Summary

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common post-operative complication. The effectiveness of fondaparinux compared with other injectable anticoagulants in VTE following major orthopedic and abdominal surgery has been evaluated in database studies; however, the effectiveness of injectable anticoagulant medications following cancer-related surgeries in the practice setting has not been as well documented. The objective of this study is to analyze patient records from a national hospital database and compare the outcomes and costs between four types of injectable anticoagulant medications that were prescribed for the prevention of VTE following cancer-related surgery. This analysis will assess and quantify the outcomes, resource utilization, and cost of care for patients receiving fondaparinux, enoxaparin, dalteparin or unfractionated heparin. The outcomes of interest include the occurence of VTE, rates of major bleeds, medical resource utilization, and total costs (medical plus pharmacy). The source of data for this study is the Premier Perspective Database™. This hospital claims database links de-identified inpatient medical, pharmacy, and billing data from more than 500 hospitals. This study is a retrospective cohort study that uses propensity score matching to adjust for the differences between the numbers of patients treated with each medication.

Conditions

• Thrombosis, Venous

Interventions

Type	Name	Description
DRUG	dalteparin	An injectable anticoagulant medication for the prevention of VTE related to cancer surgery. Patients received dalteparin during one day prior to or two days after cancer-related surgery during the hospitalization.
DRUG	enoxaparin	An injectable anticoagulant medication for the prevention of VTE related to cancer surgery. Patients received enoxaparin during one day prior to or two days after cancer-related surgery during the hospitalization.
DRUG	fondaparinux	An injectable anticoagulant medication for the prevention of VTE related to cancer surgery. Patients received fondaparinux during one day prior to or two days after cancer-related surgery during the hospitalization.
DRUG	unfractionated heparin	An injectable anticoagulant medication for the prevention of VTE related to cancer surgery. Patients unfractionated heparin received during one day prior to or two days after cancer-related surgery during the hospitalization.
