Clostridium difficile Infections: Diagnosis, Treatment, and Prevention
Searching for relevant literature was conducted in MEDLINE, the Cochrane Library, and Allied and Complementary Medicine (AMED). ClinicalTrials.gov and expert consultants provided leads to additional studies. Reference lists from relevant literature were also manually searched. Standard Evidence-based Practice Center methods were employed. Screening of abstracts and full text articles to identify studies meeting inclusion/exclusion criteria was performed by two independent reviewers. High-quality direct comparison studies were used to examine differences in diagnostic tests. Randomized controlled trials (RCTs) were used to examine comparative effectiveness of antibiotic treatment for CDI. Quality of data extraction was checked by separate reviewers. Quality ratings and strength of evidence grading was performed on included studies. Evidence on diagnostic tests was quantitatively synthesized focusing on differences between test sensitivities and specificities. Evidence on antibiotic treatment was quantitatively examined using pooled analysis. Qualitative narrative analysis was used to synthesize evidence from all available study types for environmental prevention and nonstandard prevention and treatment, with the exception of probiotics as primary prevention.
