The European Centre for Disease Prevention and Control (ECDC) reports that the burden of healthcare-associated C. difficile infection (CDIs) in acute care hospitals in the EU/EEA was estimated at 123.997 cases annually1. In the ECDC point prevalence survey of healthcare-associated infections (HAIs) and antimicrobial use in European acute care hospitals 2011-2012, C. difficile was the 8th most frequently detected microorganism among HAIs. Using a conservative figure of 3% attributable mortality, the number of deaths occurring as the direct consequence of healthcare-associated CDI can be estimated at 3.700 per year in the EU/EEA.
