“Catheter-associated urinary tract infections (CAUTI) are a major cause of morbidity in hospitals worldwide. Urethral catheters coated with antimicrobial substances such as silver alloy and nitrofurazone were introduced as a strategy to reduce CAUTI. A previous Cochrane review reported that antimicrobial-coated or impregnated catheters may reduce the number of asymptomaticbacteriuria present, but it was uncertain whether they reduced CAUTI.
“The Catheter Trial compared these catheters with standard catheters for short-term use in NHS hospitals, in terms of CAUTI reduction. The results showed that silver alloy-coated catheters did not reduce symptomatic CAUTI compared with standard catheters, while nitrofurazone-impregnated catheters had borderline clinical benefit in reducing symptomatic CAUTI. The findings do not support the routine use of antimicrobial-coated or impregnated catheters for patients who need short-term catheters in hospital. Health professionals should instead focus on simple preventative strategies and reducing the need for catheterisation.”
- Do antimicrobial-coated catheters provide misplaced reassurance?
- Why are catheter related infections still so common?
