OBJECTIVE To investigate the current status and influencing factors of surgical site infection (SSI) in type I incision surgeries at 68 medical institutions in Tianjin, providing references for the prevention and control of SSI in type I incision surgeries.
METHODS A retrospective questionnaire survey was conducted on the SSI situation in type I incision surgeries at 29 secondary medical institutions and 39 tertiary medical institutions in Tianjin in 2024. Multivariate logistic regression analysis was used to analyze the influencing factors of the SSI rate in type I incision surgeries at medical institutions in Tianjin.
RESULTS This survey covered 68 medical institutions, with the SSI rate in type I incision surgeries ranging from 0% to 1.29%, averaging 0.15%. Among them, 45 (66.18%) medical institutions had an SSI rate in type I incision surgeries below the average, while 23 (33.82%) had a rate above the average. The results of multivariate logistic regression analysis indicated that comprehensive medical institutions (OR=28.073) and high prophylactic antibiotic usage rate before type I incision surgeries (OR=1.059) were risk factors for a higher-than-average SSI rate in type I incision surgeries at medical institutions (P＜0.05), while medical institutions with standard operating procedures for preoperative preparation (OR=0.024) and high hand hygiene compliance rate (OR=0.888) were protection factors (P＜0.05).
CONCLUSIONS Comprehensive prevention and control measures should be implemented based on the influencing factors of the infection rate to reduce the SSI rate in type I incision surgeries.
