A13.1 Conduct a patient-centred interview to

  1. Define what the patient means by “fatigue” and distinguish it from other concerns e.g. mood concerns, muscle weakness, decreased exercise tolerance.
  2. Identify clinical symptoms/red flags that suggest a secondary etiology, e.g. depression, anemia, hypothyroidism, malignancy, sleep apnea, cardiac disease.
  3. Identify the social determinants of health that may suggest psychosocial concerns and impact differential diagnosis and/or management, e.g. Homelessness, isolation, single parent, addiction, recent losses, sleep quality/shift work.

A13.2 Conduct a relevant physical exam to refine different diagnosis.

A13.3 Propose initial investigations based upon differential diagnosis, while avoiding over-investigation

A13.4 Develop a management plan based upon the clinical scenario and results of initial investigations

A13.5 Understand when to include “watchful waiting” as an appropriate diagnostic and/or management tool.
