Abstract: BACKGROUND: Patients with poor asthma control may receive oral corticosteroid (OCS) therapy despite the risk for adverse effects. OBJECTIVE: We assessed OCS use frequency and treatment patterns in patients with persistent asthma in the United States (US). METHODS: We used the IBM MarketScan Commercial Claims and Encounters, Medicare Supplemental, and Medicaid Multistate Claims research databases to identify patients from January 1, 2012, to December 31, 2017, who were ≥12 years old, met the 2-year Healthcare Effectiveness Data and Information Set criteria for persistent asthma, and were continuously enrolled ≥6 months before (baseline) and ≥24 months after (follow-up) the persistent asthma index date. Patients were classified as high OCS use (defined as ≥450 mg of OCS prescribed within a 90-day period during follow-up), low use (use OCS but not meeting high use criteria), or no OCS use. RESULTS: We identified 435,675 patients, of whom 65% used OCS and 19% were classified as high OCS users at some point during follow-up. The annual prevalence of high OCS use ranged from 5.3% in 2013 to 7.6% in 2017. During the entire follow-up, high and low OCS users filled an average of 2.2 and 0.8 OCS prescriptions and received an average daily dosage of 2.2 and 0.3 mg, respectively. Once the patients became high OCS users, the average daily OCS dosage was relatively stable (5.1-7.1 mg) over 3 years. CONCLUSIONS: Patients with persistent asthma in the US have substantial exposure to OCS. OCS therapy should be considered carefully to avoid associated adverse effects.
