15.1 Advance Directives, DNR Orders & POLST/MOLST Navigation

15.1 Advance Directives, DNR Orders & POLST/MOLST Navigation

Quick Summary: In mobile integrated healthcare and community paramedicine, clinicians frequently encounter complex end-of-life decisions in residential settings. Domain 6 (Ethical and Legal Considerations) requires certified community paramedics to distinguish advisory legal instruments (Living Wills, Durable Power of Attorney for Healthcare) from actionable medical orders (Out-of-Hospital DNR, POLST/MOLST/MOST), deconstruct multi-tiered treatment orders, resolve acute bedside family disputes with de-escalation and medical direction, and navigate the statutory hierarchy of surrogate decision-makers.

End-of-life care planning has evolved from static, broad legal declarations into portable, highly granular medical orders. Community Paramedics operate in an environment without immediate on-site physician presence, requiring profound mastery of the legal boundaries, clinical interpretations, and conflict-resolution strategies surrounding advance care planning. Respecting patient autonomy while navigating high-stakes emotional distress at the bedside is a core competency for advanced community practice.

Legal Advance Planning Instruments: Foundational Distinctions

Advance care planning encompasses two broad classes of documents: Advance Directives (legal declarations of values and appointed decision-makers) and Actionable Medical Orders (clinician-signed direct medical orders). Conflating these two distinct classes represents a major source of medical error and ethical failure in prehospital and community medicine.

Living Wills

A Living Will is a legal document executed by a competent individual outlining their desires regarding life-sustaining medical treatments in the event they develop a terminal illness, end-stage condition, or persistent vegetative state.

• Limitations in the Field: A Living Will is not an actionable medical order for emergency clinicians. Paramedics cannot interpret vague clauses such as "heroic measures," "extraordinary life support," or "reasonable hope of recovery" during an acute crisis.
• Clinical Action: If a patient presents in acute arrest with only a living will and no signed DNR or POLST order, standard emergency medical protocols dictate initiating resuscitation while seeking immediate consultation with Online Medical Direction (OLMD).

Durable Power of Attorney for Healthcare (DPOA-HC / Healthcare Proxy)

A Durable Power of Attorney for Healthcare (also known as a Healthcare Proxy, Healthcare Surrogate, or Medical Power of Attorney) is a legally executed instrument designating a specific surrogate decision-maker to make medical decisions on the patient's behalf.

• Trigger Condition: The authority of a DPOA-HC is strictly dormant while the patient retains medical decision-making capacity. It activates only when the patient is clinically determined to lack capacity due to delirium, coma, severe encephalopathy, or dementia.
• Decision-Making Standards: Surrogates are legally and ethically obligated to apply the Substituted Judgment Standard (making the decision the patient would have made based on known values and prior statements). Only if the patient's wishes are unknown does the surrogate revert to the Best Interests Standard (weighing clinical burdens against benefits).

Out-of-Hospital Do Not Resuscitate (OOH-DNR) Orders

An Out-of-Hospital DNR order is a state-regulated, clinician-signed order directing prehospital and mobile medical personnel to withhold cardiopulmonary resuscitation in the event of cardiac or respiratory arrest.

• Narrow Scope: A DNR order governs only one clinical state: cardiopulmonary arrest (the absence of a palpable pulse and spontaneous respirations).
• The Golden Rule: DNR Does Not Mean 'Do Not Treat': A DNR order has zero application to a living patient with a pulse, regardless of how unstable or critical they appear. A DNR patient experiencing severe asthma, acute pulmonary edema, anaphylaxis, diabetic ketoacidosis, or trauma must receive full, aggressive medical stabilization appropriate to their condition unless a broader order (such as a POLST) limits specific interventions.
• Verification Requirements: Clinicians must verify: (1) Patient full legal name matching clinical identification, (2) Signature and license number of an authorized healthcare provider (MD, DO, or in many jurisdictions, NP or PA), (3) Signature of the patient or designated surrogate, and (4) Effective dates (some state DNR orders require annual renewal or remain valid indefinitely until revoked).

POLST/MOLST Navigation & Deconstruction

The Physician Orders for Life-Sustaining Treatment (POLST) program (known in various jurisdictions as MOLST [Medical Orders for Life-Sustaining Treatment], MOST [Medical Orders for Scope of Treatment], or POST [Physician Orders for Scope of Treatment]) was developed to bridge the dangerous gap between general advance directives and immediate medical orders.

Portability and Legal Standing

Unlike localized hospital DNR orders that expire upon discharge, a POLST is a statutorily protected, legally portable medical order that transfers seamlessly across all care continuum boundaries: private residences, ambulances, emergency departments, intensive care units, and skilled nursing facilities. It does not require re-validation upon transfer between jurisdictions or healthcare institutions.

Section A: Cardiopulmonary Resuscitation (CPR)

• Applies strictly when the patient is pulseless and apneic.
• Options: Attempt Resuscitation / CPR or Do Not Attempt Resuscitation (DNR / Allow Natural Death).
• If "Attempt Resuscitation" is checked, the team initiates chest compressions, defibrillation, advanced airway placement, and intravenous/intraosseous vasopressors.
• If "DNR" is checked, resuscitation is withheld, and care transitions to post-mortem and bereavement protocols.

Section B: Medical Interventions for a Patient with a Pulse

Section B dictates the depth of care when the patient is alive but acutely decompensating. It is broken into three ascending tiers:

1. Comfort-Focused Treatment:
   • Goal: Maximize comfort, relieve pain, ease dyspnea, and promote dignity while allowing natural dying.
   • Permitted Interventions: Medication administration for symptom relief (sublingual morphine, anticholinergics, antiemetics), positioning, oral hygiene, gentle non-invasive suctioning, and low-flow oxygen for comfort.
   • Prohibited Interventions: Invasive intubation, non-invasive positive pressure ventilation (CPAP/BiPAP), cardioversion, continuous cardiac monitoring, and transfer to an acute hospital unless comfort cannot be managed in the residential environment.
2. Selective / Limited Additional Treatment:
   • Goal: Treat reversible medical conditions while avoiding aggressive, prolonged invasive life support.
   • Permitted Interventions: Everything in Comfort-Focused care, PLUS intravenous access, short-term IV fluids (hydration/maintenance), intravenous antibiotics for systemic infection, non-invasive positive pressure ventilation (CPAP or BiPAP) for acute respiratory failure, and non-invasive diagnostic cardiac monitoring. Transfer to an emergency department is appropriate if the patient's acute illness exceeds home stabilization capabilities.
   • Prohibited Interventions: Endotracheal intubation, invasive mechanical ventilation, and long-term intensive care unit (ICU) support.
3. Full Treatment:
   • Goal: Prolong life through all available medical modalities.
   • Permitted Interventions: All comfort and selective measures, PLUS endotracheal intubation, continuous mechanical ventilation, invasive arterial line monitoring, synchronized cardioversion/defibrillation for perfusing dysrhythmias, central venous access, and systemic vasopressor/inotrope infusions with immediate ICU transfer.

[!IMPORTANT] Common Clinical Permutation: Section A DNR + Section B Full Treatment: A patient may legitimately select "DNR" in Section A and "Full Treatment" in Section B. This means the patient desires aggressive, maximal invasive medical therapy (including endotracheal intubation and mechanical ventilation for acute respiratory failure, sepsis, or pulmonary edema) right up until the moment cardiac arrest occurs. If their heart stops, CPR and chest compressions are withheld. Community Paramedics must never assume a DNR order precludes intubation or ICU transfer unless Section B specifically restricts those interventions.

Section C: Artificially Administered Nutrition

Section C guides decisions regarding enteral and parenteral nutrition:

• No Artificial Nutrition by Tube: Oral feeding and hydration offered strictly to the extent tolerated by the patient for pleasure and comfort.
• Defined Trial Period: Short-term nasogastric (NG) tube or percutaneous endoscopic gastrostomy (PEG) with a clear milestone date to assess recovery and reassess goals.
• Long-Term Artificial Nutrition: Permanent enteral or total parenteral nutrition (TPN).

Bedside Conflict Resolution: The Distraught Family Member

One of the most ethically challenging encounters in community paramedicine occurs when an acute crisis strikes a patient with a valid DNR or POLST order, and a panicking, grieving family member demands that the clinician "do everything" and initiate cardiopulmonary resuscitation.

└─────────────────────────────────────────────────────────────────────────┘

The Legal and Ethical Foundation

A competent individual possesses a fundamental, constitutionally protected common-law and statutory right to refuse unwanted bodily invasion and medical treatment. When a patient signs an advance directive or POLST while competent, that document represents their direct voice. A family member—even a legally designated DPOA-HC—has zero legal authority to revoke or override a patient's valid autonomous directive unless the patient is currently competent and verbally requests the revocation, or the legal proxy can present documented evidence that the patient revoked the order prior to losing capacity.

Clinical Communication & De-escalation Strategy

When confronted with high emotional volatility, clinicians must avoid defensive hostility and employ structured palliative communication:

1. Acknowledge and Empathize: Apply the NURSE mnemonic (Name the emotion, Understand, Respect, Support, Explore). Example: "I can see how terrified and heartbroken you are right now. You love your father and want to save him."
2. Align with the Patient's Expressed Goals: Separate the clinical decision from the paramedic and place it squarely on the patient's own agency: "Your father sat down with his physician specifically to complete this document because he wanted to spare his body the trauma of chest compressions and electric shocks when his heart gave out. Our duty right now is to honor his explicit wish to die peacefully at home."
3. Provide Active Care Instead of Inaction: Family panic often stems from the perception of abandonment. Clinicians must actively perform comforting interventions: suction secretions gently, administer sublingual medications for air hunger, dim harsh lights, elevate the head of the bed, and encourage family to hold the patient's hand.
4. Consult Online Medical Direction (OLMD): If the family remains aggressive or threatens violence, contact OLMD immediately. Physicians are trained to speak directly with family members via speakerphone to validate grief, confirm the legal validity of the POLST, and shoulder the medical-legal responsibility for withholding invasive care.
5. Absolute Prohibition of 'Slow Codes': Performing a "slow code" (initiating token, substandard chest compressions or delayed defibrillation to provide theatrical comfort to family) is universally condemned by the American College of Emergency Physicians (ACEP), the National Association of EMS Physicians (NAEMSP), and bioethicists. Slow codes are fraudulent, deceptive, violate patient autonomy, degrade clinical integrity, and carry severe civil liability.

Statutory Hierarchy of Surrogate Decision-Makers

When an adult patient loses medical decision-making capacity and has not executed a valid Durable Power of Attorney for Healthcare, clinicians must turn to state statutory surrogate consent laws. While slight variations exist across state codes, the universal legal hierarchy proceeds in the following mandatory descending order:

STATUTORY SURROGATE DECISION-MAKER HIERARCHY
[1. Court-Appointed Legal Guardian (with healthcare authority)]
      │ (If none exists)
      ▼
[2. Designated DPOA-HC / Healthcare Proxy / Agent]
      │ (If none designated or unavailable)
      ▼
[3. Legal Spouse or State-Recognized Domestic Partner]
      │ (If none, divorced, or unavailable)
      ▼
[4. Adult Children (Majority consensus among all available children)]
      │ (If none or unavailable)
      ▼
[5. Parents of the Adult Patient]
      │ (If deceased or unavailable)
      ▼
[6. Adult Siblings (Majority consensus)]
      │ (If none or unavailable)
      ▼
[7. Nearest Adult Relative / Designated Close Friend (Statute-dependent)]

Critical Rules Governing Surrogates

• Equality Within Tiers: When multiple individuals occupy the same tier (e.g., three adult children), state laws generally require a majority consensus. If two adult children demand a palliative approach while one demands aggressive intervention and no consensus can be reached, the Community Paramedic must immediately involve Online Medical Direction and institutional risk management/ethics committees.
• Disqualification of Estranged or Interested Parties: An individual who has a documented history of domestic abuse against the patient, or who is currently facing protective orders, is legally disqualified from acting as a surrogate.

Step-by-Step Worked Clinical Scenario

Setting: A Community Paramedic is dispatched to a residential home for an 81-year-old male with end-stage ischemic cardiomyopathy (ejection fraction 15%) and severe chronic obstructive pulmonary disease (COPD). The patient's home health aide called 911 due to acute dyspnea, somnolence, and diaphoresis. Upon arrival, the patient is semi-conscious, tachypneic at 36 breaths/min with audible expiratory wheezing, heart rate 118 sinus tachycardia, blood pressure 102/64 mmHg, and SpO2 81% on room air.

Document Discovery & Verification

The patient's daughter hands the paramedic a brightly colored, valid POLST form dated four months prior, signed by the patient and his cardiologist. The paramedic reviews the sections:

• Section A: Do Not Attempt Resuscitation (DNR / Allow Natural Death).
• Section B: Selective / Limited Additional Treatment. The form explicitly notes: "Non-invasive positive pressure ventilation (CPAP/BiPAP) permitted. IV access, IV steroids, and bronchodilators permitted. NO endotracheal intubation or mechanical ventilation."
• Section C: No artificial nutrition by tube.

The Bedside Crisis

The patient's son arrives from out of town, bursts into the room in a state of panic, and screams: "You have to intubate him right now! Put him on the machine and get him to the hospital! I am his son and I demand you save his life!"

Clinical and Operational Execution

1. Establish Decision-Making Capacity: The paramedic rapidly confirms the patient has acute hypercapnic encephalopathy, is somnolent, oriented only to person, and currently lacks medical decision-making capacity.
2. De-escalate the Son: The paramedic looks the son in the eye and calmly states: "Sir, I can see how terrifying this is for you. We are not letting your father suffer. We are actively treating his breathing crisis right now, but your father signed this medical order with his cardiologist stating clearly that he never wanted a breathing tube placed down his throat. He chose non-invasive breathing masks and medications instead. We are honoring his exact instructions."
3. Initiate Permitted Selective Interventions (Section B):
   • Apply high-flow nasal cannula or non-invasive positive pressure ventilation (CPAP) at 8 cm H2O with supplemental oxygen titrated to maintain SpO2 88% to 92%.
   • Establish intravenous access.
   • Administer nebulized albuterol (2.5 mg) and ipratropium (0.5 mg) via in-line CPAP circuit.
   • Administer methylprednisolone 125 mg IV.
   • Administer 2.5 mg sublingual liquid morphine to relieve central air hunger and blunt respiratory drive panic.
4. Consult Online Medical Direction: While the interventions take effect, the paramedic contacts OLMD, confirms the valid POLST Section B orders, describes the son's objection, and places the medical director on speakerphone with the son. The physician reinforces that intubation is clinically and legally contraindicated by the patient's valid order.
5. Outcome: Within 20 minutes on CPAP and bronchodilators, the patient's respiratory rate decreases to 20 breaths/min, accessory muscle use diminishes, and SpO2 stabilizes at 91%. The son visibly relaxes, expressing gratitude that his father is breathing comfortably without invasive tubes. The paramedic coordinates an urgent home visit by the mobile integrated health team and the primary palliative care physician.

Common Exam Traps & Avoidance Strategies

1. Equating a Living Will with an Actionable Medical Order: Living wills are aspirational legal declarations that cannot be directly executed in the field by emergency clinicians. If a pulseless patient has only a Living Will and no DNR/POLST, CPR must be initiated while contacting OLMD.
2. Assuming DNR Means 'Do Not Treat' in a Perfusing Patient: Never withhold active treatment for reversible conditions (e.g., anaphylaxis, asthma, hypoglycemia, congestive heart failure) in a living patient simply because they have a DNR order. DNR activates only when the patient has no pulse and is not breathing.
3. Yielding to Family Demands to Violate a Valid POLST: Family members cannot unilaterally cancel or override a competent patient's prior autonomous medical directive. Yielding to a demanding relative by initiating unwanted intubation or CPR constitutes medical battery and a violation of civil rights.
4. Performing 'Slow Codes' for Theatrical Purposes: Slow codes are fraudulent, unethical, and legally indefensible. Never select an answer choice that advocates performing half-hearted chest compressions or delayed pacing to placate family members.
5. Surrogate Overreach During Patient Competence: A Healthcare Proxy has zero decision-making authority while the patient remains conscious and possesses decision-making capacity. Always take direction directly from the competent patient.
