Cardiac arrest & resuscitation
Agency factors associated with first response systems that improve out-of-hospital cardiac arrest outcomes
Authors' conclusion
FR AED more commonly had a positive association with outcomes than FR CPR. Agencies with better outcomes from FR interventions treated more OHCAs and had lower rates of FR intervention.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCAs) in the national Cardiac Arrest Registry to Enhance Survival (CARES) registry, 2016–2021
- Exposure
- Positive association vs No/inverse association
- Outcome
- Survival with favorable neurologic status
Methodological detailsnational registry (CARES), agency-level logistic regression
- National registry (CARES)
- Agency-level logistic regression
