A summary of the article is shown below:

Rationale: Lack of timely access to diagnosis and treatment of sleep-disordered breathing (SDB) has sparked interest in using nonphysician providers. Previous studies of these alternative care providers (ACPs) excluded patients with more complicated forms of SDB and did not directly explore the impacts of a model incorporating ACPs on healthcare system performance, such as wait times.Objectives: To evaluate the use of ACPs in the management of patients with severe SDB from a clinical and system perspective.Methods: In this noninferiority study, patients with severe SDB (N = 156) were enrolled from October 2014 to July 2016 and randomized to either sleep physician management or management by ACP with same-day sleep physician review. Severe SDB was defined as one of 1) respiratory event index greater than 30/h, 2) mean nocturnal oxygen saturation less than 85%, and 3) arterial carbon dioxide greater than 45 mm Hg with respiratory event index greater than 15/h. The primary outcome was nightly positive airway pressure adherence at 3 months, using a noninferiority margin of 1 hour. Secondary outcomes included sleepiness, quality of life, patient satisfaction, wait times for diagnosis and treatment initiation, and demand for further testing and clinical assessment. Outcomes were evaluated using modified intention-to-treat and per-protocol analyses.Results: Care delivery using ACPs was indeterminate compared with sleep physician care with respect to treatment adherence, because the 95% confidence interval included the noninferiority margin of 1 hour (mean difference, -0.5 [-1.49 to 0.49] h). Patients in the ACP arm reported greater improvements in sleepiness and quality of life; wait times were shorter for initial assessment (28%) and treatment initiation (18%). There was no difference in demand for sleep testing or clinical follow-up. Per-protocol analysis revealed similar results.Conclusions: Management of severe SDB using ACPs was indeterminate compared with sleep physician care. The small decrease in adherence in the ACP arm was balanced by benefits in patient-reported outcomes and reduction in wait times. In systems with unacceptably long wait times for SDB diagnosis and treatment, a small decrease in treatment adherence, as was observed in this study, may be an acceptable trade-off to improve access to care for patients with severe SDB.Clinical trial registered with http://www.clinicaltrials.gov (NCT02191085).
