Surgical-site infection surveillance in general surgery: a critical issue.

This prospective study assessed the Surgical Site Infection (SSI) rates in General Surgery and the microorganisms isolated. From January 2000 to October 2000, 898 patients were enrolled and electively operated in a General Surgery Clinic in Athens, Greece. Pre-coded questionnaires were used. The diagnosis and surveillance of SSIs was made by the surgeon-investigator who interviewed the patients. Patients were monitored during hospitalization and post-discharge for 30 days. Overall, 402 patients underwent a clean and 496 patients underwent a clean-contaminated operation. A total of 17 SSIs (4.2%) were observed in clean and 64 SSIs (12.9%) in clean-contaminated operations. Microorganisms were isolated in 36 of 65 (55%) of cases that microbiological evaluation was performed. Staphylococcus aureus was the commonest microorganism isolated, followed by Escherichia coli and Pseudomonas aeruginosa. SSI rates were higher than expected and most SSIs, 43 of 81 (53.1%), were diagnosed post-operatively. Post-discharge surveillance of SSIs remains a critical issue. Health care professionals, especially surgeons, should participate in surveillance networks and be aware of the results so to take appropriate action.
