RAPID3 (Routine Assessment of Patient Index Data) on an MDHAQ (Multidimensional Health Assessment Questionnaire): agreement with DAS28 (Disease Activity Score) and CDAI (Clinical Disease Activity Index) activity categories, scored in five versus more than ninety seconds.

Objective: To compare the Routine Assessment of Patient Index Data 3 (RAPID3) on a Multidimensional Health Assessment Questionnaire (MDHAQ) with the Disease Activity Score (DAS28), Clinical Disease Activity Index (CDAI), and individual core data set measures for correlations, agreement of activity levels, and time to score.

Methods: Four rheumatologists each assessed 50 patients with rheumatoid arthritis in "real-time" clinical care. Patients completed an MDHAQ.
