Scoring systems for ICU and surgical patients:

MPM - 24h 
(Mortality Probability Models)


Variables (Help) Values (1 if yes, 0 otherwise) Beta
Coma (Glasgow 3-5) (Help)
Cancer part of present problem
Emergency admission
Probable shock
Urine output < 150 mL / 8 h
Infection confirmed
Prothrombin time > N + 3 sec
Creatinine > 2.0 mg/dL ( >177 micromol/L)
PaO2 < 60 mmHg ( < 7.98 kPa )
FIO2 > O.5
Surgical service at 24 h
Number of lines (Help) Logit =
Logit = Sum ( values * beta) + age * 0.044142 + Hours * 0.026336 + Lines * 0.15376 - 6.5288
Predicted death rate = (eLogit) / (1 + eLogit)
Hours of mechanical ventilation
Age
