Extended-age Out-of-sample Validation of Risk Stratification Index 3.0 Models Using Commercial All-payer Claims
Authors' conclusion
Similar predictive performance in Medicare and in younger and healthier populations indicates that Risk Stratification Index 3.0 models are valid across a broad range of adult hospital admissions.
Study context
- Population
- Surgical and medical hospital admissions, younger and healthier 2017 Utah and Oregon state populations (All Payer Claims)
- Comparison
- Utah vs Oregon
- Outcome
- Performance of Risk Stratification Index 3.0 models (unplanned admissions, in-hospital mortality, AKI, sepsis, pneumonia, respiratory failure, major cardiac complications)
Methodological detailsout-of-sample validation, retrospective claims data
- Out-of-sample validation
- Retrospective claims data
Performance
As reported in the abstract
| Test or model | Admissions | Patients | Calibration R2 | Mean sensitivity, highest 5% risk |
|---|---|---|---|---|
| Utah | 55,109 | 40,710 | 0.93 (0.84 to 0.97) | 28% (17 to 44) |
| Oregon | 21,213 | 16,951 | 0.85 (0.71 to 0.91) | 37% (20 to 56) |
