Exploring racial and ethnic disparities in the hidradenitis suppurativa patient disease journey: Results from a real-world study in Europe and the USA.

Abstract

Hidradenitis suppurativa (HS) is an inflammatory skin disease associated with high morbidity and disability that has limited treatment options. People from racial and ethnic minority groups may experience greater disease severity and delay to diagnosis. This study assessed the impact of race/ethnicity on HS diagnosis and management in real-world clinical settings. Data were derived from the Adelphi Real World Hidradenitis Suppurativa Disease Specific Programme, a survey of dermatologists and their consulting HS patients in five European countries and the USA in 2020/2021. Dermatologists returned demographic and clinical data, and treatment goals and satisfaction for their next five to seven consulting patients. Patients completed a questionnaire on disease history and diagnosis, disease burden, and treatment satisfaction. Groups were compared with bivariate tests. In total, 312 physicians returned data on 1787 patients; 57.6% were female and 77.7% White. People from racial and ethnic minority groups were younger than White patients (32.9 ± 11.6 vs. 34.9 ± 12.4, mean ± standard deviation) and reported symptoms at a younger age (23.3 ± 10.8 vs. 26.2 ± 11.1), but their time to first consultation was longer than for White patients (2.6 ± 5.7 vs. 1.2 ± 2.5 years). People from racial and ethnic minority groups took longer to receive a correct diagnosis following first consultation (2.7 ± 5.3 vs. 1.5 ± 4.1 years) and were more likely to be misdiagnosed with boils (73.5% vs. 40.4%). People from racial and ethnic minority groups had a greater disease awareness at diagnosis and reported wanting greater support. People from racial and ethnic minority groups reported a greater impact on life, more severe pain, and a greater level of activity impairment in the Work Productivity and Activity Impairment: General Health (27.0 ± 25.2 vs. 20.0 ± 20.6). All P values were ≤0.05. These data show evidence of delayed diagnosis and higher HS symptom burden amongst people from racial and ethnic minority groups, highlighting health disparities in HS.
