Room: Hall C
Background: A surgical site infection (SSI) develops in 2% to 5% of patients undergoing operation. We report SSI surveillance at Nantes University Hospital, France, in cardiac operation between 2002 and 2006, and demonstrate lower SSI rates accomplished with use of multiple intervention strategies. Methods: Infection documentation used CDC criteria. The major criteria used for mediastinitis definition at our institution were purulent discharge from mediastinal area or organisms cultured from mediastinal tissue or fluid obtained during a surgical operation or needle aspiration. Strategies used to lower SSI rates included active surveillance, reporting of SSI rate to surgeons, use of the French national guidelines for prevention of SSI, use of antibacterial suture, and patient skin preparation observations. Results: The endocarditis- and mediastinitis (after coronary artery bypass graft)-related SSI rates varied between 0.3% and 0.8%, and 0.9% to 1.1%, respectively between 2002 and 2006. The superficial SSI rate for 100 cardiac procedures decreased from 2.7% to 1.2% from 2004 to 2006. More than 95% of the French national guidelines criteria were respected (preoperative antiseptic showering, preoperative hair removal, patient skin preparation in the operating room) when performing assessment of professional practices. Conclusions: This study suggests that active surveillance, timely reporting of SSI rates to surgeons, and assessment of professional practices are associated with fewer infections at our institution.
