RAPID3, an index to assess and monitor patients with rheumatoid arthritis, without formal joint counts: similar results to DAS28 and CDAI in clinical trials and clinical care.
RAPID3 (routine assessment of patient index data 3) is a pooled index of the 3 patient-reported American College of Rheumatology rheumatoid arthritis (RA) Core Data Set measures: function, pain, and patient global estimate of status. Each of the 3 individual measures is scored 0 to 10, for a total of 30. Disease severity may be classified on the basis of RAPID3 scores: >12 = high; 6.1-12 = moderate; 3.1-6 = low; < or =3 = remission. RAPID3 scores are correlated with the disease activity score 28 (DAS28) and clinical disease activity index (CDAI) in clinical trials and clinical care, and are comparable to these indices in capacity to distinguish active from control treatments in clinical trials. RAPID3 on a multidimensional health assessment questionnaire (MDHAQ) is scored in 5 to 10 seconds, versus 90 to 94 seconds for a formal 28-joint count, 108 seconds for a CDAI, and 114 seconds for a DAS28. An MDHAQ can be completed by each patient at each visit in the waiting room in 5 to 10 minutes, as a component of the infrastructure of routine care, with minimal effort of the rheumatologist and staff, to provide RAPID3 scores as well as additional data including a self-report joint count, fatigue, review of systems, and recent medical history. In all rheumatic diseases RAPID3 is able to provide a baseline quantitative value, and to quantitatively monitor and document improvement or worsening over time.
