POLST and Do-Not-Resuscitate Orders: How They Differ From a Living Will

The difference is who signs and when it operates. A POLST — Portable Orders for Life-Sustaining Treatment, called MOLST, POST, MOST or something else depending on the state — and a do-not-resuscitate order are medical orders signed by a clinician. They direct care now, and a paramedic standing in a living room can act on one. A living will is a directive signed by the person, and it speaks only if that person later cannot. Both matter. Confusing them is how people end up receiving treatment they documented that they did not want.

Orders versus directives

The practical consequence is stark. Paramedics responding to a cardiac arrest generally cannot pause to interpret a directive that turns on whether a person is "terminal" — they need a signed order they are authorized to follow. That is the gap portable orders fill.

Note: These instruments complement each other. A person with serious illness commonly has all three: a health care agent, a living will, and a POLST. Signing a POLST does not revoke a directive.

What a POLST covers, and who it is for

A POLST is meant for a defined group: people with a serious progressive illness, advanced frailty, or a condition where a change of clinical status is reasonably foreseeable. It is not routine paperwork for a healthy adult, and pushing it downstream to people who are not in that group is a recognized problem with the model.

The form is built around a conversation. The clinician documents what treatments the patient wants in light of their actual prognosis, then signs orders reflecting it. Most state versions address at least:

• Whether to attempt cardiopulmonary resuscitation if the person has no pulse and is not breathing.
• The overall level of intervention wanted otherwise — comfort-focused care, selective treatment, or full treatment.
• In many states, whether artificially administered nutrition is wanted, and for how long.
• Who took part in the conversation: the patient, or a surrogate acting for them.

Programs are state-specific. Form names, colours, whether a nurse practitioner or physician assistant may sign, whether a registry exists, and how EMS is trained to respond all vary. Facilities that participate in federal programs also have obligations to ask about advance directives, an obligation traceable to federal law and administered through the Centers for Medicare & Medicaid Services.

DNR orders inside and outside a hospital

A do-not-resuscitate order is narrower than a POLST. It addresses one question — whether CPR will be attempted — and says nothing about antibiotics, hospital transfer, or feeding.

The distinction that trips families up is location. An in-facility DNR is written into the chart and governs care in that hospital or nursing home. It does not automatically travel home with the patient. Many states therefore have a separate out-of-hospital DNR, sometimes accompanied by a bracelet or wallet card, that authorizes EMS to withhold resuscitation in the community.

Watch out: A DNR is not an instruction to withhold other care. It does not mean no pain relief, no oxygen, no antibiotics and no hospital transfer. Where a broader instruction is intended, that belongs in a POLST or in the treatment plan, stated explicitly.

What the living will and the agent actually do

A living will records what the person wants if they cannot decide and a defined condition applies — commonly a terminal condition, permanent unconsciousness, or an end-stage condition as the state statute describes it. Its weakness is that real situations rarely match the categories cleanly.

That is why naming a health care agent matters more. An agent can respond to facts nobody anticipated, argue with a clinician, and consent or refuse in real time. Most states combine the two in a single advance directive document, and the Uniform Law Commission's health-care decisions work is the source of much of that structure.

Financial authority is separate. A health care agent cannot pay bills, and a financial agent cannot consent to surgery — the boundary explained in our guide to the scope of a power of attorney. If nobody has been named and capacity is gone, decisions fall to a default surrogate under state law or to a court, the route described in our explainer on adult guardianship and its alternatives.

Portability, revocation, and the failures that recur

Most states honour an advance directive validly executed in another state, either by statute or by practice. Portable orders are less reliable across state lines, because EMS protocols are set locally; a form from one state may be honoured, questioned, or ignored in another.

Revocation is easy and often overlooked. A patient with capacity can revoke a POLST or DNR verbally, on the spot, and their spoken instruction controls over the paper. Forms should also be revisited when the person's condition changes materially, when they move between facilities, and after any hospitalisation.

The recurring practical failures are mundane: the form is in a drawer instead of somewhere responders look, the facility's copy was never updated, or nobody told the agent the form existed. Long-term care facilities have their own documentation duties, covered in our guide to nursing home admission agreements and residents' rights, and the programs paying for that care are administered through the agencies listed at Medicaid.gov.

Common questions

If I have a living will, do I still need a POLST?

Only if you are in the group POLST is designed for — serious illness or advanced frailty where an acute change is foreseeable. A healthy adult with a directive and a named agent generally does not need one, and clinicians are discouraged from completing forms outside that population. When illness progresses, the conversation should happen again, because the POLST reflects the current prognosis rather than a general preference.

Can my family override the form after I lose consciousness?

Not by preference alone. A valid order or directive is meant to control, and clinicians follow it. In reality, families do sometimes object at the bedside, and clinicians facing a conflict may seek review or involve an ethics committee. Naming an agent and telling that person exactly what you want is the strongest protection, because a designated decision-maker outranks an informal family consensus.

Who pays for the conversation with the doctor?

Advance care planning discussions are a recognized clinical service, and coverage information is published by Medicare for people enrolled in that program. Coverage rules and any cost sharing change, so the program page is the reliable source rather than a summary. Many hospitals and hospices also offer planning support at no charge through social work or chaplaincy staff.

What happens if the form cannot be found in an emergency?

Responders treat. Emergency medical services default to full resuscitation when no valid order is present, and they cannot delay to search a house. That is why states use bright colours, standard placement — often the refrigerator door or the front of a chart — bracelets, and in some places electronic registries. A copy stored only in a safe deposit box or a lawyer's file has no practical effect.

Getting the paperwork to actually work

1. Name an agent first. A person who can respond to the unexpected is worth more than any form describing scenarios.
2. Write the directive. Follow the state's execution requirements for witnesses or notarisation exactly; defects are the common reason a document is questioned.
3. Ask about a portable order only if it fits. Raise POLST with the treating clinician when illness is serious or advancing, not as routine planning.
4. Check the out-of-hospital question. If the goal is that paramedics not resuscitate at home, confirm which document your state's EMS will actually honour.
5. Distribute copies. Agent, primary clinician, each facility, and one visible copy at home. Add the state registry if there is one.
6. Re-check after every hospitalisation. Orders written during one admission can conflict with what is on the refrigerator door.

Practical step: Ask the treating clinician one direct question — "if my heart stopped tonight at home, what would the paramedics do with the paperwork I have?" The answer reveals immediately whether the documents in place are orders or only directives.
