Purpose: Surgical Site Infection(SSI) is the third most common cause of nosocomial infection, so that it results in serious socioeconomic impact such as extra hospitalization, mortality and health care cost. The aim of this study was to analyses the SSI that based on the degree of wound contamination and patient risk index after general surgery and to generate a reference data for the effective management and reducing SSI.
Method: From July, 1999 to June, 2000, 1080 cases which presented with surgical site infection after general surgery at S hospital in chunchon city were included in this study. The data were collected by review of the medical records retrospectively. The collected data, in accordance with the test purpose, is analyzed by SPSS/PC+ program, using real numbers, percentage, X2 test, Pearson’s correlation and stepwise logistic regression
Result: The overall wound infection rate was 4.7%(51 cases out of 1,080). The infection rate of clean wounds was 1.4%. Surgical site infection rate for patient risk index scores of 0, 1, 2 and 3 was 1.9%, 8.0%, 13.1% and 20.0%, respectively and increased significantly according to patient risk index(p=.000). Sixteen of the fifty one(31.4%) surgical site infections were found during an outpatient visit after discharge. Multivariate analysis, identified two independent variables : duration of postoperation stay(p=.000), age(p=.037). The most frequent isolated organisms were Pseudomonas aeruginosa(21%) and Staphylococcus aureus(21%). Also Staphylococcus aureus were all MRSA(Methicillin Resistant S. aureus).
Conclusion: In this study, SSI was analysed according to the degree of wound contamination and patient risk index after general surgery. The data that obtained from this study is expected that it would be available for surveillance and control of SSI.
