Hypervirulent Clostridium difficile strains, most notably BI/NAP1/027, have been increasingly emerging in Western countries as local epidemics. We performed a prospective multicentre observational study from December 2011 to May 2012 to identify recent incidences of toxigenic culture-confirmed hospital-onset C. difficile infections (CDI) and their associated clinical characteristics in South Korea. Patients suspected of having been suffering from CDI more than 48 h after admission and aged ≥20 years were prospectively enrolled and provided loose stool specimens. Toxigenic C. difficile culture (anaerobic culture+toxin A/B/binary gene PCR) and PCR ribotyping were performed in one central laboratory. We enrolled 98 toxigenic culture-confirmed CDI-infected patients and 250 toxigenic culture-negative participants from three hospitals. The incidence of toxigenic culture-confirmed hospital-onset CDI cases was 2.7 per 10,000 patient-days. The percentage of severe CDI cases was relatively low at only 3.1%. UK ribotype 018 was the predominant type (48.1%). There were no hypervirulent BI/NAP1/027 isolates identified. The independent risk factors for toxigenic culture-confirmed hospital-onset CDI were invasive procedure (odds ratio (OR) 7.3, P=0.003) and past CDI history within 3 months (OR 28.5, P=0.003). In conclusion, the incidence and severity of CDI in our study were not higher than reported in Western countries.
