Surveillance for postoperative infections in outpatient gynecologic surgery.

Postoperative infection rates were determined for gynecologic outpatient surgical procedures performed in a traditional operating room environment and a separate, recently opened, surgicenter within the same hospital. Infections were self-reported by attending surgeons responding to computer-generated line listings of their recent surgical procedures. Responses were obtained on 97.9% (612/625) of women having surgery in the operating room and 99.5% (629/632) of women with surgicenter procedures. The overall infection rate for reported women was 0.9% (11/1,241). The difference between operating room and surgicenter rates was not statistically significant. Postoperative infections occurred in 2.5% (3/118) of diagnostic laparoscopies with tubal lavage and 1.4% (3/214) of voluntary abortions by dilatation and evacuation and curettage (D&E&C). The five other infections were scattered among the remaining 25 procedure categories. Ten of the 11 infections were limited to the "clean-contaminated" wounds. No serious or life-threatening infections were encountered. The computer-assisted surveillance system worked well and was easily incorporated into the existing infection surveillance system. The degree of ascertainment of postoperative wound infections is unknown due to reliance on physician self-reporting. However, no patients requiring readmission for infection went unreported by the attending surgeons.
