Cardiac arrest & resuscitation
Outcome assessment for out-of-hospital cardiac arrest patients in Singapore and Japan with initial shockable rhythm
Authors' conclusion
This observational study found that the outcomes for patients with initial shockable rhythm but who did not obtain ROSC on hospital arrival in Singapore were lower than expected from Osaka.
Study context
- Population
- Adult (18–74 years) OHCA patients with initial shockable rhythmSG-PAROS, analysed
- Participants
- 1,789 participants
- Comparison
- SG-PAROS vs Osaka-CRITICAL
- SG-PAROSn = 1,789
- Primary endpoint
- Favorable neurological outcome:
- Observed vs risk-adjusted expected
- OE ratio

Primary result
As reported in the abstract
Favourable neurological outcome, observed vs expected (OE ratio) by status on hospital arrival
Return of spontaneous circulation (ROSC) on hospital arrival: OE ratio (95% CI); observed at the same level as expected
0.905
0.784–1.036
Continued cardiac arrest, shockable rhythm on hospital arrival: OE ratio (95% CI); lower than expected
0.369
0.258–0.499
Continued cardiac arrest, nonshockable rhythm on hospital arrival: OE ratio (95% CI); lower than expected
0.137
0.065–0.235
