The European prevalence of vitiligo diagnosis is 0.2%-0.8%, with country-specific and methodological differences. Although vitiligo profoundly impacts quality of life, limited studies have evaluated disease burden and treatment patterns. This real-world study describes the prevalence, incidence, characteristics, and treatment patterns of vitiligo among patients in Spain during 2015-2021. This retrospective observational study using the IQVIA Electronic Medical Records database in Spain included patients with vitiligo (International Classification of Diseases, Ninth Revision codes 709.01/374.53). Incident and prevalent cohorts comprised registered patients with vitiligo diagnoses during and before 2015-2021, respectively. Patient characteristics and treatment data were extracted. Vitiligo incidence was 0.016 (95% CI: 0.014-0.018) per 100 person-years, and prevalence was 0.19% (95% CI: 0.18%-0.19%) in 2021. Females were more affected than males (0.16% vs 0.13%, respectively). Among 1,400 incident patients, mean (SD) age was 40.7 (19.7) years; most were female (53.9%). The most common comorbidities after vitiligo diagnosis were eczema (20.8%), hypercholesterolaemia/hypertriglyceridaemia (17.9%), anxiety (10.9%), thyroid disorders (9.1%), and diabetes (6.4%). In 2021, 78.6% of prevalent patients did not receive vitiligo-related treatments. The most prescribed vitiligo-related treatments were topical calcineurin inhibitors (13.9%) and topical corticosteroids (13.0%); 11.9% had a record of psychiatric medications. This study confirms the association between vitiligo and comorbidities (e.g., eczema, thyroid disorders) and high disease burden. The prevalence in Spain in 2021 (0.19%) was within the lower band of European estimates based on surveys/medical screenings. Most patients are not receiving vitiligo-related treatment and could benefit from new, effective treatments.
