An Advance Health Care Directive is a set of documents consisting of a Power of Attorney for Health Care and a Living Will, that allows you to make decisions about future health care issues, by allowing you to give health care instructions, select a health care agent or do both. By using an Advance Directive, you can also make decisions about life-sustaining procedures in the event of persistent vegetative state, terminal condition, or end-stage conditions. You can also use the advance directive to make any other health care decisions.
