Development of a Core Domain Set of Outcomes for Shared Decision Making Interventions: An Omeract White Paper and Stakeholder Interviews.

OBJECTIVE: The Outcome Measures in Rheumatology (OMERACT) shared decision making (SDM) Working Group aims to determine the core outcome domain set for measuring the effectiveness of SDM interventions in rheumatology trials.

METHODS: A white paper was developed to clarify the draft core domain set. It was then used to prepare stakeholders for interviews to explore reasons for lack of consensus on it and to suggest further improvements.

RESULTS: OMERACT scientists/clinicians (n=13) and patients (n=10) suggested limiting the core domain set to outcome domains, removing process domains, and clarifying remaining domains.

CONCLUSION: A revised core domain set will undergo further consensus-building.
