Musculoskeletal ultrasound may narrow the gap between patients and physicians in the assessment of rheumatoid arthritis disease activity

Objectives To investigate the association between patient-physician discordance in the assessment of disease activity and residual US synovitis/tenosynovitis in a cohort of patients with RA in clinical remission. Methods A post hoc analysis of the STARTER study, promoted by the Musculoskeletal-US (MSUS) Study Group of the Italian Society for Rheumatology, was performed using data from 361 consecutive patients with RA in clinical remission. The global assessment of disease activity by each patient (PGA) and evaluator/physician (EGA) was recorded on a 100-mm visual analogue scale. The PGA-EGA discordance was classified as positive (PGA>EGA) or negative (PGA
