A POLST is a medical order signed by a physician, and paramedics follow it on the spot. An advance health care directive is a legal document that names your agent and states your wishes, and someone has to read and interpret it.
The difference matters most in the first ten minutes of an emergency, which is exactly when nobody is reading a binder.
Who a POLST is for
It is intended for people who are seriously ill or frail, generally those whose physician would not be surprised if they died within the next year. It is not a document for a healthy 55-year-old, and completing one prematurely can lead to treatment decisions you did not intend.
This is not our document to prepare. A POLST comes from your physician, is signed by your physician, and is a clinical conversation. We tell clients about it because plenty of people have never heard of it and their parent needed one two years ago.
How the two documents compare
| Advance directive | POLST | |
|---|---|---|
| What it is | Legal document | Physician's medical order |
| Who signs | You, plus witnesses or a notary | You and your physician |
| Who it is for | Every adult | Seriously ill or frail patients |
| Names an agent | Yes | No |
| Followed by paramedics | Not directly | Yes, immediately |
| Where it lives | With your agent and your doctor | On the refrigerator, bright pink |
It is pink for a reason
The California POLST is printed on bright pink paper and is meant to be visible where responders will find it, usually the refrigerator door or above the bed. A POLST filed neatly in a drawer does not do its job.
What it covers
- Whether to attempt CPR if the person is found without a pulse.
- The level of medical intervention wanted, from comfort-focused care to full treatment.
- Whether to use artificially administered nutrition, and for how long.
Those are choices with real consequences and they belong in a conversation with the treating physician, not a form filled out at a kitchen table.
“A client's mother had a beautiful directive and no POLST. She was resuscitated against everything she had written, because the responding paramedics had thirty seconds and no physician order in front of them. That is the gap this form exists to close.”
Delia Vasquez-HartHaving both
They are complements, not alternatives. The directive names your agent and covers the wide range of decisions a POLST never addresses. The POLST handles the emergency, right now, without interpretation. A seriously ill patient wants both, and they should say consistent things.
If they conflict, that is a problem worth fixing immediately with the physician who signed the POLST.
Questions we get asked
Can I fill one out myself?
No. It requires a physician, nurse practitioner, or physician assistant signature to be a valid medical order. That signature is what makes it effective.
Can it be changed?
Yes. The patient or their agent can void it and a new one can be completed. Draw a line through the old form and write VOID across it, then destroy extra copies.
Does it replace my directive?
No. It does not name an agent and it does not cover decisions outside the immediate emergency scope. Keep both.
Does a hospital have to follow it?
It is a medical order and is intended to travel with the patient across settings, which is a large part of why the form exists.
If you have a parent in a skilled nursing facility or with a serious diagnosis, ask their physician at the next appointment whether a POLST is appropriate. Bring the directive with you so the two documents can be reconciled in the same conversation.
