Deep venous thrombosis prophylaxis in trauma: cost analysis.
Deep vein thrombosis and pulmonary embolism are major risks in patients experiencing major trauma. Currently, the American College of Chest Physicians recommends low molecular weight heparin as prophylaxis in trauma patients with identifiable risk factors in the absence of contraindications. Enoxaparin is the only low molecular weight heparin available in the US that has been evaluated to date in this indication. The purpose of this study was to perform incremental cost-effectiveness ratio calculations for enoxaparin versus no prophylaxis as thromboembolic prophylaxis in trauma patients. These calculations demonstrate that a cost of $279.43 would be incurred for each thromboembolic event avoided if enoxaparin 30 mg every 12 h were routinely used as prophylaxis in this population, compared with no prophylaxis. Sensitivity analyses demonstrate that if the incidence of proximal vein thrombosis in patients prophylaxed with enoxaparin approached 1.8%, if the actual rate of these thrombi exceeded 19.4% in untreated patients, or if the cost of the drug was decreased to $15.25 per dose, a cost saving would be experienced in routine prophylaxis with this agent.
