Management of Fatigue and Insomnia in Shift Workers

Diagnosis and Assessment

The American Academy of Sleep Medicine recommends distinguishing fatigue from pathological sleepiness to suggest an alternative sleep disorder requiring urgent evaluation, as fatigue is the expected consequence of insomnia and shift work 1
The presence of involuntary napping episodes during the day or while driving mandates urgent polysomnography, as true sleepiness is uncommon in chronic insomnia 1

The American College of Physicians recommends cognitive behavioral therapy for insomnia (CBT-I) as the mandatory first-line treatment, even for subthreshold insomnia, due to its superior long-term efficacy compared to medications 2, 3
Strategic napping, such as two scheduled 15-20 minute naps, can significantly reduce sleepiness in shift workers, according to the Journal of the American Geriatrics Society 4
Sleep restriction therapy, which limits time in bed to actual sleep time, can improve sleep efficiency, as recommended by the Journal of the American Geriatrics Society 5, 3

The American Academy of Sleep Medicine suggests maintaining a consistent sleep-wake schedule, even on days off, to prevent further circadian disruption 4, 5
Creating a sleep-conducive environment, such as complete darkness, cool temperature, and white noise, can improve sleep quality, as recommended by the Journal of the American Geriatrics Society 5
Avoiding stimulants, such as caffeine, within 6 hours of planned sleep time, and avoiding alcohol, can help improve sleep quality 5

The American College of Physicians recommends obtaining 7-14 days of detailed sleep diary data before any pharmacological intervention to establish baseline patterns and guide treatment 3, 2
Monitoring for red flags, such as involuntary sleep episodes, cognitive impairment, mood deterioration, and quality of life decline, is crucial, as recommended by the American Academy of Sleep Medicine 1
Regular follow-up, such as every 2 weeks, is necessary to review sleep diary, assess behavioral intervention adherence, and screen for red flags 3
