What are the nursing interventions to prevent catheter-associated urinary tract infections?

Catheter-associated urinary tract infections, or CAUTIs, are prevented by using indwelling catheters only when medically necessary and removing them as soon as possible. Insertion requires strict sterile technique. Maintain a closed drainage system and never disconnect the tubing. Keep the drainage bag below the level of the bladder at all times but off the floor. Perform perineal care daily. Secure the catheter to prevent traction and urethral trauma. Do not routinely irrigate the catheter. Empty the drainage bag regularly using a separate collection container for each patient.
