300병상 이하 병원에서의 카테터 연관 요로감염의 발생률

Abstract

Background: Catheter-associated urinary tract infection is a major infection in healthcare facilities. We investigated the urinary catheter utilization ratio and incidence of catheter-associated urinary tract infections in small-sized hospitals with ≤300 beds. Methods: We recruited hospitals via a web-based survey from July 2016 to September 2016. Infection control practitioners provided data about catheter-associated urinary tract infections on the website according to the prescribed form. The urinary catheter utilization ratio was calculated by dividing the number of device-days by the number of patient-days. The incidence of catheter-associated urinary tract infections per 1,000 device-days was calculated by dividing the number of urinary tract infections in patients with indwelling urinary catheter by the number of indwelling device-days and multiplying by 1000. The urinary catheter utilization ratio and incidence of catheter-associated urinary tract infections were compared between hospitals with ＞200 beds and ≤200 beds.Results: Twenty-seven hospitals were included. The average urinary catheter utilization ratio was 0.4 (0.47 in hospitals with ＞200 beds and 0.38 in hospitals with ≤200 beds; P=0.1). The incidence of catheter-associated urinary tract infections was 1.59 per 1,000 device-days. There was no significant difference in the incidence of infections according to the number of beds (1.53 in hospitals with ＞200 beds vs 1.9 in hospitals with ≤200 beds, P=0.421). Conclusion: The incidence of catheter-associated urinary tract infections in small-sized hospitals was considerably high. Efforts must be made to attenuate the infection rates through proper infection control and monitoring.
