Probiotics in the Prevention of Clostridium Difficile Associated Diarrhea in the Acute Care Setting

Abstract

Specific Aims: Clostridium difficile associated diarrhea (CDAD) frequently occurs in patients exposed to broad-spectrum antibiotics which can result in a life threatening illness. The role of probiotics in the prevention of CDAD is not well established and many medical centers across the United States are opting to remove probiotics from common CDAD prophylaxis. We aim to evaluate the efficacy of lactobacillus probiotics during the use of broad-spectrum antibiotic therapy in the acute care setting for the prophylaxis of CDAD at Kindred Hospital. Methods: We performed a single center, retrospective data analysis efficacy trial of inpatients receiving beta-lactam, fluoroquinolone or clindamycin antibiotics from the Kindred Hospital database. Two study groups will be compared: patients who received lactobacillus probiotic therapy based on protocol since May 2011 and patients who did not receive probiotic therapy. The presence or absence of CDAD will be used to evaluate probiotic efficacy. Main Results: Of the ### patients screened, ## were assigned to the treatment group and ## were assigned to the non-treatment group, a total of ## patients were analyzed for the primary endpoint. CDAD occurred in ## patients (xx%) receiving probiotic therapy while CDAD occurred in ## patients (xx%) not receiving probiotic therapy (relative risk [RR]: xx.x; p=0.xxx). Conclusion: [Anticipated] We identified no statistically significant evidence that the use of lactobacillus was effective in the prevention of CDAD. Further knowledge of the pathophysiology of CDAD and proper antibiotic use is needed for future studies.
