Abstract

Objective: Systematic reviews often struggle with how to combine information when more than 1 instrument is used across studies being synthesized. Different techniques have been suggested based on frequency of use in the literature, or on consensus. We explore an approach blending 2 initiatives: OMERACT (Outcome Measurement in Rheumatology) and COSMIN (Consensus On Selection of Measurement Instruments), and investigate the effects of an evidence-based measurement approach on selection of outcomes.

Methods: Readings were circulated to attendees registered for a preconference workshop on pain measurement. Three instruments were considered and exercises conducted to engage people in the content and measurement performance of these tools. Consensus was sought that an evidence-based approach could be created for selection of instruments for summary of findings (SoF) tables.

Results: The blending of COSMIN and OMERACT approaches led to an evidence-based approach that depended both on a clear definition of target concept and a review of measurement performance of the instrument. Participants emphasized that conceptual clarity and practical considerations should come before measurement property results.

Conclusion: Evidence-based approaches can be adopted for selection of instruments for SoF tables. A research agenda was formulated.
