Epidemiology of Venous Thromboembolism

Venous ThromboembolismPulmonary Embolism3 more

More than 5 years ago the DVT FREE Registry was conceived. Its database consists of 5,451 ultrasound-confirmed DVT patients from 183 institutions. This database is rich in information of critical importance to health care providers. The information contained within the database will be revisited to provide more detailed analyses which will be used for risk factor assessment and for decision-making regarding the implementation of VTE Prophylaxis.

Risk Factors for Recurrence of Thrombosis or Thrombotic Extension, in the Event of Acute Non-cirrhotic...

Portal Vein ThrombosisLocal Cause

In case of acute portal vein thrombosis (PVT) prothrombotic factors are identified in about 60% of cases, while a local condition is present in 30% of cases. Prothrombotic factors may indicate a long term anticoagulant therapy whereas the risk of recurrence seems low when a local condition is isolated (cholecystitis, angiocholitis, liver abces, diverticulitis, appendicitis, acute/chronic pancreatitis, chronic bowel inflammatory disease, acute hepatitis due to cytomegalovirus, bacteroïdes pylephlebitis, abdominal neoplasia such as adenocarcinoma of the colon, abdominal traumatism or surgery such as cholecystectomy, bariatric surgery or splenectomy). To date the impact of prothrombotic factors associated with local conditions responsible for acute PVT has not been well studied except for acute or chronic pancreatitis. No significant association has been pointed out in this pathology. The aim is to determine what are the risk factors of thrombotic recurrence or extension associated with local conditions responsible for acute non cirrhotic PVT, and to evaluate the rate of secondary long term anticoagulant therapy.

Satisfaction/Quality of Life With Rivaroxaban in DVT (Deep Venous Thrombosis) Indication

Venous Thrombosis

National, multicenter, prospective, observational, non-interventional study. The objective is to determine if the switch from Vitamin K antagonists (VKA) to Xarelto in subjects treated with VKA with issues in deep venous thrombosis (DVT), and prevention of recurrent DVT and pulmonary embolism (PE) is associated with an improvement of the treatment satisfaction after 3 months. The treatment satisfaction will be measured by the Anti Clot Treatment Scale (ACTS) score.

Personalized Medicine Decision-Making in a Virtual Clinical Setting

Deep Vein ThrombosisBlood Clots

Background: -How people respond to drugs depends in part on their genes. For some drugs, doctors can use an individuals genetic background to help in dosing the drug. Researchers want to know how doctors incorporate personalized or genomic medicine into clinical practice. Objective: -To study how physicians make personalized treatment decisions Eligibility: -Healthy adult primary care physicians who are internal (or family) medicine residents. Design: Participants will complete a screening form. Participants will put on a headset, called a head-mounted display, showing a virtual reality environment. The environment will contain an exam room and the virtual patient. After interacting with the virtual patient, participants will complete a series of survey measures. Participation will last for about 60 minutes. The virtual patient interaction and follow-up questions will be audio taped.

Prevalence and Predictive Factors of Portal Vein Thrombosis in Patients With Cirrhosis

Liver CirrhosisPortal Vein Thrombosis

Several studies have confirmed that patients with cirrhosis possess an imbalance in procoagulant versus anticoagulant activity due to increased factor VIII and decreased protein C. Moreover, in the last two decades there has been an increased recognition that not only bleeding but also thrombosis complicates the clinical course of cirrhosis. The prevalence and pathogenesis of portal vein thrombosis (PVT) in patients with cirrhosis without hepatocellular carcinoma are not clearly defined. The Aim of this study is to assess the prevalence of portal vein thrombosis in patients with cirrhosis without hepatocellular carcinoma, and to prospectively assess the risk factors, outcome, and prognosis in these patients. The investigators plan to enroll two hundred patients with liver cirrhosis. The patients are going to follow up for one year and evaluate at baseline and every 6 months by liver function tests, coagulation test, upper abdomen ultrasound. All relevant clinical events will be evaluated at every follow up.

ARIXTRA® Adherence in SVT Patients.

ThrombosisVenous

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. ARIXTRA® is a registered trademark of the GlaxoSmithKline group of companies.

Development of a Questionnaire to Assess Patient Knowledge About Non-vitamin K Anticoagulants (NOAC)...

Atrial FibrillationPulmonary Embolism1 more

Pharmacists are in the best position to counsel and educate patients on anticoagulant agents such as NOACs. This should enable patients to play a more active role in their treatment and ultimately enhance adherence behaviour. However, educational elements should be targeted to knowledge. Thus, the investigators will develop and validate a questionnaire that can assess knowledge about NOACs
