4. PsA Workshop – Breakout Groups u Instructions: –Each group to rank items to be included in a clinical trial from 1-14 in terms of importance. –If there are others not included which the group feels should be included, add them. –Identify those that are absolutely critical for inclusion in a core set.

5. Discussion Issues u Several items were not actually domains –Active joint count is used to assess inflammation – replace with JOINT ACTIVITY –Radiology is a method not a domain – replace with STRUCTURAL DAMAGE –Spinal mobility is used to assess axial involvement – replace with AXIAL INVOLVEMENT

6. Discussion issues (Cont’d) u Three core sets ? –(skin, peripheral, axial disease) –One core set (psoriasis plus arthritis) u Should we look at peripheral joints and axial involvement separately? –Obviously different tools will be used –Should all patients with PsA be assessed for axial involvement? u How many joints to count? –68, 76, 44, 28 (parcimony vs. comprehensiveness)

7. Discussion issues (Cont’d) u Include Imaging to assess inflammation u Dactylitis and enthesitis combined –Concern about double counting u Meaning of damaged joint count –Deformities, flail joints, ankylosed joints, surgery u Patient global to reflect both skin and joint disease u Should add fatigue and sleep u Tissue assessment
