Development Of A Patient-Centered Core Domain Set For Prospective Observational Longitudinal Outcome Studies In Rheumatoid Arthritis: An Omeract Initiative

Objectives: To identify patient-centered core domains for prospective longitudinal observational studies (LOS) in rheumatoid arthritis. Methods: Our working group held a virtual meeting in November 2020 to review data from a literature review and patient qualitative interviews, and to discuss strategies to move forward on domain identification and selection using the OMERACT 2.1 domain selection process. Results: Important candidate domains and subdomains were identified including in the areas of life impact. Consensus was reached on moving forward with a Delphi process. Conclusions: The meeting provided future directions to identify and select a core set of domains for use in LOS. (c) 2021 Elsevier Inc. All rights reserved.
