Prevalence of Clostridium difficile on a mixed-function ward for the elderly.

We studied the prevalence of Clostridium difficile over a period of 2 months on a mixed-function geriatric ward. Seven (14%) of the 49 patients were long-stay but the remainder were in hospital for acute illness or required a short period of active rehabilitation. Although 69% patients had recently received antibiotics, from only two (4%) was C. difficile isolated from their faeces. Our results show that C. difficile is not endemic in patients on all geriatric wards as has been previously suggested.
