Prevalence of narcolepsy and other sleep disorders and frequency of diagnostic tests from 2013-2016 in insured patients actively seeking care.

Study Objectives: The primary objective was to describe trends in the 2-year limited duration prevalence of narcolepsy from 2013-2016 in a large insured population with claims activity. Secondary objectives were to assess the prevalence of other sleep disorders and the frequency of diagnostic sleep testing.

Methods: Nationwide medical/prescription claims (Symphony Health) were analyzed to estimate the annual prevalence per 100,000 persons of narcolepsy and other sleep disorders (obstructive sleep apnea, idiopathic hypersomnia, rapid eye movement sleep behavior disorder, periodic limb movement disorder) and the frequency of diagnostic sleep testing.
