MedicalResearch.com: What are the main findings of the study?
Dr. El Shayeb: Our study shows that limited channel level-3 portable devices, used at home, are of good diagnostic value compared to the comprehensive reference-standard level-1 sleep tests conducted in lab in the diagnosis of obstructive sleep apnea (the most common subtype of sleep disordered breathing.)
Were any of the findings unexpected?
None of the findings were unexpected. Level-3 portable devices are commonly used in clinical practice; however, this technology has been widely disseminated, without solid evidence about their diagnostic performance or the subpopulation of sleep disordered breathing patients who are most appropriately diagnosed with them. Our research provides a high level of evidence on the diagnostic performance of these devices, and most importantly, defines the subgroup of patients who are eligible for this test (patients with simple obstructive sleep apnea, and without significant comorbidities.)
