15.2 Palliative Care & Hospice Principles in Mobile Integrated Health

15.2 Palliative Care & Hospice Principles in Mobile Integrated Health

Quick Summary: Mobile Integrated Healthcare-Community Paramedicine (MIH-CP) bridges emergency medical systems and specialized end-of-life care. Certified Community Paramedics must differentiate Palliative Care (concurrent symptom management at any stage of chronic illness) from Hospice Care (comfort care for terminal prognoses <= 6 months with curative therapy waived), master protocolized home symptom management for acute crises (dyspnea, pain crises, intractable emesis, terminal secretions, delirium), and conduct dignified, protocol-driven home death verification that avoids non-beneficial emergency transport.

Traditionally, the emergency medical services (EMS) system was structured around a single imperative: rapid resuscitation and emergency department transportation. For patients living with advanced, life-limiting illnesses, this paradigm frequently results in traumatic, unwanted hospitalizations that fragment care and violate patient goals. The Community Paramedic reimagines this response by bringing advanced palliative clinical assessment, symptom relief, and interdisciplinary collaboration directly into the home.

Palliative Care vs. Hospice Care: Regulatory & Clinical Distinctions

Although both disciplines prioritize relief from suffering, quality of life, and holistic patient-family support, they possess critical regulatory, clinical, and administrative distinctions under Medicare and private insurance frameworks.

Palliative Care

• Core Definition: Specialized medical care for individuals living with a serious illness, focused on providing relief from symptoms, pain, and physical/mental stress, irrespective of the diagnosis.
• Concurrent Therapy: Palliative care is delivered concurrently with curative, disease-directed, or life-prolonging interventions. A patient receiving palliative care may simultaneously receive high-dose chemotherapy, experimental clinical trials, radiation, surgical revascularization, hemodialysis, or mechanical circulatory support (e.g., Left Ventricular Assist Device [LVAD]).
• Eligibility & Timeline: No prognostic limitations exist. Palliative care can be instituted at the moment of diagnosis and maintained for years.
• Financing: Billed through standard fee-for-service outpatient physician visits (e.g., Medicare Part B) with standard co-payments.

Hospice Care

• Core Definition: A comprehensive, specialized delivery model of palliative care tailored specifically for patients entering the final phases of a terminal illness.
• Prognostic Requirement: Under the Medicare Hospice Benefit (Title XVIII of the Social Security Act), two physicians (the patient's attending physician and the hospice medical director) must certify that the patient has a life expectancy of 6 months or less if the disease runs its natural course.
• Curative Care Waiver: To enroll in hospice, the patient or legal surrogate voluntarily waives Medicare Part A coverage for curative, disease-directed therapies related to the terminal diagnosis. Comfort becomes the exclusive goal.
• Interdisciplinary Team (IDT): Hospice mandates a four-part team comprising a physician, registered nurse case manager, social worker, and pastoral/spiritual counselor, supplemented by certified nursing assistants (CNAs) and bereavement specialists.
• Financing: Covered 100% by the Medicare Hospice Benefit (Part A), which covers all medications, durable medical equipment (DME), oxygen, and clinical visits directly related to the terminal condition without patient out-of-pocket costs.

1. Dyspnea and 'Air Hunger'

Dyspnea is among the most terrifying symptoms experienced by patients with end-stage COPD, heart failure, and lung malignancies. It represents a neurochemical mismatch between the brainstem respiratory center's demand to breathe and the mechanical capacity of the lungs and chest wall.

• Low-Dose Opioids (The Gold Standard): Opioids are the first-line pharmacotherapy for palliative dyspnea. Morphine blunts the brainstem's perception of air hunger, reduces respiratory work, and relieves anxiety. In an opioid-naive patient, liquid oral or sublingual morphine (2.5 mg to 5 mg PO/SL) provides profound relief within 15 to 20 minutes. In opioid-tolerant patients, a rescue dose equivalent to 10% to 15% of the total 24-hour baseline opioid requirement should be administered. Palliative doses do not cause respiratory depression or hasten death when properly titrated.
• Cool Fan Therapy (Trigeminal Mechanoreceptor Stimulation): Directing a gentle stream of cool air from a portable fan across the patient's nose, cheeks, and mouth stimulates mechanoreceptors in the ophthalmic (V1) and maxillary (V2) branches of the trigeminal nerve. This sensory input reflexively reduces central breathlessness perception, frequently matching the efficacy of supplemental oxygen without drying the mucous membranes.
• Selective Oxygen Utilization: Supplemental oxygen is indicated only if the patient is hypoxemic (SpO2 < 90%). Multiple randomized controlled trials have demonstrated that supplemental oxygen offers zero symptomatic benefit over room air delivered via fan in non-hypoxemic patients.
• Positioning: Upright sitting (high Fowler's) or forward-leaning tripod positioning lowers the diaphragm and maximizes accessory muscle efficiency.

2. Terminal Respiratory Secretions ('The Death Rattle')

During the active dying phase (typically 12 to 48 hours prior to death), moribund patients lose the pharyngeal muscle tone and motor reflexes required to cough or swallow oral secretions. Saliva and bronchial mucus oscillate against the vocal cords during tidal respiration, generating a loud, crackling sound known colloquially as the "death rattle."

• Patient Perception vs. Family Distress: Clinical studies confirm that the unconscious, comatose patient does not experience distress, choking, or asphyxiation from these secretions. However, family members find the noise intensely distressing, interpreting it as active suffocation.
• First-Line Intervention — Gentle Postural Repositioning: Turn the patient onto their side (lateral decubitus or semi-prone) with the head slightly elevated. This allows gravity to drain pooled secretions into the buccal space where they can be wiped with a soft cloth, immediately clearing the airway sound.
• Pharmacotherapy — Anticholinergic Secretion Reducers:
  • Glycopyrrolate (Robinul) 0.2 mg to 0.4 mg SC, IV, or SL: The preferred agent. Glycopyrrolate is a synthetic quaternary ammonium compound that does not cross the blood-brain barrier. Consequently, it prevents excessive salivation without penetrating the central nervous system, avoiding drug-induced delirium, hallucinations, or excessive sedation.
  • Scopolamine (Transdermal patch 1.5 mg or 0.2–0.4 mg SC): Effective, but scopolamine is a tertiary amine that readily crosses the blood-brain barrier, carrying a significant risk of inducing central anticholinergic delirium, nocturnal hallucinations, and paradoxically worsening terminal agitation.
  • Atropine (Ophthalmic 1% drops administered sublingually, 1–2 drops): Rapid sublingual absorption when parenteral routes are unavailable.
• CRITICAL CONTRAINDICATION: Prohibiting Deep Suctioning: Paramedics must never perform aggressive deep pharyngeal or tracheal suctioning in a dying patient. Rigid catheters (Yankauer) or flexible suction tubes cause severe mucosal trauma, induce violent coughing spasms, trigger laryngospasm, stimulate bleeding, and accelerate reactive secretion production while causing terror in nearby family members. Suctioning is restricted to gentle clearing of the anterior oral cavity.

3. Pain Crises & The Hospice Emergency Kit ('E-Kit')

Most hospice patients have a sealed Emergency Comfort Kit (E-Kit) kept in the refrigerator or bedside cabinet containing pre-ordered medications:

• Immediate-Release Opioids: Concentrated oral liquid morphine (20 mg/mL [Roxanol]), oxycodone, or hydromorphone (Dilaudid).
• Protocolized Titration: Community Paramedics working under delegated hospice protocols assess pain using validated non-verbal scales (e.g., PAINAD scale for dementia) and administer ordered sublingual doses. The typical rescue dose is 10% to 20% of the total 24-hour baseline opioid dose, repeated every 30 to 60 minutes until pain relief is achieved.

4. Intractable Nausea and Vomiting

Palliative emesis stems from multiple distinct pathways:

• Chemoreceptor Trigger Zone (CTZ) Stimulation: Triggered by opioids, hypercalcemia, or renal failure. Treated with dopamine antagonists: Haloperidol 0.5 mg to 2 mg SC or SL (highly effective, low anticholinergic sedation).
• Gastric Stasis / Hypomotility: Treated with prokinetics like Metoclopramide 10 mg SC or IV (contraindicated if complete mechanical bowel obstruction is present).
• Vestibular & Serotonergic Pathways: Ondansetron (Zofran) 4 mg to 8 mg ODT, SC, or IV; Promethazine 12.5 mg PR.

5. Terminal Restlessness, Delirium, and Agitation

Terminal delirium presents as acute cognitive fluctuation, hallucinations, thrashing, and attempting to climb out of bed.

• Screening for Reversible Etiologies: Before administering heavy sedation, clinicians must evaluate for acute, treatable discomforts:
  • Urinary Retention: Palpate the suprapubic area. A massively distended bladder is the single most common cause of sudden severe terminal thrashing. Gentle Foley catheterization often produces immediate tranquility.
  • Fecal Impaction: Severe rectal distension from chronic opioid-induced constipation.
  • Uncontrolled Physical Pain or Hypoxia.
• Pharmacological Calming: If delirium persists in the absence of reversible causes, Haloperidol 0.5 mg to 2 mg SC/SL is the drug of choice for perceptual disturbances. If muscle tension, seizure activity, or intense terminal anxiety accompanies delirium, low-dose Lorazepam (Ativan) 0.5 mg to 1 mg SL or SC is added.

Protocol for Expected Deaths in the Home

One of the most profound responsibilities of the Community Paramedic is supporting an expected home death. When a terminal patient expires peacefully at home, calling 911 often triggers an unintended cascade of sirens, police cruisers, and firefighters, turning a solemn passing into an invasive emergency scene.

Clinical Examination & Death Verification

Where permitted by state emergency medical practice acts and local medical direction protocols, Community Paramedics have the legal authority to verify cessation of life and pronounce death in expected home deaths. The verification assessment requires:

1. Auscultation of Apical Heart Sounds: Complete auscultation over the precordium for a minimum of 60 continuous seconds confirming absence of mechanical cardiac activity.
2. Auscultation of Spontaneous Respirations: Continuous auscultation over both lung fields for a minimum of 60 continuous seconds confirming absence of ventilatory effort.
3. Pupillary Examination: Verification of bilaterally fixed, dilated, non-reactive pupils.
4. Neuromuscular Reflexes: Verification of absent corneal reflexes and lack of motor or verbal response to noxious stimuli.

Post-Mortem Care and Interagency Hand-off

• Hospice Notification: Immediately call the on-call hospice triage nurse. The hospice agency will contact the designated mortuary or funeral home and notify the attending physician who signs the official death certificate.
• Preventing Law Enforcement Involvement: In expected hospice deaths, notifying 911 dispatch or local police departments is counterproductive and often traumatizing to families, as officers may treat the domicile as an active crime scene. Law enforcement notification is restricted to unattended, unexpected, violent, or suspicious deaths.
• Medical Device Management: If the death is an expected hospice death and no autopsy or medical examiner investigation is required, gently remove external devices (pulse oximeter, non-invasive oxygen cannula, blood pressure cuff) and elevate the head on a pillow to prevent post-mortem venous facial pooling. However, if any medical examiner jurisdiction applies, leave all lines, catheters, and tubes in situ.

Step-by-Step Worked Clinical Scenario

Setting: A Community Paramedic is dispatched to the home of a 69-year-old female enrolled in hospice with end-stage metastatic ovarian cancer. Her spouse called dispatch in tears stating: "She is suffocating! Her chest is rattling, she is thrashing around, and she can't breathe! Please hurry!"

Scene Arrival & Assessment

The paramedic arrives in an unmarked community response SUV (no lights or sirens), steps into the bedroom, and observes the patient lying supine in a hospital bed. She is deeply comatose, exhibiting Cheyne-Stokes respirations with a loud, bubbling pharyngeal rattling sound on expiration. Her arms are occasionally jerking, and she appears restless with a furrowed brow. Vital signs: SpO2 93% on room air, heart rate 104 regular, respirations 22/min irregular.

Step-by-Step Clinical Execution

1. De-escalate and Educate the Spouse: The paramedic sits beside the husband, places a hand on his shoulder, and speaks in a low, calming tone: "John, Mary is in the active dying phase. That rattling sound sounds awful to hear, but Mary is completely unconscious and not suffocating. Her throat muscles are relaxed, and normal saliva is moving back and forth with her breath. She is not in pain, but we can make her more comfortable and quiet that sound right now."
2. Repositioning (Immediate Mechanical Drainage): The paramedic and husband gently turn Mary onto her right side into a lateral recovery position, placing a soft pillow between her knees and elevating her head 30 degrees. Within two minutes of turning, saliva pools in her cheek; the paramedic gently wipes it away with a soft oral swab. The rattling noise decreases by 75% immediately.
3. Pharmacotherapy for Secretions: The paramedic accesses the bedside Hospice Emergency Kit and locates ordered Glycopyrrolate (Robinul). The paramedic administers 0.2 mg subcutaneously into the upper arm to inhibit new salivary and bronchial glandular production, explaining to the husband that glycopyrrolate does not enter Mary's brain, avoiding confusion.
4. Assess for Reversible Delirium / Agitation: The paramedic inspects Mary's abdomen and palpates a firm, globular mass rising 8 cm above the pubic symphysis, confirming acute urinary retention. The paramedic lubricates and gently inserts a 14-French Foley catheter, immediately draining 850 mL of concentrated urine. Mary's furrowed brow relaxes, and her thrashing ceases entirely.
5. Palliative Comfort Dose: To ensure complete freedom from air hunger and anxiety, the paramedic administers 5 mg (0.25 mL) of concentrated sublingual liquid morphine from the comfort kit onto the buccal mucosa.
6. Coordination with Hospice: The paramedic calls the on-call hospice RN, provides a thorough SBAR report (urinary retention resolved, glycopyrrolate and morphine administered, patient resting peacefully in lateral position with minimal secretions), and remains at the bedside for 45 minutes until the hospice nurse arrives.

Common Exam Traps & Avoidance Strategies

1. Selecting Suctioning for 'Death Rattle': Never choose deep endotracheal or pharyngeal suctioning on the CP-C exam for terminal secretions. Suctioning is invasive, ineffective for vocal cord oscillations, causes mucosal bleeding, and distresses families. The correct protocol is lateral repositioning, gentle oral hygiene, and anticholinergic medications.
2. Choosing Scopolamine Over Glycopyrrolate in Delirious Patients: Scopolamine crosses the blood-brain barrier and can induce or exacerbate anticholinergic delirium and agitation. Glycopyrrolate is a quaternary amine that does not cross the blood-brain barrier and is the preferred agent.
3. Withholding Morphine for Fear of Respiratory Arrest: Opioids are the standard of care for palliative dyspnea. Low doses relieve the subjective sensation of breathlessness without depressing respiratory drive. Withholding opioids from a suffocating terminal patient out of fear of hastening death is a critical clinical error.
4. Routinely Applying Oxygen to Non-Hypoxemic Dyspneic Patients: If SpO2 is >= 90%, supplemental oxygen has no proven benefit over a simple room air fan directed at the face. Exam questions often test the utility of fan therapy stimulating the trigeminal nerve.
5. Transporting Hospice Patients to the ED Without Calling Hospice: If a symptom flare occurs in an enrolled hospice patient, the Community Paramedic must always manage the crisis in place and contact the hospice team. Transporting the patient via 911 to an acute ED revokes or disrupts hospice care and violates patient goals.
