BACKGROUND Bystander cardiopulmonary resuscitation (B-CPR) delivery and survival after out-of-hospital cardiac arrest vary at the neighborhood level, with lower survival seen in predominantly black neighborhoods. Although the Hispanic population is the fastest-growing minority population in the United States, few studies have assessed whether the proportion of Hispanic residents in a neighborhood is associated with B-CPR delivery and survival from out-of-hospital cardiac arrest. We assessed whether B-CPR rates and survival vary by neighborhood-level ethnicity. We hypothesized that neighborhoods with a higher proportion of Hispanic residents have lower B-CPR rates and lower survival. METHODS We conducted a retrospective cohort study using data from the Resuscitation Outcomes Consortium Epistry at US sites. Neighborhoods were classified by census tract based on percentage of Hispanic residents: <25%, 25% to 50%, 51% to 75%, or >75%. We independently modeled the likelihood of receipt of B-CPR and survival by neighborhood-level ethnicity controlling for site and patient-level confounding characteristics. RESULTS From 2011 to 2015, the Resuscitation Outcomes Consortium collected 27 481 US arrest events; after excluding pediatric arrests, emergency medical services-witnessed arrests, or arrests occurring in a healthcare or institutional facility, 18 927 were included. B-CPR was administered in 37% of events. In neighborhoods with <25% Hispanic residents, B-CPR was administered in 39% of events, whereas it was administered in 27% of events in neighborhoods with >75% Hispanic residents. Compared with <25% Hispanic neighborhoods in a multivariable analysis, out-of-hospital cardiac arrest in predominantly Hispanic neighborhoods had lower B-CPR rates (51% to 75% Hispanic: odds ratio, 0.79 [CI, 0.65-0.95], P=0.014; >75% Hispanic: odds ratio, 0.72 [CI, 0.55-0.96], P=0.025) and lower survival rates (global P value 0.029; >75% Hispanic: odds ratio, 0.56 [CI, 0.34-0.93], P=0.023). CONCLUSIONS Individuals with out-of-hospital cardiac arrest in predominantly Hispanic neighborhoods were less likely to receive B-CPR and had lower likelihood of survival. These findings suggest a need to understand the underlying disparities in cardiopulmonary resuscitationdelivery and an unmet cardiopulmonary resuscitationtraining need in Hispanic communities.

基于社区水平种族特征的旁观者心肺复苏实施和院外心脏骤停后存活率的变化。

背景 院外心脏骤停后旁观者心肺复苏 (B-CPR) 的实施和存活率在社区水平上有所不同,在以黑人为主的社区中存活率较低。尽管西班牙裔人口是美国增长最快的少数民族人口,但很少有研究评估社区中西班牙裔居民的比例是否与 B-CPR 实施和院外心脏骤停的存活率相关。我们评估了 B-CPR 率和生存率是否因邻里种族而异。我们假设西班牙裔居民比例较高的社区具有较低的 B-CPR 率和较低的存活率。方法 我们使用来自美国站点的 Resuscitation Outcomes Consortium Epistry 的数据进行了一项回顾性队列研究。社区根据西班牙裔居民的百分比按人口普查区分类:<25%、25% 至 50%、51% 至 75% 或 >75%。我们独立地模拟了接受 B-CPR 和生存的可能性,方法是控制现场和患者水平的混杂特征的社区水平种族。结果 从 2011 年到 2015 年,Resuscitation Outcomes Consortium 收集了 27 481 起美国逮捕事件;在排除儿科逮捕、紧急医疗服务目击逮捕或发生在医疗保健或机构设施中的逮捕后,共包括 18 927 人。在 37% 的事件中实施了 B-CPR。在西班牙裔居民少于 25% 的社区中,B-CPR 在 39% 的事件中进行,而在西班牙裔居民超过 75% 的社区中,B-CPR 在 27% 的事件中进行。与 < 在多变量分析中,25% 的西班牙裔社区,主要是西班牙裔社区的院外心脏骤停具有较低的 B-CPR 率(51% 至 75% 西班牙裔:比值比,0.79 [CI,0.65-0.95],P=0.014; >75% 西班牙裔:优势比,0.72 [CI,0.55-0.96],P=0.025)和较低的存活率(全球 P 值 0.029;>75% 西班牙裔:优势比,0.56 [CI,0.34-0.93],P= 0.023)。结论 在以西班牙裔为主的社区发生院外心脏骤停的个体接受 B-CPR 的可能性较小,并且存活的可能性较低。这些发现表明需要了解心肺复苏实施的潜在差异以及西班牙裔社区未满足的心肺复苏培训需求。在以西班牙裔为主的社区中,院外心脏骤停的 B-CPR 率较低(51% 至 75% 西班牙裔:优势比,0.79 [CI,0.65-0.95],P=0.014;>75% 西班牙裔:优势比,0.72 [CI, 0.55-0.96], P=0.025) 和较低的存活率(全球 P 值 0.029;>75% 西班牙裔:优势比,0.56 [CI, 0.34-0.93], P=0.023)。结论 在以西班牙裔为主的社区发生院外心脏骤停的个体接受 B-CPR 的可能性较小,并且存活的可能性较低。这些发现表明需要了解心肺复苏实施的潜在差异以及西班牙裔社区未满足的心肺复苏培训需求。在以西班牙裔为主的社区中,院外心脏骤停的 B-CPR 率较低(51% 至 75% 西班牙裔:优势比,0.79 [CI,0.65-0.95],P=0.014;>75% 西班牙裔:优势比,0.72 [CI, 0.55-0.96], P=0.025) 和较低的存活率(全球 P 值 0.029;>75% 西班牙裔:优势比,0.56 [CI, 0.34-0.93], P=0.023)。结论 在以西班牙裔为主的社区发生院外心脏骤停的个体接受 B-CPR 的可能性较小,并且存活的可能性较低。这些发现表明需要了解心肺复苏实施的潜在差异以及西班牙裔社区未满足的心肺复苏培训需求。025) 和较低的存活率(全球 P 值 0.029;>75% 西班牙裔:优势比,0.56 [CI,0.34-0.93],P=0.023)。结论 在以西班牙裔为主的社区发生院外心脏骤停的个体接受 B-CPR 的可能性较小,并且存活的可能性较低。这些发现表明需要了解心肺复苏实施的潜在差异以及西班牙裔社区未满足的心肺复苏培训需求。025) 和较低的存活率(全球 P 值 0.029;>75% 西班牙裔:优势比,0.56 [CI,0.34-0.93],P=0.023)。结论 在以西班牙裔为主的社区发生院外心脏骤停的个体接受 B-CPR 的可能性较小,并且存活的可能性较低。这些发现表明需要了解心肺复苏实施的潜在差异以及西班牙裔社区未满足的心肺复苏培训需求。
