Although a significant number of patients die after discharge from the ICU there is a paucity of data related to predicting hospital mortality based on information obtained at ICU discharge. It is likely that experienced intensivists may be able to predict the likelihood of hospital death at ICU discharge accurately if they incorporate patients age preferences regarding life support comorbidities prehospital quality of life and clinical course in the ICU into their prediction. However if it is to be generalizable and reproducible and to perform well without bias then a good prediction model should be based on objectively defined variables. Prognostic models are used to predict the outcome of patients admitted to the intensive care unit ICU . Age comorbidities physiologic abnormalities acute diagnoses and lead-time bias are among the predictor variables entered into these models. These variables are usually selected and scored subjectively by expert consensus or objectively using statistical methods. Some of the ICU prognostic models require cumbersome data collection and
