Impact of Pharmacists' Training on Oral Anticoagulant Counseling
Deep Vein ThrombosisPulmonary Embolism1 moreThis study evaluates the impact of community pharmacists' educational training on the nature and adequacy of counseling provided to patients on warfarin, an oral anticoagulant. Half of the community pharmacists participating in the study will receive a two-week educational training on how to adequately counsel patients on warfarin while the other half of community pharmacists will receive the same training after the study. A mystery patient model will be used in this intervention study where six different trained and standardized individuals will act as patients. Each of these mystery patients will supposedly have pulmonary embolism, deep vein thrombosis, or atrial fibrillation. The mystery patient will visit each pharmacy to buy warfarin or complain about adverse drug reaction been experienced. It is expected that pharmacists will provide relevant information and counseling to these patients on the use of the medication warfarin and how to handle the adverse drug reactions.
Functional Training for the Prevention of Deep Venous Thrombosis
Ankle MotionGynecologic Neoplasm2 moreThis study aims to analyze the post-operative functional training on the prevention of deep venous thrombosis (DVT) in the patients who have accepted major surgeries for the gynecological malignancies. The functional training consists of: (1) active and passive ankle pump motions including flexion and extension, circumduction; (2) abdominal breathing training. The primary end is the incidence of DVT happened 30 days from surgery. The secondary ends include the patients satisfaction about functional training.
Inferior Vena Cava Filters: Analysis of a Database
Deep Vein ThrombosisPulmonary EmbolusIn this study a retrospective analysis of patients database was performed, who underwent treatment for deep vein thrombosis in tertiary hospital by using inferior vena cava-filters
Ancillary Study of the ULTREC Project
Deep Vein ThrombosisThe ULTREC research project is designed to assess the safety of a negative strategy relying on Colour Doppler Ultrasound (CDUS) for excluding the diagnosis of a new thrombosis. The ULTREC project does not take into account the validity of the CDUS positive criteria used to confirm the diagnosis of Deep Vein Thrombosis (DVT) recurrence. The risk of considering only the negative strategy is to ignore the possibility of having an improvement in sensitivity and negative predictive value at the expense of specificity and positive predictive value and therefore to increase the false positive rate leading to an overdiagnosis of recurrence and an overtreatment, and a potential bleeding risk. In the ULTREC-ANCILLARY study, the research will aim at assessing the validity of baseline CDUS positive criteria for the diagnosis of DVT recurrence. As there is no diagnostic standard to which the results could be compared, it is suggested to validate these criteria based on the evolution of the thrombosis on CDUS performed at D90±5. The hypothesis is that an unchanged appearance under anticoagulation would be in favor of sequelae and will invalidate the initial diagnosis (diagnostic failure)
D-dimer and Pre-test Clinical Probability Score in Cancer Patients With Suspected Deep Vein Thrombosis...
Deep Vein ThrombosisPatients with cancer have a high risk of deep vein thrombosis which often develops in the veins of the lower limbs. The initial evaluation of clinically suspected deep vein thrombosis includes the estimation of the clinical probability by calculating risk scores such as the Wells score and the measurement of the D-dimer. However, the usefulness and accuracy of the clinical scores and d-dimer test are lower in patients with cancer who often undergo unnecessary (serial) ultrasonography. The aim of the current study is to analyze variables that predict the presence of thrombosis and may improve the accuracy of the Wells score. In addition, various cut-off of the d-dimer will be evaluated with the goal of improving the sensibility and specificity of the test.
The Designer D-dimer Deep Vein Thrombosis Diagnosis (4D) Study
Suspected Deep Vein ThrombosisThis is a cohort study that will assess a new diagnostic management strategy for suspected Deep Vein Thrombosis in outpatients.The new diagnostic strategy is designed to reduce the use of ultrasound testing on the day of presentation, and reduce repeat ultrasound testing a week after an initial normal test.
Utilization of TEG to Monitor Rivaroxaban Activity
AnemiaVenous ThrombosisThe invesigators seek to devise a strategy for the assessment of Rivaroxaban activity in trauma and Emergency General Surgery (EGS) patients available as point-of-care testing. Thromboelastography (TEG) is a point of care, viscoelastic measurement of coagulation that is widely used in trauma and is viewed by many as superior to standard coagulation studies for the assessment of coagulopathy following injury and may be useful in detecting rivaroxaban effect in trauma and EGS patients to assess the degree of functional factor Xa impairment.
Study of the Bioaccumulation of Tinzaparin in Renally Impaired Patients When Given at Prophylactic...
Renal InsufficiencyChronic2 moreThe purpose of this study is to assess if accumulation of anti-Xa activity occurs after repeated daily administration of prophylactic doses of tinzaparin in patients with severe chronic kidney disease (CKD) requiring thromboprophylaxis for non-surgical conditions. It is anticipated that tinzaparin used at a fixed dose for thromboprophylaxis in severe CKD patients (eGFR ≤ 30 ml/min /1.73 m2) at risk for venous thromboembolism (VTE) will not bioaccumulate at a significant level, meaning an increase of ≥ 20% of the anti-Xa mean level between day 2 or 3 and day 5.
Modelling Interface Pressure Applied by Superimposed Compression Bandages
Risk of Venous ThrombosisThe aim of the study is to measure and model interface pressure applied on the lower leg of patients at risk of veinous thrombosis, by different bandage combinations, composed of Biflex 16 (Thuasne) and/or Rosidal K (Lohmann & Rauscher). The patient specific model should better predict the interface pressure distribution than Laplace's Law.
