Physician/Portable Orders for Life-Sustaining Treatment — an actionable medical order for the seriously ill and frail, distinct from an advance directive
The POLST paradigm (Physician/Portable Orders for Life-Sustaining Treatment) was built on a simple but consequential idea: not every adult needs a signed medical order about resuscitation and life-sustaining treatment, but every seriously ill or frail patient benefits from one. Appropriateness screening is the first and most consequential step — completing a POLST for the wrong population dilutes its clinical value and can create confusing, sometimes conflicting, paperwork in a patient's chart.
The POLST paradigm originated in Oregon in 1991, developed by a task force led by Susan Tolle and colleagues at Oregon Health & Science University in response to a persistent clinical problem: patients' documented wishes about resuscitation and aggressive treatment were routinely not honored during transfers between nursing facilities, hospitals, and home, because advance directives are not written as directly actionable medical orders.
The population POLST is designed for is intentionally narrow: patients with serious illness or frailty such that a clinician would not be surprised if the patient died within the next year — the so-called "surprise question." This includes patients with advanced dementia, metastatic or treatment-refractory cancer, end-stage heart, lung, kidney, or liver failure, frailty with recurrent hospitalizations or functional decline, and patients enrolled in or eligible for hospice.
POLST is explicitly not intended for healthy adults, or for patients with stable chronic disease and a normal life expectancy. National POLST guidance is direct on this point: completing a POLST for a low-acuity, stable patient can produce orders (particularly a DNR order) that do not reflect what that patient would actually want if they suffered a sudden, reversible cardiac event unrelated to their baseline condition — precisely the scenario POLST is not meant to address.
Advance directives (living wills and healthcare power-of-attorney documents) and POLST forms are frequently confused, but they are legally and functionally distinct instruments meant to be complementary, not interchangeable.
An advance directive is a statement completed by any competent adult, regardless of current health, addressing hypothetical future scenarios ("if I am ever in a persistent vegetative state..."). It does not, by itself, instruct a clinician to do or not do anything right now — it must be interpreted by a surrogate decision-maker and treating clinician at the moment of a future crisis, often under time pressure, sometimes years after it was written.
A POLST is a standing medical order, signed by a physician, nurse practitioner, or physician assistant, that translates a patient's current goals of care into checkbox orders effective immediately upon signature. It requires no interpretation at the bedside: EMS personnel and hospital staff can act on it directly, the same way they would act on any other physician order in a chart.
A POLST does not replace an advance directive — the two are designed to work together across the trajectory of illness. Every adult, healthy or not, should be encouraged to complete an advance directive naming a healthcare proxy and describing broad values. Only patients who have crossed into serious illness or frailty should additionally complete a POLST, which converts those values into specific, immediately actionable orders for the here and now.

A POLST form is only as good as the conversation behind it. National POLST guidance is explicit that the document should never be handed to a patient as a form to fill out alone, and should never be completed from a chart review without a conversation. The defining feature of a well-run POLST conversation is that it addresses the patient's actual, current clinical situation — not a menu of hypothetical future scenarios.
Because POLST orders take effect immediately, the conversation that produces them must be anchored in the patient's actual diagnosis, trajectory, and realistic near-term possibilities — not abstract hypotheticals like "if your heart ever stopped, at any point in your life." A skilled clinician first assesses what the patient and family already understand about the prognosis, corrects major misunderstandings gently, and then explores what matters most to the patient given that reality: comfort, time at home, avoiding repeated hospitalizations, remaining independent, or pursuing aggressive treatment for a chance at more time.
Accurate information exchange matters enormously. Patients and families who overestimate the likely benefit of CPR (television medical dramas depict survival rates far above reality) often choose differently once given honest statistics: for frail, multimorbid, or seriously ill patients, survival to hospital discharge after in-hospital CPR is commonly in the range of 10–20%, and neurologically intact survival is lower still. For patients with metastatic cancer or advanced dementia, survival to discharge after CPR is frequently in the single digits.
The conversation also surfaces "preparedness planning" — anticipating specific, foreseeable near-term scenarios given the patient's actual disease (an aspiration event in advanced dementia, a COPD exacerbation, a bowel obstruction in ovarian cancer) rather than generic hypotheticals, so that the resulting orders are genuinely responsive to what is likely to happen.
The conversation is typically led by the treating physician, nurse practitioner, or physician assistant, often supported by trained facilitators — palliative care nurses, social workers, or chaplains who have completed POLST-specific communication training. Structured frameworks such as Ask-Tell-Ask (ask what the patient understands, tell needed information in plain language, ask them to reflect it back) and SPIKES (a stepwise protocol for delivering serious news) are widely used to keep the conversation patient-centered rather than form-centered.
If the patient lacks decision-making capacity, the conversation is held with the legally authorized surrogate or healthcare representative, guided by substituted judgment — what would this patient have wanted — rather than what the surrogate personally would choose.
A foundational and legally protected principle across every POLST program is voluntariness: completing a POLST is never mandatory, cannot be required as a condition of admission to a hospital, nursing facility, or hospice, and a patient or surrogate may decline to complete one, or may choose full treatment across every section, without penalty or pressure.
Multiple outcomes studies — including work by Hickman, Tolle, and colleagues in Oregon nursing facilities — have found that patients with POLST forms in place have documented treatment orders that align more closely with their expressed preferences, and are significantly less likely to receive unwanted resuscitation, hospitalization, or intensive interventions, compared with similar patients relying on an advance directive alone.
The National POLST form (the template most state programs adapt) is a single page divided into ordered sections, each translating one dimension of the goals-of-care conversation into a specific, checkable medical order. Internal consistency across sections matters as much as the content of any one box — a well-completed POLST tells one coherent clinical story.
Section A — Cardiopulmonary Resuscitation: applies only if the patient has no pulse and is not breathing. Two options: "Attempt Resuscitation/CPR" or "Do Not Attempt Resuscitation/DNR (Allow Natural Death)." This section is answered first because it frames the rest of the form; if the patient has a pulse or is breathing, Section B governs instead.
Section B — Medical Interventions: describes the desired intensity of treatment if the patient has a pulse and is breathing but is in medical distress. Three standard tiers: Full Treatment (use all appropriate interventions including ICU-level care and intubation), Selective Treatment (medical treatment including antibiotics and IV fluids, but generally avoiding intubation and ICU transfer unless a trial is clearly needed), and Comfort-Focused Treatment (relieve pain and suffering with medication, positioning, and basic care; avoid hospital transfer unless comfort cannot be achieved elsewhere).
Section C — Artificially Administered Nutrition: addresses long-term feeding tubes specifically (not hand-feeding or short-term IV fluids during an acute illness), with options for long-term artificial nutrition, a defined trial period, or no artificial nutrition by tube.
Section D (or an equivalent signature block) — requires the dated signature of the patient (or legally authorized surrogate) and the signature of the physician, nurse practitioner, or physician assistant, whose scope of authority to sign varies by state. Without this signature, the form is not a valid medical order — it is, at most, a worksheet.
Because each section is answered somewhat independently during the conversation, part of finalizing the form is a deliberate internal-consistency check by the signing clinician. Some combinations are perfectly coherent even though they might look contradictory at first glance: a patient can reasonably choose Full Treatment in Section B (wanting aggressive medical management of a reversible problem) while still choosing DNR in Section A (not wanting chest compressions and defibrillation if their heart actually stops) — this combination is common and clinically sound.
Other combinations warrant a second look: choosing Comfort-Focused Treatment in Section B while selecting "Attempt Resuscitation" in Section A is generally internally inconsistent, since comfort-focused care is built around avoiding burdensome, invasive interventions, and CPR is among the most burdensome. A careful clinician revisits the conversation with the patient rather than simply accepting the checkboxes as given.
Most state programs also allow a verbal order to be taken over the phone (for example, when a hospice nurse reaches a physician urgently) provided it is co-signed by the clinician within a defined window, typically 24 to 7 days depending on the state — preserving timeliness without sacrificing the requirement for clinician authorization.
The single feature that most distinguishes POLST from an advance directive is portability: a signed POLST is designed to be recognized and followed the instant it is presented, in any care setting, by any clinician or EMS crew, without a phone call to verify authenticity or interpret intent. This is what "actionable" means in practice.
Legally, a POLST is a physician-signed medical order, occupying the same category as an order for medication or oxygen — something EMS and hospital staff are trained and authorized to act on directly. An advance directive is a statement of the patient's own wishes; EMS protocols in most jurisdictions do not permit paramedics to interpret a multi-page legal document at the roadside or in a living room and decide, on their own authority, to withhold resuscitation based on it.
This distinction has real consequences during emergencies. Multiple studies of nursing facility residents and hospice patients (notably work led by Hickman, Tolle, and colleagues using the Oregon POLST Registry) found that treatment actually delivered was more concordant with POLST orders than with advance directives alone, and that patients with a Comfort-Focused Treatment POLST were far less likely to receive unwanted hospital transfer, intensive procedures, or resuscitation than similar patients without a POLST.
EMS deference protocols formalize this: when a valid, signed POLST is present and visible, EMS is trained to follow it directly — including honoring a DNR/Allow Natural Death order — without requiring online medical control contact, provided the form appears current and unaltered.
A 2010 study by Hickman and colleagues found that POLST orders for limiting treatment were followed with high fidelity across care transitions in Oregon nursing facilities — a level of concordance substantially higher than historical rates of honoring advance directive preferences alone, which frequently required reinterpretation, family debate, or were simply unavailable at the critical moment.
To make a POLST instantly recognizable in a chaotic clinical moment, most state programs print the form on distinctive, brightly colored card-stock — historically bright pink or a similarly saturated hue — so it stands out on a refrigerator door (a common storage location recommended for home use), at the front of a paper chart, or taped to a hospital bed rail. The goal is that any responder can identify "this is a POLST" from across the room, before even reading the content.
Oregon pioneered a statewide electronic POLST registry, launched in the early 2000s, that EMS and emergency departments can query 24/7 by patient identifiers to retrieve the most recent valid form even if the physical document is not present — critical when a patient is found away from home, or the paper copy has been misplaced during a transfer. Many other states (including California, Washington, West Virginia, and others) have since built similar statewide e-registries or are integrating POLST status into health information exchanges.
Portability also means the form must travel physically with the patient across every transition: hospital to skilled nursing facility, nursing facility to home, home to emergency department, and back again. Standard practice is that the original or a copy accompanies the patient at each transfer, and receiving facilities are expected to honor an out-of-facility POLST without requiring it to be re-executed.
A POLST has no fixed expiration date, but it is never meant to be "set and forgotten." Because it is a standing order that will be acted on immediately and literally, national guidance defines clear triggers for review, and a formal process for retiring an outdated form so that exactly one valid POLST exists for a patient at any given time.
National POLST guidance identifies three standard triggers for revisiting a form with the patient or surrogate: a transfer between care settings (hospital admission or discharge, nursing facility placement, enrollment in hospice), a substantial change in health status (a new diagnosis, a major decline in function, an acute event that changes prognosis), and any indication that the patient's treatment preferences themselves have changed, even if health status has not.
Many hospitals and nursing facilities build a POLST review into admission and discharge workflows precisely because transitions are both high-risk moments for miscommunication and natural opportunities to confirm the form still reflects the patient's current wishes. A form completed a year ago by a patient who has since stabilized, or conversely has declined further than anticipated, may no longer represent what that patient wants today.
Review does not always change the orders — many patients reaffirm the same choices — but the act of revisiting the conversation, rather than assuming a prior form remains valid indefinitely, is itself the safeguard.
When a POLST no longer reflects a patient's wishes, standard practice is never to cross out or alter individual checkboxes on the existing form. Instead, the clinician draws a diagonal line across the entire form and writes "VOID" in large letters, then completes an entirely new POLST reflecting the updated conversation. This preserves an unambiguous paper trail and prevents any confusion about which version is authoritative — a partially edited form is exactly the kind of ambiguity POLST was designed to eliminate.
If more than one POLST is somehow present for a patient (for example, one completed in a hospital and an older one still in a nursing facility chart or on the home refrigerator), the standing rule EMS and clinical staff are trained to apply is to follow the most recently signed, valid order, and to treat any earlier version as superseded. Registries help resolve this ambiguity in states where they exist, by returning only the current form on file.
A patient or authorized surrogate retains the right to revoke a POLST at any time, verbally or in writing, and clinicians are expected to honor a clear revocation immediately, pending completion of a new form if appropriate — reinforcing that, like an advance directive, a POLST always remains an expression of the patient's autonomy, not a binding contract that overrides a change of mind.
