An identification wristlet may be employed for any resident upon a physician's order, which shall document the need for the identification wristlet in the resident's clinical record. A facility may require a resident residing in an Alzheimer's disease unit with a history of wandering to wear an identification wristlet, unless the resident's guardian or power of attorney directs that the wristlet be removed. All identification wristlets shall include, at a minimum, the resident's name and the name, telephone number, and address of the facility issuing the identification wristlet.
