2016 WHO GLOBAL GUIDELINES FOR THE PREVENTION OF SURGICAL SITE INFECTION: A NEW STEP TO IMPROVE PATIENT'S SAFETY BEFORE, DURING AND AFTER SURGERY

Surgical site infection (SSI) are among the most preventable health-care-associated infections and are a substantial burden to health-care systems and service payers worldwide in terms of patient morbidity, mortality, and additional costs. SSI prevention is complex and requires the integration of a range of measures before, during and after surgery. No international guidelines are available and incosistencies in the interpretations of evidence and recommendations of national guidelines have been identified. Given the burden of SSI worldwide, the numerous gaps in evidence-based guidance, and the need for standardisation and a global approach, WHO decided to prioritise the development of evidence-based recommendations for thew prevention of SSI. The guidelines take into account the balance between benefits and harms, the evidence quality, costs and resource use implications, and patgients values andf preferences. on the basis of systematic literature reviews and expert consensus, we present 23 recommendations on preoperative, intraoperative and postoperative preventive measures. The WHO recommendations were developed with a global perspective and they take into account the balance between benefitgs and harms, the evidence quality level, cost and resource use implications, and patient values and preferences
