Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are veterans aged 18 and older with a diagnosis of PTSD and substance use disorder who also have obstructive sleep apnea.

Probably not a fit

Patients with central sleep apnea or those already using a PAP device prior to the study may not benefit from this intervention.

What this trial studies

This study investigates the effects of positive airway pressure (PAP) treatment for obstructive sleep apnea (OSA) in veterans who are undergoing residential treatment for post-traumatic stress disorder (PTSD) and substance use disorder (SUD). It compares the outcomes of veterans receiving PAP therapy to those on a waitlist control group. The study aims to determine if treating OSA can improve overall treatment adherence and outcomes for veterans struggling with these co-occurring conditions. Given the high comorbidity of OSA with PTSD and SUD, this approach seeks to enhance recovery during a critical time in the veterans' treatment journey.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life and recovery outcomes for veterans suffering from PTSD and substance use disorder.

How similar studies have gone: Other studies have shown promising results in treating OSA in populations with PTSD and SUD, suggesting that this approach may be effective.
