    Abstract:
    INTRODUCTION: We aim to evaluate the association of early versus late venous thromboembolism (VTE) prophylaxis on in-hospital mortality among patients with severe blunt isolated traumatic brain injuries. METHODS: Data from the American College of Surgeons Trauma Quality Program Participant Use File for 2017-2021 were analyzed. The target population included adult trauma patients with severe isolated traumatic brain injury (TBI). VTE prophylaxis types (low molecular weight heparin and unfractionated heparin) and their administration timing were analyzed in relation to in-hospital complications and mortality. RESULTS: The study comprised 3609 patients, predominantly Caucasian males, with an average age of 48.5 y. Early VTE prophylaxis recipients were younger (P < 0.01) and more likely to receive unfractionated heparin (P < 0.01). VTE prophylaxis later than 24 h was associated with a higher average injury severity score and longer intensive care unit stays (P < 0.01). Logistic regression revealed that VTE prophylaxis later than 24 h was associated with significant reduction of in-hospital mortality by 38% (odds ratio 0.62, 95% confidence interval 0.40-0.94, P = 0.02). Additionally, low molecular weight heparin use was associated with decreased mortality odds by 30% (odds ratio 0.70, 95% confidence interval 0.55-0.89, P < 0.01). CONCLUSIONS: VTE prophylaxis later than 24 h is associated with a reduced risk of in-hospital mortality in patients with severe isolated blunt TBI, as opposed to VTE prophylaxis within 24 h. These findings suggest the need for timely and appropriate VTE prophylaxis in TBI care, highlighting the critical need for a comprehensive assessment and further research concerning the safety and effectiveness of VTE prophylaxis in these patient populations.
