Cardiac arrest & resuscitation
Racial and ethnic disparities amongst patients with lay rescuer automated external defibrillator placement after out-of-hospital cardiac arrest
Authors' conclusion
When compared to White persons, the odds of lay rescuer AED use in OHCA was between 31-38% lower for American Indian/Alaskan Native, Asian, Hispanic, and Native Hawaiian/Pacific Islander persons, and 10% higher for Black persons.
Study context
- Population
- Adult out-of-hospital cardiac arrest (OHCA) patients in the US National EMS Information System database, 2021 (excluding EMS-witnessed, traumatic, healthcare-setting or wilderness arrests and DNR orders)
- Participants
- 207,134 patients
- Exposure
- Patient race/ethnicity vs White patients
- Outcome
- Association between race/ethnicity and odds of lay-rescuer AED placement for OHCA
Methodological detailsretrospective, multiple logistic regression adjusted for known covariates
- Retrospective
- Multiple logistic regression adjusted for known covariates
