A Prospective Multicenter Comparison of Trauma and Injury Severity Score, American Society of Anesthesiologists Physical Status, and National Surgical Quality Improvement Program Calculator’s Ability to Predict Operative Trauma Outcomes
Authors' conclusion
TRISS predicts mortality better than ASA-PS and NSQIP-SRC in trauma patients undergoing surgery within 24 hours. The TRISS mortality predictive ability is not improved when combined with ASA-PS or NSQIP-SRC. However, NSQIP-SRC was the most accurate predictor of LOS and complications.
Study context
- Population
- Trauma patients ≥18 years undergoing operation within 24 hours of admission
- Participants
- 1,213 patients · 4 level I trauma centers
- Exposure
- Mortality, length of stay (LOS) and complication prediction by TRISS, American Society of Anesthesiologists physical status (ASA-PS), National Surgical Quality Improvement Program Surgical Risk-Calculator (NSQIP-SRC) and their combinations
- Outcome
- Prediction of mortality (Brier score)
