Abstract
STUDY OBJECTIVES: To examine the proportion of Medicare beneficiaries with sleep disorders who were evaluated by board-certified sleep medicine providers (BCSMPs). METHODS: Using a random 5% sample of Medicare administrative claims data (2007-2011), BCSMPs were identified by employing a novel cross-matching approach based on National Provider Identifiers available within the Medicare database. Sleep disorders were included based partially on the International Classification of Sleep Disorders, Third Edition (insomnia, sleep-related breathing disorders, hypersomnias, circadian rhythm sleep-wake disorders, parasomnias, and restless legs syndrome), and operationalized as International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes. The proportion of beneficiaries with each disorder who were seen by BCSMPs and nonspecialists was computed. RESULTS: Among older adult Medicare beneficiaries with sleep disorders, the most common sleep disorder was insomnia (n = 65,033), and the least common sleep disorder was narcolepsy (n = 784). Individuals with central sleep apnea (n = 1,561) were most likely to be treated by a BCSMP (63.9% of beneficiaries with central sleep apnea), and individuals diagnosed with insomnia were least likely to be treated by a BCSMP (16.4% of beneficiaries with insomnia). Most BCSMPs treated beneficiaries with obstructive sleep apnea (84.9% of BCSMPs) and insomnia (75.8% of BCSMPs). CONCLUSIONS: BCSMPs are involved in the care of a substantial proportion of Medicare beneficiaries with sleep disorders.
