Description

The MPM II estimates the probabaility of hospital mortality at 24, 48, and 72 hours in the intensive care unit. Reference: Lemeshow, S., Klar, J., Teres, D., Avrunin, J. S., Gehlbach, S. H., Rapoport, J., & Rué, M. (1994). Mortality probability models for patients in the intensive care unit for 48 or 72 hours: a prospective, multicenter study. Critical care medicine, 22(9), 1351-1358.

Probabilities of hospital mortality
Description

Probabilities of hospital mortality

Probability of hospital mortality at 24 hrs
Description

beta0 24 hrs = -5.64592. The logit is calculated as the sum of the constant term (beta0) plus the products of the values of each of the 13 model variables by its associated beta0 (i.e. Logit=beta0 + beta1*x1 + ... + beta13*x13). Predicted Death Rate= (eLogit) / (1 + eLogit).

Probability of hospital mortality at 48 hrs
Description

beta0 48 hrs = -5.39153. The logit is calculated as the sum of the constant term (beta0) plus the products of the values of each of the 13 model variables by its associated beta0 (i.e. Logit=beta0 + beta1*x1 + ... + beta13*x13). Predicted Death Rate= (eLogit) / (1 + eLogit).

Probability of hospital mortality at 72 hrs
Description

beta0 72 hrs = -5.23840. The logit is calculated as the sum of the constant term (beta0) plus the products of the values of each of the 13 model variables by its associated beta0 (i.e. Logit=beta0 + beta1*x1 + ... + beta13*x13). Predicted Death Rate= (eLogit) / (1 + eLogit).
