Abstract:
OBJECTIVE: To provide updated American College of Rheumatology (ACR) recommendations on rheumatoid arthritis (RA) disease activity measurements to facilitate a treat-to-target approach in routine clinical care.
METHODS: A working group conducted a systematic literature review from the time of the prior ACR recommendations literature search. Properties of disease activity measures were abstracted, and study quality was assessed using the Consensus-Based Standards for the selection of Health Measurement Instruments 4-point scoring method, allowing for overall level of evidence assessment. Measures that fulfilled a minimum standard were identified, and through a modified Delphi process preferred measures were selected for regular use in most clinic settings.
RESULTS: The search identified 5,199 articles, of which 110 were included in the review. This search identified 46 RA disease activity measures that contained patient, provider, laboratory, and/or imaging data. Descriptions of the measures, properties, study quality, level of evidence, and feasibility were abstracted and scored. Following a modified Delphi process, 11 measures fulfilled a minimum standard for regular use in most clinic settings, and 5 measures were recommended: the Disease Activity Score in 28 Joints with Erythrocyte Sedimentation Rate or C-Reactive Protein Level, Clinical Disease Activity Index, Simplified Disease Activity Index, Routine Assessment of Patient Index Data 3, and Patient Activity Scale-II.
CONCLUSION: We have updated prior ACR recommendations for preferred RA disease activity measures, identifying 11 measures that met a minimum standard for regular use and 5 measures that were preferred for regular use in most clinic settings.
