More Daytime Sleeping Predicts Less Functional Recovery among Elderly Undergoing Inpatient Post-Acute Rehabilitation
The elderly are at high risk for functional decline during acute hospitalization, which can lead to increased care-giving needs at home, nursing home placement, or death. There has been some research addressing the importance of sleep in rehabilitation settings, but disturbance in sleep/wake patterns has not yet been explored as a potential factor impacting functional outcomes among the elderly. This study sought to describe the sleep patterns among older people in the post-acute rehabilitation setting – and to examine them as a potential predictor of functional recovery. Investigators analyzed data from 245 patients ages 65 and older who received care at either a for-profit community nursing home or a VAMC inpatient rehabilitation unit. Reasons for admission to rehabilitation were varied; for example, orthopedic problems (42.1%), cardiac problems (13.2%) and stroke (10.6%).
Findings show that more daytime sleep during the rehabilitation stay was associated with less functional recovery from admission to discharge, even after adjusting for other significant predictors (e.g., mental status, reason for admission, and hours of rehabilitation therapy). Further, more daytime sleep remained a predictor of less functional recovery at 3-month follow-up.
