Abstract:

Introduction

Urinary tract infections are among the most common healthcare‑associated infections, with many cases linked to indwelling urinary catheters, known as catheter‑associated urinary tract infections (CAUTIs). Reducing bacterial colonisation around the urethral area before catheterisation has been shown to lower CAUTI risk, and emerging evidence suggests antiseptic use may further reduce infections. Clinicians commonly use either saline (0.9%) or chlorhexidine (0.1%) for meatal cleaning; however, practice varies considerably, and guidelines remain unclear. The lowering Catheter Associated urinary Tract infectIONs (CATION) trial aims to evaluate the efficacy and cost‑effectiveness of chlorhexidine (0.1%) compared with saline prior to catheter insertion for CAUTI prevention.

Methods

This world-first, multicentre, double-blind, parallel randomised controlled trial (RCT) will be conducted across three Australian hospitals (NSW and QLD) over a 6-8 month period. A Clinical Nurse Consultant (CNC) at each site will deliver the intervention five days per week, undertaking consent, meatal cleaning, catheter insertion, and follow-up for patients requiring an indwelling catheter. Ward staff will support recruitment by notifying the CNC when catheterisation is required. The primary outcome is the incidence of confirmed CAUTIs within seven days of catheter insertion. Secondary outcomes included confirmed catheter-associated asymptomatic bacteriuria (CA-ASB), time to first CAUTI, and the intervention's cost-effectiveness.

Results

The RCT will conclude in June 2026 with approximately 560 participants included. Results are expected in 2027.

Conclusions

The CATION trial will provide high-quality evidence to guide CAUTI prevention practices and inform future clinical guidelines, with the aim of improving patient outcomes.
