Effective interventions to prevent catheter-associated urinary tract infections: a systematic review.

Catheter-associated urinary tract infections (CAUTIs) are a prevalent and preventable healthcare-associated infection that significantly impacts healthcare systems, contributing to increased patient morbidity, length of stay, and costs. This systematic review aims to evaluate the effectiveness of various interventions in reducing CAUTI incidence in healthcare settings. Following the PRISMA guidelines, we conducted a thorough literature search across multiple databases-Web of Science, Scopus, PubMed, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Google Scholar-up to August 8, 2024. Eligible studies included randomized controlled trials, case-control studies, and experimental designs that met inclusion criteria, namely CAUTIs prevention among hospitalized adult patients. After screening 9,476 titles and abstracts, we reviewed 163 texts in full. Of these, 12 studies were included in this review. Results showed that antiseptic solutions like chlorhexidine, specialized catheters (e.g., BIP Foley and silver alloy-coated types) and educational sessions all significantly reduced CAUTI rates, with some interventions achieving reductions as high as 94%. Reminder systems promoting timely catheter removal and amikacin bladder washing also showed notable effectiveness. Adverse effects were minimal. This review underscores the importance of evidence-based CAUTI prevention strategies and the need for consistent implementation across healthcare facilities. Enhanced catheter maintenance practices and judicious catheter use can significantly reduce CAUTI rates, thereby improving patient outcomes and reducing healthcare-associated costs. Future research should continue exploring diverse, context-specific interventions to address barriers to CAUTI prevention.
