ARIXTRA® Adherence in SVT Patients.

ARIXTRA® Physician Adherence to the Prescribing Information in Isolated Superficial Vein Thrombosis (SVT) Patients.

Fondaparinux is an anticoagulant used in the prevention and treatment of thromboembolic disease. It has recently been approved in the European Union (EU) for the treatment of patients with isolated superficial vein thrombosis (SVT), i.e. without concomitant deep vein thrombosis (DVT), of the lower limbs. As part of EU approval, GlaxoSmithKline (GSK) committed to evaluate physicians' adherence to fondaparinux prescribing information regarding proper diagnosis and dosing for the treatment of SVT.

The primary objective is to evaluate physicians' adherence to fondaparinux prescribing information for the treatment of patients with SVT without concomitant DVT.

The study is designed as a non-interventional, retrospective chart review of patients prescribed fondaparinux to treat their SVT. The study will be conducted in several EU countries.
