The investigators have developed a simple, accurate, and a point-of-care, computer-based clinical decision support system (CDSS) not only to detect the presence of sleep apnea but also to predict its severity. The CDSS is based on deploying an artificial neural network (ANN) derived from anthropomorphic and clinical characteristics.

The investigators hypothesize that patients with severe OSA defined as AHI≥30 can be diagnosed with the use of ANN without undergoing a sleep study, and that empiric management with auto-CPAP has similar outcomes to those who undergo a formal sleep study.

Primary Outcome Measures:
  • To demonstrate that using an ANN directed management of OSA is not inferior to PSG directed management of OSA in terms of sleepiness related functional outcome [ Time Frame: 6 weeks ]

Enrollment: 0
Study Start Date: January 2011
Study Completion Date: June 2015
Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: artificial neural network Other: computer model
Diagnosis of Sleep apnea and treatment guidance will rely on a computer model prediction.
Active Comparator: Polysomnogram Other: Polysomnogram
Diagnosis of sleep apnea will rely on polysomnogram
