The purpose

Obstructive sleep apnea (OSA) is the most common type of sleep apnea. The marketplace currently does not have an affordable, easy-to-use, over-the-counter, home-based OSA screening device. An affordable, available, FDA-approved and easy-to-use over-the-counter OSA screening tool would allow greater screening of at-risk individuals, especially in underserved communities with low socioeconomic status, hopefully encouraging a greater proportion of such individuals to seek treatment for their condition. Over the past year, this investigative team has engineered a small screening device (Zerify®) for OSA and obtained preliminary evidence of its efficacy in a clinical population under a NIMHD-sponsored Phase I STTR award. Phase I Specific Aims 1 and 2 focused on developing a small (1.5 x 2.5 x 0.2 inches) semiconductor sensor that could store sound/motion data, transfer these data to a computer, and detect non-clinical simulated apnea events with a specificity and specificity exceeding 90%. Phase I Specific Aim 3 established the preliminary psychometric performance data of the screening device in a clinical sample of 52 patients (13% African American, 6% Asian, 4% Mixed or Other Race) against gold-standard polysomnography. Phase II proposal aims to optimize the engineered hardware and associated OSA algorithms, create a patient companion app and wireless healthcare provider dashboard, and compare the efficacy of this screening device to the most commonly utilized sleep apnea screener, the home sleep apnea test (HSAT).
