A proxy stands in for you at the moment you can't speak, in the room where decisions get made fastest and with the least time to think. The research says even the people closest to you get your wishes wrong about one time in three. That should change how seriously you take naming one.
A proxy is only as good as the conversation behind the name.
A Healthcare Proxy Is Not a Power of Attorney
A healthcare proxy, sometimes called a medical power of attorney, speaks for you on medical decisions when you can't speak for yourself. A general or financial power of attorney is a different role entirely. It handles money and property and has nothing to do with medical care, though people conflate the two constantly.
Whatever it's called on paper, a proxy's job is the same. Communicate wishes you've already documented and discussed. Not invent an answer. Not decide based on what they would want in your position.
Pick the Calmest Person, Not the Next in Line
People default to whoever's next: the spouse, the oldest child. They never ask who can actually do the job under pressure, in a hospital hallway, with a doctor waiting for an answer and relatives possibly disagreeing.
The right proxy stays calm in that moment, asks the doctor hard questions instead of deferring, and holds to what you said even when another family member pushes back emotionally. That isn't always the person closest to you. Sometimes the person who loves you most is too devastated to advocate clearly for what you wanted.
Proxies Get It Right About Two-Thirds of the Time
A systematic review of surrogate decision making found that family members and appointed proxies correctly predict a patient's treatment preferences only about 68 percent of the time. Roughly one guess in three is wrong, even among people who know the patient well and believe they understand.
A form doesn't close that gap. The conversation does, repeated over time and stated in specific terms, not general feelings.
Tell Your Proxy Why
Don't hand them the checkbox result. Give them your full code reasoning. Tell them, in concrete terms, what makes your life worth living. Then tell them again, because people forget conversations they only had once, especially under the stress of acting on them years later when the moment finally arrives.
If you don't have those answers yet, these five questions will give you something to say.
