M. Drummond et al., ECONOMIC-EVALUATION OF STANDARD HEPARIN AND ENOXAPARIN FOR PROPHYLAXIS AGAINST DEEP-VEIN THROMBOSIS IN ELECTIVE HIP-SURGERY, British Journal of Surgery, 81(12), 1994, pp. 1742-1746
Deep vein thrombosis (DVT) is a common complication in patients underg
oing elective hip surgery. Because of the associated risk of pulmonary
embolism, prophylaxis with standard (unfractionated) heparin is becom
ing increasingly important. Recent clinical trials have shown a low mo
lecular weight form of heparin, enoxaparin, to be more effective than
standard heparin in preventing DVT, but the new drug is also more expe
nsive. Data on clinical effectiveness and cost were combined in an eco
nomic evaluation of the two regimens. It was found that prophylaxis wi
th enoxaparin would he expected to lead to a net saving of pound 20 pe
r patient. The economic results are sensitive to the costs of enoxapar
in, the costs of drug administration and the probability of false clin
ical diagnosis of DVT or pulmonary embolism.
