POLST vs. Advance Directive: Which Do You Need?

Here's the difference in one breath: an advance directive is a planning document that any adult can complete, while a POLST is a medical order, signed by a clinician, for people who are already living with a serious illness. The advance directive says who speaks for you and what you'd want someday. The POLST tells medical teams what to do right now.

If you're healthy, you need an advance directive. If you're seriously ill, you likely need both. Let's walk through why.

What an Advance Directive Does

An advance directive is a legal document for any adult, healthy or not. In Oregon, the state's form lets you:

• Name a health care representative to make decisions if you can't
• Describe the kinds of care you would or wouldn't want in future situations

It's free, and it doesn't require a lawyer or notary to be valid in Oregon, just proper signing and witnessing per the form's instructions. We cover the whole process in our guide to completing an Oregon advance directive.

Think of it as instructions for a future that may never arrive. It only comes into play if you lose the ability to make your own decisions, and it works through your representative and your doctors, who interpret your wishes for the situation at hand.

What a POLST Does

POLST stands for Portable Orders for Life-Sustaining Treatment. It's not a wish list; it's a set of medical orders, signed by a physician, nurse practitioner, or physician assistant, that emergency responders and medical staff can act on immediately.

A POLST typically addresses questions like:

• Do you want CPR attempted if your heart stops?
• Do you want to be taken to the hospital, or treated where you are?
• How aggressive should medical interventions be?

POLST is intended for people with serious illness or advanced frailty, people for whom these questions aren't hypothetical anymore. It came out of exactly that need: Oregon clinicians saw that patients' end-of-life wishes weren't surviving the trip between care settings, and the POLST model was created here in Oregon before spreading across the country. Oregon also maintains a POLST registry so the orders can be found when they're needed. You can read more about how the state's system works in our article on Oregon's POLST program.

Side by Side

	Advance directive	POLST
Who it's for	Any adult	People with serious illness or frailty
What it is	Legal planning document	Medical order
Who signs it	You, with witnesses	You (or your representative) and a clinician
When it applies	If you can't speak for yourself	Right now, in an emergency
Names a decision-maker?	Yes	No
Followed by EMS?	Not directly	Yes, it's an order

That last row matters more than people expect. In an emergency, responders need orders they can act on in seconds. An advance directive is a document to be read and interpreted; a POLST is an order they can follow on the spot.

Which One Do You Need?

If you're a healthy adult: complete an advance directive. That's the document for you. A POLST wouldn't be appropriate yet, and most clinicians won't complete one for a healthy person.

If you or your loved one has a serious illness: you'll likely want both. The advance directive names your decision-maker and covers the situations a POLST doesn't address. The POLST converts your current wishes, about CPR, hospitalization, and intensity of treatment, into orders that travel with you between home, hospital, and facility.

If you're already on hospice: your hospice team will usually raise the POLST conversation early, because it protects your choices in exactly the moments hospice is designed for. Choosing comfort-focused care and having that choice honored at 2 a.m. are two different things; a POLST closes that gap.

One common point of confusion: a POLST can include a do-not-resuscitate order, but the two aren't the same thing. If the terminology is getting tangled, our plain-language explainer on DNR orders sorts it out.

Can You Change Your Mind?

Yes, with both documents. You can replace your advance directive at any time while you can make your own decisions. A POLST can be revised or voided through a conversation with your clinician whenever your goals change. Neither document locks you in; they record your current wishes so others can honor them.

How Engrace Hospice Can Help

These forms work best when they grow out of an honest conversation, and that's something our team does every day. Our nurses and social workers can explain both documents at your kitchen table, help your family talk through the choices, and coordinate with your physician when a POLST is appropriate. We're locally owned, based in Pendleton, and we serve families across Umatilla County, Morrow County, and Eastern Oregon. Our advance care planning page is a good place to start.

Frequently Asked Questions

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

An advance directive is a legal document any adult can complete to name a decision-maker and describe future care wishes. A POLST is an actual medical order, signed by a clinician, that tells emergency and medical staff what treatments to provide right now. POLST is meant for people who are already seriously ill.

Do I need both a POLST and an advance directive?

Many people with serious illness benefit from both. The advance directive names who speaks for you and covers situations a POLST doesn't, while the POLST turns your current treatment wishes into orders that emergency responders can follow immediately.

Does every adult need a POLST?

No. POLST is designed for people with a serious illness or advanced frailty, not for healthy adults. A healthy adult planning ahead needs an advance directive; a POLST comes later, if and when illness makes specific treatment orders appropriate.

Who signs a POLST form?

A POLST is signed by a clinician, because it is a medical order. It is completed through a conversation between you (or your representative) and your doctor, nurse practitioner, or physician assistant about the treatments you do and don't want.
