Pharmacoeconomic Analysis of Bemiparin and Enoxaparin as Prophylaxis for Venous Thromboembolism in Total Knee Replacement Surgery
Introduction: Low molecular weight heparins are effective and have a good tolerability profile as first-line prophylaxis for venous thromboembolism (VTE) in major orthopaedic surgery. However, pharmacological inequivalence within the class could lead to differences in cost-effectiveness ratios. Objective: To quantify the potential economic impact of subcutaneous bemiparin sodium 3500 IU/day compared with enoxaparin sodium 40 mg/day as prophylaxis for VTE in patients undergoing total knee replacement (TKR) surgery, considering both in-hospital and post-discharge outcomes and costs during 6 weeks of postoperative follow-up. Methods: A cost-effectiveness analysis was performed using a decision modelling approach. The results were expressed in terms of costs and incremental cost effectiveness in Results: Bemiparin provided cost savings of Conclusions: Our model suggests, based on its underlying assumptions and data, that bemiparin may be more cost effective than enoxaparin for thromboprophylaxis in total knee replacement surgery in the Spanish healthcare setting.
