Perioperative medicine & outcomes
External Validation and Comparison of a General Ward Deterioration Index Between Diversely Different Health Systems
Authors' conclusion
PICTURE was able to identify general ward patients at risk of deterioration at both hospitals with consistent performance (AUROC and AUPRC) and compared favorably to existing metrics.
Study context
- Population
- General ward encounters at an academic medical center and a community hospital
- Participants
- 165,018 vs 11,083
- Comparison
- PICTURE deterioration index at an academic medical center vs a community hospital; vs Epic Deterioration Index and National Early Warning Score
- First hospitaln = 165,018
- Second hospitaln = 11,083
- Outcome
- PICTURE performance
Methodological detailsexternal validation, retrospective, two hospitals
- External validation
- Retrospective
- Two hospitals

As reported in the abstract
| Test or model | AUROC | Area under the precision-recall curve (AUPRC) |
|---|---|---|
| First hospital | 0.870 (95% CI, 0.861-0.878) | 0.298 (95% CI, 0.275-0.320) |
| Second hospital | 0.875 (0.851-0.902) | 0.339 (0.281-0.398) |
