Utilization Patterns and Characteristics of Users of Biologic Anti-Inflammatory Agents in a Large, US Commercially Insured Population

We report utilization patterns and characteristics of patients treated with biologic anti‐inflammatory agents in a large commercially insured patient population in the United States. We identified adult (age ≥18 years) patients receiving biologic anti‐inflammatory agents between 1 January 2012 and 31 March 2019 across the five Research Partners in the Biologic and Biosimilars Collective Intelligence Consortium's Distributed Research Network. We examined the number of incident use episodes for each biologic, as well as patient demographic and clinical characteristics. Curated data and analytic tools from the Food and Drug Administration's Sentinel System were used to perform the analyses.
