The Problem with Catheters
Just as in an open skin wound, a compromised bladder lining has a much higher incidence of infection.

Bladder 48 Hours after Catheterization
More examples of mucosal damage after catheterization.
The solution shouldn’t exacerbate the problem.
Not only is damage to the mucosal lining evident in just a short period of time following catheterization, but up to Day Seven, biofilm build-up on catheter surfaces over time can harbor bacteria; the risk of Infection increases 5% for every day a catheter is in place.
In recent years, some manufacturers have addressed the problem by introducing antimicrobial and silver-coated catheters designed to attack biofilm. The true effectiveness of coated closed systems is debated in the medical literature. Some studies indicate > 30% reduction in infection rates in the first 36 hours.1,2 Other review articles conclude little difference and no difference in applications over 72 hours.3,4
If biofilm were truly the root cause of CAUTIs, most clinicians would expect infection rate to improve 70-90 % in longer term applications, not merely the 30% in short term applications shown in most studies.
Although coated closed systems undoubtedly reduce bacteria reaching the bladder, current Foley materials and tip design themselves likely contribute significantly to CAUTI infections and mask true effectiveness of anti-biofilm coatings.
By causing the very damage to the bladder lining that can provide a breeding ground for any bacteria that manage to circumvent the coated system, these closed systems failed to address a major aspect of the problem. Further improvement needed to be made to compliment the advantages of the coated systems. Making its debut is a new catheter product that does just that.
This new catheter design, the Duette by Poiesis Medical, is the next logical improvement in urinary drainage management. Any hospital, healthcare facility, doctor, or home health care agency interested in improving outcomes and reducing costs should contact Poiesis Medical about this latest innovation in the evolution of the urinary catheter.
