Advance directive
A document recording your medical wishes, and naming who should speak for you if you cannot.
What it means
Advance directive is an umbrella term. It usually covers a living will, which records what treatment you would want, and a healthcare power of attorney or proxy, which names a person to decide for you.
Many states combine both into a single form.
Why it matters
Without one, decisions fall to whoever the state's rules designate, which may not be the person you would choose — and disagreement between family members has no tie-breaker.
A directive that nobody can find does nothing, so where it is kept matters as much as what it says.
When you are likely to meet it
- When a parent is admitted to hospital.
- When a doctor asks whether there is a healthcare proxy.
- When planning ahead, alongside a will and a financial power of attorney.
The documents that speak for you about medical care
Four documents that are constantly confused, doing four different jobs.
| What is being compared | Living will | Health care proxy | POLST | DNR |
|---|---|---|---|---|
| What it does | Says what treatment you want | Names who decides | Records medical orders for a seriously ill patient | Orders that CPR not be attempted |
| Signed by | You | You | You and a clinician | A clinician |
| Takes effect | When you cannot decide | When you cannot decide | Immediately, as an order | Immediately, as an order |
| Who acts on it | Clinicians, interpreting it | Your named agent | Anyone treating you, including paramedics | Anyone treating you |
| Suits | Any adult | Any adult | Serious illness or frailty | A specific decision about resuscitation |
| Travels between settings | Not reliably | Yes, with the document | Designed to | Only with the right out-of-hospital form |
A wish is not an order. The first two say what you want; the second two instruct the people in the room.
How this varies by state
Names, forms and witnessing requirements differ by state, and not every state honors another state's form automatically.
