Abstract

Objectives: To develop an operational definition of contextual factors (CF) [1].Methods: Based on previously conducted interviews, we presented three CF types in a Delphi survey; Effect Modifying-, Outcome Influencing -and Measurement Affecting CFs. Subsequently, a virtual Special Interest Group (SIG) session was held for in depth discussion of Effect Modifying CFs.Results: Of 161 Delphi participants, 129 (80%) completed both rounds. After two rounds, we reached consen-sus (>70% agreeing) for all but two statements. The 45 SIG participants were broadly supportive.Conclusion: Through consensus we developed an operational definition of CFs, which was well received by OMERACT members. (c) 2021 The Authors.
