Another important directive is a legal document called the Health Care Power of Attorney (HCPOA) which designates a person to make medical decisions in the event the patient is no longer able to express their own preferences - due to illness or unconsciousness. This legal document generally requires notarized signatures of the patient and one of more witnesses to the patient's signature. Unlike the physician orders (DNR, MOST, POLST) the HCPOA will generally include a listing of various patient preferences for receiving or declining medical treatment. In some jurisdictions - the HCPOA may not carry the same weight with emergency responders (EMTs) because EMTs may not know what form is required for the HCPOA document to be legally binding and the HCPOA may be a multipage document using legal language not understood by the EMT.
