The persistent breach between evidence and practice in the prevention of surgical site infection: Qualitative study

Background: Despite the dissemination of guidelines for surgical site infection (SSI) prevention, a gap between the theoretical measures and their compliance persists. Accurate estimates of the implementation of preventative measures is crucial before planning dissemination strategies. Methods: A web-based survey was distributed to members of 11 Associations of operative nurses and surgeons. Questions aimed to determine their awareness of evidence, personal beliefs and actual use of the main preventative measures. Results: Of 1105 responders, 50.5% receive no feed-back of their SSI rate. Responders show a moderate rate of awareness of the recommendations about not removing hair, hair clipping, skin antisepsis with alcoholic solutions, and normothermia. Antibiotic prophylaxis is given for more than 24 h by 18.8% of respondents. Screening for S. aureus is performed by 27.6%. Hair removal by shaving is used by 16.6% of responders. The most common antiseptic solutions are alcoholic chlorhexidine (57.2%) and aqueous povidone (23.3%). 62.8% of surgeons allow the solution to air dry before applying surgical drapes. Adhesive drapes in the surgical field are used routinely in 33.4% of cases. Perioperative normothermia, glucose control and hyperoxia are used in 84.3%, 65.9% and 23.3% of cases. Antimicrobial sutures and negative pressure therapy are used by 20.2% and 43.5% of teams, respectively. Prior to closing the incision, 83.9% replace surgical instruments always or selectively. Wound irrigation before closing is used in 78.1% of cases, mostly with saline. Check-lists, standardized orders, surveillance, feed-back and educational programs were rated most highly by respondents as a means to improve compliance with preventative guidelines, but few of these strategies were in place at their institutions. Conclusion: Gaps in the translation of evidence into practice remain in the prevention of SSI among different surgical specialities. Several areas for improvement have been identified, as some core prevention measures are not in common use.
