  "abstract": "Background Polysomnography (PSG) performed in sleep laboratories is the diagnostic gold standard, but laboratory schedules, unfamiliar surroundings, and equipment burden may distort natural sleep. Home PSG systems could capture more representative sleep patterns while preserving full signal fidelity. The Onera Sleep Test System (STS) is a patient applied, patch-based, type II PSG system, which enables studies to be performed unattended at the patient’s home.Methods In a two-phase, multicenter study across seven German sleep clinics, adults referred for PSG first underwent in-lab patch-based PSG (N=344) (Age: 50.6 ± 12.7; BMI: 30.7 ± 6.2; Gender: 66.3% Male/33.7% Female) and eligible participants then completed a home PSG within one week (N=179) (Age: 50.1 ± 12.7; BMI: 30.7 ± 5.9; Gender: 68% Male/32% Female).Results Lab sleep timing ranged widely between the clinical sites, with average lights off times as early as 20:49 and lights on as early as 4:52. Differences in sleep patterns were found between the two environments (lights-off 23:00 ± 84.5 min home vs 22:10 ± 47.36 min lab; lights-on 06:33 ± 108.4 min home vs 05:34 ± 45.7 min lab). When comparing weeknight hPSG studies (74%) differences between environments remained large (lights-off 22:54 ± 75.4 min home vs 22:16 ± 39.8 min lab; lights-on 06:22 ± 101.1 min home vs 05:42 ± 49 min lab). When analyzing sleep architecture in the scored subset on a patient’s chosen hPSG night, home nights showed longer total sleep time (409.5 ± 74.5 vs 378.2 ± 71.8 min, p=0.033), more REM sleep (91.1 ± 28.1 vs 76.7 ± 28.4 min, p=0.024), higher sleep efficiency (88.9% ± 9.0 vs 80.9% ± 11.9, p<0.001), lower WASO (24.3 ± 24.1 vs 54.8 ± 45.1 min, p<0.001), shorter REM onset latency (85.5 ± 47.7 vs 108.2 ± 64.7 min, p=0.008), and a lower arousal index (1.86 ± 1.64 vs 2.89 ± 2.11, p=0.003). Sleep architecture showed less significant differences when comparing weeknight sleep studies. 73% of subjects indicated that their sleep in the lab was ‘worse than home’.Conclusions These findings support home PSG to obtain more representative sleep architecture without compromising detection of sleep-disordered breathing.",
