Tight control of rheumatoid arthritis (RA) may be guided by RAPID3 (routine assessment of patient index data), an index without formal joint counts or laboratory tests, which can be scored on a multidimensional health assessment questionnaire (MDHAQ) in 5 seconds, compared to 42 seconds to score a standard HAQ, 90 seconds to perform a 28-joint count, 114 seconds to score a disease activity score 28 (DAS28), and 106 seconds to score a clinical disease activity index (CDAI). RAPID3 scores are correlated significantly with DAS28 and CDAI (rho > 0.65, p < 0.001), and distinguish active from control treatment similarly to DAS28 and CDAI in clinical trials of methotrexate, lefunomide, adalimumab, abatacept, certolizumab, and infiximab. RAPID3 scores can be used to classify patient disease activity status as high (> 12), moderate (6.1-12), low (3.1-6), and remission (
