An advance directive is a personal statement of how medical care
choices should be made and who should make them in the event a person is unable
to communicate, such as from having a severe injury or illness. A medical power
of attorney, which appoints a person (called a health care agent or proxy) to
make medical treatment decisions, and a living will are types of advance
directives.
Advance directives should be documented and comply with the
guidelines established within a person's state of residence. The provisions
within an advance directive, such as when to continue or abandon life-support
measures, also should be discussed with a health professional, family members,
and other potential decision-makers.
