The original EuroSCORE has been replaced with a new model, EuroSCORE II in 2011. In this new version, an additional risk factor "Poor mobility" was added, while others, such as "Obesity" were omitted.
In comparison with other Cardiac Risk Scores, the previous EuroSCORE appeared to over-estimate the risk of death ("mortality is considerably overestimated by this score"). This new version has added a new Risk factor, "Poor mobility", but does not include others such as "Obesity". EuroSCORE is widely used in Europe and for this reason was added to our Risk Scores category.
Important: The previous additive 1 and logistic 2 EuroSCORE models are out of date. A new model has been prepared from fresh data and is launched at the 2011 EACTS meeting in Lisbon. The model is called EuroSCORE II 3 - this online calculator has been updated to use this new model. If you need to calculate the older "additive" or "logistic" EuroSCORE please visit the old calculator by clicking here.
Notes about euroSCORE II
 Age - in completed years. Some of the weighting for age is now incorporated into the renal impairment risk factor, so it is important that all risk factors are entered to give reliable risk estimations - see note . Of over 20,000 patients in the EuroSCORE database, only 21 patients were aged over 90 - therefore the risk model may not be accurate in these patients. Please exercise clinical discretion in interpreting the score. The oldest patient in the EuroSCORE database was 95 - EuroSCORE II is not validated in patients over this age.
 Renal impairment - there are now 3 categories based on creatinine clearance calculated using Cockcroft-Gault formula. Unlike serum creatinine in the old EuroSCORE model, some of the weighting for age is directly incorporated into this factor, as age is a component of creatinine clearance. The 3 categories are:
- on dialysis (regardless of serum creatinine level)
- moderately impaired renal function (50-85 ml/min)
- severely impaired renal function (<50 ml/min) off dialysis
* Weight (and creatinine) have not been directly included in the main EuroSCORE II calculator because they are not direct risk factors in the EuroSCORE II model, other than they contribute to creatinine clearance.
- carotid occlusion or >50% stenosis
- amputation for arterial disease
- previous or planned intervention on the abdominal aorta, limb arteries or carotids
 Poor mobility - severe impairment of mobility secondary to musculoskeletal or neurological dysfunction
 Critical preoperative state ventricular tachycardia or ventricular fibrillation or aborted sudden death, preoperative cardiac massage, preoperative ventilation before anaesthetic room, preoperative inotropes or IABP, preoperative acute renal failure (anuria or oliguria <10ml/hr)
- elective : routine admission for operation.
- urgent: patients who have not been electively admitted for operation but who require intervention or surgery on the current admission for medical reasons. These patients cannot be sent home without a definitive procedure.
- emergency: operation before the beginning of the next working day after decision to operate.
- salvage: patients requiring cardiopulmonary resuscitation (external cardiac massage) en route to the operating theatre or prior to induction of anaesthesia. This does not include cardiopulmonary resuscitation following induction of anaesthesia
- valve repair or replacement
- replacement of part of the aorta
- repair of a structural defect
- maze procedure
- resection of a cardiac tumour

- The manuscript which supports the new model is being submitted for publication. The new model has been validated by the EuroSCORE Project Group and awaits validation by users worldwide. It was presented at EACTS in Lisbon on 3rd October 2011.
