A systematic review and meta-analysis of antibiotic prophylaxis in skin graft surgery: A protocol.

Introduction: There is little evidence-based guidance on the use of prophylactic antibiotics in skin surgery; whilst antibiotics may protect against surgical site infections (SSI), they have associated side effects, increase the risk of adverse events, and can propagate antibiotic resistance. We present a protocol for a systematic review to establish whether the benefit of prophylactic antibiotics overrides the risk, for patients undergoing autograft surgery.

Methods: The systematic review will be registered a priori on researchregistry.com and will be conducted in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). A search strategy will be devised to investigate 'skin graft surgery and use of antibiotics'. The following electronic databases will be searched, 1979-2018: PubMed, MEDLINE®, EMBASE, SCOPUS, CINAHL, PsychINFO, SciELO, The Cochrane Library, including the Cochrane Central Register of Controlled Trials (CENTRAL), Database of Abstracts of Reviews of Effect (DARE), the Cochrane Methodology Register, Health Technology Assessment Database, the NHS Economic Evaluation Databases and Cochrane Groups, ClinicalTrials.gov, Current Controlled Trials Database, the World Health Organisation (WHO) International Clinical Trials Registry Platform, UpToDate.com, NHS Evidence and the York Centre for Reviews and Dissemination. Grey literature will be searched. All comparative study designs reporting on the use of antibiotics in skin graft surgery will be considered for inclusion, namely randomized controlled trials (RCTs). Two trained independent teams will screen all titles and abstracts, followed by relevant full texts, for eligibility. Data will be extracted under standardized extraction fields into a preformatted database. Note will be made of the indication for skin graft surgery (traumatic, congenital, malignant, benign), the graft site (head & neck, trunk, upper extremities, lower extremities), type of skin graft (split thickness, full-thickness). The primary outcome will be occurrence of SSI at the donor and/or recipient sites. Secondary outcomes, if reported, will include: length of hospital stay, revision surgery required, cost of medical care, time to wound healing and cosmetic outcome.

Ethics And Dissemination: The systematic review will be published in a peer-reviewed journal and presented at national and international meetings within fields of plastic, reconstructive, and aesthetic surgery. The work will be disseminated electronically and in print. Brief reports of the review and findings will be disseminated to interested parties through email and direct communication. The review aims to guide healthcare practice and policy.
