Patient-Reported Outcome Measures in Real-World Atopic Dermatitis Studies in Spain: A Systematic Review

Atopic dermatitis (AD) is a chronic inflammatory skin disease with symptoms such as pruritus that can be a major burden for patients. Patient-reported outcomes (PRO) complement clinician-reported outcomes in AD. This systematic review aims to identify and describe patient-reported outcome measures (PROM) used in observational studies of AD over the last decade in Spain. Eighteen PROM were identified to measure 13 different PRO that assess multiple aspects of the disease, including symptoms and disease severity, impact on daily activities and on work productivity/functioning, psychosocial impact, patient empowerment, and health-related quality of life (HRQoL). HRQoL, symptoms (particularly pruritus), and anxiety/depression were the most frequently assessed PRO, and the Dermatology Quality of Life Index, the Visual Analogue Pruritus Scale, and the Hospital Anxiety and Depression Scale were the most frequently used PROM, respectively. The growing number of observational studies on AD including PROM in Spain suggests that PRO are becoming increasingly important in the management of AD.
