How can catheters contribute to healthcare associated infections?

Catheters can contribute to healthcare associated infections primarily when they are not managed properly, which can lead to specific types of infections such as urinary tract infections (UTIs) and bloodstream infections. The introduction of a catheter into the body creates a pathway that can allow bacteria to enter the urinary tract or bloodstream.

If the catheter is not placed or maintained in a sterile manner, or if proper hygiene practices are not followed during insertion or care, pathogens can easily multiply and cause infections. For example, indwelling catheters, which remain in the bladder for extended periods, can become colonized with bacteria over time, leading to increased risk of UTIs. Similarly, central venous catheters, which are inserted into large veins, can pose a risk for bloodstream infections if they are not properly managed.

This understanding highlights the importance of strict adherence to infection control protocols when using catheters, including proper insertion techniques, regular monitoring, and timely removal when they are no longer necessary. Proper education and training in catheter care are essential to preventing these HAIs.
