Treatment Patterns Among Patients With Venous Thromboembolism in the United States

Completed

Conditions studied: Venous Thromboembolism

In brief

The purpose of this study is to assess outpatient treatment patterns following hospitalization for venous thromboembolism (VTE). VTE is a condition that occurs when blood clot forms in the vein. This is a retrospective study (assessments on events that have already occurred) of healthcare claims from databases. The study sponsors will assess healthcare claim records of patients treated with either apixaban or warfarin. Assessment includes treatment persistence, switch, and stopping therapy, along with recurrent VTE and bleeding.
