Outcome Measures for Psoriasis Severity: A Report from the GRAPPA 2012 Annual Meeting

Abstract

At the 2012 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) in Stockholm, Sweden, dermatology members provided summaries of ongoing work with outcome measures for psoriasis severity. Controversies around the physician global assessment (PGA) were summarized, including discussions of variations and limitations of the static PGA instruments in use. The Psoriasis Outcome Measures project was introduced, with a goal of developing measures for use in clinical trials and practice. This project will follow the Outcome Measures in Rheumatology (OMERACT) process and may become a model for outcome measures of other dermatologic diseases.
