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

Abstract

Spanish cardiac surgical patients have a high-risk profile. Areas under the ROC curve show good discrimination for both models. Predicted mortality using EuroSCORE II more closely matches actual mortality than that predicted by the original EuroSCORE. Both models show statistically significant differences from the actual mortality rate, with EuroSCORE overpredicting and EuroSCORE II underpredicting mortality. The funnel plot illustrates risk-adjusted mortality clearly out of boundaries when EuroSCORE is used, and near underprediction when the reference is EuroSCORE II.
