Management of Fatigue
Fatigue should be managed through a tailored approach that addresses underlying causes, incorporates physical activity, energy conservation strategies, and cognitive-behavioral interventions, with pharmacologic options reserved for specific indications. 1
Assessment and Screening
- Fatigue is a subjective experience that requires systematic assessment using patient self-reports
- Screen for fatigue at initial visits, during treatment, and at follow-up appointments
- Use a 0-10 numeric rating scale (moderate fatigue ≥4, severe fatigue ≥7)
- Evaluate for common contributing factors:
- Medical conditions (anemia, hypothyroidism, pain, sleep disorders)
- Medications (opioids, antihistamines, beta-blockers)
- Emotional distress (anxiety, depression)
- Physical deconditioning
- Nutritional deficiencies
- Comorbidities
Management Algorithm
Step 1: Treat Underlying Causes
Correct medical conditions:
- Treat anemia if hemoglobin is low
- Manage hypothyroidism with levothyroxine (note: monitor for adverse effects including fatigue if overdosed) 2
- Address pain with appropriate analgesics
- Treat sleep disorders (insomnia, sleep apnea)
Review and modify medications:
- Adjust timing of sedating medications
- Consider alternatives for medications with fatigue as a side effect
Step 2: Non-Pharmacologic Interventions
Physical Activity (highest level of evidence):
- Implement structured exercise program combining endurance and resistance training
- Start with low intensity and gradually increase based on tolerance
- Aim for 150 minutes of moderate-intensity activity per week when possible
Energy Conservation Strategies:
- Set priorities and realistic expectations
- Schedule activities during peak energy times
- Delegate non-essential tasks
- Use labor-saving devices
- Limit naps to 1 hour to avoid interfering with nighttime sleep 1
Cognitive-Behavioral Interventions:
- Address negative thought patterns about fatigue
- Develop coping strategies
- Set achievable goals
- Consider referral to psychologist or therapist trained in CBT
Sleep Hygiene:
- Maintain consistent sleep schedule
- Create restful sleep environment
- Avoid caffeine and electronics before bedtime
- Limit daytime napping
Step 3: Pharmacologic Interventions (for specific indications)
Psychostimulants:
Wakefulness agents:
- Modafinil may be considered for patients with advanced disease or during active treatment 1
- Not recommended for routine use in disease-free survivors
Special Considerations
Cancer-Related Fatigue
- Particularly common during and after cancer treatment (30-60% during treatment, 20-30% post-treatment) 1
- Often persists for months or years after treatment ends 1
- May require disability support and advocacy from healthcare providers 1
Inflammatory Rheumatic and Musculoskeletal Diseases
- Fatigue is prevalent in 50% of patients with inflammatory rheumatic conditions 1
- Associated with increased healthcare costs, work disability, and reduced quality of life 1
- Requires multidisciplinary approach including rheumatologists, nurses, occupational therapists, and psychologists
Common Pitfalls to Avoid
Underrecognizing fatigue - Fatigue is often under-reported, underdiagnosed, and undertreated despite being highly distressing to patients 1
Focusing only on physical causes - Fatigue is multifactorial with biological, psychological, and social mechanisms 1
Overlooking impact on quality of life - Fatigue significantly impacts all aspects of life including physical, emotional, social, and occupational functioning 1, 3
Dismissing fatigue as inevitable - Many patients and providers incorrectly assume fatigue is an unavoidable consequence of disease or treatment 1
Relying solely on pharmacologic management - Evidence supports non-pharmacologic approaches as first-line interventions, with medications reserved for specific indications
By implementing this comprehensive approach to fatigue management, healthcare providers can significantly improve patients' quality of life, functional status, and overall well-being.
