Final answer:
Regular assessment of catheter need is an evidence-based practice to prevent CAUTI, along with aseptic technique, proper positioning of the drainage bag, and daily cleaning of the insertion site.
Step-by-step explanation:
Based on the National Patient Safety Goals, an evidence-based practice or guideline to prevent indwelling catheter associated urinary tract infections (CAUTI) is the regular assessment of catheter need. Regularly assessing the need for a catheter can help prevent unnecessary catheterization and reduce the risk of infection. Other practices that can help prevent CAUTI include the use of aseptic technique during insertion and maintenance of the catheter, keeping the drainage bag below the level of the bladder, and daily cleaning of the catheter insertion site.
