📚 Catheter-Associated UTI Prevention — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Catheter-associated urinary tract infection (CAUTI) is one of the most common and most preventable healthcare-associated infections. The single most effective prevention is avoiding unnecessary catheters and removing them as early as possible. Maintaining a closed, dependent, unobstructed drainage system prevents organisms from ascending into the bladder.
🔑
Key points
Understand these first
Insert indwelling catheters only for valid indications and remove them at the earliest opportunity.
Early removal is the most effective measure to prevent CAUTI.
Maintain a sterile, closed drainage system; breaking the closed system raises infection risk.
Keep the collection bag below the level of the bladder and off the floor to prevent backflow.
Secure the catheter to prevent traction and keep tubing free of kinks and dependent loops.
Perform daily perineal and meatal hygiene with soap and water, not antiseptics.
✅
Nursing priorities
What to do, in order
Advocate daily for catheter necessity and prompt removal when no longer indicated.
Keep the drainage bag below bladder level and the tubing unobstructed.
Maintain the closed system; empty the bag through the drain port using a clean technique.
Provide daily perineal hygiene and secure the catheter to prevent tension.
Perform hand hygiene before and after handling the catheter or drainage system.
🚩
Red flags — report now
Escalate immediately
Never raise the drainage bag above the bladder or rest it on the floor.
Do not disconnect or open the closed drainage system unless absolutely necessary.
Report new fever, cloudy or foul-smelling urine, or suprapubic pain as possible CAUTI.
🧪
Labs & values
Numbers to know
Urinalysis: positive leukocyte esterase and nitrites suggest infection
Urine culture: 10^5 colony-forming units/mL indicates significant bacteriuria; WBCs in urine normally fewer than 5/hpf
🗣️
Patient teaching
What patients must know
Keep the drainage bag below the waist and bladder at all times, including when walking.
Maintain adequate fluid intake unless restricted.
Report fever, burning, or cloudy urine promptly.
