A DNR (do not resuscitate) order is related to advance directives but is not the same thing. An advance directive is a legal document you create to outline your wishes for medical care if you can’t speak for yourself. A DNR is a medical order, signed by a physician, that specifically instructs healthcare staff not to perform CPR if your heart or breathing stops. Think of it this way: an advance directive is something you write, while a DNR is something a doctor writes based on your wishes.
What an Advance Directive Covers
An advance directive is a broad legal document that captures your preferences for medical care across a range of scenarios. It only goes into effect if you lose the ability to communicate your own wishes, whether from a coma, serious injury, terminal illness, or severe dementia. Most people create advance directives with a lawyer or family member, and only about 7% involve a physician in the drafting process.
There are two main types. A living will spells out the specific treatments you do or do not want, such as mechanical ventilation, feeding tubes, or dialysis. A healthcare proxy (sometimes called a durable power of attorney for healthcare) names a person you trust to make medical decisions on your behalf. You can have both, and most experts recommend it.
What a DNR Order Actually Is
A DNR is narrower in scope. It addresses one specific situation: what happens if your heart stops beating or you stop breathing. A DNR becomes part of your medical chart and tells hospital or nursing facility staff not to attempt CPR or other life-support measures in that moment. Without a DNR on file, medical teams will make every effort to restore your heartbeat and breathing.
The critical distinction is who creates it. A living will is signed by you and two witnesses. A DNR requires a physician’s signature to be valid. In many states, the out-of-hospital version also requires two witnesses plus signatures from both you (or your representative) and your doctor. A form missing any of these signatures is not considered valid.
A DNR does not affect any other treatment. If you have a DNR, you still receive medications, surgery, or any other care you need. It only applies at the moment of cardiac or respiratory arrest.
Why the Distinction Matters in Emergencies
This is where the difference between the two documents has real consequences. When paramedics arrive at your home during a cardiac arrest, they need clear, portable documentation telling them not to resuscitate. A living will tucked in a filing cabinet may not help.
A recent review of EMS protocols across the United States found that only 50% of state protocols allowed paramedics to honor a standard advance directive, and just 13% accepted living wills as sufficient DNR documentation. By contrast, 76% of EMS protocols recognized portable medical orders like a POLST form, and 61% accepted DNR jewelry or bracelets. Researchers recommended that EMS protocols prioritize portable medical orders over advance directives and living wills because they are concise, designed for emergency use, and immediately recognizable.
In practical terms, if you want your wishes honored outside a hospital, you need more than just an advance directive. You need a physician-signed medical order that travels with you.
POLST and MOLST: Bridging the Gap
Many states now use a form called POLST (Physician Orders for Life-Sustaining Treatment) or MOLST (Medical Orders for Life-Sustaining Treatment) to solve the portability problem. These forms translate your goals and preferences into actionable medical orders that follow you across every setting: hospitals, nursing homes, hospice, assisted living, and your own home.
A POLST or MOLST form is designed to complement traditional advance directives, not replace them. In New York, for example, the MOLST is the only authorized form for documenting both out-of-hospital DNR and do-not-intubate orders. One important difference from a standard advance directive: a POLST takes effect as soon as you consent to it and a physician signs it. It is not conditional on losing the ability to make decisions. Your advance directive, by contrast, only activates when you can no longer speak for yourself.
How the Two Documents Work Together
Your advance directive is the foundation. It captures your values, your preferences for a wide range of treatments, and the person you trust to advocate for you. A DNR order, or a broader POLST form, is the clinical tool that turns part of those wishes into standing medical orders that healthcare workers can act on immediately.
Someone with a serious or terminal illness might have all three: a living will outlining their overall care preferences, a healthcare proxy naming a decision-maker, and a POLST form containing specific physician orders including a DNR. Someone younger and healthy might start with just an advance directive and add medical orders later if their health changes.
Changing or Canceling Either Document
You can revoke or update an advance directive at any time, as long as you still have the capacity to make decisions. The process varies by state but typically involves creating a new document that supersedes the old one, or simply destroying the original and notifying your healthcare proxy and doctor.
Canceling a DNR is also straightforward. You can tell your physician you no longer want the order in place, and they will remove it from your chart. If you have a POLST form, your doctor can update or void it during a conversation about your current goals. The key point is that neither document locks you in. Your preferences can evolve, and the paperwork should evolve with them.
