good question. Before 8/30/09 the registry attempted to keep track of caregiver-patient relationships, and they would attempt to send out notices regarding patient changes. That proved impossible, so the registry dropped it. THEY NO LONGER TRACK this info, so it's unclear why we even have to send in a change of caregiver form (notorized or not). Currently the only legal way for a patient to remove you as a caregiver is for said patient to write you a letter, call you on the phone, or verbally tell you in person that they no longer require your caregiver service. If your patients haven't done that, then you can legitamately consider them 'yours' still.
