Abstract

Persons with traumatic brain injury (TBI) are at high risk for comorbid obstructive sleep apnea (OSA), with prevalence rates estimated between 25-66% [–]. Whether OSA precedes or follows TBI has been debated, with evidence of both directions. Studies have shown that TBI is independently associated with OSA [], and inversely that OSA patients were 1.23-fold more likely to later sustain a TBI after adjusting for demographics and comorbidities [].” However, the precise mechanisms linking OSA to TBI are poorly understood []. OSA is associated with deleterious health consequences, including cardiovascular disease [], severe cardiac events [], metabolic dysfunction [], diabetes [], and stroke []. Additionally, OSA leads to adverse outcomes such as mood disturbance, cognitive dysfunction, reduced productivity, workplace and motor vehicle accidents, and premature mortality [–]. The economic cost of OSA (i.e., health care costs; lost productivity) was estimated to exceed $149 billion in the year 2015 []. Fortunately, OSA is treatable. The American Academy of Sleep Medicine (AASM) recommends positive airway pressure (PAP) therapy as the first-line treatment for OSA []. While efficacious, adherence is poor. Approximately 42-59% of persons with OSA adhere to PAP therapy [–], with most studies using the Centers for Medicare & Medicaid Services adherence definition of ≥ 4 hours per night, ≥ 70% of the time []. Although an arbitrary cutoff, PAP use at this level has been associated with meaningful outcomes such as reduced risk of cardiac arrest [], stroke [–], and hospitalizations [] and lower health care costs []. Moreover, studies support a dose-response relationship; greater PAP use hours per night was associated with reduced daytime sleepiness and lower risk of atrial fibrillation [], hospitalization [], and cardiac events []. Also, PAP adherence has been positively associated with OSA severity []. While adherence using the conventional definition confers therapeutic benefit, PAP should be used throughout sleep duration to maximize health outcomes.
