Home sleep apnea testing has increased due to improvements in technology, accessibility, and changes in the third party reimbursement requirements. Research studies using HSAT have not consistently reported procedures and methodological challenges. This paper had two objectives: (1) summarize the literature on the use of HSAT in research of adults and (2) identify methodological strategies to use in research and practice to standardize HSAT procedures and information.
Methods: Search strategy included studies of participants undergoing sleep testing for OSA using HSAT, MEDLINE via PubMed, CINAHL, and Embase with the following search terms: “polysomnography,” “home,” level III,” “obstructive sleep apnea,” and “out of center testing.”
Results: Research articles that met inclusion criteria (n=34) inconsistently reported methods and methodological challenges in terms of: (a) participant sampling; (b) instrumentation issues; (c) clinical variables; (d) data processing; and (e) patient acceptability. Ten methodological strategies were identified for adoption when using HSAT in research and practice.
Conclusion: Future studies need to address the methodological challenged summarized in this paper as well as identify and report consistent HSAT procedures and information.
