Appendix 4: Management of Clostridium difficile associated diarrhoea


Risk factors for CDAD

Antibiotic Associated Diarrhoea (AAD) occurs in association with the administration of antibiotics. The spectrum of findings ranges from colitis to so-called 'nuisance' diarrhoea. Infection with Clostridium difficile accounts for only 10 to 20% of the cases of AAD, but it accounts for the majority of cases of colitis. Major risk factors for C. difficile infection include: advanced age, hospitalisation, exposure to antibiotics.

Some antibiotics are frequently implicated in C. difficile associated diarrhoea (CDAD) – e.g. Cephalosporins, Clindamycin, Quinolones and broad spectrum antibiotics, but virtually any antibiotic may be implicated, including brief courses e.g. surgical prophylaxis. Occasional cases follow chemotherapy treatments of cancer.
