Barriers to Remote Burn Care Delivery: An Analysis of Burn Center Proximity and Access to Critical Telehealth Infrastructure.

Mounting evidence supports the use of telehealth to improve burn care access and efficiency. However, barriers to telehealth use remain throughout the United States and may disproportionately affect specific populations, such as rural and non-English-speaking patients. This study analyzes the association between physical proximity to burn care and determinants of telehealth access.The relationship between telehealth-associated measures and proximity to burn care was analyzed with linear regression analysis. County-level data was sourced from the Agency for Healthcare Research and Quality's Social Determinants of Health Database (2020) and the American Community Survey (2021). County-level distances to the nearest American Burn Association (ABA)-verified burn center were calculated based on verified centers listed in the ABA burn center directory (n = 59). A subsequent analysis was performed on income-stratified datasets available for subset counties.Distance was negatively correlated with access to a smartphone (P < 0.0001), broadband internet (P < 0.0001), and cellular data plan (P < 0.0001) and positively correlated with the percent of households with no computing device (P < 0.0001) and no internet access (P < 0.0001). Analysis of income-stratified data revealed similar results. The percent population not speaking English well (P < 0.0001) at all (P = 0.0009) and the proportion of limited English-speaking households (P = 0.0001) decreased as a function of distance.People living furthest from an ABA-verified burn center in the United States are less likely to have adequate access to critical telehealth infrastructure compared to their counterparts living closer to a burn center. However, income impacts overall access and the degree to which access changes with proximity. Conversely, language-associated barriers decrease as distance increases.
