A web-based surveillance of surgical site infection (SSI) in Korean Nosocomial Infections Surveillance (KONIS) System started from 2007. Up until 2009, SSI surveillance of KONIS was a laborious and time consuming task due to massive amount of data collected for risk factor analysis. It was a main obstacle to expand the number of participating hospitals and target operative procedures. Therefore, the SSI module of KONIS underwent a drastic change in 2010.
We have largely reduced categories to be investigated, and the duration of participation has been shortened for 3 months, rather than 6 months in the surgery with implantation. The number of target operative procedure to be on observation has been 15. The surveillance for surgery with implant insertion was changed from 1 year to 120 days between July 2012 and June 2013. Then, surveillance period for implant surgery was reduced from 180 days to 90 days beginning in July, 2013. The results of new SSIsurveillance were as follows:
1. The number of participating institutions has been increased from 43 in 2012 to 60 hospitals in 2012, and up to 62 hospitals in 2013.
2. We analysed the complete collected surveillance data between October 2012 and September 2013. With regard to surgical procedures, SSI rates were 3.12% in colon surgery which was most common, 3.42% in rectal surgery, 2.92% in craniotomy, 2.38 % in gastrectomy, 0.88% in abdominal hysterectomy, 0.74% in gallbladder surgery, 0.04% in cesarean section, 0.74% in laminectomy and 0.18% in vaginal hysterectomy. The interim results of seven implant-related surgery, which was completely analyzed from October of 2011 to April of 2013, SSI rates were 5.22% in coronary artery bypass graft with donor graft, 3.60% in cardiac surgery, 2.76% in CABG with chest incision, 2.72% in ventricular shunt operation, 1.63% in spinal fusion, 1.52% in hip prosthesis, and 1.18% in knee prosthesis.
