Obstructive Sleep Apnea
Conditions
Brief summary
A prospective, randomised, blinded pilot study comparing the Sunrise solution and overnight polygraphy for the diagnosis of OSA in adult patients. Patients under investigation for OSA will use both devices simultaneously for a single overnight sleep study. They will be randomised to receive their treatment decision based on either the Sunrise solution or polygraphy. A retrospective check of their diagnosis will be done.
Interventions
DEVICESunrise
Sunrise (Sunrise SA, Belgium) is a novel integrated digital medicine solution for the diagnosis of OSA allowing the detection of respiratory disorders from the analysis of mandibular movements optimised by an artificial intelligence algorithm machine learning. It is composed of a unique innovative sensor, placed on the chin during the night, connected via Bluetooth to a mobile application which guides the patients for the implementation and allows the transfer of the data collected by the sensor to a certified health host guaranteeing the security and confidentiality of medical data. The analysed data is integrated and automatically transferred into a detailed report made available to doctors via a secure website the day after the test.
DEVICEPolygraphy
Polygraphy (Apnoealink-Air, ResMed, Australia) is a commercially available, limited-channel sleep study device which can be used in the home. Many sleep services in the UK already use the ApneaLink Air for routine screening. It is a portable device which consists of a nasal cannula to measure nasal flow and snoring, oximeter to measure pulse and blood oxygen levels, and a chest band to measure respiratory effort. It contains software which allows for the scoring of apnoeas, hypopnoea and arousals.

Masking description
Patients under investigation for OSA will use both devices (Sunrise solution and overnight polygraphy) simultaneously for a single overnight sleep study. They will be randomised to receive their treatment decision based on either the Sunrise solution or polygraphy. They will be unaware of which device their treatment decision was based on.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to treatment decision | From date of sleep study device dispatch until the date of treatment decision, assessed typically within 1 month but up to 6 months | Time (days) from sleep study device dispatch to treatment decision |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to treatment decision; RBH vs NHS Scotland Sleep Service | From date of sleep study device dispatch until the date of treatment decision, assessed typically within 1 month but up to 6 months | Time (days) from sleep study device dispatch to treatment decision; inner London (Royal Brompton hospital) vs Scottish Highlands (NHS Scotland Sleep Service) |
| AHI | After completion of the sleep studies and data from both devices is available; typically within 1 month but up to 6 months | Apnoea-hypopnoea index compared between sleep study devices; Sunrise and polygraphy |
