Strategies to promote implementation of core outcomes for medication adherence trials in rheumatology: A report from the OMERACT-Adherence Group

Objectives: To identify barriers, facilitators, and strategies for future implementation of the OMERACT-Adherence Core Outcome Set (COS) in medication adherence trials for rheumatic conditions. Methods: Preliminary Delphi survey findings were discussed at OMERACT 2023, utilising the Consolidated Framework for Implementation Research 2 to identify implementation barriers, facilitators, and solutions. Results: Implementation strategies included simplifying the COS definitions, making it adaptabile for clinical practice and drug trials, adherence trial training workshops, and collaborating with key stakeholders such as payers and other COS developers. Conclusion: Ongoing collaboration with individuals and organisations within and beyond rheumatology ensures broader applicability of OMERACT-Adherence COS.
