Catheter-Associated Urinary Tract Infections (CAUTIs) occur when bacteria enter the urinary tract through a urinary catheter, a tube used to drain urine. These infections are common in patients who require long-term catheterization, often in hospitals or nursing homes. Symptoms may include fever, chills, and pain during urination. Preventing CAUTIs involves proper catheter insertion and maintenance techniques, such as keeping the area clean and ensuring the catheter is only used when necessary. Healthcare providers follow guidelines to minimize infection risks, which can lead to complications if not addressed promptly.
