What is catheter-associated urinary tract infection (CAUTI)?

Catheter-associated urinary tract infection (CAUTI) specifically refers to a urinary tract infection that develops in a patient who has an indwelling urinary catheter in place. The presence of the indwelling catheter creates a pathway for bacteria to enter the urinary tract, leading to infection. This definition is crucial for understanding the context and management of urinary tract infections within healthcare settings.

The focus on the indwelling catheter is important because it distinguishes CAUTI from other types of urinary tract infections that can occur independently of catheterization. CAUTI is a common complication in patients who require long-term catheterization and has implications for patient care, infection control, and quality of healthcare. Notably, CAUTI is also a key consideration in healthcare-associated infections and can influence hospital stay lengths, patient outcomes, and antibiotic stewardship.

Understanding CAUTI is vital for healthcare practitioners to implement appropriate prevention strategies, such as maintaining aseptic technique during catheter insertion and ensuring catheter use only when necessary.
