Teledermatology May Benefit Marginalized Populations: National and Institutional Trends during the COVID-19 Pandemic.

INTRODUCTION: Limited data exist regarding demographic-specific teledermatology (TD) utilization during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to determine TD utilization trends during the pandemic. METHODS: A retrospective cohort study for national and institutional populations was conducted. Patient encounters in the American Academy of Dermatology's DataDerm registry (DataDerm) were analyzed from 1 April 2020 through 30 June 2021. All dermatological patients seen by Duke University Health Systems (DUHS) were analyzed from 1 March 2020 through 30 April 2021. In-person clinic visits versus TD encounters (national and institutional) and no-show rates (institutional only) were collected for visit type (i.e., TD versus in-person), sex, race, age/generation, and in- versus out-of-state location (national only). TD utilization is defined as the cohort of interest using TD (e.g., females, whites) within a demographic group (i.e., sex, race) as a percentage of total TD users. This was compared with in-person utilization during the identical timeframe. RESULTS: For US national data, 13,964,816 encounters were analyzed. Sex, race, age, and location each had a significant association with TD utilization (adjusted p < 0.001). For institutional data, 54,400 encounters were analyzed. Sex, race, and age had a significant association with TD utilization (adjusted p < 0.001). Both datasets revealed majority female populations for telehealth visits (DataDerm 66.0%; DUHS 61.7%). Non-white populations accounted for a higher percentage of TD utilizers (DataDerm 15.0%; DUHS 37.3%) when compared with in-person utilizers (DataDerm 11.7%; DUHS 22.3%). Younger patients utilized TD (DataDerm 63.6%; DUHS 62.6%) more than in-person services (DataDerm 26.3%; DUHS 43.8%). Institutional no-show rates between telehealth and in-person visits were lower for Black patients (11.8% versus 19.2%), other non-white races (10.6% versus 13.6%), and younger ages/generations (9.8% versus 12.8%), respectively. TD utilization decreased over time nationally as a percentage of total visits (2.9% versus 0.3%) in 2020 versus 2021, respectively. CONCLUSIONS AND RELEVANCE: During the COVID-19 pandemic, certain populations (females, younger patients, non-white races) showed higher TD utilization. Understanding TD utilization trends is critical in defining the role of virtual care for improving universal care access, optimizing resources, and informing future healthcare models for all patient populations.
