A systematic scoping review of racial, ethnic, and socioeconomic health disparities in pediatric dermatology

Background/Objectives: Health disparities encompass a wide range of personal, societal, environmental, and system-based factors that contribute to inequitable health and health outcomes in vulnerable patient populations. The goal of this work was to scientifically summarize the existing published North American research on disparity as it pertains to pediatric dermatology. Methods: A systematic review was performed according to PRISMA guidelines. A medical librarian performed electronic searches from multiple electronic databases from their dates of inception to March 2021. Title and abstracts were reviewed by authors, identifying articles for full review. Data on article characteristics and identified disparities were then extracted and collected in a spreadsheet. Results: Fifty-one articles met final inclusion criteria, of which 25 highlighted disparities due to race/ethnicity, 13 highlighted disparities due to socioeconomic (SES), and 13 highlighted disparities due to both race/ethnicity and SES. The most frequent study designs were cross-sectional or survey, followed by retrospective cohort. Only two were prospective cohort studies. Disparities reported included reduced access to care and medications, increased school absenteeism, reduced knowledge about skin care including sun protection, increased hospitalizations and emergency department visits, and severe and persistent disease in the setting of minority race and poverty, among other indicators. Conclusions: There are few, scattered research studies addressing disparity in pediatric dermatology. Greater focus will be needed in the future to improve knowledge of sources of disparity and its detrimental effects on the health of children, to rectify the notable disparity under-reporting of disparity research.
