Although bystander cardiopulmonary resuscitation (BCPR) plays an essential role in out-of-hospital cardiac arrest (OHCA) care, little is known about the bystander-patient relationship in the actual setting. This study aimed to assess the disparities in BCPR performed by a family member and that performed by a non-family member.
This population-based observational study involved all adult patients with witnessed OHCAs of medical origin in Niigata City, Japan, between January 2012 and December 2016, according to the Utstein style. We used logistic regression analysis to assess the association between the witnessing person and the probability of providing BCPR. Next, among those who received BCPR, we sought to investigate the difference between BCPR performed by family and that performed by non-family members in terms of whether those who witnessed the arrests actually performed BCPR.
During the study period, 818 were eligible for this analysis, with 609 (74.4%) patients witnessed by family and 209 (25.6%) patients witnessed by non-family members. Multivariable logistic regression analysis showed that OHCA patients witnessed by family were less likely to receive BCPR compared to those witnessed by non-family members (260/609 [42.7%] versus 119/209 [56.9%], P = 0.017). Among the witnessed patients for whom BCPR was performed, the proportion of BCPR actually performed by a family member was lower than that performed by a non-family member (242/260 [93.1%] versus 116/119 [97.5%], P = 0.011).
In this community-based observational study, we found that a witnessing family member is less likely to perform BCPR than a witnessing non-family member.
尽管旁观者心肺复苏（BCPR）在院外心脏骤停（OHCA）的救治中起着至关重要的作用，但在实际情况下，旁观者与患者之间的关系鲜为人知。本研究旨在评估家庭成员和非家庭成员实施 BCPR 的差异。
本研究为基于人群的观察性研究，纳入了 2012 年 1 月至 2016 年 12 月在日本新潟市发生的有目击者的、起源于医学的成人 OHCA 患者，符合 Utstein 风格。我们使用逻辑回归分析评估目击者与提供 BCPR 概率之间的关联。接下来，在接受 BCPR 的患者中，我们试图调查在实际实施 BCPR 的人中，旁观者为家庭成员和非家庭成员时 BCPR 实施的差异。
在研究期间，818 例患者符合本分析条件，其中 609 例（74.4%）由家庭成员目击，209 例（25.6%）由非家庭成员目击。多变量逻辑回归分析显示，与非家庭成员目击的 OHCA 患者相比，家庭成员目击的患者接受 BCPR 的可能性较低（260/609 [42.7%] 与 119/209 [56.9%]，P = 0.017）。在实施 BCPR 的目击患者中，实际由家庭成员实施 BCPR 的比例低于非家庭成员（242/260 [93.1%] 与 116/119 [97.5%]，P = 0.011）。
在这项基于社区的观察性研究中，我们发现目击的家庭成员实施 BCPR 的可能性低于目击的非家庭成员。
