Prevalence of Surgical Site Infection after Orthopedic Surgery and Some Related Factors at the Selected Hospitals of Isfahan University of Medical Sciences

Introduction: Among wound infections of surgeries, those related to orthopedic surgeries are important and prevalent. The implantable instruments have been used in these surgeries that increase the risk of infection. The current study aimed to determine the incidence of wound infection in orthopedic surgeries and some of its effective factors in selected hospitals of Isfahan University of Medical Sciences. Methods and Materials: This is an analytical cross-sectional study. Sampling technique has been performed among 110 patients underwent orthopedic surgery in 2016 and 2017. Data have been collected through direct observation, preparation of microbiological culture and checklist. The relationship between the incidence of infection and some of the patient’s demographic information, the name and type of surgery, the use or non-use of the drainage system and the type of drainage system have been investigated in the present study. Wound infection has been determined based on apparent features and microbial culture. Data were analyzed through SPSS software version 20. Results: 18.2% of the participants were infected among 110 of them who were underwent orthopedic surgery. The highest rate of infection was related to foot surgery in various types of Tibia and Fibula fractures. All the infections are reported in men. The incidence of infection was higher among people whose ages were under 35 years. Moreover, emergency procedures had a higher risk of infection. In the present study, there was no significant relationship between the uses of various types of drainage systems with the development of surgical wound infections. Discussion and Conclusion: Reducing the incidence of orthopedic infection can be achieved by paying more attention to fractures that occur in the legs and open bones. Furthermore, according to the results of our study, the use of surgical drainage is not effective on reducing the infection rate. It is recommended that orthopedic surgeries team should follow health protocols to control and reduce infections.
