Study Summary

The rates of Venous thromboembolism (VTE) after orthopedic surgery are as high as 40-60% without prophylactic measures. Enoxaparin, a low-molecular-weight heparin, produces an anticoagulant effect by binding antithrombin, thereby accelerating antithrombin's inactivation of coagulation factor Xa (FXa), thus decreasing the likelihood of clot formation. Despite standard dosing enoxaparin prophylaxis, VTE rates in post-operative orthopedic trauma patients remain as high as 12.2%.The investigators will examine enoxaparin pharmacokinetics and test whether a clinical protocol for real-time enoxaparin dose adjustment can favorably alter the proportion of patients with in-range anti-Factor Xa (aFXa) levels. Outcomes will include peak and trough steady-state aFXa levels in response to standard and escalated doses of enoxaparin and the incidence of venous thromboembolism and bleeding events post-surgery. In the trauma and orthopaedic populations, patients with low initial aFXa levels are significantly more likely to develop deep venous thrombosis. Thus, this study has important implications for appropriate enoxaparin dose magnitude and frequency, and may ultimately help to decrease the substantial morbidity and mortality associated with post-operative VTE.
