How to calculate the logistic EuroSCORE
Roques F, Michel P, Goldstone AR, Nashef SA. The logistic EuroSCORE. Eur Heart J. 2003 May;24(9):882-3
Using the same risk factors as the additive model, the logistic regression version of the score (the “logistic EuroSCORE”) can be calculated. For a given patient, the “logistic EuroSCORE” which is the predicted mortality according to the logistic regression equation, can be achieved with the following formula:
Predicted mortality = e (βo + åbi Xi) / 1+ e (βo + åbi Xi)
e is the natural logarithm = 2.718281828...
βo is the constant of the logistic regression equation = -4.789594
βi is the coefficient of the variable Xi in the logistic regression equation provided in the table below.
Xi = 1 if a categorical risk factor is present and 0 if it is absent
For age, Xi = 1 if patient age < 60; Xi increase by one point per year thereafter;
hence for age 59 or less Xi = 1, age 60 Xi = 2, age 61 Xi = 3, and so on.
Cardiologists and cardiac surgeons will be relieved to note that they do not have to face this complex calculation with every patient.
EuroSCORE (additive and logistic) can be calculated with ease using the online calculator on the EuroSCORE website.
