Survival outcomes after cardiac or respiratory arrest occurring outside of intensive care units (ICUs) has been well described. We investigated survival outcomes of adults whose arrest occurred in ICUs and determined predictors of decreased survival. ⋯ Our study showed no major improvement in survival following cardiac arrest with pulseless electrical activity or asystole as the presenting rhythm in the ICU despite many advances in critical care over the previous two decades. The independent predictors of death within 24 hours after arrest in an ICU were sex, the presenting rhythm and the duration of CPR. Predictors of later death (eight months or more after arrest) were age and duration of CPR.

Anthropometric-based classification schemes for excess adiposity do not include direct assessment of obesity-related comorbidity and functional status and thus have limited clinical utility. We examined the ability of the Edmonton obesity staging system, a 5-point ordinal classification system that considers comorbidity and functional status, in predicting mortality in a nationally representative US sample. ⋯ The Edmonton obesity staging system independently predicted increased mortality even after adjustment for contemporary methods of classifying adiposity. The Edmonton obesity staging system may offer improved clinical utility in assessing obesity-related risk and prioritizing treatment.
