Community Psoriasis: Phenotype and Comorbidity Assessment (COPPACA) was a study of the point prevalence and burden of untreated psoriasis in the Leeds urban area. There were high rates of undiagnosed psoriasis (41.1% of patients were newly diagnosed by the study team), and all patients (newly diagnosed or otherwise) reported significant psychosocial comorbidity [median Psoriasis Area and Severity Index (PASI) = 3 (interquartile range 1.7–6.8), PASI > 5 = 34%, mean Dermatology Life Quality Index (DLQI) = 8.45, DLQI ≥ 10 = 34.8%]. This highlights a significant unmet need for improved access to, and communication between, primary and secondary care dermatology in our area to improve patients’ physical and mental wellbeing.
