The DigiTrace Home Sleep System (DHSS) provides reliable, high-quality unattended full polysomnography (PSG) in the home. This system expands access to PSG, offering a cost-effective alternative to in-lab studies.

Area of Science:

  • Sleep Medicine
  • Medical Device Technology
  • Biomedical Engineering

Background:

  • Polysomnography (PSG) is crucial for diagnosing sleep disorders but is often limited by resource constraints.
  • Home-based PSG offers a potential solution to increase accessibility and reduce costs.

Purpose of the Study:

  • To evaluate the DigiTrace Home Sleep System (DHSS) for unattended, in-home full polysomnography (PSG).
  • To compare the data acquisition, storage, and analysis capabilities of the DHSS with standard paper-based PSG.

Main Methods:

  • A prospective, cross-over design was used in Part 1 with 77 DHSS home recordings.
  • Part 2 involved a prospective, concurrent collection of data with DHSS and paper PSG in 16 patients.
  • Adult patients requiring clinical PSG, excluding those with abnormal behaviors needing video, were included.

Main Results:

  • The DHSS recorded 18 channels of high-quality polysomnographic data, with over 95% scorable epochs and no equipment failures.
  • Subjective patient feedback indicated no significant difference in perceived sleep representation between home and lab studies.
  • While patients preferred the lab experience due to minor home-study inconveniences, objective data showed no significant differences between DHSS and paper PSG.

Conclusions:

  • Unattended full PSG can be reliably performed at home using the DHSS, yielding high-quality recordings.
  • The DHSS facilitates the expansion of PSG to a larger patient population by overcoming limitations of bed availability.
  • This technology offers significant cost reductions by eliminating the need for overnight staff and facility resources.
