(1314) Consumer Sleep Technology and Obstructive Sleep Apnea Treatment: A Scoping Review

Introduction: Consumer sleep technologies (CSTs) may offer an accessible means to track longitudinal treatment outcomes in obstructive sleep apnea (OSA). This study aimed to synthesize existing literature on the utility of CSTs in monitoring patients undergoing OSA therapy.

Methods: A literature search was performed using PubMed, Embase, and Web of Science databases. The search strategy, developed with a senior informationist at our institution, utilized terms to capture a broad range of CSTs (wearable devices, smartphone applications, and under-mattress sensors) and titratable OSA treatments, including oral appliance therapy (OAT) and surgical interventions such as hypoglossal nerve stimulation (HGNS). Title, abstract, and full-text screening were performed by two reviewers with subsequent narrative synthesis.

Results: Of 176 studies identified, 4 studies with N=87 patients met inclusion criteria. All evaluated CSTs in conjunction with HGNS. No OAT studies met inclusion criteria. Two studies (50%) used the Oura Ring, one (25%) the Withings Sleep Mat, and one (25%) the SnoreLab smartphone application. The Oura Ring provided total sleep time, wake after sleep onset, and sleep onset latency, with one study also assessing heart rate and heart rate variability. SnoreLab reported snoring intensity and duration, while the Sleep Mat was the only device estimating nightly apnea-hypopnea index. CST-derived data generally correlated with subjective sleep quality and standard sleep assessments.

Conclusions: CSTs enable longitudinal tracking of sleep and physiologic metrics in patients undergoing titratable OSA therapies. However, available data are sparse and limited to HGNS, highlighting the need for future research evaluating CSTs across a broader range of OSA treatments.
