0546 Patient-reported Experience with a Wireless Patch-Based Polysomnography System – Results from a Pilot Study

Abstract Introduction Sleep is critical for health and wellbeing. Left untreated, sleep disorders negatively impact daily functioning and quality of life. The gold-standard for sleep monitoring and diagnosis is in-lab polysomnography (PSG). Though PSG provides a comprehensive overview of sleep, it is uncomfortable due to the amount of sensors, which prohibit movement and disturb sleep. A wireless patch-based PSG system, the Onera Sleep Test System (STS), consisting of four body-worn sensors, was recently introduced to overcome these limitations. The objective of this study is to evaluate patient-reported experience when using the Onera STS. Methods Forty-two patients were enrolled in Germany as part of an ongoing validation study. Participants were asked to fill in two questionnaires. The first, administed before the Onera STS sleep study, asked open-ended questions on their first impression of the device. The second, administered after the Onera STS sleep study, focused on the ease of use of the device and comfort of wearing it during the night using a 5-point Likert scale. Results Thirty-six patients completed the first questionnaire (85%) and 39 (93%) the second. First impression of the Onera STS was positive by 86% of patients. The size of the sensors was described as acceptable by 72%. Participants stated that the device looked more comfortable than in-lab PSG and they expected improved sleep quality and a more accurate diagnosis. After completing the PSG with the Onera STS system, 69% found wearing the four sensors comfortable, and no participant expressed strong discomfort during the sleep study. The Forehead sensor was considered the most comfortable (based on 77% stating strongly agree or agree), followed by the Abdomen sensor (74%), the Leg sensor (72%), and the Chest sensor (69%). Most participants (72%) expressed confidence in their ability to fit the sensors by themselves at home. Only one participant preferred to be supported by a technician for the application of the system. Conclusion The first impression of the Onera STS device were positive, and participants found it comfortable during sleep. The majority considered the application simple enough for unsupervised self-application, which can allow patients to undergo a PSG in the comfort of their own home. Support (if any)
