A Randomized Controlled Study Assessing the Role of an Ambulatory Approach Versus the Conventional Approach in Managing Suspected Obstructive Sleep Apnoea Syndrome
In Brief
A clinical study evaluating Home sleep study and conventional polysomnography for OSA. Completed, enrolled 316 participants across 1 site.
Detailed 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.

Timeline
Interventions
The home sleep study is a pocket-sized digital recording device. It is a multi-channel screening tool that measures airflow through a nasal cannula connected to a pressure transducer, providing an apnea-hypopnea index (AHI) based on recording time. It also detects both respiratory and abdominal efforts through the effort sensor and can differentiate between obstructive and central events
conventional type I sleep study according to international guidelines
