The influence of socioeconomic status on management and outcomes in major trauma: A systematic review and meta-analysis.

Abstract

Background: Major trauma is a leading cause of death and disability in younger individuals and poses a significant public health concern. There is a growing interest in understanding the complex relationships between socioeconomic deprivation and major trauma. Anecdotal evidence suggests that deprivation is associated with more violent and debilitating injuries. There remains a paucity in literature evaluating major trauma outcomes in relation to socioeconomic deprivation.

Methods: A comprehensive search of MEDLINE, Embase, and CENTRAL databases was performed to identify studies from 1947 to March 2024. The primary outcome was to establish the distribution of injuries based on deprivation, with secondary outcomes evaluating surgical intervention rates, length of stay, and mortality. Quantitative pooling of data was based on the random-effects model.

Results: Fourteen studies and 878,872 trauma patients were included. A substantial proportion (28%) of trauma incidents occurred in the most deprived group. Patients from the lowest socioeconomic group were considerably younger (weighted mean difference [WMD] -9.85 years and 95% confidence intervals [CI] -9.99 to -9.70) and more likely to be male (odds ratio [OR] 1.36 and 95% CI 1.14-1.63). There were no differences in surgical intervention (OR 1.74 and 95% CI 0.97-3.13), length of stay (WMD 1.15 days and 95% CI -0.32-2.62), and mortality (OR 1.04 and 95% CI 0.95-1.14) regardless of background.

Conclusion: Major trauma is prevalent in deprived areas and in younger individuals, with an increasing trend of deprivation in male patients. Although the rates of surgery, length of stay, and mortality did not differ between groups, planning of public health interventions should target areas of higher deprivation.
