Sleep disturbances in long-term care.

Nighttime sleep disruption is characteristic of long-term care residents, is typically accompanied by daytime sleepiness, and may be caused by a multitude of factors. Causal factors include medical and psychiatric illness, medications, circadian rhythm abnormalities, sleep disordered breathing and other primary sleep disorders, environmental factors, and lifestyle habits. There is some suggestion that these factors are amenable to treatment; however, further research on the implementation of treatments within the long-term care setting is needed. Additional work is also needed to understand the administrative and policy factors that might lead to systemic changes in how sleep is viewed and sleep problems are addressed in long-term care settings.
