Consensus Building in OMERACT: Recommendations for Use of the Delphi for Core Outcome Set Development

Abstract

OBJECTIVE: Developing international consensus on outcome measures for clinical trials is challenging. The following paper will review consensus building in Outcome Measures in Rheumatology (OMERACT), with a focus on the Delphi. METHODS: Based on the literature and feedback from delegates at OMERACT 2018, a set of recommendations is provided in the form of the OMERACT Delphi Consensus Checklist. RESULTS: The OMERACT delegates generally supported the use of the checklist as a guide. The checklist provides guidance for clearly outlining the multiple aspects of the Delphi process. CONCLUSION: OMERACT is deeply committed to consensus building and these recommendations should be considered a work in progress.
