A patient`s prescription is a written statement about the health care and medical desires of a person who does not, however, appoint any other person to make health care decisions. Depending on the jurisdiction, a health power with a previous health directive may or may not appear in a single physical document. For example, the California legislature has adopted a standard mandate for health care and a prevention directive form that meets all of that state`s legal requirements for formulation for a precautionary mandate and directive in a single document.  Compare this to New York State, which has passed a health care representation law, which requires the development of a separate document in which one of them is appointed responsible for health.  In Australia, anyone who has power can give power.
