Background (issue): Trauma centers decrease injury mortality and improve patient outcomes. We aim to utilize Geographic Information Systems (GIS) mapping to investigate the nationwide distribution of L1TCs and L2TCs in relation to population, MVC-injuries & -fatalities at the county level to determine if patients experienced faced any disparities in accessing trauma care from 2010-2018.
Methods: A cross-sectional analysis of L1TC & L2TC distribution in the United States (US) was conducted utilizing trauma center verification/designation/location data from the American Trauma Society - Trauma Information Exchange Program (ATS-TIEP), population information from the United States (US) Census Bureau, and MVC-injuries/fatalities from the National Highway Traffic Safety Administration (NHTSA) Fatality and Injury Reporting System Tool (FIRST) database from 2010-2018.
Findings: 263 L1TCs across 46 states and 156 counties and 357 L2TCs across 44 states and 255 counties were identified. The Midwest and South regions have similar quantities of L1TCs (78 vs. 77, respectively), however the Midwest contains over one-third more L2TCs in comparison (129 vs. 95). 7 counties were identified as being at-risk in the Western and Southern US regions that experienced at least a 10% increase in population size, MVC-injuries, and MVC-fatalities across from 2010-2018.
Conclusions (implications for practice): Seven US counties containing ≤2 ACSCOT-verified and/or state-designated L1TCs or L2TCs experienced a 10% increase in population, MVC-injuries, and MVC-fatalities across young adults, middle aged adults, and older adult cohorts from 2010-2018. Revision of state limitations regarding the distribution of L1TCs & L2TCs, frequent evaluation of local trauma care needs, and strategic placement of additional TCs may improve patient outcomes for heavily burdened counties.
