What are the evidence‑based palliative care guidelines for establishing goals of care, involving a multidisciplinary team, and managing symptoms such as pain, neuropathic pain, dyspnea, nausea, vomiting, and delirium?

Palliative Care Guidelines: Evidence-Based Approach

Establish goals of care early through structured advance care planning with skilled facilitators, involve interdisciplinary teams including palliative care specialists for complex cases, and manage symptoms using opioids for pain and dyspnea, gabapentin for neuropathic pain, dopaminergic agents for nausea/vomiting, and haloperidol for delirium. 1

Goals of Care and Advance Care Planning

All patients with serious illness require advance care planning that addresses surrogate decision makers, resuscitation preferences, and emergency treatment as early as possible in the disease course 1. This planning must:

• Involve skilled facilitators (palliative care providers, trained nurses, or social workers)
• Include key decision makers (patients, caregivers, family)
• Address care across all settings (hospital, home, hospice)
• Be reassessed when significant clinical changes occur 1

Schedule longer appointment times to establish and clarify goals of care at a health literacy level appropriate for the patient and support system 2. The primary care provider must maintain communication through end of life to prevent patient abandonment 2.

Multidisciplinary Team Integration

Medical providers must develop and participate in interdisciplinary teams, with mandatory consultation of palliative care specialists for pain management, nonpain symptoms, and goals of care discussions 2. The team should include:

• Palliative care physicians or advanced practice providers
• Nursing staff
• Social workers
• Chaplains/spiritual care providers
• Physical and occupational therapists
• Primary care physicians 2, 3

Engage in frequent communication between the multidisciplinary team, patient, and patient's support system 2. Make timely referrals for palliative or hospice care when patients have advanced illness requiring support beyond the clinic 2.

Pain Management

Assessment

Conduct periodic pain assessment using validated tools: Numeric Rating Scale (NRS), Visual Analog Scale (VAS), or Verbal Rating Scale (VRS) for communicative patients 4. For non-communicative patients, use observational scales like the Behavioral Pain Scale (BPS) or Critical Care Pain Observation Tool (CCPOT) 5, 4.

Investigate any new pain report carefully in patients with controlled chronic pain—this may require treatment adjustments or added medications while evaluating the new problem 2.

Treatment Algorithm

First-line: IV opioids (morphine, fentanyl, or hydromorphone) titrated to pain intensity endpoints 5, 1, 6. All IV opioids are equally effective when properly titrated 5, 6.

Add nonopioid analgesics to decrease opioid requirements and side effects:

• IV or oral acetaminophen
• NSAIDs (for cancer pain specifically) 1
• Bisphosphonates for bone pain in breast cancer and myeloma 1

Prescribe bowel regimen (senna or lactulose) immediately when initiating sustained opioid dosing, unless contraindicated by bowel obstruction or diarrhea 6. Constipation is the most persistent opioid side effect.

Neuropathic Pain Management

Start gabapentin as first-line oral pharmacological treatment, titrating to 2400 mg per day in divided doses 2. Gabapentin also improves sleep scores 2.

If inadequate response to gabapentin, trial serotonin-norepinephrine reuptake inhibitors (SNRIs) or tricyclic antidepressants 2.

Consider hypnosis as an adjunctive therapy for neuropathic pain 2.

Dyspnea Management

Administer opioids for severe and unrelieved dyspnea in cancer and cardiopulmonary disease at end of life 1. Start with low-dose fast-acting opioid (e.g., fentanyl), observe for response, and titrate upward if respiratory distress persists 6.

Provide oxygen for short-term relief of hypoxemia in advanced COPD 1.

Nausea and Vomiting Management

First-line: Dopaminergic pathway antagonists

• Haloperidol 0.5-2 mg IV/PO every 6-8 hours
• Metoclopramide
• Prochlorperazine 5-10 mg IV or 25-50 mg PO every 6-8 hours 4

For bowel obstruction caused by cancer: Add octreotide 4.

If first-line agents fail: Add ondansetron (5-HT3 antagonist) as second agent 4.

Consider adding:

• Dexamethasone 2-8 mg for bowel obstruction or intracranial hypertension
• Lorazepam 0.5-2 mg for anticipatory nausea 4

Delirium Management

Use haloperidol as the primary agent for delirium management 4. Avoid neuromuscular blockers during withdrawal of life support as they prevent pain assessment 7.

Multimodal analgesia is mandatory in patients not suitable for further interventions to control pain and related symptoms including agitation and delirium 4.

Non-Pharmacological Interventions

Implement cognitive behavioral therapy (CBT) for chronic pain management—it promotes adaptive behaviors and addresses maladaptive ones 2.

Recommend yoga for chronic neck/back pain, headache, rheumatoid arthritis, and musculoskeletal pain 2.

Prescribe physical and occupational therapy for chronic pain 2.

Depression Management

Treat depression with tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs), or psychosocial interventions in patients with cancer 1. Regularly assess for depression as part of routine symptom screening 1.

Common Pitfalls

• Failing to prescribe bowel regimen with opioids: This is the most common persistent side effect and must be addressed prophylactically 6
• Delaying palliative care consultation: Consultation should occur early for complex pain, uncontrolled symptoms, or goals of care discussions 2
• Using only patient self-report in non-communicative patients: Must use validated observational scales 5, 4
• Inadequate reassessment: Conduct regular intervals after each therapy change has had adequate time to take effect 2
• Withholding high-dose opioids/sedatives due to hastening death concerns: Guidelines endorse their use for pain control regardless of this risk 7
