Clinical validation of a wireless patch-based polysomnography system
2025
Overview
Study Objectives:
Onera Health has developed the first wireless, patch-based, type-II polysomnography (PSG) system, the Onera Sleep Test System, to allow studies to be performed unattended at the patient’s home or in any bed at a medical facility. The goal of this multicenter study was to validate data collected from the patch-based PSG to a traditional PSG for sleep staging and apnea-hypopnea index.
Methods:
Simultaneous traditional PSG and patch-based PSG study data were obtained in a sleep laboratory from 206 participants with a suspected sleep disorder recruited from 7 clinical sites. Blinded, randomized scoring of the traditional PSG and patch-based PSG recordings was completed according to
The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications
(Version 2.6) criteria by 3 independent scorers.
Results:
Concordance correlation coefficients were high between the patch-based device and traditional PSG across essential sleep and respiratory variables—total sleep time (.87); wake (.84); non-rapid eye movement (REM) (.80); non-REM sleep stage 1 (N1) (.72); non-REM sleep stage 2 (N2) (.71); non-REM sleep stage 3 (N3) (.64); REM (.80); and apnea-hypopnea index (AHI) (.94). There was substantial agreement between epoch sleep staging scored on the patch-based device and traditional PSG (average Cohen’s kappa of 0.62 ± 0.13 across all scorers).
Conclusions:
The patch-based type-II PSG had a similar performance on sleep staging and respiratory variables when compared to traditional PSG, thus making it possible to use the patch-based PSG for a routine PSG study. These results open the possibility of performing unattended PSG studies efficiently and accurately outside the sleep laboratory improving access to high quality sleep assessments for patients with sleep disorders.
