Types of Advance Directives: Which Documents Does Your Parent Need?

The phrase "advance directive" is used loosely — sometimes to mean a living will, sometimes a healthcare proxy, sometimes a bundle of all end-of-life documents. This ambiguity causes families to complete one document and assume they are finished, when in reality they may have addressed only a fraction of what needs to be documented.

This guide explains each type of advance directive, what it covers, and which ones your aging parent is most likely to need.

What Makes a Document an "Advance Directive"?

An advance directive is any legal document that expresses a person's healthcare preferences or appoints a decision-maker in advance of incapacity. The term is an umbrella — it encompasses several distinct documents, not just one.

The confusion arises because different states use different terminology for the same concepts, and because the word "advance directive" sometimes refers specifically to a written statement of treatment preferences (what some states call a living will) and sometimes to the broader category.

Here is a breakdown of the main types.

Type 1: Living Will (Written Treatment Preferences)

A living will is a written statement in which your parent specifies what medical treatments they do or do not want if they become unable to make their own decisions. It typically addresses:

• Cardiopulmonary resuscitation (CPR) — whether to attempt CPR if the heart stops
• Mechanical ventilation — whether to use a breathing machine if they cannot breathe independently
• Artificial nutrition and hydration — feeding tubes and IV fluids if they cannot eat or drink
• Dialysis — kidney dialysis if the kidneys fail
• Hospitalization — whether to transfer to a hospital or remain in a care setting

Most living wills also include a values statement — the conditions under which these preferences apply. For example: "I do not want mechanical ventilation if I am in a permanent vegetative state and there is no reasonable expectation of recovery."

What a living will cannot do: It can only address situations your parent specifically anticipates. It does not give anyone legal authority to act — it records wishes only. For that authority, a separate document is needed.

Terminology by state: What most states call a "living will" may appear under different names. In some states it is called an "Healthcare Declaration," "Directive to Physicians," or "Natural Death Declaration." The function is the same.

Type 2: Healthcare Power of Attorney (Healthcare Proxy / Medical POA)

A healthcare power of attorney (also called a healthcare proxy or medical POA) is a legal document that appoints a specific person — called an agent, proxy, or surrogate — to make medical decisions on your parent's behalf when they cannot.

This is the decision-making authority document. The agent can:

• Consent to or refuse specific treatments
• Choose among treatment options when physicians offer choices
• Decide when to pursue or discontinue life support
• Direct the care team to follow the living will
• Make decisions in situations the living will did not anticipate

Why both documents are needed: A living will without a healthcare proxy leaves gaps — the document cannot address every scenario, and there is no one with legal authority to fill in those gaps. A healthcare proxy without a living will burdens the agent with guessing at the principal's wishes. Both together create a complete system.

Naming it right: In most states, you can combine the living will and healthcare proxy into a single document — sometimes called a "combined advance directive" or "durable power of attorney for health care." Some states have standardized forms that include both elements.

Type 3: POLST Form (Physician Orders for Life-Sustaining Treatment)

The POLST form is different in nature from the above — it is a physician order, not a planning document. POLST stands for Physician Orders for Life-Sustaining Treatment. It goes by different acronyms in different states: MOLST (New York, Maryland), MOST (North Carolina), TPOPP (Tennessee), POST (several western states).

Unlike a living will, which records preferences, a POLST is signed by the patient's physician and immediately actionable by emergency medical services, hospital staff, and care facilities. If EMS arrives and the patient cannot speak, they are legally required to follow a valid POLST form.

A POLST typically addresses three clinical questions:

1. Should CPR be attempted if the heart stops?
2. What is the appropriate level of medical intervention (full intervention, limited intervention, or comfort-focused care only)?
3. Should artificial nutrition be provided?

Who needs a POLST? The POLST is intended for people with serious illness, advanced frailty, or a limited life expectancy — not for general advance planning for healthy older adults. For a parent with advanced cancer, COPD, heart failure, or advanced dementia, a POLST translates their wishes into enforceable clinical orders.

Who does not need a POLST? A healthy 70-year-old who is planning ahead does not need a POLST today. They need a living will and healthcare proxy. The POLST becomes relevant when clinical circumstances change.

Type 4: DNR / DNI Orders

A Do Not Resuscitate (DNR) order and Do Not Intubate (DNI) order are physician-signed clinical orders that direct care providers not to attempt CPR or mechanical ventilation, respectively. They are similar to POLST forms but narrower in scope.

A DNR/DNI is typically issued at a specific care setting (hospital, nursing home) and may not transfer across settings. A POLST form is portable and follows the patient. When a POLST is available, it generally replaces the need for separate DNR/DNI orders.

Important distinction: A DNR is not the same as a "do nothing" or "comfort care only" order. A patient with a DNR can still receive all other treatments, including surgery, IV medications, blood transfusions, and chemotherapy. It addresses only the single intervention of resuscitation.

Type 5: Psychiatric Advance Directive

A psychiatric advance directive (PAD) is a specialized document for individuals with serious mental illness. It allows a person to specify in advance what psychiatric treatments they do or do not consent to — including specific medications, hospitalization, and electroconvulsive therapy — during a mental health crisis when they may lack capacity.

PADs are less commonly discussed but highly relevant for families caring for a parent with serious mental health conditions. Approximately 25 US states have specific statutes recognizing psychiatric advance directives.

Type 6: Five Wishes

Five Wishes is a specific document created by Aging with Dignity that functions as a legally valid advance directive in 42 US states. It is notable for addressing not just clinical preferences but personal and emotional wishes: who the patient wants present, how they want to be treated, what comforts matter to them, and what they want said at the end. It is written in plain language and designed to be completed without an attorney.

For families looking for a single comprehensive document that covers both the clinical and the human dimensions of end-of-life care, Five Wishes is worth considering.

The Window for Getting These in Place

Every one of these documents — with the exception of the POLST form, which requires physician involvement — can and should be completed while your parent is healthy and thinking clearly. The legal requirement is capacity: your parent must understand what they are signing and its effect.

Once cognitive decline reaches a certain threshold, it may be legally too late to execute a valid living will or healthcare proxy. At that point, the family faces the court system for guardianship — a slow, public, expensive process that strips the parent of autonomy and the family of flexibility.

The conversation does not have to happen all at once. Many families start with a general discussion of values, then complete the documents over several sessions. The important thing is to start now.

The End-of-Life Planning Workbook provides structured conversation guides, plain-English explanations of each document, and worksheets to record your parent's wishes clearly — so when the time comes, you are not making decisions in a panic.

Summary: The Documents That Matter Most

For most aging adults, the essential advance directive package is:

1. Living will — Written treatment preferences (what they want and do not want)
2. Healthcare power of attorney — Designated decision-maker (who has authority)
3. POLST form — Physician orders (actionable by EMS and care facilities) — when clinically appropriate
4. Durable financial power of attorney — Separate from the above, but equally critical for financial continuity

If your parent has completed all four of these, the family has the foundation they need to navigate whatever comes.
