RESUMEN
BACKGROUND: Surgical site infection (SSI) following caesarean section is a problem for women and health services. Caesarean section is a high volume procedure and the estimated incidence of SSI may be as high as 9%. OBJECTIVES: The objective of this study was to identify a suite of perioperative strategies and surgical techniques that reduce the risk of SSI following caesarean section. SEARCH STRATEGY: Six electronic databases were searched to systematically review literature reviews, systematic reviews and meta-analyses published from 2006 to 2016. Search terms included: endometritis, SSI, caesarean section, meta-analysis, review, systematic. SELECTION CRITERIA: Studies were sought in which competing perioperative strategies and surgical techniques relevant for caesarean section were identified and quantifiable infection outcomes were reported. General infection control strategies were excluded. DATA COLLECTION AND ANALYSIS: Data on study characteristics and clinical effectiveness were extracted. Quality, including bias within individual studies, was examined using a modified A Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist. Recommendations for SSI risk-reducing strategies were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS: Of 466 records retrieved, 44 studies were selected for the evidence synthesis. Recommended strategies were: administer pre-incision antibiotic prophylaxis, prepare the vagina with iodine-povidone solution and spontaneous placenta removal. CONCLUSIONS: We recommend clinicians implement pre-incision antibiotic prophylaxis, vaginal preparation and spontaneous placenta removal as an infection control bundle for caesarean section. FUNDING: Queensland University of Technology. TWEETABLE ABSTRACT: Infection control for caesarean: pre-incision AB prophylaxis, vaginal prep, spontaneous placenta removal.
