    BackgroundThe San Diego-Mexico border wall height extension is associated with increased traumatic injuries and related costs after wall falls. We report previous trends and a neurological injury type not previously associated with border falls: blunt cerebrovascular injuries (BCVIs).MethodsIn this retrospective cohort study, patients who presented to the UC San Diego Health Trauma Center for injuries from border wall falls from 2016 to 2021 were considered. Patients were included if they were admitted before (January 2016 to May 2018) or after (January 2020 to December 2021) the height extension period. Patient demographics, clinical data, and hospital stay data were compared.ResultsWe identified 383 patients, 51 (68.6% male; mean age, 33.5 years) in the pre-height extension cohort and 332 (77.1% male; mean age, 31.5 years) in the post-height extension cohort. There were 0 and 5 BCVIs in the pre- and post-height extension groups, respectively. BCVIs were associated with increased injury severity scores (9.16 vs. 31.33; P < 0.001), longer intensive care unit lengths of stay (median, 0 days; [interquartile range (IQR), 0-3 days]; vs. median, 5 days [IQR, 2-21 days]; P = 0.022), and increased total hospital charges (median, $163,490 [IQR, $86,578-$282,036]; vs. median, $835,260 [IQR, $171,049-$1,933,996]; P = 0.048). Poisson modeling found BCVI admissions were 0.21 (95% confidence interval, 0.07-0.41; P = 0.042) per month higher after the height extension.ConclusionsWe review the injuries correlating with the border wall extension and reveal an association with rare, potentially devastating BCVIs that were not seen before the border wall modifications. These BCVIs and associated morbidity shed light on the trauma increasingly found at the southern U.S. border, which could be informative for future infrastructure policy decisions.Copyright © 2023 Elsevier Inc.
