Key clinical point: A referral tool based on five independent risk factors for concomitant psoriatic arthritis (PsA) among patients with psoriasis may help dermatologists to identify patients with psoriasis who could benefit from a rheumatologist referral.
Major finding: The predictive variables for concomitant PsA among patients with psoriasis that were included in the referral tool were treatment history with conventional systemics ( P = .04) and biologics/small molecule inhibitors ( P = .01), patient-reported history of joint pain without trauma ( P = .02), swollen joints ( P < .001), and sausage-like swollen digits ( P = .01). The referral tool had an area under curve of 0.82.
Study details: This study analyzed the data of 303 patients with psoriasis from the prospective observational DAPPER study who had visited the dermatology outpatient clinic.
Disclosures: This study was funded by a PhD grant from Radboud University Medical Center/Sint Maartenskliniek, Netherlands, and local structural research funding of the Sint Maartenskliniek. Several authors reported financial and non-financial ties with various sources.
