ObjectiveThe aim of this study was to evaluate the function of a cohort of patients with rheumatoid arthritis (RA) from the core set of the International Classification of Functioning and Health (ICF) for RA over 12 months.MethodsWe used prospective longitudinal data to conduct a cohort study among a well-characterized group of RA patients. Ninety RA patients aged between 40 and 70 years were included in the study. Patients were evaluated at baseline and after 12 months. Age, disease duration, current smoking, erosions, disease activity, functional test, disability and physical activity were evaluated. Then, the ICF core set classification for RA was applied.Results81 patients completed the assessments, the majority of patients were female (88.9%) and the mean age was 56.5 ± 7.3 years. At baseline, the median disease activity was 3.0. There was a statistically significant (p ConclusionWe conclude that relevant aspects of the ICF Core Set for RA were able to adequately express the physical and functional factors of the RA cohort. This tool provides a common language for the interdisciplinary team, which can enhance the use of timely interventions to prevent physical disability in clinical practice.
