Summary

Very few studies have examined different models of care involving initial ambulatory home-based diagnosis in diagnosing obstructive sleep apnea (OSA), identifying patients who benefit from continuous positive airway pressure (CPAP), and reducing the need for polysomnography (PSG). This study aims to assess the role of an ambulatory approach with home diagnostic sleep study. We hypothesize that the ambulatory approach is as good as the conventional approach in managing OSA in terms of improvement of clinical outcome but the former approach will lead to substantial cost savings.

Eligibility Criteria

Inclusion Criteria

  • symptoms of OSA with home sleep study AHI >= 15/hr.

Exclusion Criteria

  • unstable cardiovascular diseases (e.g. recent unstable angina, myocardial infarction, stroke or transient ischemic attack within the previous 6 months or severe left ventricular failure)
  • neuromuscular disease affecting or potentially affecting respiratory muscles
  • moderate to severe respiratory disease (i.e. breathlessness affecting activities of daily living) or documented hypoxemia or awake oxygen saturation of <92%
  • psychiatric disease that limits the ability to give informed consent or complete the study
