Are sleep studies appropriately done in the home?
For many years the greatest barrier to the diagnosis and treatment of obstructive sleep apnea (OSA) was recognizing the disease. That obstacle is now fading as more physicians of all types are aware of the high prevalence of OSA and the consequences of untreated OSA. Sleep-laboratory polysomnography has long been considered the accepted standard for OSA diagnosis and has become a lucrative practice. This, unfortunately, has led to a concentration on diagnosis rather than on management of OSA. Although several brands of portable polysomnograph have been approved for home polysomnography, obstacles to reimbursement (primarily from government, but also from private payers) have prevented widespread home polysomnography. Over the last 2 decades many scientific studies have supported a strong correlation between the findings from home polysomnography and sleep-laboratory polysomnography. However, limited data are available from good outcomes-oriented studies, so controversy surrounds home polysomnography in the diagnosis of OSA. We review the evidence and debate whether sleep studies are appropriately done in the home.
