The Korean Surgical Site Infection Surveillance System Report, 2009 / 병원감염관리

ABSTRACT

BACKGROUND: A nationwide prospective multicenter study was performed in Korea to determine the incidence and risk factors for surgical site infections (SSI) after craniotomies (CRAN), ventricular shunt operations (VS), gastric operations (GAST), colon operations (COLO), rectal operations (RECT), hip joint replacements (HJR), and knee joint replacements (KJR). METHODS: We collected data regarding demographics, clinical and operative risk factors for SSI, and antibiotics administered to the patients who underwent CRAN in 18 hospitals, VS in 19 hospitals, GAST in 19 hospitals, COLO in 19 hospitals, RECT in 19 hospitals, HJR in 24 hospitals, and KJR in 23 hospitals between January and December 2009. All the data were collected using a real-time web-based reporting system. RESULTS: The SSI rate of CRAN, VS, GAST, COLO, RECT, HJR, and KJR was 3.68 (22/1,169), 5.96 (14/235), 4.25 (75/1,763), 3.37 (22/653), 5.83 (27/463), 1.93 (23/1,190), and 2.63 (30/1,139), respectively, per 100 operations. The only significant risk factor for SSI after CRAN was postoperative cerebrospinal fluid leakage. The independent risk factors for SSI after GAST were multiple procedure, reoperation, infection of other sites, and transfusion. In HJR, the duration of preoperative hospital stay and operation time were longer, and the need for general anesthesia, transfusion, and steroid use and the incidence of contaminated/dirty wound, obesity, and infection of other sites were significantly increased in the infected group. In KJR, the duration of preoperative hospital stay was longer and the need for reoperation was significantly higher in the infected group, and in addition, the incidence of SSI was higher among males. CONCLUSION: The maintenance of surveillance on SSI is very important because surveillance provides valuable information to the surgeon and infection control personnel, which in turn helps decrease the incidence of SSI.
