New EuroSCORE II (2011)

Logistic 1. Notes about euroSCORE II. [1] 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 [2] . 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. [2] 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 ( claudication carotid occlusion or >50% stenosis amputation for arterial disease previous or planned intervention on the abdominal aorta, limb arteries or carotids. [4] Poor mobility - severe impairment of mobility secondary to musculoskeletal or neurological dysfunction.
