The study by Ebell and colleagues makes an important contribution to our understanding of the outcomes of hospital cardiopulmonary resuscitation (CPR). Although most prior work has focused on predictors of survival, Ebell et al focused on predictors of a good outcome, which they define as survival to hospital discharge with minimal neurologic disability. In a large group of patients who underwent CPR, they developed and validated the Good Outcome Following Attempted Resuscitation (GO-FAR) score, a prognostic index that has solid accuracy. The GO-FAR score identifies a large proportion of patients (28.3%) who have a low or very low likelihood (<2%) of achieving the good outcome defined by the authors. The variables in this prognostic index are widely available, enhancing the ability to apply this model to most hospitalized patients.
