Abstract Multi-night measurement of obstructive sleep apnea (OSA) using AI-enabled technologies could reduce misdiagnosis rates from night-to-night variation. However, prospective feasibility and effectiveness of multi-night assessment in clinical populations remains uninvestigated. In this study, 100 people with suspected OSA were recruited to receive an under-the-mattress Withings Sleep Analyzer (WSA) to quantify in-home sleep for 3 months alongside single-night polysomnography.

Introduction Frailty is defined as a state of increased vulnerability to stressors, arising from a failure of homeostasis culminating in episodic deteriorations in health, leading to important adverse health outcomes, including a loss of independence for the older person (aged 65 or older)1, 2 and morbidity and mortality increments.
