Development of an item bank to measure factual disease and treatment related knowledge of rheumatoid arthritis patients in the treat to target era.

Objective: To develop a Disease and treatment associated Knowledge in RA item bank (DataK-RA) based on item response theory.

Methods: Initial items were developed from a systematic review. Rheumatology professionals identified relevant content trough a RAND modified Delphi scoring procedure and consensus meeting.

Systematic review of patient-reported outcome measures (PROMs) for assessing disease activity in rheumatoid arthritis.

Patient assessment of disease activity in rheumatoid arthritis (RA) may be useful in clinical practice, offering a patient-friendly, location independent, and a time-efficient and cost-efficient means of monitoring the disease. The objective of this study was to identify patient-reported outcome measures (PROMs) to assess disease activity in RA and to evaluate the measurement properties of these measures. Systematic literature searches were performed in the PubMed and EMBASE databases to identify articles reporting on clinimetric development or evaluation of PROM-based instruments to monitor disease activity in patients with RA.
