Objective: To review the literature related to the treatment and infection control of Clostridium difficile-associated diarrhea (CDAD).
Data sources: A MEDLINE search (1966-August 2001) of the English literature was conducted.
Data synthesis: C. difficile is a leading cause of antibiotic-related diarrhea. The clinical spectrum extends from simple diarrhea to fulminant colitis. Cessation of antibiotic therapy alone is sufficient for mild cases; however, the majority of cases require oral metronidazole as the drug of choice. Vancomycin orally is reserved for patients who have failed to respond to metronidazole, are pregnant, or are severely ill. There is an important role for infection control interventions.
Conclusions: CDAD is a common infection. Appropriate antibiotic treatment and infection control policies can prevent the spread and reduce the morbidity associated with this disease.
