A Cohort Study of Traffic in Theatre as a Risk for Surgical Site Infection at Three Tertiary Hospitals in the Copperbelt Province, Zambia

Le résumé fourni par la source

Introduction: The rate of operating-theatre room nosocomial infections is estimated at 10% of surgical site infections (SSI) in postoperative wounds. Earlier studies have suggested that restricting traffic by head count and reducing the number of door-openings of the operating room could reduce the development of SSI. This study was done to determine whether traffic in theatre by head count or door-openings was a risk for the development of SSI. Methods: This was a prospective observational cohort study conducted at 3 tertiary hospitals in the Copperbelt Province of Zambia. Results: A total of 1122 participants were included. Of the total study population, 468 were females and 654 were males. A total of 218 participants, representing 19.4%, developed surgical site infection proven by pus results. This study showed no association between the number of people by head count in the operating theatre and the development of SSIs. All p-values for head counts were not significant. However, the number of door-openings was significantly associated with the risk for development of SSI. Conclusion: The prevalence of SSI at the 3 tertiary institutions was 19.4%. An increased number of door-openings was significantly associated with SSI.
