Patient Perspectives on Outcome Domains of Medication Adherence Trials in Inflammatory Arthritis: An International OMERACT Focus Group Study.

Objective: To describe the perspectives of patients with inflammatory arthritis (IA) on outcome domains of trials evaluating medication adherence interventions.

Methods: Adult patients (≥ 18 yrs) with IA taking disease-modifying antirheumatic drugs from centers across Australia, Canada, and the Netherlands participated in 6 focus groups to discuss outcome domains that they consider important when participating in medication adherence trials. We analyzed the transcripts using inductive thematic analysis.
