The EuroSCORE as predictor for prolonged hospital and intensive care stay after cardiac surgery?

Objective: Validation of the EuroSCORE as predictor for a prolonged hospital and intensive care stay after CABG vs. institution-specific scoring systems.

Methods: For the evaluation of a prolonged hospital stay, 3359 patients were included in the analysis of EuroSCORE vs. the CORRAD morbidity score. For a prolonged intensive care stay, 1638 patients were included in the analysis of the EuroSCORE vs. the PICUS score.

Results: There was no significant difference in hospital stay between the three different EuroSCORE risk groups. The difference in hospital stay between the high-risk and low-risk groups, identified by the CORRAD morbidity score, was significant (6.9 vs.11.2 days). For a prolonged intensive care stay, the patients identified as high risk by the EuroSCORE and by the PICUS score also had a significantly longer intensive care stay; however, the discriminatory power was low.

Conclusion: The EuroSCORE is not of value as a predictive system for a prolonged hospital stay. There is a relation between the high-risk patients identified by the EuroSCORE and a prolonged intensive care stay.
