Scoring systems for ICU and surgical patients:

Logistic EuroSCORE
(European System for Cardiac Operative Risk Evaluation : Logistic Regression Model)

Variables (Help)	Value : 1 if yes, 0 otherwise (except for age and LVEF)	Beta
Female gender	Yes
Emergency	Yes
Serum creatinine > 200 µmol/ L	Yes
L.V.E.F.	< 30 % 30 - 50 % > 50 %
C.O.P.D.	Yes
Surgery on thoracic aorta	Yes
Extracardiac arteriopathy	Yes
Neurological dysfunction	Yes
Active endocarditis	Yes
Critical preoperative state	Yes
Unstable angina	Yes
Recent myocardial infarction	Yes
Systolic PAP > 60 mmHg	Yes
Previous cardiac surgery	Yes
Postinfarct. septal rupture	Yes
Other than isolated C.A.B.G.	Yes
Age		0.0666354
Predicted Death Rate :		Logit = -4.789594 + Sum (values*beta) +age*(0.0666354 per year up to 59) Predicted death rate = e(Logit) / (1 + e (Logit))

Definitions

COPD : longterm use of bronchodilators or steroids for lung disease.
Extracardiac arteriopathy : any one or more of the following: claudication, carotid occlusion or > 50% stenosis, previous or planned intervention on the abdominal aorta, limb arteries or carotids.
Neurological dysfunction : disease severely affecting ambulation or day-to-day functioning.
Previous cardiac surgery : requiring opening of the pericardium.
Active endocarditis : patient still under antibiotic treatment for endocarditis at the time of surgery.
Critical preoperative state : any one or more of the following : ventricular tachycardia or fibrillation or aborted sudden death, preoperative cardiac massage, preoperative ventilation before arrival in the anaesthetic room, preoperative inotropic support, intraaortic balloon counterpulsation or preoperative acute renal failure (anuria or oliguria , 10 mL/h).
Unstable angina : rest angina requiring IV nitrates until arrival in the anaesthetic room.
Emergency : carried out on referral before the beginning of the next working day.
Surgery on thoracic aorta : for disorder of ascending, arch, or descending aorta.
Other than isolated C.A.B.G. : major cardiac procedure other than or in addition to C.A.B.G.
