Official title

The Comparative Effectiveness of Warfarin and New Oral Anticoagulants for the Extended Treatment of Venous Thromboembolism

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The proposed research seeks to provide insights on the contemporary epidemiology, treatment, and outcomes of VTE, including examining the uptake of new treatment strategies, the efficacy and safety of different anticoagulant options, and the impact of venous thromboembolism on patient-defined outcomes, such as quality-of-life, symptom burden, and treatment satisfaction. This information is crucial to helping clinicians and patients choose between various treatment options for venous thromboembolism in order to achieve the best possible balance between the risks, benefits, and impact on health.
