Randomized Controlled TrialRoutine Assessment of Patient Index Data 3 and the American College of Rheumatology/European League Against Rheumatism Provisional Remission Definitions as Predictors of Radiographic Outcome in a Rheumatoid Arthritis Clinical Trial With Tocilizumab.
The American College of Rheumatology/European League Against Rheumatism established definitions of remission for rheumatoid arthritis (RA) based on composite scores, including tender (TJC) and swollen joint counts (SJC), patient global visual analog scale (VAS) score, laboratory tests, and, in the Simplified Disease Activity Index (SDAI), the physician global score. Time constraints on a physician's schedule demand an easy yet accurate tool to measure disease activity. We assessed the predictive ability of the Routine Assessment of Patient Index Data 3 (RAPID3) with and without a single swollen joint versus the SDAI and/or Boolean remission criteria for functional and radiographic outcomes. ⋯ The predictive ability of RAPID3 (with or without joint count) was similar to that of SDAI and Boolean criteria.
