A predictive model of mortality in heart failure may be useful for clinicians to improve communication with and care of hospitalized patients. This study identified predictors of mortality and developed and validated a model using information available at hospital presentation. The project was a retrospective study of 4031 community-based patients presenting with heart failure at 34 hospitals in Ontario, Canada (2624 patients in the derivation cohort from 1999-2001 and 1407 patients in the validation cohort from 1997-1999), who had been identified as part of the Enhanced Feedback for Effective Cardiac Treatment (EFFECT) study.
