EuroSCORE II

Estimates in-hospital mortality in adults undergoing cardiac surgery (revascularization, valves, thoracic aorta) using 18 patient, cardiac and operative factors.

Calculate with transparency

EuroSCORE II/Nashef 2012: logistic, intercept −5.324537, original coefficients; excludes EuroSCORE I

EuroSCORE II was developed for death in the original hospital after major cardiac surgery, with data collected in 2010. It is not EuroSCORE I and does not replace calibration in the current population or institution. Factor definitions, eligibility and time horizon must match the model; the probability does not ensure an individual outcome.
