No. 275-Antibiotic Prophylaxis in Gynaecologic Procedures.

OBJECTIVE: To review the evidence and provide recommendations on antibiotic prophylaxis for gynaecologic procedures.

OUTCOMES: Outcomes evaluated include need and effectiveness of antibiotics to prevent infections in gynaecologic procedures.

EVIDENCE: Medline and The Cochrane Library were searched for articles published between January 1978 and January 2011 on the topic of antibiotic prophylaxis in gynaecologic procedures. Results were restricted to systematic reviews, randomized control trials/ controlled clinical trials, and observational studies. Searches were updated on a regular basis and incorporated in the guideline to June 2011. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

VALUES: The quality of evidence obtained was rated using the criteria described in the Report of the Canadian Task Force on Preventative Health Care (Table 1).

BENEFITS, HARMS, AND COSTS: Guideline implementation should result in a reduction of cost and related harm of administering antibiotics when not required and a reduction of infection and related morbidities when antibiotics have demonstrated a proven benefit.
