Health Resource Utilization and Associated Health Care Costs of Biologic Disease‐Modifying Antirheumatic Drugs in German Patients With Psoriatic Arthritis

<jats:sec><jats:title>Objective</jats:title><jats:p>To investigate health care costs associated with biologic disease‐modifying antirheumatic drugs (bDMARDs) in a German real‐world cohort of adult biologics‐naive patients with psoriatic arthritis (PsA).</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Claims data from the Institute for Applied Health Research Berlin (InGef) research database for patients with a PsA diagnosis and bDMARD claims record (index date) between January 1, 2014, and December 31, 2017, and no bDMARD prescriptions for 365 days before the index date were retrospectively analyzed. Primary outcomes were determination of health care resource utilization and associated annual health care costs for overall and individual bDMARDs in the 12‐month pre‐index and post‐index periods. These outcomes were compared between persistent and nonpersistent groups. Nonpersistence was defined as treatment gap or switch to a bDMARD other than the index therapy.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Among 10,954 patients with a PsA diagnosis, 348 were eligible. Although mean ± SD post‐index costs were significantly higher in the persistent group than the nonpersistent group (€27,869 ± 8,001 versus €21,897 ± 10,600, <jats:italic>P</jats:italic> < 0 .001) due to higher bDMARD acquisition costs (€23,996 ± 4,818 versus €16,427 ± 9,033, <jats:italic>P</jats:italic> < 0.001), persistence reduced inpatient treatment costs (–€760), outpatient treatment costs (–€192), other drug costs (–€724), and sick leave costs (–€601).</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Although initiation of bDMARDs increased the total health care costs irrespective of persistence status, partial cost offsets were observed in the persistent patient population.</jats:p></jats:sec>
