An index of only patient-reported outcome measures, routine assessment of patient index data 3 (RAPID3), in two abatacept clinical trials: similar results to disease activity score (DAS28) and other RAPID indices that include physician-reported measures

摘要

Objectives. To analyse the capacity of routine assessment of patient index data 3 (RAPID3), an index of only the three patient-reported outcome (PRO) measures in the RA Core Data Set—physical function, pain and global status—to distinguish abatacept from control treatments in two clinical trials, and to compare RAPID3 results with the disease activity score 28 (DAS28) and RAPID-based indices that add a tender or swollen joint count and/or physician/assessor global estimate of status.
