Psoriasis and psoriatic arthritis video project: an update from the 2010 GRAPPA annual meeting.

Changes in severity of psoriasis and psoriatic arthritis (PsA) are assessed in clinical trials by a variety of physical examination instruments. At the 2010 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), members were updated on the development and availability of modules that teach these instruments. Web-based interactive multimedia presentations for psoriasis assessments have been completed, including modules for Psoriasis Area and Severity Index and Body Surface Area, 5-point and 6-point Physician Global Assessment, the original and modified Nail Psoriasis Severity Index, the Palmar-Plantar Pustular Psoriasis Area and Severity Index, and the Psoriasis Scalp Severity Index. Rheumatology modules will include assessment of tender and swollen joints, and evaluations of enthesitis, dactylitis, and axial disease. Each module will include the background and rationale for each tool, demonstration video of each examination, diagrams and photographs to emphasize teaching points, and an optional examination at the end. The rheumatology modules have been recorded but were not yet available for review at the meeting. The dermatology modules are currently in use by pharmaceutical and biotechnology companies engaged in research on treatments for psoriasis and PsA. The next phase of this project includes analysis of interobserver reliability, translation into languages other than English for international users, and other proposed studies.
