摘要

There are no clear recommendations for the perioperative timing and initiation of venous thromboembolism pharmacologic prophylaxis (VTEp) among polytrauma patients undergoing high-risk bleeding orthopedic operative intervention, leading to variations in VTEp administration. Our study examined the association between the timing of VTEp and VTE complications in polytrauma patients undergoing high-risk operative orthopedic interventions nationwide.A retrospective cohort study of trauma patients ≥18 years who underwent high-risk bleeding operative orthopedic interventions for pelvic, hip, and femur fractures within 24 hours of admission at American College of Surgeons (ACS) verified trauma centers using the 2019-2020 ACS-TQIP databank. We excluded patients with a competing risk of non-orthopedic surgical bleeding. We assessed operative orthopedic polytrauma patients who received VTEp within 12 hours of orthopedic surgical intervention compared to VTEp received beyond 12 hours of intervention. The primary outcome assessed was overall VTE events. Secondary outcomes were orthopedic reinterventions within 72 hours after primary orthopedic surgery, DVT, and PE rates.The study included 2,229 patients who underwent high-risk orthopedic operative intervention. The median time to VTEp initiation was 30 hours (IQR 18, 44). After adjustment for baseline patient, injury, and hospital characteristics, VTEp initiated more than 12 hours from primary orthopedic surgery was associated with increased odds of VTE (aOR 2.02; 95% CI 1.08-3.77). Earlier initiation of prophylaxis was not associated with an increased risk for surgical reintervention (HR 0.90; 95% CI 0.62-1.34).Administering VTEp within 24 hours of admission and within 12 hours of major orthopedic surgery involving the femur, pelvis, or hip demonstrated an associated decreased risk of in-hospital VTE without an accompanying elevated risk of bleeding-related orthopedic re-intervention. Clinicians should reconsider delays in initiating or withholding perioperative VTEp for stable polytrauma patients needing major orthopedic intervention.Level III, Therapeutic.
