77 Clinical Trials for Various Conditions
A systematic review and meta analysis will be performed of risk assessment models for Venous thromboembolism ("VTE" including pulmonary embolism "PE" and deep venous thrombosis "DVT")in hospitalized medical patients. The goal of this study is to evaluate whether the incidence of VTE is lower in patients that are evaluated with a risk assessment model and treated with thromboprophylaxis for their assigned level of risk.
The goal of this clinical research study is to learn if dalteparin can lower the risk of VTE occurring in the legs and lungs. This will be tested in patients with pancreatic cancer who are going to receive chemotherapy. Some patients will receive dalteparin and some will receive no study drug. The safety of dalteparin will also be studied.
Three month treatment of acute VTE with Fragmin in pediatric cancer patients
This is a prospective study with the following objectives: Primary Objective: 1. To estimate the prevalence of unsuspected VTE in oncology patients on routine staging CT scans of the thorax, abdomen and pelvis. Secondary Objectives: 2. To identify symptoms commonly associated with VTE that are present in cancer patients undergoing routine staging CT scans with findings of unsuspected VTE. 3. To identify the risk factors and demographic characteristics in outpatient cancer patients associated with the development of unsuspected VTE. 4. To determine the incidence of recurrence of new VTE in patients with unsuspected VTE at 3 and 6 months of follow-up.
Venous 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.
Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
This is a Phase 3, multicenter, open-label, blinded endpoint study to evaluate the effect of abelacimab relative to dalteparin on venous thromboembolism (VTE) recurrence and bleeding in patients with gastrointestinal (GI)/genitourinary (GU) cancer associated VTE (Magnolia)
This is a Phase 3,multicenter, randomized, open-label, blinded endpoint evaluation study comparing the effect of abelacimab relative to apixaban on venous thromboembolism (VTE) recurrence and bleeding in patients with cancer associated VTE (ASTER)
Aim to determine if aspirin 81 mg orally twice daily is effective and safe as an extended VTE chemoprophylaxis agent after major abdominal surgery for IBD patients. Study will perform an open label trial of aspirin for VTE prophylaxis compared standard of care.
This study will be a multicenter clustered randomized trial of patients in hospitals in which a universal "SMART on FHIR" platform-based EHR-embedded IMPROVE DD VTE clinical prediction rules (CPRs) with electronic order entry has been incorporated into required admission and discharge EHR workflow versus hospitals following UMC for VTE risk assessment of medically ill patients. The patient population will consist of hospitalized, medically ill (non-surgical, non-obstetrical) individuals aged \> 60 years.
This is a Phase 2 safety and tolerability trial that will take place in two parts. Part one of the trial will determine the tolerability of the OsciPulse device on healthy subjects who wear the device for up to three hours. Healthy volunteers will answer questionnaires and may undergo an ultrasound test at the end of their participation in the trial. Part two of the trial will determine the safety and tolerability of the OsciPulse device on subjects admitted to Penn Presbyterian Medical Center. Eligible subjects will be enrolled for 6 hours. In the first 3 hours, subjects will wear the standard of care intermittent pneumatic compression device or the OsciPulse device. In the second 3 hours, the subject's device will be switched and subjects will wear the alternate device not used in the first 3 hours. Subjects will answer questionnaires and may undergo an ultrasound at the end of the first 3 hours and at the end of the second 3 hours (at hour 6).
The study will evaluate the effectiveness of a novel, real-time risk prediction model for identifying pediatric patients at risk for developing in-hospital blood clots (or venous thromboembolism \[VTE\]) based on data easily extracted from the electronic medical record. The study will assess whether using the risk percentages for developing VTE derived from the model increases the number of high-risk patients screened by the pediatric hematology team, which may may lead to an overall reduction in the number of pediatric VTEs seen at Monroe Carell Jr. Children's Hospital at Vanderbilt.
This research study is attempting to answer the question of whether 81 mg aspirin once daily is as effective as 81 mg aspirin twice daily in preventing blood clots after total joint replacement surgery.
A study involving real-world database analysis to evaluate the hospital healthcare utilization and costs, and all-cause, major bleeding-, clinically relevant bleeding-, any bleeding-, and venous thromboembolism (VTE)-related hospital readmissions among hospitalized VTE patients treated with apixaban or warfarin, with or without low molecular weight heparin (LMWH)
Hospitalized medical patients have an increased risk of venous thromboembolism (VTE) across the continuum of care, including after hospital discharge. In the APEX Trial of hospitalized patients with acute medical illness, extended-duration post-discharge thromboprophylaxis with oral betrixaban reduced the frequency of asymptomatic proximal deep venous thrombosis (DVT), symptomatic proximal or distal DVT, symptomatic nonfatal pulmonary embolism (PE), or VTE-related death compared with short-duration enoxaparin. Obstacles to integration of these data in the hospitalized Medical Service patient population, including failure to identify at-risk patients, educational gaps in strategies for VTE prevention after discharge, and medication nonadherence, can be overcome with alert-based computerized decision support. This study is a single-center, 400-patient, randomized controlled trial of an EPIC Best Practice Advisory (BPA; alert-based computerized decision support tool) to increase prescription of extended-duration post-discharge thromboprophylaxis and decrease symptomatic VTE in high-risk patients hospitalized with medical illness. Specific Aim #1: To determine the impact of electronic alert-based CDS (EPIC Best Practice Advisory \[BPA\]) on prescription of extended-duration post-discharge thromboprophylaxis in high-risk patients hospitalized with medical illness who are not being prescribed any prophylactic anticoagulation for VTE prevention after discharge. Specific Aim #2: To estimate the impact of electronic alert-based CDS (EPIC BPA) on the frequency of symptomatic VTE in high-risk patients hospitalized with medical illness who are not being prescribed any prophylactic anticoagulation for VTE prevention after discharge.
VTE associated harm is underappreciated among hospitalized patients and may be associated with missed doses of VTE prophylaxis medications. In order to ensure best practices, and administer a defect-free VTE prevention nurses must understand and educate patients on the importance of the VTE prophylaxis. We propose to conduct a randomized trial comparing the effect of a validated, real-time patient education bundle (PEB), to a program of nurse feedback and coaching (NFC) provided by nurse leaders.
Aspirin and low molecular weight heparin (LMWH) are both commonly employed pharmacologic methods of venous thromboembolism (VTE) prophylaxis after orthopaedic surgery. Data comparing these two methods of VTE prophylaxis in patients undergoing pelvic/lower extremity orthopaedic surgery for malignancy are lacking, however, as compared to the data and guidelines present for VTE chemoprophylaxis after joint arthroplasty and hip fracture surgery. In this clinical trial, our specific aim is to compare the post operative incidence of VTE between patients receiving aspirin and LMWH after pelvic/lower extremity orthopaedic oncology procedures.
Venous thromboembolism (VTE) is a serious source of hospital morbidity and mortality. Chemoprophylaxis with heparin has been shown to reduce the occurrence of VTE, but it increases the risk of bleeding and it is uncomfortable to receive. For that reason, VTE prophylaxis should be reserved for patients at moderate to high risk of VTE and low risk of bleeding. However, identifying patients at low risk for VTE can be difficult, because most patients have at least one risk factor for VTE and there are no validated risk prediction tools for use in US hospitals. Instead, many hospitals have opted for a one-size-fits-all approach with near-universal prophylaxis, putting many patients at unnecessary risk of bleeding. However, to provide care that is truly patient-centered, US physicians face several challenges. First, there is no accepted risk calculator that they can use to estimate an individual patient's risk. Second, risk calculators are not readily available at the point of care. As a result, prophylaxis rates have remained stubbornly low in some institutions, while in others the rate of prophylaxis is high, but the rate of inappropriate prophylaxis is also high. This study uses a risk prediction tool developed at the Cleveland Clinic to assess an individual patient's risk of VTE. The tool is incorporated into the electronic health record in the form of a smart order set. In this randomized trial, we will assess the effects of the order set on physician behavior and patient outcomes . Examining the effectiveness of an electronic decision aid embedded in an EHR in routine clinical practice will test whether a smart order set can improve patient care by incorporating patient-specific factors into a complex decision process.
This study compares the efficacy and complication rates of early (24 hours) versus late (72 hours) VTE prophylaxis administration to TBI patients. Patients in both treatment groups will be monitored for development of VTE as well as complications from bleeding after commencement of VTE prophylaxis.
Venous thromboembolism (VTE) encompasses pulmonary embolism (PE) and deep venous thrombosis (DVT) and continues to be a major patient safety issue after reconstructive plastic surgery. Significant morbidity and mortality is associated with VTE events. This disease entity represents the most common cause of preventable in-hospital death as evidenced by over 100,000 annual VTE-related deaths in the U.S. The associated economic burden is substantial, with annual costs to the U.S. healthcare system in excess of $7 billion. Cancer patients have been identified as a particularly vulnerable patient population. Of these, breast cancer patients represent the largest group treated by plastic surgeons. An increasing number of breast reconstructions are performed in the U.S. with a documented 35% increase in the annual number of breast reconstructions since 2000. Over 106,000 breast reconstructions were performed in 2015 alone. Of all reconstructive modalities, autologous breast reconstruction using abdominal flaps is associated with the highest risk for VTE. We believe that a key element rendering these patients susceptible to postoperative VTE is inadequate duration of chemoprophylaxis. This is supported by the observation that VTE risk remains elevated for up to 12 weeks postoperatively. We hypothesize that lower extremity deep venous system stasis is a procedure-specific key contributing factor to postoperative VTE risk. This study examines the duration of postoperative lower extremity venous stasis to identify patients who might benefit from extended chemoprophylaxis. We will use Duplex imaging technology to examine the lower extremity deep venous system preoperatively, on postoperative day 1, and on the day of discharge to determine if patients display radiographic evidence of lower extremity venous stasis at the time of hospital discharge. A better understanding of pathophysiologic mechanisms that contribute to the development of VTE as well as surgical means that reduce VTE risk factors have the potential to optimize VTE prophylaxis, thus, favorably impacting clinical outcome in a large patient population.
Guideline directed use of pharmacologic Venous thromboembolism (VTE) prophylaxis emphasizes mobility evaluation. Mobility is a key component of risk stratification. Poor mobility evaluation by providers may be a significant barrier to appropriate use of VTE prophylaxis. The investigators aim is to propose to determine whether level of mobility during hospitalization is being used to influence use and duration of VTE prophylaxis among medically ill hospitalized elders. To achieve this aim, the investigator will collect prospective observational data to objectively measure inpatient mobility using patient mounted accelerometers during patient hospital stays. The investigator's goal is to improve the appropriateness of use of VTE prophylaxis among those in which the risks of harm may outweigh the benefit. Results from this study will provide important insights about use of risk assessment, and the relationship between patient mobility and VTE prophylaxis. These results are critical to understanding how to take the next steps toward improving the appropriate use and safety of anticoagulants in hospitalized older adults. Information from this study could be used in future proposals to study interventions to ultimately improve hospital practice in the care of older adults.
This is an event driven Phase 3, prospective, randomized, open-label, blinded endpoint evaluation (PROBE) parallel group study in subjects with confirmed VTE. This study is designed to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of edoxaban and to compare the efficacy and safety of edoxaban against standard of care in pediatric subjects with confirmed VTE.
The overarching objective of the study is to determine the effectiveness of LMWH/ warfarin vs. DOAC anticoagulation for preventing recurrent VTE in cancer patients. The intervention strategy is Direct Oral AntiCoagulants (DOAC) therapy with edoxaban, apixaban, rivaroxaban, or dabigatran. The comparator is low molecular weight heparin (LMWH) alone or with warfarin. The information gained will empower cancer patients and physicians to make more informed choices about anticoagulation strategies to manage VTE.
The purpose of this study is to demonstrate that rivaroxaban is superior to placebo for reducing the risk of the primary composite outcome as defined by objectively confirmed symptomatic lower extremity proximal deep vein thrombosis (DVT), asymptomatic lower extremity proximal DVT, symptomatic lower extremity distal DVT, symptomatic upper extremity DVT, symptomatic non-fatal pulmonary embolism (PE), incidental PE, and venous thromboembolism (VTE)-related death in ambulatory adult participants with various cancer types receiving systemic cancer therapy who are at high risk of developing a VTE.
The 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.
The purpose of this study is to determine if the addition of antiplatelet therapy (i.e. aspirin) to low-molecular-weight-heparin (i.e. enoxaparin) will decrease the incidence of venous thromboembolism (VTE) in high-risk critically injured patients. The investigators further aim to determine the safety and efficacy of dual thromboprophylaxis with aspirin and enoxaparin for decreasing the incidence of VTE after trauma.
This is a pilot, randomized, open-labelled study. Eligible patients will be enrolled and randomized 1:1 into "anticoagulation" arm or "anticoagulation plus atorvastatin" arm, with atorvastatin given at 40 mg orally daily for 3 months. The targeted total accrual is 80 patients, with 40 in each arm. Patients will be recruited from the hospitals and clinics at The Ohio State University Wexner Medical Center. Follow up visits are planned at enrollment, 3 months, and 9 months after randomization. At each follow up, blood will be obtained and assessments will include structured interviews of signs and symptoms of recurrent venous thromboembolism (VTE), bleeding, post thrombotic syndrome, and adverse events from study drugs.
As part of mandatory on-going nursing education, the investigators have incorporated identical information into two distinct web-based learning formats - the traditional linear PowerPoint format (with voice-over) and a new interactive format developed with central nursing education. The investigators will cluster randomize nurses by floor to receive either the traditional education or the new interactive education, and evaluate the impact on administration of VTE prophylaxis doses administered by nurses before and after education. All nurses on a floor will receive the same educational format. If one method of education results in statistically significant improvement in VTE prophylaxis administration, the investigators will cross over to deliver the superior education format to all nurses who originally were given the less effective method.
The primary objective is to demonstrate the non-inferiority of edoxaban (preceded by a short course of LMWH) compared with dalteparin for the prevention of the combined outcome of recurrent venous thromboembolism (VTE) or major bleeding in subjects with VTE associated with cancer during a 12-month study period. If non-inferiority is established, LMWH/edoxaban will be compared with dalteparin for superiority.
This is a multicenter, randomized, double-blind, event-driven, superiority study for efficacy. Patients with confirmed symptomatic DVT (Deep Vein Thrombosis) or PE (Pulmonary embolism) who completed 6 or 12 months of treatment of anticoagulation are eligible for this trial
