Abstract

Background: Surgical Site Infection (SSI) is one of the most common healthcare-associated infections, increasing healthcare cost, hospital stay, morbidity burden as well as the rate of mortality. Objectives: The aim of this study was to decribe the incidence of SSI and risk factors at University Medical Center, Ho Chi Minh City. Methods: A prospective cross-sectional study was conducted involving 859 operated patients at University Medical Center, Ho Chi Minh City during 05/2020 - 12/2020. Background information including having diabetes, ASA score, antibiotic prophylaxis, the type of the surgical procedure, preoperation bathing, operative duration and surgical site infection were collected. Results: The overall SSI rate was 2,2%, ranging from 1,3% to 20,0%. Among which, the SSI rates classified by procedure type were: 20% in small bowel surgery, 5,5% in cardiac surgery, 4,5% in gastrectomy, 4,2% in cholecystectomy and hepatobiliopancreatic surgery, 4,1% in craniotomy. The mean time of the duration between surgery starting-point and the onset of infection was 11,9 ± 7,8 days, while the longest duration was in cardiovascular surgery with over 20 days. The rate of SSI in patients with diabetes was related with a 6,5-fold increase (95% CI: 2,8-14,7); ASA score ≥ 3 with 2,6-fold increase (95% CI: 1,8-3,6); operative time prolonging more than 1 hour with 1,3-fold increase (95% CI: 1,1-1,6); and every one more surgeon added to the operating team lead to a 1,9-fold increased in SSI rates (95% CI: 1,3-2,9). Conclusions: The overall incidence of SSI in our study was 2,2%. The mean time from surgery starting-point until the onset of infection is 11,9 ± 7,8 days. The significant risk factors were having diabetes, high ASA score, increased operative duration, increased length of hospital stay, the type of intervention and the increased number of surgeons.
