Abstract
The “Discrimination” part of the OMERACT Filter asks whether a measure discriminates between situations that are of interest. “Feasibility” in the OMERACT Filter encompasses the practical considerations of using an instrument, including its ease of use, time to complete, monetary costs, and interpretability of the question(s) included in the instrument. Both the Discrimination and Reliability parts of the filter have been helpful but were agreed on primarily by consensus of OMERACT participants rather than through explicit evidence-based guidelines. In Filter 2.0 we wanted to improve this definition and provide specific guidance and advice to participants.
