(Mortality Probability Models)
Variables (Help) Values (1 if yes, 0 otherwise) Beta
Date of measure
Medical or unscheduled surgery admission
Metastatic neoplasm
Cirrhosis
Creatinine > 2.0 mg/dL ( > 177 micromol/L)
Urine output < 150 mL / 8 hours
Coma (Glasgow 3-5) (Help)
Confirmed infection
Intracranial mass effect
Mechanical ventilation
Vasoactive drugs > = 1 hour
PaO2 < 60 mmHg ( < 7.98 kPa )
Prothrombin Time > standard + 3 sec
Age + 0.03268
Predicted Death rate :

... .... . . .

 Logit =
Logit = Sum ( values * beta) + age * 0.03268 -(5.64592 if MPM 24) - (5.392 if MPM 48) - (5.238 if MPM 72 )
Predicted Death Rate= (eLogit) / (1 + eLogit)
