About the Psoriatic Arthritis Working Group
Psoriatic arthritis (PsA) is an inflammatory musculoskeletal disease occurring in 7–42% of patients with psoriasis. Arthritis, enthesitis, dactylitis, spondylitis, and skin disease result in pain, stiffness, reduced mobility, impairment in physical function, and subsequent disability. PsA is now recognized as a disease that can be serious and progressive despite treatment, resulting in significant physical, psychological, functional, and social impairment.
The updated PsA Core Domain Set was endorsed at OMERACT 2016. Next steps for the PsA working group include evaluation of PsA outcome measures and development of a PsA Core Outcome Measurement Set
