POLST vs. Advance Directive in California: What Families Need to Know

In California, an Advance Health Care Directive is a legal document any adult can complete to name a healthcare agent and describe their wishes for future care. A POLST (Physician Orders for Life-Sustaining Treatment) is a medical order, signed by the patient and a doctor, nurse practitioner or physician assistant, for people with serious illness or frailty, telling emergency responders and hospitals what treatments to provide now. Most older adults should have an advance directive; people with serious illness should usually have both.

Families often wait until a crisis to talk about end-of-life wishes, and then face agonizing decisions in a hospital hallway. Having the right documents in place, and knowing where they are, gives your parent control and spares the family from guessing. Understanding a POLST in California and how it differs from an advance health care directive helps families make sure a parent’s wishes are followed.

This guide explains the difference between the two documents, who needs each one, how to complete them in California, and practical tips for keeping them available. It’s general information, not legal or medical advice.

What’s the difference between an advance directive and a POLST?

• What it is
  • Advance Health Care Directive: A legal document
  • POLST: A medical order
• Who completes it
  • Advance Health Care Directive: Any adult 18 or older
  • POLST: Patient (or legal decision-maker) with a doctor, NP or PA
• Who it’s for
  • Advance Health Care Directive: Everyone
  • POLST: People with serious illness or frailty
• What it does
  • Advance Health Care Directive: Names a healthcare agent and records wishes for the future
  • POLST: Directs specific treatments now, such as CPR and intubation
• Followed by EMS?
  • Advance Health Care Directive: Generally not directly in an emergency
  • POLST: Yes, emergency responders follow it
• Form
  • Advance Health Care Directive: Various forms, including the California statutory form
  • POLST: Standardized California POLST form (usually bright pink)
• Witnessing
  • Advance Health Care Directive: Two qualified witnesses or a notary
  • POLST: Signed by patient and clinician

What does an Advance Health Care Directive include?

• Healthcare agent: the person who makes medical decisions if your parent can’t. This is sometimes called a healthcare power of attorney.
• Alternate agents in case the first choice isn’t available
• Treatment wishes, such as preferences about life support, pain relief and comfort care
• Other preferences, such as organ donation and where they’d prefer to receive care

In California, the directive must be signed and either witnessed by two qualified adults or notarized. For residents of skilled nursing facilities, special witnessing rules apply, including a patient advocate or ombudsman.

What does a POLST include?

The California POLST form addresses:

• CPR: attempt resuscitation or allow natural death if the heart stops
• Medical interventions: full treatment, selective treatment, or comfort-focused treatment
• Artificially administered nutrition: such as feeding tubes

A POLST is completed after a conversation between your parent and their clinician about their health and goals. It’s most appropriate when a clinician wouldn’t be surprised if the person died within the next year.

Who needs which document?

• Healthy adult: Advance directive
• Older adult with chronic conditions: Advance directive; discuss POLST with the doctor
• Serious illness, frailty, or advanced dementia: Advance directive and POLST
• Receiving hospice: POLST is commonly completed; keep the advance directive too

How do you help a parent complete these documents?

1. Start the conversation early, ideally while your parent is healthy and has capacity.
2. Talk about values: what matters most, what they fear, what a good day looks like.
3. Choose a healthcare agent who knows your parent’s wishes and can handle pressure.
4. Complete the advance directive, with witnesses or a notary. An elder law attorney can help, and free forms are available.
5. Schedule a visit with the doctor to discuss a POLST if your parent is seriously ill or frail.
6. Share copies with the agent, family, doctors and the local hospital.
7. Review every few years and after major health changes.

For parents with dementia, completing documents in the early stage is critical. See in-home Alzheimer’s care.

Where should you keep these documents?

• POLST: keep the original where emergency responders can find it quickly, commonly on the refrigerator or by the bedside. It should go with your parent to the hospital.
• Advance directive: keep the original in a safe but accessible place (not a locked safe deposit box), with copies for the agent and doctors.
• Registry: California has an advance directive registry through the Secretary of State.
• Home care team: let your parent’s caregivers know where documents are kept.

How do caregivers use these documents?

Non-medical caregivers don’t make medical decisions, but they should know where the POLST is, call 911 in an emergency, and give responders the form. Knowing your parent’s wishes also helps caregivers support comfort and dignity, especially alongside hospice. See 24-hour home care during hospice.

How do you start the conversation about end-of-life wishes?

Many families put off talking about end-of-life care until a crisis forces decisions in a hospital hallway. Starting earlier, when everyone is calm, gives your parent a real voice.

• Pick a calm moment. A quiet afternoon at home works better than a holiday dinner or a hospital room.
• Start with values, not forms. Ask what makes a good day, what they fear most about getting sick, and what they would want if they could not speak for themselves.
• Use a prompt. A news story, a friend’s illness, or your own planning can make the subject feel natural.
• Share your own wishes. It can make the conversation feel less one-sided.
• Take more than one conversation. It is fine to stop and come back to it.

Write down what your parent says in their own words. Those notes help the health care agent and doctor understand the reasons behind the choices, not only the choices themselves.

When should advance directives and POLST forms be reviewed?

These documents are not one-time paperwork. Review them after a new serious diagnosis, a hospital stay, a move to a new care setting, or a change in the person named as health care agent. A yearly review, perhaps around a birthday or annual physical, is a good habit.

Ask your parent whether the documents still reflect their wishes, and update them if not. A POLST in particular should match your parent’s current health and goals, since it guides emergency treatment. Understanding POLST in California helps families make sure the right document is in place when it is needed.

Who should have copies of these documents?

Give copies of the advance directive to the health care agent, any backup agents, and your parent’s doctors. Ask that it be added to your parent’s medical record. Keep the POLST where emergency responders can find it, often on the refrigerator or by the bed, and bring a copy to hospital visits.

Make sure caregivers know where the documents are and who to call. A document no one can find in an emergency cannot do its job.
