The infection you prevent by planning to remove

Catheter-associated urinary tract infections are among the most common healthcare-associated infections — and largely preventable. The single biggest driver of risk is how long the catheter stays in: every day adds risk. So the strongest prevention is trying alternatives first (bladder scanner, intermittent/straight or external catheters, scheduled toileting), avoiding catheters that aren't truly needed, using the smallest appropriate catheter, and removing them promptly — ideally through a nurse-driven removal protocol.

Think of an open door to the bladder. A catheter props open a normally protected space. The longer it stays open, the more chances bacteria have to walk in.

While one is in place

  • Keep the drainage bag below bladder level and off the floor.
  • Maintain a closed system and secure the tubing.
  • Provide routine peri and catheter care with hand hygiene — clean the meatus with a per-policy antiseptic or sterile water/saline, never alcohol.
Recognize a CAUTI: fever, cloudy or foul-smelling urine, suprapubic or flank pain, and new confusion (especially in older adults). Report it.
📋 Reference — CDC appropriate indications for an indwelling urinary catheter (HICPAC). Place one only when there's a real reason, such as:
• Acute urinary retention or bladder-outlet obstruction.
• Accurate output measurement in a critically ill patient who needs it (e.g., hourly monitoring) — being in the ICU alone is NOT a reason.
• Selected perioperative needs (certain surgeries or expected long duration).
• To help heal an open sacral or perineal wound in an incontinent patient.
• Prolonged immobilization (e.g., unstable spine or pelvis), or end-of-life comfort.
If none of these apply, use an alternative (bladder scanner, intermittent/straight catheter, external catheter, scheduled toileting) — and remove any catheter as soon as its indication ends.

The most powerful habit

Ask every single day: "Does this catheter still need to be in?" If there's no clear indication, advocate to remove it.
