Abstract
BACKGROUND: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.
