Cognitive and behavioral therapy for insomnia increases the use of continuous positive airway pressure therapy in obstructive sleep apnea participants with comorbid insomnia: a randomized clinical trial.

Comorbid insomnia and sleep apnea (COMISA) can affect a patient’s ability to accept and comply with continuous positive airway pressure (CPAP) therapy. Providing adequate treatment for these patients can be challenging.
Sweetman et al11 evaluated the acceptance and use of CPAP in patients with obstructive sleep apnea and chronic insomnia following initial treatment with CBT-I compared with treatment as usual (TAU).
- In this RCT, 145 participants with COMISA were randomized to 4 sessions of CBT-I or TAU before starting CPAP therapy until 6 months after randomization.
- Primary outcomes were objective CPAP adherence and objective sleep efficiency at the end of 6 months.
- Secondary outcomes were CPAP acceptance/rejection, changes in sleep parameters, global insomnia severity, and daytime impairments at 6 months.
