Medicated Foley Catheters Do Not Prevent Catheter-Associated Urinary Tract Infection: A Systematic Review of Randomized Controlled Trials
Abstract
Infections of the urinary tract are among some of the most common infections treated in clinical practice. Numerous risk factors play an intrinsic role in the development of such infections, namely: age, sexual intercourse, prolonged use of feminine hygiene products, instrumentation, pregnancy, sexually transmitted infections, obstructive uropathy such as prostatic enlargement or urethral strictures, compromised immunity, and constipation. A major cause of urinary tract infections (UTIs) in hospitalized patients is catheter-associated urinary tract infections (CAUTIs). This systematic review aims to identify the causative agents and risk factors and to determine whether nitrofurazone, silver alloy, or zinc oxide-impregnated or coated/medicated Foley catheters, or non-medicated (standard) Foley catheters, can reduce the incidence of CAUTIs. A systematic review was conducted on the following databases: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Trip medical database, and Google Scholar. A combination of keywords and Boolean operators was used ((((urinary tract infections) OR (urinary catheterization)) OR (prevention AND control)) ) AND (catheter-associated infections) for data extraction. All the randomized controlled clinical trials (RCTs) completed and available between January 1, 2005, and June 30, 2024, which focused on the prevention of CAUTIs, were screened thoroughly and were included in this systematic review. The Cochrane risk-of-bias tool for…
