Cardiac arrest & resuscitation
Racial and ethnic differences in bystander cardiopulmonary resuscitation for opioid-associated out-of-hospital cardiac arrests
Authors' conclusion
Findings from this study identify specific demographic categories (e.g. age, race/ethnicity) that are significantly less likely to receive bCPR.

- Participants
- 19,612 EMS-assessed opioid overdoses
- Exposure
- Black, Hispanic, Asian, American Indian/Native Alaskan, Hawaiian/Pacific Islander vs White patients
- Outcome
- Bystander-administered CPR
Methodological detailsmultivariable logistic regression, US NEMSIS dataset 2017–2025

Bystander CPR by age (hierarchical analysis)
- Younger patients more likely to receive bystander cardiopulmonary resuscitation (bCPR) across racial/ethnic groups; older patients significantly less likely
