Fatigue--a rational approach to investigation

Area of Science:

• General Practice
• Internal Medicine
• Diagnostic Medicine

Background:

• Fatigue is a frequent primary care complaint with diverse potential causes, though significant somatic pathology is rare.
• Fatigue presentations often result in extensive testing, but yield few significant diagnoses.
• Australian and international guidelines exist for managing fatigue.

Purpose of the Study:

• To present a rational, evidence-based approach to investigating fatigue.
• To integrate international literature with recent Australian guidelines for fatigue assessment.

Main Methods:

• Comprehensive literature review.
• Analysis of existing Australian and international fatigue investigation guidelines.

Main Results:

• A structured approach to fatigue assessment is crucial.
• Identifying 'red flags' is key to determining the need for immediate investigation.
• Judicious use of diagnostic tests is recommended post-initial assessment.

Conclusions:

• A thorough patient history and physical examination are paramount.
• Watchful waiting is a viable strategy when no red flags are present.
• Diagnostic testing should be selective and guided by clinical findings.
