An Outbreak of Severe Clostridium difficile –Associated Disease Possibly Related to Inappropriate Antimicrobial Therapy for Community-Acquired Pneumonia

Abstract

We report a severe outbreak of Clostridium difficile infection. According to a chart review, half of the patients who received treatment for bacterial pneumonia before they developed C. difficile infection may not have had pneumonia. Excessive use of the hospital's new pneumonia care plan during the influenza season may have contributed to the intensity of this outbreak.
