The comparative burden of chronic spontaneous urticaria, atopic dermatitis and psoriasis in five European countries

Abstract Background Skin diseases can have a significant impact on the physical, psychological and social well‐being of patients. Quantification of the burden of chronic spontaneous urticaria (CSU) compared to other dermatological conditions is limited. Objectives To evaluate the comparative humanistic and economic burden of CSU, atopic dermatitis (AD), and psoriasis (PSO) in five European countries (EU5). Methods This cross‐sectional analysis compared data from adult respondents with a physician diagnosis of CSU, AD and PSO from the 2020 National Health and Wellness Survey in EU5 (France, Germany, Italy, Spain and the United Kingdom). Outcomes included Short Form (SF)‐12v2 [mental (MCS) and physical component (PCS) summary scores], SF‐6D, EQ‐5D, EQ‐Visual Analogue Scale (VAS), Dermatology Life Quality Index (DLQI), General Anxiety Disorder‐7 (GAD‐7), Patient Health Questionnaire‐9 (PHQ‐9), Work Productivity and Activity Impairment (WPAI) and healthcare resource utilization (HRU). Multivariable analyses comparing CSU to AD and PSO, respectively, were conducted for each outcome. Results This analysis included 379 CSU, 788 AD and 2,636 PSO patients. Adjusted MCS and PCS scores were lower among CSU patients than AD (MCS, p = 0.006; PCS, p
