Risk model choice alters surgeon outlier identification; leaves open whether local calibration improves fairness in cardiac surgery benchmarking.
Does the choice of risk-adjustment model (EuroSCORE vs locally derived) influence the outcome of surgeon-specific mortality analysis in adult cardiac surgery patients?
The choice of risk model significantly influences the identification of high mortality outcomes for individual surgeons, with uncalibrated EuroSCORE significantly overpredicting mortality.
