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

ABSTRACT: 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.

Access to Certified Burn Centers in the United States: The Geospatial and Transport Cost of Transfer.

Specialized burn centers are critical to minimizing burn-associated morbidity and mortality. However, American Burn Association-verified burn centers are unequally distributed across the United States, and fewer centers are available for pediatric patients relative to adults. The economic burden of transporting patients to these centers contributes significantly to the high cost of burn care. This study quantifies inequitable burn care access in the contiguous United States due to age group and location as a function of physical proximity to a verified burn center and transportation cost. County-level distances to the nearest verified adult or pediatric burn center were determined and mapped. Distance calculations for each population were combined with transport cost data (2022 CMS Ambulance Fee Schedules) to estimate transportation costs for each population (adult vs pediatric, urban vs rural). Pediatric patients reside 30.5 miles further than adults from the nearest center, significantly increasing transportation costs. Ground and air transport costs also increased for rural versus urban patients. Notably, rural patients face almost double the cost of air transport. While physical proximity to burn care appears to differ only modestly across age and region, this marginal increase in distance is associated with significant economic impact. This study highlights physical and economic barriers to burn care access faced by rural and pediatric patients and underscores the critical need to improve equity in burn care access. Future studies should expand on this report's findings to more fully characterize the additional costs associated with inequitable burn care access.
