POLST vs. Advance Directive: The Form Paramedics Can Actually Follow

It’s 3 a.m., the paramedics are in the living room, and her living will — the one that says no CPR — is in a drawer upstairs. They start compressions anyway. Not because they’re careless, but because a living will is a legal document, and what paramedics follow is a medical order. There’s a form built for exactly this gap. Most families have never heard of it, and half the confusion is that it goes by a different name in almost every state.

The form is called a POLST — physician orders for life-sustaining treatment — and the fastest way to understand the whole POLST vs advance directive question is this: an advance directive is her wishes, and a POLST is a doctor’s orders based on her wishes. Like a prescription, it’s written and signed by a clinician, which is precisely why emergency responders can act on it on the spot. This page explains what it is, who actually needs one (most people don’t — yet), why it complements the advance directive instead of replacing it, and what it’s called where she lives.

What is a POLST, in plain terms

So what is a POLST, exactly? It’s a portable medical order that turns a seriously ill person’s treatment wishes into instructions clinicians act on immediately — in the ambulance, the emergency room, the nursing home, wherever she is. The idea started in Oregon in the 1990s, when clinicians kept watching patients’ end-of-life wishes get lost between care settings, and it has since spread to nearly every state.

Three things make it different from every other document in the folder:

• A clinician signs it. A POLST is completed and signed by a physician, nurse practitioner, or physician assistant who has a treating relationship with the patient — after a real conversation about her condition, her prognosis, and what she wants. Depending on the state, the patient or her decision-maker signs too (required in some states, strongly encouraged in others).
• It gives orders, not guidance. The core of the physician orders for life-sustaining treatment form is a set of checked boxes: Section A — if she has no pulse and isn’t breathing, attempt CPR or do not attempt resuscitation (allow natural death). Section B — if she’s alive but in crisis, full treatment, limited treatment, or comfort measures only. There’s no interpreting committee at 3 a.m.; the box is the answer.
• It’s built to be found and followed. The POLST form is printed on brightly colored paper in most states — ultra pink in California, green in New Jersey — kept somewhere responders look (the refrigerator is the classic spot), and sent with her at every transfer or discharge. Photocopies and faxes are valid. In states like California, the law requires providers to follow it and protects those who comply in good faith.

And the part that keeps it humane: a POLST is always voluntary. Nobody can require her to have one, she can change or revoke it at any time — verbally or in writing — and any section left uncompleted defaults to full treatment. It’s a floor of protection, not a ceiling on care.

POLST vs advance directive: two different jobs

Families constantly ask whether a POLST is the same as a living will. It isn’t — and the difference is exactly why the paramedics in the opening paragraph did compressions. Here’s the whole comparison in one place:

The two documents are partners, not rivals. The advance directive is the foundation — it names her health care agent, the person who can respond to situations no form anticipated, and it’s the document every adult should have regardless of health. The POLST is the sharp end — it exists so that in the two minutes that decide everything, nobody is searching a drawer or phoning a lawyer. A POLST does not replace the advance directive — California’s form states that on its face — and a family that needs a POLST almost always needs both. If the advance directive isn’t done yet, start there: the advance directives hub walks every document, state by state →.

Who should have one — and who shouldn’t yet

This is where POLST differs from everything else on this site’s advance-directives shelf: it is not for everyone. A POLST is designed for people living with serious illness or advanced frailty — the practical shorthand clinicians use is whether they’d be unsurprised if this were the final year or two of life. Advanced heart failure, late-stage COPD, advancing dementia, metastatic cancer, the frailty that follows repeated hospitalizations: that’s POLST territory.

If she’s a healthy 72-year-old, she doesn’t need a POLST — and a thoughtful clinician won’t write one. Checking boxes about resuscitation years before the clinical picture exists means ordering treatment decisions in the dark. For a healthy adult, the advance directive does the planning job on its own. The POLST conversation belongs at the moment the illness gets serious — often raised by a palliative care team, a hospice, or her own physician. If you’re weighing what those layers of care even mean, palliative care vs. hospice explains the difference →.

The name problem: POLST, MOLST, MOST, POST

Here’s the source of half the Google confusion: the same idea wears a different name in almost every state. New Jersey uses POLST — its green “Practitioner Orders for Life-Sustaining Treatment” form, signed by a physician, APN, or PA. New York uses MOLST — Medical Orders for Life-Sustaining Treatment. Pennsylvania uses POLST. Elsewhere you’ll meet MOST (Medical Orders for Scope of Treatment), POST, and a few other variants. If a nurse says “MOLST” and you’ve been reading about “POLST,” you are not missing a new document — it’s the same tool in local dress.

Two things follow from that. First, only your state’s version counts. A national POLST organization published a standardized model form in December 2025 that states can adapt — but a form is only legally valid in a state when it’s the version that state has approved, so always use the one her clinician or state health department provides. Second, the landscape moves: Massachusetts, for example, is in the middle of switching from MOLST to POLST, with existing MOLST forms still honored during the transition. When in doubt, her doctor’s office knows exactly which form their state uses — that’s the shortcut.

How to actually get one — and keep the documents talking to each other

There’s no download-and-sign path here, and that’s by design. A POLST begins as a conversation with her physician, nurse practitioner, or physician assistant — about her condition, what treatments actually offer at this stage, and what she wants. The clinician fills in the orders, signs, and depending on the state, she or her health care agent signs as well. Then the logistics that make it work: original on the fridge or somewhere equally findable, a copy in her chart, and the form goes with her at every transfer.

One last piece of housekeeping that prevents real trouble: keep the POLST and the advance directive in agreement. If the two ever conflict, clinicians will confirm her current wishes and follow the most recently documented ones — but the 3 a.m. version of that reconciliation is messy, so don’t leave it to 3 a.m. Good practice is to review the POLST whenever her condition changes meaningfully, whenever she transfers between settings, and whenever her preferences shift. She can update or revoke it at any point; the newest documented decision wins.

Questions families ask

What is a POLST form?

A POLST form is a portable medical order, signed by a physician, nurse practitioner, or physician assistant, that states which life-sustaining treatments a seriously ill or frail person does and does not want — including CPR, and full, limited, or comfort-focused treatment. Because it is a signed medical order rather than a legal document, emergency responders and hospitals can follow it immediately in any setting. POLST stands for physician orders for life-sustaining treatment, though the exact name varies by state.

What is the difference between a POLST and an advance directive?

An advance directive is a legal document any adult signs to state their wishes and name a health care agent, while a POLST is a medical order a clinician signs for someone who is already seriously ill or frail, turning those wishes into instructions emergency responders can act on immediately. An advance directive guides doctors and the agent after interpretation; a POLST is effective on sight, which is why paramedics can follow a POLST but generally cannot act on a living will. The two documents complement each other, and most people who need a POLST should have both.

Is a POLST the same as a DNR?

No — a do-not-resuscitate order is a single instruction about CPR, while a POLST covers CPR and also broader treatment decisions, such as whether to pursue full treatment, limited treatment, or comfort measures only. A POLST can include a do-not-resuscitate order in its CPR section, or it can order that resuscitation be attempted. It is a more complete picture of what care the person wants in a medical crisis.

Who should have a POLST?

A POLST is intended for people who are seriously ill or living with advanced frailty — often described as those whose clinician would not be surprised if they were in the last year or two of life. Healthy adults should not have a POLST; for them, an advance directive is the appropriate planning document. The POLST conversation usually begins with the person’s physician, palliative care team, or hospice when the illness reaches that stage.

What is a MOLST form?

A MOLST form — Medical Orders for Life-Sustaining Treatment — is the name New York and some other states use for the same kind of portable medical order known elsewhere as a POLST. Other states call it a MOST or POST form. The name and exact form vary by state, and only the version approved in the person’s own state is valid there, but the purpose is identical: turning a seriously ill person’s treatment wishes into orders clinicians can follow immediately.

Does a POLST replace an advance directive?

No — a POLST complements an advance directive and is not intended to replace it, and California’s official form states this on its face. The advance directive names the health care agent and records broader wishes, while the POLST turns current treatment decisions into medical orders. Families should keep the two consistent, because if they ever conflict, clinicians will confirm the person’s current wishes and follow the most recently documented decision.

Can a POLST be changed?

Yes — a POLST is always voluntary and can be modified or revoked by the patient at any time, verbally or in writing. It should be reviewed whenever the person’s condition changes meaningfully, whenever they transfer between care settings, and whenever their treatment preferences change. The most recently documented wishes are the ones clinicians follow.
