Background & objectives: Clostridium difficile infection is one of the most common healthcare-associated infections worldwide. Recent epidemiologic studies have suggested that statin users may have a lower risk of C. difficile infection, although the results are inconsistent. This meta-analysis was conducted with the aim of summarizing all available data to assess the risk of C. difficile infection among statin users versus non-users. Methods: A literature review was performed using the MEDLINE and EMBASE databases from inception to October 2017. Cohort, case-control and cross-sectional studies that compared the risk of C. difficile infection among statin users versus non-users were included. Pooled odds ratio (OR) and 95 per cent confidence interval (CI) were calculated using a random-effect, generic inverse variance method. Results: Six case-control studies and two cross-sectional studies met the eligibility criteria and were included in this meta-analysis. The risk of C. difficile infection among statin users was significantly lower than non-users with the pooled OR of 0.74 (95% CI, 0.61-0.89). The statistical heterogeneity of this study was high (I[2]=90%). Interpretation & conclusions: This meta-analysis demonstrated a decreased risk of C. difficile infection among statin users versus non-users. Further studies are required to clarify the role of statins for prevention of C. difficile infection in clinical practice.
