Abstract

Purpose

Studies in non-trauma populations have shown that Black patients have a higher risk of venous thromboembolism (VTE) compared to other races. We sought to determine whether this association exists in trauma patients. The incidence of VTE is particularly high following severe pelvic fractures. To limit confounding factors associated with additional injuries, we examined patients with isolated blunt severe pelvic fractures.

Methods

The TQIP database (2013–2017) was queried for all patients who sustained isolated blunt severe pelvic fractures (AIS ≥ 3) and received VTE prophylaxis (VTEp) with either unfractionated heparin or low molecular weight heparin. The study groups were Asian, Black, and White race as defined by TQIP. The primary outcome was differences in the rate of thromboembolic events.

Results

A total of 9491 patients were included in the study. Of these, 232 (2.4%) were Asian, 1238 (13.0%) Black, and 8021 (84.5%) White. There was no significant difference in the distribution of pelvis AIS 3,4,5 between the groups. Black patients had a significantly higher incidence of VTE, DVT and PE compared to Asians and Whites. After adjusting for differences between the groups, Black patients had higher odds of developing pulmonary embolism (OR 1.887, 95% CI 1.101–3.232, p = 0.021) compared to White patients.

Conclusions

In this nationwide study of trauma patients with severe pelvic fractures, Black patients were more likely to develop pulmonary embolism compared to White patients. Further research to identify the determinants of racial disparities in trauma-related VTE is warranted, to target interventions that can improve VTE outcomes for all patients.
