Clinical Trial Summary

The purpose of this study is to determine whether a novel intervention combining cognitive behavioral therapy for insomnia plus a positive airway pressure (PAP) behavioral adherence program provided by allied health personnel for older Veterans with obstructive sleep apnea and comorbid insomnia improves nighttime sleep and PAP adherence.

Description:

Sleep disturbance is common in older adults and is associated with increased healthcare utilization, more depressive symptoms, and other adverse effects on health-related quality of life. Obstructive sleep apnea (OSA) is a disorder characterized by repetitive episodes of complete or partial upper airway obstruction occurring during sleep. OSA increases in prevalence with age, and is associated with increased risk of cardiovascular disease, decreased quality of life, and increased mortality. Insomnia also increases in prevalence with age, and is associated with numerous adverse outcomes, including cognitive decline, decreased quality of life, increased healthcare costs and increased mortality. The diagnostic criteria for insomnia include a decreased ability to fall asleep or stay asleep, frequent nighttime awakening or poor quality sleep that is associated with daytime impairment such as fatigue, impaired attention, or daytime sleepiness. Increasing evidence suggests that insomnia often coexists with OSA, particularly in older adults, and predicts worse outcomes of OSA. Both OSA and insomnia have a higher prevalence among Veterans, compared to the general population.

Little is known of the best approaches to manage the large number of patients with coexisting OSA and comorbid insomnia. Guidelines for best practice typically address these conditions separately, where positive airway pressure (PAP) is the standard for the treatment of OSA, and cognitive behavioral therapy for insomnia (CBT-I) is considered first-line treatment for chronic insomnia. CBT-I is particularly recommended for insomnia in older adults, where adverse effects of sleeping medications are most problematic. Early adherence to PAP therapy (i.e., within the first week of PAP therapy) is one of the strongest predictors of long-term PAP adherence. However, adherence rates to PAP therapy in patients with OSA are low. In addition, CBT-I has not been widely implemented for treatment of insomnia (in part due to limited access to mental health specialists able to provide CBT-I), untreated OSA limits response to treatment of insomnia, and untreated insomnia negatively impacts PAP adherence.

Based on this evidence and findings from the investigators' prior work, the investigators believe that an integrated, behavioral treatment approach which addresses both OSA and insomnia early in the course of PAP therapy is needed to maximize patient adherence and treatment success when these conditions coexist. The investigators propose a randomized controlled trial to test a novel, behavioral approach integrating best practices for management of both conditions among older Veterans with OSA who are prescribed PAP therapy and have comorbid insomnia. The purpose of this project is to determine whether this intervention improves nighttime sleep and PAP adherence.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sleep Quality	Total score on the Pittsburgh Sleep Quality Index will be used as a measure of sleep quality. Scores range from 0 to 21. Higher scores indicate worse outcome.	Three months after randomization
Primary	Sleep Onset Latency From Sleep Diary	Sleep onset latency (minutes to fall asleep) will be calculated from 7 days of self-reported sleep diary. Minimum value is 0 minutes. Maximum possible value is 1,440 minutes (24 hours). Higher scores indicate worse outcome.	Three months after randomization
Primary	Wake After Sleep Onset From Sleep Diary	Wake after sleep onset (minutes awake from sleep onset to get up time) will be calculated from 7 days of self-reported sleep diary. Minimum value is 0 minutes. Maximum possible value is 1,440 minutes (24 hours). Higher scores indicate worse outcome.	Three months after randomization
Primary	Sleep Efficiency From Sleep Diary	Sleep efficiency (mean percent time asleep while in bed) will be calculated from 7 days of self-reported sleep diary. Scores range from 0 to 100 percent. Higher scores indicate better outcome.	Three months after randomization
Primary	Sleep Efficiency From Wrist Actigraphy	Sleep efficiency (mean percent time asleep while in bed) will be calculated from 7 days of wrist actigraphy. Scores range from 0 to 100 percent. Higher scores indicate better outcome.	Three months after randomization
Primary	PAP Adherence	Number of nights positive airway pressure (PAP) was used >=4 hours during the first 90 days measured by remote monitoring. Scores range from 0 to 90 days. Higher scores indicate better outcome.	Three months after randomization
