Thrombosis Outcomes in Pediatric Venous Thromboembolism
Venous Thromboembolism'The TOP Study' is a prospective cohort study whose main objective is to develop better prognostic biomarkers and identify children at risk of adverse thrombotic outcomes very early in the course after an initial venous thromboembolic events (VTE). The study will compare biomarkers in children that develop poor VTE outcomes (such as recurrence, postthrombotic syndrome and post PE impairment ) after an initial VTE with those that do not develop such outcomes.

Delayed Versus Early Enoxaparin Prophylaxis After Traumatic Brain Injury (TBI)
Venous ThromboembolismTraumatic Brain InjuryBrain injured patients are at high risk for forming blood clots in the legs and lungs. For non-brain injured trauma patients, we decrease the chances of these blood clots forming by placing the patients on a low dose of the blood thinner enoxaparin. Starting patients with a brain injury on the blood thinner is problematic, however, as this can theoretically cause the brain injury to worsen. Trauma surgeons wait a variable period of time before starting this blood thinner because waiting too long can result in the formation of these blood clots in the legs and lungs. Previous research has shown that some brain injuries which are of lower severity can have enoxaparin started at 24 hours after injury if the brain injury is stable on a repeated computed tomography (CT) scan of the head. This is a pilot study designed to look at the rates of worsening of brain injury if the low dose blood thinner is started at 24 versus 96 hours post-injury.

Oral Anticoagulant Apixaban for Treatment of Venous Thromboembolism

Education Bundle to Decrease Patient Refusal of VTE Prophylaxis
Venous ThromboembolismDeep Venous Thrombosis1 moreThe investigators have recently developed a registry of missed doses of VTE prophylaxis that includes retrospective data on missed doses of VTE prophylaxis. To decrease rates of VTE prophylaxis refusal, the group has developed a patient-centered education bundle that will be delivered as an in-person, 1-on-1 discussion session with a nurse educator. Supporting education materials include a 2-page education sheet and an educational video. The investigators hypothesize that patient refusal of VTE prophylaxis is associated with significant knowledge gaps among patients regarding patients' risk of developing VTE and the benefits of VTE prophylaxis and that delivering an education bundle to patients that refuse VTE prophylaxis will improve compliance with VTE prophylaxis and decrease rates of VTE.

Prolonged Anticoagulation After a First Episod of Idiopathic Proximal Deep Vein Thrombosis (PADIS...
Recurrent Venous ThromboembolismIdiopathic Deep Vein ThrombosisIn a French multicenter double blind randomized controlled trial, the main objective is to demonstrate that, after 6 months of oral anticoagulation for a first episode of idiopathic proximal deep vein thrombosis, 18 months of warfarin therapy is associated with a lower cumulative risk of recurrent VTE and major bleeding in comparison with that on 18 months of placebo. The secondary objectives are: (1) to determine the risk of recurrent VTE after 6 months of warfarin therapy and the presence or the absence of residual lung scan perfusion defect and the persistence or not of elevated D-dimer test; and (2), to determine the impact of extended duration of anticoagulation on the risk of VTE after stopping anticoagulant therapy on a follow-up of 2 years.

Venous ThromboembolismVenous Thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is associated with an increase in risk of mortality and long-term disability and is a major contributor to global disease burden. Participants hospitalized with an acute medical illness are at increased risk of VTE. This study a non-interventional study which analyzes data already collected in the Optum US clinical database. Its aim is to compare conventional versus extended duration prophylaxis with enoxaparin on the incidence of VTE and bleeding events in participants hospitalized for acute medical illness. The first date of enoxaparin treatment will be the index date.
RIPT Feasibility Trial
Pulmonary EmbolismTrauma1 moreThe risk of venous thromboembolism (VTE) is very high in trauma patients, secondary to tissue injury, venous status from immobilization, and thrombophilia. As such, early initiation of VTE prophylaxis is essential in this population. The competing risks of life threatening hemorrhage and VTE need to be considered very carefully. Potential approaches to VTE prophylaxis include pharmacologic means, and mechanical devices. For patients unable to receive pharmacologic VTE prophylaxis, retrievable inferior vena cava filters (rIVCFs) may be placed until low molecular weight heparin (LMWH) can be initiated, as per guidelines such as Eastern Association for the Surgery of Trauma The investigators propose a feasibility study to determine whether or not our center can insert rIVCFs in at-risk trauma patients expeditiously enough to cause a meaningful reduction in the time they are left unprotected to PE.
