Validation of the EuroSCORE II in a Greek Cardiac Surgical Population: A Prospective Study

G Stavridis et al. Open Cardiovasc Med J. .

Abstract

Objective: The objective of this study was to examine the validity of EuroSCORE II in the Greek population.

Methods: A prospective single-center study was performed during November 1, 2013 and November 5, 2016; 621 patients undergoing cardiac surgery were enrolled. The EuroSCORE II values and the actual mortality of the patients were recorded in a special database. Calibration of the model was evaluated with the Hosmer-Lemeshow goodness-of-fit test, and discrimination with the areas under the receiver operating characteristic (ROC) curve.

Results: The observed in-hospital mortality rate was 3% (i.e. 18/621 patients). The median EuroSCORE II value was 1.3% (1st quartile: 0.86%, 3rd quartile: 2.46%), which indicates a low in-hospital mortality. Area under the ROC curve for EuroSCORE II was 0.85 (95% CI: 0.75-0.94), suggesting very good correct classification of the patients.

Conclusion: The findings of the present work suggest that EuroSCORE II is a very good predictor of in-hospital mortality after cardiac surgery, in our population and, therefore can safely be used for quality assurance and risk assessment.

Keywords: Biostatistics; Cardiac surgery; EuroSCORE; Mortality; Risk estimation.
