Cardiac arrest & resuscitation
Historical neighborhood redlining and bystander cardiopulmonary resuscitation (CPR) disparities in out-of-hospital cardiac arrest
Authors' conclusion
Redlining, a historical segregation practice, is associated with reduced contemporary rates of bystander CPR during OHCA.
Study context
- Population
- Witnessed non-traumatic out-of-hospital cardiac arrest (OHCA) in graded Home Owners' Loan Corporation (HOLC) census tracts, Cardiac Arrest Registry to Enhance Survival (CARES) registry, USwitnessed OHCA in graded tracts
- Participants
- 43,186 participants
- Exposure
- HOLC grades B, C, D vs HOLC grade A
- Outcome
- Bystander CPR provision
