Filter by:An investigator initiated study exploring VTE prophylaxis at the time of hospital discharge.
This study will evaluate if extended therapy with oral rivaroxaban can prevent blood clots in the leg and lung that can occur with patients hospitalized for acute medical illness, and compare these results with those of the standard enoxaparin dose and duration regimen. The safety of rivaroxaban will also be studied.
The primary efficacy objective is to evaluate whether dabigatran etexilate is superior to placebo in the long-term prevention of recurrent symptomatic venous thrombo-embolism (VTE) in patients with symptomatic deep-vein thrombosis (DVT) or pulmonary embolism (PE) who completed 6 to 18 months of treatment with vitamin K antagonist (VKA).
This study was designed to assess the safety of retrieval of the Bard Recovery® G2® Filter System. The G2 filter is an FDA-cleared device for inferior vena caval interruption in patients with pulmonary thromboembolism.
Fondaparinux is an antithrombotic agent having already received a regulatory approval by the European Authorities in venous thromboembolic event prevention after major orthopaedic surgery, as total hip replacement (THR), total knee replacement (TKR), hip fracture (HF). The bleeding risk associated with this prescription is highly related to renal function evaluated by creatinin clearance (CrCl). In order to reduce the bleeding risk, it has been proposed to prescribe fondaparinux 1.5 mg/day in patients with a CrCl between 20 and 50ml/mn instead of 2.5mg/day (European MMA). In the meantime, this approval is essentially based on simulated pharmakinetic data without any support of clinical data. prospective, multicentre, open-label study evaluating the safety profile of fondaparinux 1.5 mg/day, subcutaneously administered, in patients with a renal impairment defined by a CrCl between 20 and 30 ml/min and undergoing a major orthopaedic surgery.
To determine the effect of an interventional campaign run by a dedicated "VTE Nurse Educator" over a 6-month period and the effect on prophylaxis rates. To determine the proportion of medically admitted patients with risk factors for VTE. To assess and compare the use of venous thromboembolism (VTE) prophylaxis in hospitalized medical patients versus recommendations and current guidelines. To determine the patient characteristics of those deemed to be at risk of VTE. To determine the proportion of patients receiving appropriate thromboprophylaxis for their risk. To determine the type and duration (where possible) of prophylaxis used.
Trauma patients are at high risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE). The incidence of DVT varies greatly from 5-63% among studies depending on patient's individual risk factors, modality of prophylaxis, and methods of detection. The incidence of PE may be as low (0.3-4.3%) but carries a mortality of 20-50% which makes prevention of DVT of the utmost importance. The current standard of care for DVT prophylaxis in the trauma patient with high risk of DVT is enoxaparin, a low molecular weight heparin, administered twice a day as long as anticoagulation in not contraindicated. Many studies have demonstrated its efficacy when compared to mechanical compression and to unfractionated heparin, however one of the most robust of these studies still reported an DVT incidence of 35% in patients treated with enoxaparin. Another drug, fondaparinux, is a selective factor Xa inhibitor that could offer added benefits over enoxaparin such as once daily dosing and a drastically reduced risk of heparin induced thrombocytopenia (HIT). Fondaparinux has been already be widely used in post-operative hip surgery and major knee surgery patients with good results. It has also been shown to be effective in DVT prophylaxis in patients who have had major abdominal surgery and also in acute medical patients. Fondaparinux has yet to be used in trauma patients. Trauma patients are a diverse and distinct population given the acuity of their injuries and their increased risk of bleeding who at this time still do not have a perfect method for DVT prophylaxis. We hypothesize that fondaparinux will be effective in decreasing the risk of DVT when used in the trauma patient population. This is a non randomized prospective cohort study designed to test the efficacy of fondaparinux in the prophylaxis of DVT and PE in trauma patients.
The objective of this study is to compare the risk of venous thromboembolism (VTE) of oral contraceptives with non-use, focusing specifically on Valette® compared to other users of low estrogen dose combined oral contraceptives.
This study uses the PharMetrics and MarketScan US health care insurance claims database to estimate relative risks for non-fatal venous thromboembolism (including cerebral venous sinus thrombosis), ischemic stroke, and acute myocardial infarction (heart attack), in current users of ORTHO EVRA (norelgestromin and ethinyl estradiol contraceptive patch) compared to current users of oral levonorgestrel-containing oral contraceptives with 30 micrograms ethinyl estradiol, with special attention to duration of use.
This study is to assess the safety of a potential new drug DU-176b for the prevention of stroke/systemic embolic event (SEE) in individuals with non-valvular atrial fibrillation (AF). The duration is 3 months of treatment and a 30 day follow-up visit.
