Chief complaint of fatigue: a prospective study

Area of Science:

• Primary Care Research
• General Internal Medicine
• Psychiatry

Background:

• Fatigue is a common chief complaint in primary care settings.
• Understanding the origins of fatigue is crucial for effective patient management.
• Previous research indicates a complex interplay of factors contributing to fatigue.

Purpose of the Study:

• To investigate the characteristics and origins of fatigue in patients presenting to primary care.
• To explore the relationship between physical, psychological, and health status in patients with fatigue.
• To identify factors differentiating physical from psychological origins of fatigue.

Main Methods:

• Prospective study conducted within the Dartmouth COOP Project, a primary care research network.
• Data collected from patients presenting with fatigue across 28 primary care practices.
• Assessment included fatigue status, associated symptoms, overall health status, and perceived origin of fatigue.

Main Results:

• Fatigue patients exhibited significantly poorer physical and mental health compared to non-fatigue patients.
• A majority of physicians and patients perceived fatigue as primarily physical, but a substantial portion acknowledged interacting physical and psychological factors.
• Depression and anxiety were key differentiators between fatigue of physical versus psychological origin.

Conclusions:

• Fatigue in primary care is associated with diminished health status and often has multifactorial origins.
• Clinicians should conduct thorough evaluations to understand the complex causes of fatigue.
• Effective communication regarding the multifaceted nature of fatigue is essential for treatment adherence.
