TL;DR — Key Takeaways

• An advance health care directive is a planning document everyone should have. It names a healthcare agent and states your wishes if you can’t communicate.
• A POLST (Physician Orders for Life-Sustaining Treatment) is a medical order signed by a physician for seriously ill or frail patients. It directs emergency responders and clinicians.
• You don’t pick one or the other. If you’re seriously ill, you need both. If you’re healthy, you need the advance directive.
• Only a physician, nurse practitioner, or physician assistant can sign a POLST in California. The patient (or their surrogate) signs alongside.
• POLST forms are recognized statewide and travel with the patient between care settings. Advance directives must be located when needed.

What Is a POLST Form and Who Needs One?

POLST stands for Physician Orders for Life-Sustaining Treatment. It’s a single-page bright-pink medical order in California, signed by a physician, nurse practitioner, or physician assistant, that directs emergency medical care for a seriously ill patient.

POLST is for people with serious illness or advanced frailty — generally those who would not be surprised if they died within the next year or two. It’s not for healthy adults. The form translates a patient’s preferences into actionable medical orders that paramedics, ER staff, and other clinicians must follow.

The form covers three areas: whether to attempt CPR, the level of medical intervention (full treatment, selective treatment, or comfort-focused care), and whether to use artificial nutrition.

How Does a POLST Differ From a Healthcare Directive?

An advance health care directive is a planning document. It names someone (your healthcare agent) to make decisions if you can’t, and it states your general preferences for end-of-life care. It’s signed by you, witnessed or notarized, and effective if you become incapacitated.

A POLST is a medical order. It’s signed by a healthcare provider after a conversation with the patient (or their surrogate) about goals of care. It applies right now, regardless of capacity, and binds the medical team in real time.

The difference matters in an emergency. If you’re found unconscious, paramedics will start CPR by default. An advance directive doesn’t stop them — it’s a planning document, not a medical order, and they’re often not allowed to follow it without provider verification. A POLST does stop them, because it’s a physician’s order they’re trained to honor on the spot.

Which Document Should I Have in California?

Every California adult should have an advance health care directive. It’s a foundational estate planning document, in the same category as a will or a trust. You need one whether you’re 25 and healthy or 85 and frail.

A POLST makes sense once you have a serious illness or advanced frailty. Indications include: a diagnosis with limited life expectancy, advanced dementia, multiple hospitalizations in the last year, or a clear shift toward comfort-focused care. Your physician should bring it up at the right time. If they don’t, you can ask.

You don’t replace one with the other. If you have a POLST, you should also have an advance directive that covers situations the POLST doesn’t address — like which agent should make decisions about non-life-sustaining treatment, or what to do about a feeding tube months into a recovery.

Can You Have Both a POLST and an Advance Directive?

Yes, and seriously ill patients usually should. The two documents work together.

The advance directive names your agent and gives them the broader decision-making authority. It speaks to long-range scenarios and personal values. The POLST is the immediate, emergency-actionable order for the current illness.

When the documents conflict, California generally treats the POLST as controlling for the specific medical interventions it addresses, because it’s the more recent and more specific instruction signed by both the patient and the provider.

Both documents should be reviewed together when there’s a major change in condition or goals of care.

Who Can Sign a POLST in California?

California POLST forms must be signed by both a healthcare provider and the patient (or the patient’s legally recognized surrogate). The provider must be a physician (MD or DO), nurse practitioner, or physician assistant licensed in California.

The patient signs to confirm the orders reflect their wishes. If the patient lacks capacity, their healthcare agent under an advance directive can sign. If there’s no agent, the patient’s legally recognized surrogate decision-maker (typically a spouse, adult child, or other close family member) can sign on the patient’s behalf, following California’s surrogate decision-making hierarchy.

Without both signatures, the POLST is generally not valid as a medical order.

How to Make Sure Your POLST Actually Gets Followed

Visibility matters. The bright-pink color isn’t decorative — it’s designed so paramedics can spot the form in seconds. Keep it on the refrigerator door, the headboard, or another prominent location at home. Bring it to every medical appointment and hospital admission.

California maintains an electronic POLST registry that providers can query in emergencies. Make sure your POLST is registered if your provider participates. [VERIFY: current status of California eRegistry POLST rollout.]

Tell your healthcare agent and family where the POLST is. Give a copy to your primary care physician, your home health agency, and any facility where you receive care.

When to Update or Revoke a POLST

POLST orders should be reviewed when your condition changes substantially, when you transfer between care settings (hospital to skilled nursing, for example), or when your goals of care shift.

Either the patient or a healthcare agent acting under the patient’s authority can revoke a POLST at any time. The revocation can be verbal in an emergency. The form can also be physically destroyed.

Updating involves signing a new form. Old forms should be destroyed or clearly marked void to prevent confusion.
