The impact of the Mexico–San Diego border wall extension on spine injuries: a retrospective cohort review

Abstract

Background

The recent San Diego–Mexico border wall height extension has resulted in an increased injury risk for unauthorized immigrants falling from greater heights. However, the effects of the border wall extension on frequency and morbidity of spinal injuries and related economic costs have yet to be highlighted.

Methods

We retrospectively compared two cohorts who presented to the UC San Diego Health Trauma Center for border wall falls: pre-height extension (12 patients; January 2016–May 2018), and post-height extension (102 patients; January 2020–December 2021). Patients presented during border wall construction (June 2018–December 2019) were excluded. Demographics, clinical data and hospital costs were collected. Spinal injuries were normalized using Customs and Border Protection apprehensions. Costs were adjusted for inflation using the 2021 medical care price index.

Results

The increase in spine injuries per month (0.8–4.25) and operative spine injuries per month (0.3– 1.7) was statistically significant (P < 0.001). Increase in median length of stay from 6 [interquartile range (IQR) 2–7] to 9 days (IQR 6–13) was statistically significant (P = 0.006). Median total hospital charges increased from $174 660 to $294 421 and was also significant (P < 0.001).

Conclusion

The data support that the recent San Diego–Mexico border wall extension is correlated with more frequent, severe and costly spinal injuries. This current infrastructure should be re-evaluated as border-related injuries represent a humanitarian and public health crisis.
