Scoring systems for ICU and surgical patients:

ODIN (Organ Dysfunctions and / or INfection) 


Dysfunctions Variables Values (1 if yes, 0 otherwise) Beta Points
Respiratory PaO2 < 60mmHg (FiO2=0,21)
or:
Need for ventilatory support
Cardiovascular
(in the absence of hypovolemia with CVP< 5 mmHg) 		Systolic Arterial Pressure < 90 mmHg with signs of peripheral hypoperfusion
or :
Continuous infusion of vasopressor or inotropic agent to maintain SBP > 90 mmHg
Renal
(excluding chronic dialysis) 		Serum creatinine > 300 micromol /L
or :
Urine output < 500mL/24 h or <180 mL/8 h
or :
Need for hemodialysis or peritoneal dialysis
Neurologic Glasgow < 6 (in absence of sedation at any time in the day)
or :
Sudden onset of confusion or psychosis
Hepatic Serum bilirubin > 100 micromol /L
or :
Alkalines phosphatases > 3 x N
Hematologic Hematocrit < = 20%
or:
WBC < 2.000 /mm3
or :
Platelet Count < 40.000 /mm3
Infection
(with clinical evidence of infection) 		2 positive blood cultures
or :
Presence of gross pus in a closed space
or :
Source of the infection determined during hospitalization or at autopsy in case of death within the 24 h

(Score is recorded within the first 24 hours of admission)
Predicted Death Rate :
Logit = -3.59 + Sum (values*beta)
Predicted death rate =
e(Logit) / (1 + e (Logit)) 		ODIN :
 ODIN = Sum (points)
