Why is catheter-associated urinary tract infection still a challenge?

  • Comments (2)

Key points

  • Patients with urinary catheters are at high risk of infection.
  • Catheters reduce the body’s natural ability to cleanse the urinary tract of micro organisms.
  • Bacteria can be free floating or can colonise into biofilms that attach to the catheter surface and may cause catheter blockage.
  • Biofilms can develop a resistance to antibiotics.
  • Silver alloy urinary catheters can reduce biofilm formation and colonisation by releasing silver ions into the urinary tract.

Let’s discuss

  • Why does catheter-associated urinary tract infection (CAUTI) remain a persistent challenge in healthcare?
  • What strategies have you found to be effective in reducing CAUTI?
  • Looking at the evidence in this article, do you think silver alloy catheters should be used routinely in clinical practice?

    Having edited more articles on CAUTI than I care to remember, it seems that healthcare providers are often far more keen to catheterise patients than to remove catheters. Is this because there is a perception that catheters save time or the lack of a system to ensure patients' need to remain catheterised is regularly checked?

    Silver lined Intra Ventricular Drains/catheters have been proved to reduce infections, so why not in Urinary Catheters also?
