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:

* 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.

Extracardiac
arteriopathy - one or more of the following
[4] Poor mobility - severe impairment of mobility secondary to musculoskeletal or neurological dysfunction
[5]
Chronic lung
disease - long term use of bronchodilators or steroids for lung
disease
[6] Active endocarditis - patient still on antibiotic treatment for endocarditis at time of surgery
[7] 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)
[8] CCS class 4 angina angina at rest
[9] Recent MI myocardial infarction within 90 days
[10] Pulmonary
hypertension systolic pulmonary
artery pressure, now in 2 classes
[11]
Urgency
now four classes:
