DNR, POLST, and the Paperwork That Decides How You Die

Paramedics don’t read minds. They read forms.

When a 911 call comes in for a person not breathing, the default is to do everything: chest compressions, airway, defibrillator, drugs, transport. That default applies to a 38-year-old triathlete and a 94-year-old with end-stage cancer identically, unless the right piece of paper, and it has to be the right one, says otherwise.

Three documents govern this territory. People constantly mistake one for another, and the mistakes only reveal themselves at the worst possible moment. Here’s what each form is, what it isn’t, and where the whole system fails.

The advance directive is the document every adult should have, healthy or not. It typically does two things: states your treatment preferences for scenarios where you can’t speak (the living will part), and names a person to decide for you (the healthcare proxy part).

Know what it is legally: a statement of wishes and an appointment of a decider. It guides doctors and empowers your person. What it is not: a medical order. In a crisis, someone has to find it, read it, interpret sentences like “no heroic measures,” and translate them into orders. Paramedics in your living room at 2 a.m. will not be doing literary analysis. They’ll be doing compressions.

That’s not a flaw, exactly. It’s a scope. The advance directive states your values. The next two documents turn them into orders a clinician can act on.

A Do Not Resuscitate order is a medical order, signed by a clinician, covering exactly one scenario: your heart or breathing stops. It says don’t attempt CPR. That’s the entire document.

A DNR does not mean do not treat. It doesn’t limit antibiotics, surgery, pain control, oxygen, hospitalization, or anything else. Patients with DNRs get full aggressive treatment for everything short of resuscitation every day. Families refuse DNRs because they think it means abandonment. It means one thing: when the heart stops, let it.

Why would anyone choose that? Because CPR is not what television says it is. On TV, most coded patients wake up embarrassed in a clean gown. In reality, roughly one in ten people who arrest outside a hospital survive to discharge, and about a quarter of those who arrest inside one. For the frail elderly with advanced illness, the odds fall further, and the process itself is violent: broken ribs are routine, and survivors often return with less function than before. For some people that gamble is worth it. For others it’s a bad death appended to the end of a long illness. A DNR is how you decline the gamble in advance.

One trap: a DNR entered in your hospital chart lives in the hospital. At home, you need your state’s out-of-hospital DNR form, bracelet, or the next document, or EMS will do what the default demands.

POLST stands for Portable Medical Orders for Life-Sustaining Treatment, though your state may call it MOST (Colorado does), MOLST, or POST. It’s the newest of the three and the one built to fix the gaps.

A POLST is a set of signed medical orders, usually on a single brightly colored page, that follows the patient everywhere: home, ambulance, ER, nursing facility. EMS can act on it directly. No interpretation, no phone tree, no searching a filing cabinet while doing compressions.

It typically covers three decisions. Section A: attempt CPR or not. Section B: if you have a pulse but are in trouble, how far to go, from comfort-focused care only, to selective treatments like antibiotics and IV fluids without ICU, to full treatment. Section C: medically administered nutrition.

Crucially, POLST is not for everyone. It’s designed for people with serious illness or frailty, roughly, anyone whose clinician wouldn’t be surprised if they died within a year. A healthy 45-year-old shouldn’t have one. A healthy 45-year-old should have an advance directive. The POLST comes later, if serious illness arrives, and it gets created in a conversation with your clinician, then signed by them, which is what makes it an order.

It’s three layers with different jobs. The advance directive: everyone over 18, states values, names the decider. The POLST: seriously ill or frail people, turns those values into portable orders. The DNR: the narrow CPR-only instrument, largely folded into POLST where POLST exists, still used on its own plenty of places.

They’re complements, not competitors. The advance directive names who decides and covers the unforeseeable. The POLST handles the foreseeable emergencies of a known illness. When they conflict, the more recent, more specific document generally wins, which is why they should be written together, not in separate decades.

The forms fail in stupid, preventable ways, so here is the prevention.

They fail when nobody can find them. A POLST in a safe deposit box is useless. The convention: original on the refrigerator or by the bed, because that’s where EMS is trained to look. Copies to the hospital, the proxy, the family group chat.

They fail when the family fights them. Legally, a valid POLST is an order. Practically, a distraught spouse screaming “do everything” in the doorway creates chaos no form fully overrides. The fix isn’t better paper. It’s the conversation, held early, so your people are executors of a decision they’ve already heard from your mouth, not first-time readers.

They fail when they’re stale. Preferences change with prognosis. Review after every major health change. POLST forms can be voided and redone in one appointment.

And they fail when they never get written, which is the most common failure of all, because writing them requires admitting the scenario exists. You’ve read this far. The scenario exists.

Advance directive for everyone: wishes and a decider. POLST for the seriously ill: portable orders EMS can follow. DNR: the single-issue instrument covering CPR alone. The paperwork takes an afternoon. The default it replaces is a stranger doing compressions on someone who never wanted them, because nobody wrote anything down. Start with the directive.
