EuroSCORE model I (logistic) - Evidencio
EuroSCORE model I (logistic)
Calculates the predicted operative mortality for patients undergoing cardiac surgery (c-index: 0.79).

Note: This model was published in 2003. An improved version of the EuroSCORE model (EuroSCORE II) was published in 2012.

Conditional information

The logistic EuroSCORE I was first published by Roques et al in 2003 as an improved version of the additive EuroSCORE I model1 published in 1999. The logistic model was found suitable for individual risk prediction, including very high risk patients.2 

In 2012, the EuroSCORE II model3 was published by Nashef et al. Risk-adjusted mortality ratio (RAMR = observed/predicted) for the previous EuroSCORE I additive model was 0.67 and for the previous logistic model 0.53. This suggests that the original EuroSCORE I is no longer appropriately calibrated, although both the old logistic and additive EuroSCORE I models were found to retain good discrimination. 

Model performance: 
The area under the ROC curve (discriminative power) of the logistic EuroSCORE I model was 0.79, indicating good discrimination.3 Therewith, its discriminative power is slightly but not significantly worse compared to the EuroSCORE II model.
