Yes, under Connecticut law, there are certain people who you cannot name as your health care representative:
Your attending physician or advanced practice nurse
An employee of a government agency that is financially responsible for your medical treatment
Anyone who works in a nursing home, hospital, or residential care facility where you are a patient, with exceptions for blood relatives.
Your health care representative cannot act as a witness to your advance directives. If you reside in a state-run health facility, you may need to ask friends or family members outside of the facility to witness your health care directive and living will and your health care representative designation.
