Abstract

Background: UK studies examining vitiligo burden and vitiligo-related healthcare resource utilization (HCRU) are lacking. Objective: To describe the incidence and prevalence of vitiligo, the demographic and clinical characteristics of patients with vitiligo, vitiligo burden, HCRU, incidence of mental health comorbidities and management strategies, including treatment patterns. Methods: This retrospective study used UK Clinical Practice Research Datalink and Hospital Episode Statistics databases to analyse patients with vitiligo from 1 January 2010 to 31 December 2021. Results: Among 17 239 incident patients, mean incidence of vitiligo was 0.16 (2010–2021) per 1000 person-years [PY; range 0.10 (2020–COVID-19) to 0.19 (2010/2013/2018)]; among 66 217 prevalent patients, prevalence increased from 0.21% (2010) to 0.38% (2021). The most common comorbidities recorded after vitiligo diagnosis were diabetes (19.4%), eczema (8.9%), thyroid disease (7.5%) and rheumatoid arthritis (6.9%). Mental health diagnoses recorded at any time included depression and/or anxiety (24.6%), depression (18.5%), anxiety (16.0%) and sleep disturbance (12.7%), and recorded after vitiligo diagnosis in 6.4%, 4.4%, 5.5% and 3.9%, respectively. Mental health comorbidities were more common in White (e.g. depression and/or anxiety 29.0%) than in Black (18.8%) and Asian (16.1%) patients. In adolescents, depression and/or anxiety was most commonly diagnosed after a vitiligo diagnosis than before (7.4% vs. 1.8%). Healthcare resources were used most frequently in the first year after vitiligo diagnosis (incident cohort), typically dermatology-related outpatient appointments (101.9/100 PY) and general practitioner consultations (97.9/100 PY). In the year after diagnosis, 60.8% of incident patients did not receive vitiligo-related treatment (i.e. topical corticosteroids, topical calcineurin inhibitors, oral corticosteroids or phototherapy), increasing to 82.0% the next year; median time from diagnosis to first treatment was 34.0 months (95% confidence interval 31.6–36.4). Antidepressants and/or anxiolytics were recorded for 16.7% of incident patients in the year after diagnosis. In 2019, 85.0% of prevalent patients did not receive vitiligo-related treatments. Conclusion: Most patients were not on vitiligo-related treatments within a year of diagnosis, with the time to first treatment exceeding 2 years, suggesting that vitiligo may be dismissed as unimportant. New effective treatments, early initiation and psychological intervention and support are needed to reduce the vitiligo burden on patients.
