A prospective interventional study to examine the effect of a silver alloy and hydrogel-coated catheter on the incidence of catheter-associated urinary tract infection.

摘要: Introduction Catheter-associated urinary tract infection is a major hospital-acquired infection. This study aimed to analyse the effect of silver alloy and hydrogel-coated catheter on occurrence catheter-associated Methods was 1-year prospective conducted at single centre in Hong Kong. Adult patients with an indwelling for longer than 24 hours were recruited. The incidence conventional latex Foley without hydrogel compared that catheter. most recent definition based latest surveillance National Healthcare Safety Network managed by Centers Disease Control Prevention. Results A total 306 recruited similar ratio between males females. mean (standard deviation) age 81.1 (10.5) years. numbers catheter-days 4352 7474 silver-coated groups, respectively. incidences per 1000 6.4 9.4, respectively (P=0.095). There 31% reduction group. Escherichia coli commonly involved pathogen (36.7%) all cases. Subgroup analysis revealed protective more pronounced long-term users as well female respective 48% (P=0.027) 42% (P=0.108) catheterisation time person longest using (17.0 days) those (10.8 or both types (13.6 [P=0.01]. Conclusions Silver catheters appear be effective preventing definition. perhaps prominent patients.
