Performance Comparison of Pulmonary Risk Scoring Systems in Lung Resection
Authors' conclusion
None of the scoring systems appeared to have adequate discriminatory power to predict PPCs among patients undergoing lung resection.
Study context
- Population
- Adults undergoing lung resection surgery under 1-lung ventilation123 postoperative pulmonary complications (PPCs) (5.9%)
- Participants
- 2,104 adults
- Exposure
- ARISCAT vs LAS VEGAS vs SPORC vs CARDOT pulmonary risk scores
- Outcome
- Discrimination for PPCs (c-index)
Methodological detailssingle-centre, validation of risk scores
- Single-centre
- Validation of risk scores

Discrimination with predicted postoperative forced expiratory volume (ppoFEV1) added (c-index)
- Inclusion of ppoFEV1 slightly improved performance
Calibration (LOESS intercept)
- Slight overestimation
