Large population studies in the United States have shown a prevalence of approximately 4–5%, with some studies suggesting higher prevalence. While the specific mechanism behind increased VTE incidence in the SCI population is unknown, it is likely tied to immobility and functional decline. Previous studies have also linked social determinants of health to higher VTE prevalence in certain populations. The purpose of this study is to determine the prevalence of VTE after acute SCI in the inner urban city population and to identify factors that place patients at increased VTE risk.Methods: Patients who suffered SCI between 2014 and 2019 were identified from one inner city urban hospital. A retrospective chart review was completed to record the development of VTE after SCI. Medical comorbidities, type of thromboprophylaxis used, patient demographics, injury characteristics, and postinjury sequelae were compared between individuals who did and did not develop VTE.Results: A total of 148 patients were included. These patients were from a low socioeconomic demographic when compared with the larger US population. Average household income based on zip code data for included patients was $56 647, $30 315 below the national average. The prevalence of VTE in this patient population was 19.59%. Weight, deep vein thrombosis history, chemoprophylaxis use, mobility impairment postinjury, neurologic level of SCI, malignancy history, and history of smokeless tobacco were associated with VTE (all P < .05). Low molecular weight heparin (LMWH) use was associated with fewer occurrences of VTE (P < .001).Conclusion: Patients from our urban inner city hospital have a higher VTE prevalence after SCI than shown in previous US-based studies. These patients may be at increased risk due to increased numbers of medical comorbidities, social factors, or undiagnosed medical conditions. Thromboprophylaxis with LMWH appears to lower the risk of VTE after SCI.Level of Evidence: 3.Clinical Relevance: Patients with the previously mentioned risk factors are at increased risk for VTE development during their acute recovery process. These patients should have a much lower screening threshold for VTE evaluation and likely would benefit from more routine screening to prevent complications related to VTE development or progression. Furthermore, these patients should, when medically appropriate, be treated with low molecular weight heparin for VTE prophylaxis as previously recommended by the Consortium for Spinal Cord Medicine.
