Ramelteon vs Placebo for Prevention of Delirium and Improvement of Sleep in Hospitalized Older Adults

Delirium in Old Age Clinical Trial

Official title:
Ramelteon vs Placebo for Prevention of Delirium and Improvement of Sleep in Hospitalized Older Adults

Clinical Trial Summary

This study evaluates whether Ramelteon can prevent delirium, decrease the severity of incident delirium and improve sleep wake cycle in hospitalized elderly surgical patients. Half of the patients will be assigned to Ramelteon, while other half will be assigned to placebo.

Clinical Trial Description

Delirium is a common clinical syndrome characterized by acute cognitive dysfunction with core features of inattention, disorganized thinking, perceptual disturbances and sleep-wake cycle disruption. It is typically multifactorial and can be triggered by acute infection, metabolic derangements, surgery, and certain medications. Older adults have a much higher incidence of delirium. Delirium increases in-hospital mortality, length of stay, rate of institutionalization and may cause or exacerbate cognitive impairment. The present pilot study investigates sleep loss as potentially important contributing factors in delirium and an opportunity for intervention. Sleep disruption is prevalent among hospitalized patients. Sufficient sleep is important for recovery from illness, management of pain, wound healing, and a variety of other biologic functions integral to recovery in addition to its putative role in delirium prevention. Melatonin plays an important role in circadian rhythms and sleep-wake cycle regulation. Melatonin secretion is altered in hospitalized older patients in comparison with community-living older individuals. Melatonin and the melatonin-receptor agonist Ramelteon have been studied and have shown promise in delirium prevention, in addition to promoting sleep. We propose to test the use of Ramelteon to decrease delirium and improve sleep/wake cycles in the elderly surgical patients. ;
