Managing Pain, Fatigue, and Difficulty Breathing
Physicians should routinely assess these three symptoms using brief standardized tools (visual analog or numeric rating scales) at every encounter and initiate evidence-based treatments immediately, as inadequate symptom control represents poor quality of care. 1
Systematic Assessment Approach
Begin by determining the underlying context and life expectancy, as this fundamentally changes management strategy—whether the patient has years, months-to-weeks, or weeks-to-days to live guides the aggressiveness and goals of intervention. 1, 2
Initial Symptom Evaluation
- Assess pain intensity using numeric rating scales (0-10) at every visit, as lack of awareness of patient pain is a major barrier to adequate management. 1
- Screen for fatigue systematically, recognizing it is often the most prevalent symptom but frequently goes unrecognized and undertreated. 1
- Evaluate dyspnea severity using validated scales, and in non-communicative patients, assess physical signs like labored breathing as indicators of respiratory distress. 1, 2
- Screen concurrently for depression, as pain, fatigue, and dyspnea often cluster together, and treating depression may improve other symptoms. 1
Pain Management Algorithm
Follow the WHO three-step analgesic ladder, which provides adequate relief for the majority of patients. 1
Step 1: Mild Pain
- Start with NSAIDs (e.g., ibuprofen 400-800mg every 6-8 hours) for mild pain, using the lowest effective dose for the shortest duration necessary. 1, 3
- Monitor for gastrointestinal bleeding risk, particularly in patients with prior ulcer history, those taking corticosteroids/anticoagulants, older age, or alcohol use. 3
Step 2: Moderate Pain
- Add a weak opioid to the NSAID when pain persists or increases. 1
Step 3: Severe Pain
- Substitute a strong opioid for moderate-to-severe pain. 1
- For opioid-naïve patients, start morphine 2-10mg PO every 2 hours as needed or 1-3mg IV every 2 hours as needed, adjusting for patient size, age, and organ dysfunction. 1, 2
- Use around-the-clock dosing rather than as-needed to improve adherence and outcomes. 1
- Titrate opioids to symptoms with no specified dose limit, as concerns about respiratory depression should not prevent adequate pain control. 1, 2
- If patients receive two bolus doses in one hour, double the infusion rate; for patients already on opioid infusions, give bolus doses equal to two times the hourly rate for breakthrough pain. 1
Adjuvant Therapies
- Add adjuvants for neuropathic pain and to manage opioid side effects. 1
- Consider external beam radiotherapy for localized pain and bisphosphonates for bone metastases pain. 1
- Order anti-nausea medications PRN with all opioid prescriptions. 1
Dyspnea Management Algorithm
For Patients with Years of Life Expectancy
- Treat underlying causes first: consider radiation/chemotherapy for malignancies, therapeutic drainage for cardiac/pleural/abdominal fluid, bronchoscopic therapy, bronchodilators, diuretics, steroids, antibiotics, or transfusions as indicated. 2
- Provide oxygen therapy only for hypoxemia (target saturation >94%) or when patients report subjective relief, as oxygen is ineffective in non-hypoxemic patients. 1, 2
- Implement nonpharmacologic interventions: fans directed at the face, cooler room temperatures, stress management, and relaxation therapy. 2
For Patients with Months-to-Weeks of Life Expectancy
- Administer morphine 2.5-10mg PO every 2 hours as needed or 1-3mg IV every 2 hours as needed for opioid-naïve patients experiencing dyspnea. 2
- Increase opioid doses by 25% for patients already on chronic opioids when dyspnea develops. 2
- Add benzodiazepines specifically for dyspnea associated with anxiety: start lorazepam 0.5-1mg PO every 4 hours as needed. 1, 2
- Consider noninvasive positive-pressure ventilation (CPAP/BiPAP) for severe but potentially reversible conditions. 2
- Manage fluid overload by decreasing or discontinuing enteral/parenteral fluids and consider low-dose diuretics. 2
- Treat excessive secretions with scopolamine 0.4mg subcutaneous every 4 hours as needed or 1.5mg patches (1-3 patches every 3 days), or alternatives like atropine 1% ophthalmic solution or glycopyrrolate 0.2-0.4mg IV/subcutaneous every 4 hours. 2
For Acute Heart Failure with Dyspnea
- Administer sublingual/IV nitrates titrated to blood pressure in the absence of cardiogenic shock. 1
- Give IV diuretics (furosemide) for volume overload. 1
- Initiate non-invasive ventilation (CPAP) promptly if respiratory distress is detected. 1
Fatigue Management
Recognize that fatigue has limited proven treatment options, but addressing contributing factors is essential. 1
- Treat underlying depression with adequate doses and duration of antidepressants, as this may improve fatigue. 1
- Consider cognitive-behavioral and psychosocial interventions, which show modest benefit. 1
- Reassess regularly, as fatigue management requires ongoing evaluation and adjustment. 1
Critical Implementation Strategies
- Develop and utilize institutional protocols for systematic symptom assessment and management. 1
- Educate both physicians and patients about symptom management expectations and treatment algorithms. 1
- Perform continuous quality-improvement interventions with regular reassessment and follow-up of symptom scores. 1
- Ensure all opioid prescriptions are refillable with proper verification to maximize convenience and compliance. 1
Common Pitfalls to Avoid
- Do not undertitrate opioids due to unfounded fears of respiratory depression—when appropriately dosed for symptoms, opioids are safe and effective. 1, 2
- Do not reduce opioid doses solely for decreased blood pressure, respiration rate, or level of consciousness when opioids are necessary for adequate dyspnea and pain management in dying patients. 1
- Do not overlook depression screening, as patients may associate stigma with psychiatric diagnosis and be reluctant to report symptoms. 1
- Do not delay palliative interventions until the very end of life, as early implementation improves quality of life. 2
- Do not rely on oxygen therapy alone for non-hypoxemic patients with dyspnea, as it provides no benefit. 2
- Do not fail to address the psychological and emotional components of these symptoms, which can significantly amplify their intensity. 2
