A systematic review of 67 articles showed that the EuroSCORE overestimated early mortality overall, but the additive model underestimated mortality in high-risk patients.
Systematic Review
Does the EuroSCORE accurately predict early mortality in patients undergoing cardiac surgery?
The original EuroSCORE demonstrates poor calibration for early mortality after cardiac surgery, limiting its utility for patient selection and benchmarking.
The European system for cardiac operative risk evaluation (EuroSCORE) is a commonly used risk score for operative mortality following cardiac surgery. We aimed to conduct a systematic review of the performance of the additive and logistic EuroSCORE. A literature search resulted in 67 articles. Studies applying the EuroSCORE on patients undergoing cardiac surgery and which reported early mortality were included. Weighted meta-regression showed that the EuroSCORE overestimated mortality. However, this performance depended on the risk profile of patients: in high-risk patients, the additive model actually underestimated mortality. Discriminative performance was good. Given the poor predictive performance, the EuroSCORE may not be suitable as a tool for patient selection nor for benchmarking.
Siregar et al. (2012) conducted a systematic review in Cardiac surgery. EuroSCORE was evaluated on Early mortality. A systematic review of 67 articles showed that the EuroSCORE overestimated early mortality overall, but the additive model underestimated mortality in high-risk patients.
