Extract

In this issue of CHEST (see page 257), another study from Canada by Skomro et al1 shows that home-based limited-channel diagnostic testing for obstructive sleep apnea has equivalent short-term outcomes compared with in-laboratory polysomnography. This study is consistent with three other studies that were conducted similarly.2-4 There are similar themes with these studies: All were performed at a single tertiary-care center, the patients were evaluated by physicians trained in sleep medicine, patients were at significant risk for obstructive sleep apnea, and those with comorbidities were excluded. This particular study is unique in that all patients underwent both home testing and laboratory testing but were treated according to the primary randomization (home testing with autotitrating positive airway pressure [autoPAP] or laboratory testing with continuous positive airway pressure [CPAP] titration); in the other studies, patients only got one test instead of both. All of these outcome studies demonstrated that, for this specific population of patients, it did not matter how their apnea was diagnosed; they used their CPAP device about the same amount of time and received about the same improvement from its use.
