(Mortality Probability Models)
Variables (Help) Values (1 if yes, 0 otherwise) Beta
Coma (Glasgow 3-5) at 48 h (Help)
Coma (Glasgow 3-5) at admission (Help)
Emergency admission
Prothrombin time > N + 3 sec
(Measures in the period 24- 48 h)
Cancer part of present problem
Infection confirmed at 48 h
FIO2 > O.5
(Measures in the period 24- 48 h)
Urine output < 150 mL / 8 h
(Measures in the period 24- 48 h)
Total hours of i.v. vasoactive drugs Logit =
Logit = Sum ( values * beta) + age * 0.042383 + Hours of ventilation * 0.021409 + Hours of drugs* 0.017262 - 5.8601
Predicted death rate =
(eLogit) / (1 + eLogit)
