Good-quality bystander CPR triples OHCA survival
Paramedic-assessed quality of bystander CPR is associated with survival in out-of-hospital cardiac arrest
Resuscitation · Added 23 August 2026
NSW registry study (n=17,715) found any bystander CPR increased 30-day survival odds by 70%, but good-quality bystander CPR more than tripled odds (aOR 2.62) while poor-quality CPR showed no benefit.
- Study type
- Registry
- Design
- Population-based registry cohort study
- Participants
- 17,715 patients with OHCA
- Main finding
- Bystander CPR increased 30-day survival odds (aOR 1.70, 95% CI 1.24-2.34); good-quality CPR aOR 2.62 (95% CI 1.86-3.68); poor-quality CPR no benefit (aOR 0.99, 95% CI 0.68-1.45).
- Caveat
- Bystander CPR quality recorded in only 62.1% of cases and paramedic-assessed, so misclassification likely
- Bottom line
- Supports current practice
Why it matters in Australia (High relevance). Large Australian registry with direct relevance to dispatch-assisted CPR quality measurement and dispatcher coaching.
Learning goal
Strengthen my ability to assess bystander CPR quality and use it to guide resuscitation decisions.

Double sequential defibrillation shows no benefit
NZ EMS observational study (n=1,401) found no survival benefit after DSD implementation for refractory VF/VT, with lower ROSC odds in DSD patients likely reflecting confounding by indication.
