Overview Of Care For Hidradenitis Suppurativa In The Unified Health System: A National Epidemiological Approach

Abstract This retrospective epidemiological study analyzed 83,220 Hidradenitis Suppurativa (HS)-related outpatient procedures in Brazil (2020–2024) using Department of Informatics of the Brazilian Unified Health System (DATASUS) public health data to identify demographic and geographic disparities. Females comprised 62.5% of cases, with peak occurrence among ages 21–30 (33,251 cases). Racial inequities emerged: White and 'pardos' individuals represented 54.9% of cases versus 7.9% Black and 0.01% Indigenous patients, discordant with Brazil’s majority Black/mixed-race population. Geospatial analysis revealed clusters in Ceará, Distrito Federal, and Paraná (10–15 procedures/100,000), contrasting with underreporting in Northern states (e.g., Roraima: 1–5/100,000). A 40% national rise in HS procedures over five years highlights urban-centric diagnostic trends. These findings suggest systemic barriers in healthcare access, emphasizing the need for equity-focused policies, including dermatologist training in underserved regions and HS awareness campaigns.
