Is insomnia a marker for psychiatric disorders in general hospitals?
This study found a high prevalence of psychiatric disorders and insomnia in a general hospital population and found that insomnia can be a marker for MDE.
The findings suggest that fatigue is an important independent predictor of pain interference and not merely a mediator. These findings also suggest that not all fatigue is created equal. Interventions aimed at reducing pain interference should target specific fatigue symptoms of physical fatigue and vigor. Future research investigating the independent associations of fatigue subtypes on pain outcomes may help clarify the nature of the interrelationships between pain and fatigue.
