Role of portable sleep studies for diagnosis of XXXX .

@entity1 @entity27 @entity387
PURPOSE OF REVIEW: There is growing awareness of the significance of @entity27 in the general population and in the medical community and, as a result, there is a growing demand for diagnosis and treatment. Attended, in-laboratory polysomnography is resource intensive and not readily available in some communities. Alternate diagnostic strategies have been proposed including the use of home sleep studies. Although these portable systems have been in use for many years, only in the past few years have a significant number of studies been performed to evaluate these systems in the home setting. The use of actigraphy and peripheral arterial tonometry for diagnostic purposes has also recently been investigated. RECENT FINDINGS: In the laboratory setting, measurements of @entity387 with specific portable sleep systems correspond well with measurements provided by standard polysomnography. In the home setting, portable systems demonstrate several important limitations including lost or inadequate data collection, logistic concerns, and mildly reduced diagnostic accuracy. Data regarding the potential cost benefit of home studies is inconclusive. SUMMARY: Home polysomnography is a viable option for evaluating @entity1 with moderate or high clinical suspicion for @entity387 . However, @entity1 with failed or equivocal home studies and those with negative studies but persistent symptoms should undergo standard polysomnography. Further investigations are needed to compare long-term outcomes in @entity1 evaluated using portable devices versus standard polysomnography.
