Enoxaparin. A pharmacoeconomic appraisal of its use in thromboembolic prophylaxis after total hip arthroplasty.
Total hip arthroplasty (THA) is a major orthopaedic procedure with a high risk of postoperative thromboembolism. Increasing demand for this type of surgery, together with its high cost, has led to examination of means by which the cost of THA may be minimised. Current clinical opinion favours the use of suitable pharmacological thromboprophylaxis in patients undergoing THA; such prophylaxis may be provided with subcutaneous standard unfractionated heparin (UFH), oral warfarin or subcutaneous low molecular weight heparin (LMWH). ⋯ It has also been suggested that the use of once- or twice-daily enoxaparin in preference to UFH may reduce the overall length of hospital stay; a significant difference emerged in 1 analysis (9.9 or 9.5 vs 11.3 days). Pharmacoeconomic data therefore support the use of enoxaparin as an effective thromboprophylactic treatment with potential cost advantages over warfarin and UFH. Cost-effecti
