Multicenter external validation of the FW-TRIC score for predicting red blood cell transfusion in on-pump cardiac surgery
Authors' conclusion
The FW-TRIC score was externally validated as a robust and generalizable preoperative tool for predicting perioperative RBC transfusion in on-pump cardiac surgery.
Study context
- Population
- Adults undergoing on-pump cardiac surgery at nine cardiovascular centres in China, January–December 2024 (excluding transplantation, mechanical circulatory support, preoperative transfusion)
- Participants
- 3,287 adults · 9 centres
- Outcome
- Discrimination (ROC AUC) and calibration of the FW-TRIC score for predicting perioperative RBC transfusion
Performance
As reported in the abstract
Prediction of perioperative RBC transfusion
| Test or model | AUC |
|---|---|
| FW-TRIC score | 0.713 (95% CI, 0.696-0.731) |
FW-TRIC score
AUC0.713 (95% CI, 0.696-0.731)
- Overall perioperative red blood cell (RBC) transfusion rate
- 40.1%
Further findings
Individual predictors vs FW-TRIC score
- All individual predictors (age, sex, NYHA class, body surface area, previous cardiac surgery, emergency surgery, surgery type) underperformed the FW-TRIC score
- all P < 0.05
Performance by centre
- Performance remained good across all nine centres
- AUCs > 0.65
