These data come from a large, multi-hospital study of adult patients with critical, acute conditions such as acute respiratory failure and multiple organ system failure. The primary outcome is time until death. A variety of potentially useful predictors, both demographic and lab values, are available. The primary goal of the study is to develop an algorithm for predicting survival in these patients.

: Number of days spent in the hospital prior to being admitted into the study. For many patients, this is 1 - they were entered into the study at the beginning of their stay in the hospital. Other patients, however, stayed in the hospital for days/week/months prior to their entry in the study.MAP
