多项结果指标，包括自主循环的持续恢复和首次胸外按压的时间。我们纳入了干预前组 640 例和干预后组 580 例。干预后组的自主循环恢复 (ROSC) 率、首次胸外按压时间和良好的神经功能结果均显着改善（20.9% vs. 31.0%，< 0.001；168 秒 vs. 151 秒，= 0.004；2.8） % 与 5.3% 分别 = 0.024）。在亚组分析中，干预措施与来电者为家庭成员的患者 ROSC 率的统计改善有关（18.7% vs. 31.4%，< 0.001）。在呼叫者为女性的患者中，干预后 ROSC 和良好的神经功能结果均显着改善（分别为 19.8% vs. 36.6%，< 0.001；2.7% vs. 7.5%，= 0.006）。干预前和干预后组的 ROSC 率在呼叫者为家人（调整后比值比：1.78，95% CI：0.59-1.25]，< 0.001）或女性（<0.001）的患者中存在统计学差异。多变量回归模型中调整后的优势比：3.18,95% CI: 1.77–5.70], = 0.008.)。新的通信模式提高了 DACPR 在 ROSC 率方面的有效性，特别是当呼叫者是家庭成员或女性时，从而提高了 ROSC 率和良好的神经系统结果。
