Background: Alcoholism is associated with variable effects on the coagulation system. Therefore, the aim of our study was to analyze the currently unknown association between chronic alcohol consumption and the risk of venous thromboembolism, which includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Methods: We performed a 2-y (2013-2014) analysis of the American College of Surgeons Trauma Quality Improvement Program database. All trauma patients with an Injury Severity Score (ISS) > 16 were included. We excluded patients with acute alcohol intoxication, hematologic disorders, and cancer. Patients were divided into two groups (alcoholic and nonalcoholic) and were matched using propensity score matching (1:1) for demographics, ISS, injury location, and admission vitals. Outcomes measures were the prevalence of venous thromboembolism in each group. Results: Of the 91,066 trauma patients included in our analysis, 35,460 patients were matched (alcoholics: 17,730; nonalcoholics: 17,730). The mean was age 45 ± 18 y, and 81% were males. Matched groups were similar in age (P = 0.32), heart rate (P = 0.31), systolic blood pressure (P = 0.46), location of injury (P = 0.85), ISS (P = 0.76), and Glasgow Coma Scale (P = 0.38). Prevalence of DVT was lower in alcoholics compared with nonalcoholics (2.34% versus 5.12%, P = 0.01). The overall incidence of PE was 1.2%, and there was no difference between the two groups (1.1% versus 1.3%, P = 0.22). Similarly, there was no difference in mortality (14.8% versus 15.4%, P = 0.32) between the groups. Conclusions: Chronic alcohol consumption is associated with a low risk of DVT in trauma patients. This association warrants further investigation of the possible physiological effects of alcohol in trauma patients. Level of evidence: Level III Prognostic.
