Accuracy of frailty instruments in predicting outcomes following perioperative cardiac arrest
Authors' conclusion
Incorporating frailty did not significantly improve predictive accuracy of models for 30-day mortality and non-home discharge following perioperative resuscitation.
Study context

- Exposure
- Baseline risk models vs baseline models plus frailty index
- Outcome
- Predictive accuracy (AUC-ROC, ICI, continuous NRI) for 30-day mortality and non-home discharge
- Follow-up
- 30 days
