POLST vs DNR vs Advance Directive: Which Document Does Your Parent Actually Need?

If you have ever tried to untangle the alphabet soup of end-of-life documents — POLST, DNR, advance directive, living will, healthcare proxy, medical POA — you are not alone. Most adult children trying to help an aging parent navigate this process hit the same wall: the names sound similar, the purposes overlap slightly, and nobody explains in plain language which ones actually matter and which ones are redundant.

This post lays it out clearly. Four categories of documents, four distinct jobs, and a guide to which ones your parent needs based on their current health situation.

Why So Many Documents Exist

End-of-life planning documents were not designed as a system. They evolved separately — legal documents created by legislatures, medical orders created by hospital systems, and planning tools created by advocacy groups — and they were later layered on top of each other. That is why the language feels inconsistent and why you might encounter four different terms that all seem to mean "instructions about medical care."

The short version: these documents fall into two fundamentally different categories.

• Planning documents are created in advance, while your parent still has capacity. They express wishes and appoint decision-makers. They kick in across multiple situations and settings.
• Medical orders are created by a doctor, usually when a patient is already seriously ill. They are active, signed physician orders — not statements of preference. They travel with the patient.

Understanding this distinction immediately resolves most of the confusion.

The Four Documents: What Each One Does

1. The Advance Directive (Living Will)

What it is: A written statement of your parent's medical treatment preferences, signed and witnessed while they still have capacity. It describes what they would or would not want under specific circumstances — for example, whether they want a breathing machine if they cannot recover, or whether they want tube feeding if they are in a permanent coma.

What it is not: A physician's order. A living will is a guide for doctors and family members, not an instruction that medical staff are automatically required to follow. Its enforceability varies by state.

When it activates: When your parent lacks capacity to speak for themselves and a situation arises that matches what the document describes.

Bottom line: Every adult should have one. It does not require a lawyer for basic versions — many states provide free forms. Without it, doctors default to aggressive intervention and family members are left guessing.

2. The Healthcare Proxy / Medical Power of Attorney

What it is: A document that appoints a specific person — usually a spouse, adult child, or trusted friend — to make medical decisions on your parent's behalf if they cannot make decisions themselves. The terms "healthcare proxy" and "medical power of attorney" (MPOA) are used interchangeably in most states, though some states use one term or the other exclusively.

How it differs from next of kin: "Next of kin" has no legal authority in healthcare. Hospitals consult next of kin informally, but legally, without an MPOA, no single family member has automatic authority. In a crisis, if three adult children disagree about treatment, the hospital may be forced to go to court. An MPOA prevents this by designating one person clearly.

Can the healthcare proxy override the patient? No, while the patient still has capacity. The proxy only steps in when your parent cannot speak for themselves. If your parent regains capacity, their own voice takes over again.

Bottom line: Name a healthcare proxy now, while your parent is well. Choosing this person is one of the most important decisions in the entire planning process. The proxy needs to know your parent's values, not just their specific wishes.

3. The POLST Form (Physician Orders for Life-Sustaining Treatment)

What it is: A set of actual physician's orders — not a planning document — that spells out specific medical interventions for a patient who is already seriously ill. POLST stands for Physician Orders for Life-Sustaining Treatment. In some states it is called MOLST (Medical Orders for Life-Sustaining Treatment), MOST, or TPOPP.

What makes it different from a living will: A living will is a document a person creates. A POLST is a medical order a doctor writes, based on conversations with the patient and family. It is signed by a physician and travels with the patient — to the emergency room, to a new care facility, home.

What it covers: Typically three decisions: (1) whether to attempt CPR if the heart stops, (2) what level of medical intervention to use in other emergencies (full intervention, limited intervention, or comfort care only), and (3) whether to use artificial nutrition.

Who it is for: People who are already seriously ill, elderly with multiple chronic conditions, or those in the last year or two of life. A healthy 70-year-old does not need a POLST — an advance directive is enough. A parent with advanced heart failure, late-stage dementia, or a terminal diagnosis does need one.

Why it matters: Emergency responders and hospital staff can act on a POLST immediately. Without it, an EMS team arriving at your parent's home is legally required to begin CPR, even if your parent's living will says they do not want it. The POLST bridges that gap.

4. The DNR Order (Do Not Resuscitate)

What it is: A specific type of physician's order instructing medical staff not to perform CPR if the patient's heart stops. A DNR is actually a subset of the POLST — it is one checkbox on the POLST form in most states that have adopted POLST.

The important distinction: A DNR does not mean "do nothing." It means only that CPR will not be attempted. A patient with a DNR still receives pain medication, IV fluids, oxygen, antibiotics, and all other treatments — unless those are separately addressed in a POLST or advance directive.

What "AND" means: Some hospitals and states use the term AND — Allow Natural Death — instead of DNR. It is considered more humane language that focuses on what will happen (a natural death) rather than what will not (resuscitation). Both terms refer to the same medical order.

Who creates it: A physician, after a conversation with the patient or their authorized decision-maker. Your parent cannot simply write their own DNR — it must be a signed medical order.

Which Documents Does Your Parent Actually Need?

Use this framework based on your parent's current health situation.

If your parent is healthy and independent (65-75, no serious illness)

• Advance directive: Yes — essential
• Healthcare proxy / Medical POA: Yes — essential
• POLST: Not yet needed
• DNR: Not applicable

If your parent has serious chronic conditions or is frail (multiple diagnoses, frequent hospitalizations)

• Advance directive: Yes — update if already exists
• Healthcare proxy / Medical POA: Yes — confirm it is current and accessible
• POLST: Yes — discuss with their primary care doctor
• DNR: Yes, if POLST includes this preference

If your parent has a terminal diagnosis or advanced dementia

• Advance directive: Yes — but POLST now takes operational priority
• Healthcare proxy / Medical POA: Yes — this person needs to be actively engaged with care team
• POLST: Yes — critical. Must be visible, travel with parent
• DNR: Part of POLST — needs explicit decision

The Documents That Do Not Overlap

One of the most common misconceptions: "My parent has a living will, so we're covered."

A living will describes preferences, but it does not appoint a decision-maker (that is the healthcare proxy's job) and it does not create a medical order (that is the POLST's job). All three serve different functions and all three should be in place by the time a parent has any serious health condition.

Similarly, appointing a healthcare proxy does not mean you can skip the advance directive. The proxy is a person. The advance directive gives that person a written guide — your parent's actual stated wishes — to refer to when making decisions under pressure.

Where to Get These Documents

• Advance Directive: CaringInfo (caringinfo.org) provides free, state-specific forms. The "Five Wishes" document ($5) is accepted as a legal advance directive in 42 states and is written in plain language.
• Healthcare Proxy / Medical POA: Your state health department's website offers free forms. A lawyer is not required for most people with straightforward situations.
• POLST: Must be completed with a physician. Ask your parent's primary care doctor to begin the conversation at the next appointment.
• DNR: Same process — physician-initiated, based on your parent's preferences.

The Right Order of Operations

1. Start with the advance directive and healthcare proxy — these are the foundation, and your parent can complete them independently while they are well.
2. Once those are in place, have a conversation with their doctor about whether a POLST is appropriate given their current health status.
3. Make sure all documents are accessible — not locked in a safe deposit box. Key people (the proxy, the primary care doctor, any specialists) should have copies. If your parent moves between care settings, the POLST must travel with them.

Keeping It All Organized

Gathering these documents is one thing. Keeping them organized, updated, and accessible to the right people is another challenge entirely. The End-of-Life Planning Workbook walks you through each document category, provides prompts for the conversations that need to happen before signing anything, and includes a document locator system so that nothing gets lost in a filing cabinet when it matters most.
