Cardiac arrest & resuscitation
Comparing outcomes of out-of-hospital cardiac arrest patients with initial shockable rhythm in Singapore and Osaka using population-based databases
Authors' conclusion
This study showed the outcomes of OHCA patients without prehospital ROSC in Singapore were worse than expected derived from Osaka data even using population-based databases.
Study context
- Population
- Adult OHCA patients with initial shockable rhythm
- Participants
- 2,905 vs 3,088
- Comparison
- Singapore vs Osaka
- Singaporen = 2,905
- Osakan = 3,088reference
- Primary endpoint
- Good neurological outcomes:
- OE ratio
- Singapore observed vs expected from Osaka
- Follow-up
- one-month
Methodological detailsmachine-learning-based prediction model, observed-expected ratio, subgroups by prehospital ROSC
- Machine-learning-based prediction model

Primary result
As reported in the abstract
One-month good neurological outcome, by prehospital ROSC (subgroup)
OE ratio
1.067
95% CI 1.012–1.125
with prehospital ROSC; adjusted for patient characteristics
OE ratio
0.238
95% CI 0.173–0.294
without prehospital ROSC; adjusted for patient characteristics
