Live Recordings (Sleep Medicine Trends 2026)-16 Improving HSAT

Video Transcription

Video Summary

The panel reviews how home sleep apnea testing (HSAT) evolved from early “portable monitoring/OCST” amid initial resistance to broad adoption after Medicare approval and AASM guidelines. What began as a few mostly flow/effort/oximetry “type 3” devices has expanded into many options, including PAT- and ring-based systems and more algorithm-driven platforms. Clinicians describe different practice models: in-clinic dispense/return for speed and signal-checking, vendor-managed programs that can be slower and have higher unscorable rates, and mail-out programs that can be operationally efficient and sometimes show low technical failure.<br /><br />Key operational lessons include minimizing portals and workflow complexity, educating patients, providing tech support, and managing hidden costs (staff time, inventory, cleaning, battery capacity). Strategies to reduce failures include pre-checking signals on return, multi-night testing, and devices that confirm adequate acquisition remotely.<br /><br />Multiple speakers emphasize always reviewing raw data rather than relying solely on auto-scoring, especially with newer nontraditional sensors. Central apnea indices on HSAT often prompt in-lab PSG confirmation (common cutoff CAI ≈5), particularly when considering hypoglossal nerve stimulation or other eligibility thresholds. The discussion also covers payer-driven barriers, HSAT underestimating AHI due to using recording time, limited pediatric guidance, and the rise of direct-to-consumer HSAT/CPAP pathways that may bypass comprehensive sleep care.
