Who is your health care proxy or agent?
Most of us value our ability and freedom to make choices, especially about medical treatment. But what if you lose the capacity to make decisions or make your wishes known?
What if important decisions about your health and treatment were left to a physician who didn't know your values, beliefs, or preferences — or to a relative who is equally uninformed?
What if you wanted your best friend, who knows far more about you, to make those decisions on your behalf?
You can take control of this situation ahead of time through a living will or health care power of attorney (also called a health care proxy form) — documents known as advance care directives. Every adult should have one or both of these documents.
How advance care directives work
In a living will, you describe your goals for medical treatment in the event of serious and incapacitating illness or injury, your religious or spiritual beliefs, and any guidance you wish to give regarding your medical treatment in various circumstances. This document guides the people caring for you when you cannot express your wishes yourself. A health care power of attorney permits you to name a health care proxy, or agent — a person who can make those medical decisions on your behalf if necessary.
People sometimes worry that by signing one of these documents they give up control over their medical treatment. That is not true. As long as you're able to make and communicate your decisions, your word supersedes anything you've written or said to others.
An advance care directive goes into effect only when you're unconscious or too ill to make your wishes known — and once you recover, what you say takes precedence over any document.
