EuroSCORE (Logistic) Calculator

Estimate operative mortality using the original EuroSCORE I logistic equation. For context, the page also displays the additive EuroSCORE group.

Legacy model
Important: EuroSCORE II is the current version for contemporary clinical use. This page implements the original logistic EuroSCORE I for historical, research, and comparison purposes.
Patient-related factors
Age is entered in completed years.
The model uses a threshold above 200 µmol/L (or about 2.26 mg/dL).
%
The model uses good >50%, moderate 30–50%, and poor <30%.
Pulmonary hypertension is counted when systolic PA pressure is above 60 mmHg.
Cardiac-related factors
Operation-related factors

What is EuroSCORE (Logistic)?

EuroSCORE is a cardiac surgery risk model designed to estimate the probability of operative mortality based on patient, cardiac, and procedure-related factors.

This page uses the original logistic version of EuroSCORE I and also shows the additive group for quick context.

Why use it?

  • It helps frame preoperative risk discussions.
  • It summarizes multiple major operative risk factors into one estimate.
  • It is still useful for legacy comparison, audit, and research contexts.

Limits and cautions

  • This is not a diagnosis and should not replace specialist judgment.
  • EuroSCORE I is an older model and may overestimate risk in modern practice.
  • Use EuroSCORE II for contemporary clinical assessment whenever appropriate.

Practical definitions used here

  • Creatinine is counted only when it exceeds 200 µmol/L.
  • Pulmonary hypertension is counted only when systolic PA pressure exceeds 60 mmHg.
  • Emergency means surgery before the beginning of the next working day.
