The Mortality Probability Models (MPM II) can be used for predicting the mortality of patients in the ICU and for comparing the care received in different intensive care units.
Features of MPM assessments:
(1) multiple diagnoses can be included, rather than a single, most severe condition
(2) adjustments made in conditions considered and weightings given at admission and during hospitalization, reflecting differing impact on mortality

Use in quality assessment of ICU care:
• The MPM-0 is independent of ICU care, while later MPM scores are affected by care received.
