Abstract
BACKGROUND: The aim of this study was to compare the efficacy and tolerability of enoxaparin for preventing thromboembolism after surgery in the out-patient and in-hospital settings. MATERIALS AND METHODS: A total of 2,005 out-patient and 1,360 hospitalized patients were included in the study. Prophylaxis was carried out with 20 or 40 mg enoxaparin and follow-up examination after 4-6 weeks. RESULTS: Out-patients were younger (mean 48.4 vs. 58.5 years, p<0.01), had less cardiovascular comorbid diseases (7.1 vs. 20.8%, p<0.01) and underwent less complex interventions (arthroscopy 33.6 vs. 7.5%, p<0.01). Out-patients also received 20 instead of 40 mg enoxaparin more frequently (60.7 vs. 38.3%, p<0.01). The mean duration of thromboprophylaxis was reduced (12.6 vs. 15.3 days). For patients treated with 20 and 40 mg minor bleeding was observed in 1.8 and 3.4%, respectively (4.7 with 20 mg and 4.5% with 40 mg in hospital), major bleeding was 0.1% for both doses in out-patients and 0.0% with 20 mg and 0.3% with 40 mg in-hospital. Deep vein thrombosis (DVT) occurred in 0.4% of out-patients receiving 20 mg enoxaparin and 0.6% with 40 mg (0.0% with 20 mg and 0.9% with 40 mg in-hospital). There were no cases of pulmonary embolism (PE) in out-patients but PE was observed in 0.2% and 0.5% with 20 mg and 40 mg in-hospital patients, respectively. CONCLUSIONS: Thromboprophylaxis with enoxaparin is well tolerated under clinical conditions as well as under out-patient treatment and severe bleeding complications are rare.
