What is the best approach for palliative management of an older patient with chronic obstructive pulmonary disease (COPD) experiencing an exacerbation, characterized by increased breathlessness and anxiety, with a potential history of smoking and comorbid conditions such as cardiovascular disease or diabetes?

Palliative Management of COPD Exacerbation with Breathlessness and Anxiety

For patients with COPD exacerbation experiencing breathlessness and anxiety, initiate low-dose oral morphine (2.5-5mg immediate-release every 4 hours) to relieve refractory dyspnea, combined with short-acting bronchodilators, benzodiazepines for severe anxiety, and oxygen therapy only if documented hypoxemia (PaO2 ≤55 mmHg or SaO2 ≤88%), while simultaneously conducting advance care planning discussions about goals of care and preferred place of death. 1, 2, 3, 4

Immediate Symptom Management

Dyspnea Control

• Opioids are the cornerstone for refractory breathlessness in advanced COPD, with morphine being the most studied agent 2, 4, 5
• Start with immediate-release morphine 2.5-5mg orally every 4 hours, titrating based on symptom relief 4, 5
• Critical caveat: While morphine carries FDA warnings about respiratory depression in COPD patients, the evidence supports its use for refractory dyspnea when standard therapies have failed, provided patients are monitored appropriately 3, 4
• Continue short-acting bronchodilators as they remain routinely indicated even in palliative contexts 1, 2

Oxygen Therapy

• Only prescribe long-term oxygen if documented severe hypoxemia (PaO2 ≤55 mmHg or SaO2 ≤88% on room air) 2, 6
• Oxygen does not relieve dyspnea in non-hypoxemic patients and should not be used as a comfort measure without documented hypoxemia 2
• Ensure reliable delivery system (concentrator preferred over cylinders) to prevent dangerous "running out" episodes 6

Anxiety Management

• Benzodiazepines are appropriate for severe anxiety accompanying breathlessness in end-stage COPD 4, 5
• Use lowest effective doses due to respiratory depression risk when combined with opioids 3
• Screen for and treat depression, which is highly prevalent and often unrecognized in advanced COPD 2, 7, 8

Non-Pharmacologic Interventions

Breathing Techniques

• Teach pursed-lip breathing, which reduces respiratory rate and dyspnea while improving oxygen saturation 1
• Encourage forward-leaning positions with arm support (using walker/rollator), which decreases dyspnea and increases exercise capacity 1
• Avoid diaphragmatic breathing techniques, as controlled studies do not support their use in COPD 1

Ventilatory Support Considerations

• Non-invasive ventilation (NIV) can be used to relieve acute dyspnea but should be the last option, as potential benefits must be weighed against adverse effects like respiratory dehydration or worsening dyspnea 1
• NIV should not prolong an already initiated dying process 1

Advance Care Planning (Essential Component)

Timing and Content

• Discuss end-of-life wishes, preferred place of death, and goals of care during this exacerbation, not waiting for future stable periods 1, 2, 6
• The American Thoracic Society and European Respiratory Society emphasize that discussions about death should be a natural part of medical consultation in advanced COPD 1, 2
• Clarify preferences regarding future hospitalization, mechanical ventilation, and resuscitation 6
• Pulmonary rehabilitation settings and acute exacerbations are both appropriate venues for advance care planning discussions 1, 6

Prognostic Indicators Warranting These Discussions

• Frequent hospitalizations (≥2 exacerbations per year) indicate severe disease with high mortality risk 2
• FEV1 ≤20% predicted indicates very severe disease 2
• Chronic hypercapnia (PaCO2 >50 mmHg) signals advanced disease 2
• Unintentional weight loss and poor nutrition are associated with increased mortality 2

Medication Optimization

Exacerbation-Specific Therapy

• Continue systemic corticosteroids and antibiotics as indicated per standard COPD exacerbation guidelines 1
• Maintain inhaled corticosteroids combined with long-acting bronchodilators to reduce future exacerbation frequency 4

Medication Reconciliation

• Simplify regimens and assess inhaler technique, as cognitive impairment may prevent proper use 6
• Consider switching to nebulized medications if inhaler technique cannot be mastered 6

Critical Pitfalls to Avoid

• Do not withhold opioids due to fear of respiratory depression when dyspnea is refractory to standard therapy—the goal is symptom relief, and evidence supports their use 4, 5, 9
• Do not prescribe oxygen without documented hypoxemia, as it provides no benefit and creates unnecessary burden 2, 6
• Do not delay palliative care discussions until the patient is actively dying—these conversations reduce anxiety and ensure care aligns with patient wishes 1, 2, 7
• Do not avoid benzodiazepines entirely due to respiratory concerns when anxiety is severe and contributing to dyspnea, but use lowest effective doses and monitor closely 3, 4
• Do not initiate pulmonary rehabilitation during acute exacerbation in end-stage patients, as it may compromise survival 2

Coordination of Care

• Refer to specialist palliative care for complex symptom management, though primary palliative care delivered by frontline clinicians is feasible and should be integrated routinely 7, 8, 9
• Patients with home mechanical ventilation should receive routine outpatient palliative care as part of home care 1
• Assess need for skilled nursing facility placement, home health services, or hospice if patient cannot manage medications, oxygen, and activities of daily living 6
