Clostridium difficile infection increases acute and chronic morbidity and mortality.
The goal of this study was to quantify short- and long-term outcomes of Clostridium difficile infection in the elderly, using 2011 Medicare claims data. The claims records of 174,903 patients coded for Clostridium difficile infection were compared with those of 1,318,538 control patients. The authors concluded that Clostridium difficile infection was associated with increased risk of short- and long-term adverse outcomes, including transfer to short- and long-term care facilities, hospitalization, and all-cause mortality.

Identification of Medicare recipients at highest risk for Clostridium difficile infection in the US by population attributable risk analysis.
This study determined the population attributable risk percent (PAR%) for Clostridium difficile infection (CDI) in various subpopulations in the Medicare 5% random sample. It found that small and identifiable subpopulations that account for relatively large proportions of CDI cases in the elderly were identified. These data can be used to target specific subpopulations for CDI prevention interventions.
