Cardiac arrest & resuscitation
Effect of cardiopulmonary resuscitation training for layperson bystanders on outcomes of out-of-hospital cardiac arrest: A prospective multicenter observational study
Authors' conclusion
This study demonstrated that CPR training for laypersons was associated with increased ROSC rates in OHCA patients
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) patients who received bystander cardiopulmonary resuscitation (CPR) from a layperson, Japan
- Participants
- 969 patients
- Exposure
- CPR-trained layperson bystanders vs untrained layperson bystanders
- CPR-trainedn = 322
- Controln = 647reference
- Outcome
- ROSC rate
Methodological detailsmulticentre, 42 centres in Japan, propensity score with inverse probability treatment weighting (IPTW)
- Multicentre
- 42 centres in Japan
- Propensity score with IPTW
Main finding
As reported in the abstract
- CPR-trained vs Control: P = 0.02
- IPTW-adjusted
Observational data: associations, not effects.
Secondary outcomes
ROSC rate, before adjustment · unadjusted
P < 0.01
| Outcome | P value |
|---|---|
| Pre-hospital ROSCAfter IPTW adjustment · IPTW-adjusted | P < 0.01 |
| ROSC after hospital arrivalAfter IPTW adjustment · IPTW-adjusted | P = 0.04 |
All secondary outcomes, before adjustment
- All secondary outcomes significantly improved in the trained group before adjustment
Favourable neurological outcomes and 30-day survival
- No differences in neurological outcomes and 30-day survival
