OBJECTIVES: To evaluate the direct costs of venous thromboembolism (VTE) treatment with unfractionated heparin (UFH) and low-molecular weight heparin, from the institutional perspective. METHODS: This is a real-world cohort study that included inpatients treated with UFH or enoxaparin for deep venous thromboembolism or pulmonary embolism in a tertiary public hospital. To estimate medical costs we computed the acquisition costs of drugs, supplies for administration, laboratory tests, and hospitalization cost according to the patient ward. RESULTS: One hundred sixty-seven patients aged 18 to 92 years were studied (50 treated with UFH and 117 with enoxaparin). The median of days in use of heparin was the same in both groups. Activated partial thromboplastin time was monitored in 98% of patients using UFH and 56.4% using enoxaparin. Nonstatistically significant differences were observed between groups in the number of bleeding events (10.0% and 9.4%; P = 1.00); blood transfusion (2.0% and 2.6%; P = 1.00); death (8.0% and 3.4%; P = 0.24); and recurrent VTE, bleeding, or death (20.0% and 14.5%; P = 0.38). Daily mean cost per patient was US$12.63 ± $4.01 for UFH and US$9.87 ± $2.44 for enoxaparin (P < 0.001). The total costs considering the mean time of use were US$88.39 and US$69.11. CONCLUSION: The treatment of VTE with enoxaparin provided cost savings in a large teaching hospital located in southern Brazil.
