Why are catheter related infections still so common?

Measuring the effectiveness of antimicrobial-coated catheters


“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.”

    I'm only a first year student nurse who has no practical experience but from reading this could it be that CAUTI's occur due to the irritation caused by the catheter tube itself rather than bacteria? Just a thought...

  • I have seen too many catheters on the ward touching the floor instead of being hoisted on a catheter stand, I try to correct this anytime I see such. Most times the wards do not have catheter stands and hang it over bedside rails. There is a need for the awareness of the effect of this poor practice on patient's well being.

    same with oxygen masks and nasal tubes lying in the bed or on the floor and recovered and put straight back on patient's face or nostrils by patient, visitors and sometimes even the staff.
