Assessment of treatable contributing factors for fatigue should include:
1) Treatment complications (anemia, infection, fever)
2) Weight/caloric intake changes (how much weight loss)
3) Fluid and electrolyte imbalances (sodium, calcium, potassium, magnesium)
4) Medications (opioids, antihistamines, antidepressants, alcohol/recreational drug use)
5) Other symptoms/side effects (ESAS greater than or equal to 4 for pain, depression, anxiety, and sleep disturbances)
6) Activity level changes (decreased activity, decreased exercise patterns)
7) Co-morbid conditions contributing to fatigue
