Feasibility and acceptance of self-applied home type-II PSG studies with a patch-based device.

Area of Science:

• Sleep Medicine
• Medical Devices
• Biomedical Engineering

Background:

• The Onera Sleep Test System (STS) 1 is the first wireless, patch-based Type-II polysomnography (PSG) system designed for home use.
• This study aimed to evaluate the device's performance and user experience in a real-world home setting.

Purpose of the Study:

• To assess the success rate of the Onera STS 1 for home sleep studies.
• To gather participant feedback on the usability and satisfaction with the device.

Main Methods:

• A multicenter observational study included 41 patients with suspected sleep disorders.
• Participants performed home sleep studies using the Onera STS 1 after minimal instruction and returned the device by mail.
• Data were uploaded and independently scored by experts according to American Academy of Sleep Medicine (AASM) criteria.

Main Results:

• 83% of home sleep studies were of sufficient quality for diagnosis, and 87.8% met rule-based success criteria.
• High signal quality was observed, with approximately 80% of signals providing over 5 hours of scorable data.
• Excellent inter-scorer agreement was found for all sleep parameters, and participant satisfaction was high, with 90.7% recommending the device.

Conclusions:

• The patch-based home PSG device demonstrated high success rates, excellent signal quality, and high participant satisfaction.
• The Onera STS 1 is a viable, user-friendly alternative to in-lab PSG for comprehensive sleep assessment in a home environment.
