Surgical Site Infection after Orthopedic Surgery Performed in Dong Guan Hospital of Traditional Chinese Medicine: A Descriptive Study of the Burden of Surgical Site Infection and its Risk factors with A Focus on Antimicrobial Prophylaxis and Traditional Chinese Medicine in Spinal Surgery

Background: Surgical site infection (SSI) is a serious complication after orthopedic surgery, and it is associated with high morbidity rates, high healthcare costs and in some cases poor patients outcomes. Aims: The purpose of this study was to identify the burden of SSI among orthopedic surgery and its associated risk factors of SSI among the people underwent spinal surgery in a selected hospital in China. Methods: From June 26 to November 30 in 2014, we performed a prospective surveillance study in the patients who underwent orthopedic surgery in a selected Chinese hospital. SSI was diagnosed based on the definition established by the Centers for Disease Control and Prevention (CDC) and was identified by bedside surveillance and post-discharge checkup. Detailed pre-, intra-, post-operative patient characteristics were prospectively recorded using a standardized data collection format. Results: A total of 287 orthopedic surgery cases, among them 192 cases of spinal surgery, were included, of which 8 cases developed surgical site infection. Wound contamination class, wound drains and blood transfusion were surgery-related risk factors for orthopedic spinal surgery during the hospital stay after bivariate analysis. Intravenous AMP was given in 176 of 287 (61.3%) after orthopedic surgery. The average duration of AMP administration was 2.2 days (range 1-9 days). Conclusion: In conclusion, we identified an incidence proportion of SSI after orthopedic surgery of 2.8%. The orthopedic SSI risk factors (wound contamination class, wound drains and blood transfusion) identified in present study may use to be reducing the incidence of SSI in the future.
