Acute cardiac care & resuscitation
Social determinants and pre-arrest care patterns associated with cardiac arrest and mortality
Authors' conclusion
SDOH have a significant impact on the risk of CA, pre-arrest care patterns, and post-arrest mortality.
Study context
- Population
- ED encounters for cardiac arrest (ICD-10-CM I46), national EHR database (Epic Cosmos, 227 million patients), April 2020–April 2023ED visits for CA
- Participants
- 201,846 participants
- Exposure
- CA incidence across demographics and social determinants
- Outcome
- Difference in CA incidence between groups (odds ratios (ORs))
Main finding
As reported in the abstract
CA incidence
- Males vs Females · all ages
- OR 1.76; P < 0.0001
- Black vs White
- adjusted OR 1.85; P < 0.0001
- Native Hawaiian or Pacific Islander vs White
- adjusted OR 1.44; P < 0.0001
- American Indian or Alaska Native vs White
- adjusted OR 1.51; P < 0.0001
- Asian vs White
- adjusted OR 0.81; P < 0.0001
- Hispanic/Latino
- adjusted OR 0.72; P < 0.0001
- Highest social vulnerability index (SVI) quartile vs Lowest SVI quartile
- adjusted OR 1.71; P < 0.0001
- Overall CA incidence
- 0.11%
Observational data: associations, not effects.
Secondary outcomes
Pre-arrest care within 30 days
- Significant heterogeneities in pre-arrest care; ED visits more common than office visits among male, highest SVI, Hispanic/Latino and minority patients, except Asian patients
Post-arrest mortality · after 30 days
- Highest in females, Black patients and highest SVI
