Telephone-assisted cardiopulmonary resuscitation (TA-CPR) is an effective community intervention to increase bystander CPR rates. This study evaluated the effect of TA-CPR on the provision of bystander CPR as a function of the patient's sex.
Adult (aged ≥ 18 years) patients who collapsed in a public location between January 2013 and December 2017 and received emergency medical service (EMS) treatment for out-of-hospital cardiac arrest (OHCA) of presumed cardiac aetiology were included in the study. The main exposures were TA-CPR and the patients' sex. The primary outcome was the implementation of bystander CPR by laypersons. Multivariable logistic regression analysis was conducted, stratified based on the provision of TA-CPR, to examine the effect on bystander CPR according to patient sex.
In the final analysis, 15,840 patients with OHCAs were included. Patients who received TA-CPR accounted for 32.6% (5167/15,840) of the sample. Overall, 84.4% (814/964) of the women and 86.9% (3653/4203) of the men received bystander CPR in the TA-CPR group (P < 0.001). In the non-TA-CPR group, 40.5% (912/2252) of women and 47.3% (3653/8421) of men received bystander CPR (P < 0.001). In the multivariable logistic regression analysis, there was no significant difference in the odds ratio (OR) of bystander CPR according to patient sex in the TA-CPR group (adjusted OR [AOR], 0.83; 95% confidence interval [CI], 0.68-1.01). Women were less likely to receive bystander CPR if the bystanders are not directed by TA-CPR (AOR: 0.79; 95% CI, 0.70-0.87).
TA-CPR attenuated the sex disparity in bystander CPR provided in public places.
电话辅助心肺复苏（TA-CPR）是提高旁观者 CPR 率的一种有效的社区干预措施。本研究评估了 TA-CPR 对旁观者 CPR 实施的影响，以及其与患者性别之间的关系。
本研究纳入了 2013 年 1 月至 2017 年 12 月期间在公共场所发生心搏骤停（OHCA）的成年（年龄≥18 岁）患者，这些患者接受了紧急医疗服务（EMS）治疗，OHCA 的病因被认为是心脏性的。主要暴露因素为 TA-CPR 和患者的性别。主要结局为非专业人员实施旁观者 CPR。采用多变量逻辑回归分析，根据是否提供 TA-CPR 进行分层，以检查根据患者性别对旁观者 CPR 的影响。
最终纳入 15840 例 OHCA 患者。接受 TA-CPR 的患者占样本的 32.6%（5167/15840）。总体而言，在 TA-CPR 组中，女性中有 84.4%（814/964），男性中有 86.9%（3653/4203）接受了旁观者 CPR（P<0.001）。在非 TA-CPR 组中，女性中有 40.5%（912/2252），男性中有 47.3%（3653/8421）接受了旁观者 CPR（P<0.001）。在多变量逻辑回归分析中，在 TA-CPR 组中，根据患者性别，旁观者 CPR 的优势比（OR）没有显著差异（调整 OR [AOR]，0.83；95%置信区间 [CI]，0.68-1.01）。如果旁观者没有接受 TA-CPR 的指导，女性接受旁观者 CPR 的可能性较小（AOR：0.79；95% CI，0.70-0.87）。
TA-CPR 减轻了公共场所旁观者 CPR 实施中的性别差异。
