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.
Keywords: OMERACT; cohort studies; observational studies; patient registries; patient-centered outcomes; rheumatoid arthritis.
