Outcome Measures in Rheumatology (OMERACT)

OMERACT (Outcome Measures in Rheumatology) is an international effort to develop standardized ways to assess how well treatments work for rheumatic diseases like arthritis. It aims to identify consistent, reliable measures—such as pain levels, joint function, and quality of life—that can be used across studies and in clinical practice. This helps doctors and researchers better understand treatment effects, compare results, and improve patient care. Essentially, OMERACT ensures that everyone uses the same meaningful criteria to evaluate disease progress and treatment success in rheumatology.
