Validation and quality measurements for EuroSCORE and EuroSCORE II in the Spanish cardiac surgical population: a prospective, multicentre study.

Objectives: Since its development in the late 1990s, the European System for Cardiac Operative Risk Evaluation (EuroSCORE) has been the predictive model of choice for estimating mortality after cardiac surgery. As outcomes from cardiac surgery improved, the EuroSCORE showed a loss of calibration, and a revised version of the model was developed, EuroSCORE II. The objectives of this study were to examine the validity of both scores in the Spanish population, and to depict the performance of both models on a funnel plot.
