What is a common risk factor for healthcare-associated urinary tract infections (UTIs)?

The insertion of urinary catheters is a common risk factor for healthcare-associated urinary tract infections (UTIs) because catheters provide a direct pathway for bacteria to enter the bladder, which increases the likelihood of infection. The presence of a foreign object, like a catheter, disrupts the normal anatomical barriers that typically protect the urinary tract from pathogens. This situation is compounded by the fact that patients with catheters may have impaired immune responses or other underlying health issues, making them more susceptible to infections.

While inadequate patient mobility and low levels of hydration can contribute to UTIs, they are not as directly linked to healthcare-associated infections as catheter use. Frequent handwashing by healthcare workers is an important infection control measure that actually helps reduce the risk of UTIs and other healthcare-associated infections. Therefore, the insertion of urinary catheters stands out as a significant risk factor for the development of UTIs in healthcare settings.
