Cardiac arrest & resuscitation
Paramedic-assessed quality of bystander CPR is associated with survival in out-of-hospital cardiac arrest
Authors' conclusion
Quality of bCPR is of greater importance than the fact that bCPR was performed.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) cases, NSW Ambulance OHCA registry, 2021–2024
- Participants
- 17,715 cases
- Exposure
- Bystander CPR vs no bystander CPR
- Outcome
- 30-day survival
- Follow-up
- 30 days
Methodological detailsmultivariate models
- Multivariate models
Main finding
As reported in the abstract
Each group vs no bCPRAOR for 30-day survival (95% CI)
bCPR
1.70(1.24–2.34)
Good-quality bCPR
2.62(1.86–3.68)
Poor-quality bCPR
0.99(0.68–1.45)
Observational data: associations, not effects.
Further findings
Bystander CPR (bCPR) performance and quality recording
- bCPR performed
- 59.4%
- bCPR quality recorded
- 62.1%
Factors associated with bCPR being performed and its quality
- Younger age, witnessed arrest and non-residential location associated with increased odds of bCPR being performed and being of good quality
- Male sex and EMS response time <10 min associated with lower odds of bCPR being performed but not with bCPR quality
