Antimicrobial selection and its impact on the incidence of Clostridium difficile-associated diarrhea.
The study objective was to determine which antimicrobials place patients at a higher risk for Clostridium difficile-associated diarrhea (CDAD) and which interventions can reduce their risk. All patients with diarrhea and a positive toxin assay for Clostridium difficile for 3 months were included in the study. Patients were broken down into either community-acquired infection or health care-associated infection based on symptom onset, antibiotic usage prior to admission, and where the patient was admitted from. Physicians were educated on antimicrobials that place patients at higher risk for CDAD and alternative agents to use. Physician education consisted of in-service presentations, posters, Medical Grand Rounds, and an article in the physician newsletter highlighting the initial results of this study and alternative antimicrobial regimens. After implementation of educational programs, a repeat sample of patients was reviewed to determine effectiveness of the physician education. Cases of CDAD increased secondary to testing changes at our facility. Implicated antimicrobial usage did decrease after educational program implementation.
