Patient-Reported Outcomes in Psoriatic Arthritis.

Patient-reported outcome (PRO) measures are an important component to assessing disease impact and therapy response in patients with psoriatic arthritis (PsA). Overall, there are few PsA-specific PROs. Most PROs used in PsA are borrowed from other diseases (eg, rheumatoid arthritis and ankylosing spondylitis) or general population PROs. PROs are used in PsA clinical trials and in the clinical management of PsA. In this review, we discuss the most commonly used PRO in PsA, including their inclusion in composite measures. Future studies may be helpful to determine the best performing PROs in patients with PsA.
