Methods Working Groups

Strengthening the Science Behind Core Outcome Sets

OMERACT Methods Working Groups provide the methodological backbone of OMERACT by continuously improving how Core Outcome Sets (COS) and their related methodologies are developed and implemented.

These groups focus on refining methods for domain selection, instrument evaluation, and meaningful patient engagement, ensuring that all OMERACT Working Groups apply consistent, transparent, and evidence-based approaches.

Click on a group below to learn more about their goals, progress, and contributions and find out how you can get involved.

Composite Outcomes: Developing best practices for developing composite outcome measures and bringing them through the OMERACT Filter.

Contextual Factors: Providing guidance on how external factors influence outcomes in rheumatology trials.

Equity, Diversity & Inclusivity (EDI): Promoting inclusive participation, accessibility, and global representation across all OMERACT activities.

Patient Engagement in OMERACT: Implementing the PEIR Framework and PEIRS-22 tool to strengthen meaningful patient engagement.

Patient preferences to value health outcomes for RCT's: Developing methods to incorporate patient preferences in outcome definitions.

Surrogate Outcomes: Evaluating how surrogate endpoints can reliably predict clinical benefit in rheumatology research.
