Cardiac arrest & resuscitation
The incidence and outcomes of out-of-hospital cardiac arrest in metropolitan versus rural locations: A systematic review and meta-analysis
Authors' conclusion
Overall, while incidence did not vary, the odds of OHCA survival to hospital discharge were approximately 50% lower in rural areas compared to metro areas.
Study context
- Population
- Ambulance-attended out-of-hospital cardiac arrest (OHCA) in metropolitan and rural areas28 studies (30 papers)
- Participants
- 823,253 participants
- Comparison
- Rural vs metropolitan locations
- Outcome
- Cumulative incidence and survival (return of spontaneous circulation, survival to hospital discharge or to 30 days)
Methodological details28 studies from 13 countries; definition of rurality varied markedly
- 28 studies from 13 countries; definition of rurality varied markedly
Pooled result
As reported in the abstract
Rural vs MetroOdds ratio (95% CI)
ROSC on arrival at hospital; I2 = 89%; 5 studies; 90,934 participants
0.53(0.40–0.70)
Survival to hospital discharge/30 days; I2 = 95%; 15 studies; 18,837 participants
0.52(0.38–0.71)
