I just read your posting and would be happy to reply. In our home program we teach the same catheter care that the patients receive in-center. I have the patient and family member/care giver mask, glove and gown. They are taught strict aseptic technique when preforming any care on the catheter including changing gloves and washing hands. Infection rates in general appear less in the home setting due to the limited care givers and personal care, attention and devotion they have.
We clean the site with betadine, unless allergic, apply ointment, and dress with a breathable dressing. They are instructed to remove the dressing for showers, etc. and redress for security/comfort.
