Real-World Treatment Patterns, Resource Use and Costs in Adult Patients With Atopic Dermatitis Receiving Systemic Treatment: Derma-Atopic Study in Spain. / [Artículo traducido] Características de los pacientes, patrones de tratamiento, uso de recursos y costes en adultos con dermatitis atópica moderada-grave en la práctica habitual en España: Estudio Derma-Atopic.

BACKGROUND: Moderate-severe atopic dermatitis (AD) has a significant impact on patients' lives, with many requiring systemic treatment to manage symptoms (e.g., pruritus). Several drugs are used off-label to treat AD. This study describes sociodemographic/clinical characteristics, treatment patterns, health resource use (HRU) and costs in adults with AD who initiated systemic treatment or phototherapy in routine practice. METHODS: This retrospective observational study of electronic medical records in the BIG-PAC database identified adults with prior diagnosis of AD (ICD-9: 691.8 or 692.9) starting oral corticosteroids, immunosuppressants, biologics or phototherapy between 01/01/2012 and 31/12/2016. Patients were followed for 3 years from treatment initiation, up to 31/12/2019. Data on patient characteristics, treatment patterns, HRU and costs were analyzed descriptively. RESULTS: Patients (N = 1995) had a mean age of 60 years, 64% were female, with a mean time of 23 years since diagnosis (84% were ≥18 years at AD onset). Main comorbidities were anxiety (38%), arterial hypertension (36%) and dyslipidemia (35%). Most patients used oral corticosteroids as first systemic (84%; median duration 29 days) and immunosuppressants in 13% of patients (median duration 117 days, 5% cyclosporine and 4% methotrexate). Half of patients required a second line systemic and 12% a third line. The use of immunosuppressants and biologics increased with treatment lines. About 13% of patients received systemic treatments continuously over the 3-year follow-up. The average 3-year per patient cost was 3835 euros, with an average annual cost of 1278 euros. CONCLUSIONS: Results suggest a high comorbidity and economic burden in this real-world adult population with AD, and the need for systemic treatments indicated for use in AD.

Patient-Reported Outcome Measures in Real-World Atopic Dermatitis Studies in Spain: A Systematic Review. / Medidas de los resultados percibidos por el paciente en estudios de vida real en dermatitis atópica en España: revisión sistemática de la literatura.

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.
