■先前的研究报道了院外心脏骤停(OHCA)干预措施的种族差异,包括旁观者CPR和AED的使用。然而,其他院前干预措施的研究有限.这项研究的主要目的是调查院外心脏骤停(OHCA)干预措施中的种族/种族差异:EMS响应时间,药物管理,以及逮捕内运输的决定。次要目标是评估旁观者CPR(CPR)的提供和AED应用的差异。
■我们回顾性分析了盐湖城消防局(2010-2023年)的数据。我们纳入了18岁或以上接受EMS治疗的OHCA的成年人。种族/民族被归类为白人,亚洲人,黑人,西班牙裔人,和其他人。我们采用多变量回归分析来评估种族/民族与感兴趣的结果之间的关联。
■未经调整的分析显示,在EMS反应中,各民族之间没有显着差异,药物管理,旁观者心肺复苏术,或内部逮捕运输决定。然而,在自动体外除颤器(AED)使用方面观察到显著的种族差异,黑人的比率最低(6.5%),亚洲人的比率最高(21.8%)。调整后的分析发现,种族/民族与所有OHCA干预措施之间没有显着关联,在种族/民族和生存结果之间也是如此。
■我们的多变量分析发现,种族/民族与EMS响应时间之间没有统计学上的显着关联,肾上腺素给药,抗心律失常药物的使用,旁观者心肺复苏术,AED干预,或逮捕内运输。这些结果暗示OHCA种族差异的区域差异可能在所有地区都不一致,有必要进一步研究其他地区的差距和其他影响因素,如邻里条件和社会经济地位。
UNASSIGNED: Previous research has reported racial disparities in out-of-hospital cardiac arrest (OHCA) interventions, including bystander CPR and AED use. However, studies on other prehospital interventions are limited. The primary objective of this study was to investigate race/ethnic disparities in out-of-hospital cardiac arrest (OHCA) interventions: EMS response times, medication administration, and decisions for intra-arrest transport. The secondary objective was to evaluate differences in the provision of Bystander CPR (CPR) and application of AED.
UNASSIGNED: We retrospectively analyzed data from the Salt Lake City Fire Department (2010-2023). We included adults 18 years or older with EMS-treated OHCA. Race/ethnicity was categorized as White people, Asian people, Black people, Hispanic people, and others. We employed multivariable regression analysis to evaluate the association between race/ethnicity and the outcomes of interest.
UNASSIGNED: Unadjusted analyses revealed no significant differences across ethnic groups in EMS response, medication administration, bystander CPR, or intra-arrest transport decisions. However, significant ethnic disparities were observed in Automated External Defibrillator (AED) utilization, Black people having the lowest rate (6.5%) and Asian people the highest (21.8%). The adjusted analysis found no significant association between race/ethnicity and all OHCA intervention measures, nor between race/ethnicity and survival outcomes.
UNASSIGNED: Our multivariable analysis found no statistically significant association between race/ethnicity and EMS response time, epinephrine administration, antiarrhythmic medication use, bystander CPR, AED intervention, or intra-arrest transport. These results imply regional variations in ethnic disparities in OHCA may not be consistent across all areas, warranting further research into disparities in other regions and additional influential factors like neighborhood conditions and socioeconomic status.
