Assessment of Tender & Swollen Joints Count Score Performed by a Rheumatologist And Rheumatology Nurses in Patients With RA and PsA.

Patients will complete a self-evaluation of 28 joint counts for swelling and tenderness and assess their disease activity on a Visual Analog Scale. A 28 joint count and VAS will then be assessed by a nurse and by a rheumatologist. The same rheumatologist will examine all patients and two nurses will each randomly assess half the total enrolled patients. The nurse will be blinded to the patient's joint count and VAS, and similarly, the rheumatologist will be blinded to both the patient and nurse's assessments.
