An advance directive is a document giving direction to health care providers about treatment choices. Advance directives convey decisions, in advance, about end-of-life care. There are two types of advance directives, a living will and a health care power of attorney.
Health Care Proxy (Durable Health Care Power of Attorney)
A living will documents wishes regarding end-of-life medical treatments but does not name an agent. Living wills tell how a person feels about care intended to sustain life. Though many issues are addressed, you can accept or refuse medical care.
A health care power of attorney or “health care proxy” appoints a person as a proxy (health care agent or surrogate decision maker), who is authorized to direct medical decisions when the principal is unable to do so.
