Filter by:The goal of this observational study is to analyse the association between anti-factor Xa activity (antiXa) and the occurence of venous thromboembolism (VTE; either deep vein thrombosis and/or pulmonary embolism) in critically ill patients who are admitted to an intensive care unit. The main questions it aims to answer are: - What is the association between antiXa and VTE? - What is the association between antiXa and symptomatic, respectively incidental, VTE? - How is pharmacological anticoagulation with enoxaparin related to measured antiXa? - What is the association between antiXa and bleeding complications. - What is the incidence of venous thromboembolism in patients treated at an intensive care unit? - How is the occurence of VTE related to patient-centred outcomes such as mortality, quality of life, length of stay and days outside of the intensive care unit/hospital.
Venous thromboembolism (VTE) is the third leading cause of cardiovascular disease deaths globally, and its incidence is increasing over the years. Hospital-acquired VTE accounts for approximately 75% of all deaths attributed to VTE. However, only half of patients with indications for VTE prophylaxis take preventive measures, and high rates of inappropriate VTE prophylaxis prescribing contribute to the gap between VTE prophylaxis and guidelines. To further minimize the gap between clinical practice and guidelines, a range of strategies have been employed across various fields of VTE prophylaxis. One of the most effective measures is the utilization of a Clinical Decision Support System (CDSS). Smart technology-based CDSS facilitates automated evaluation of VTE risk and detection, addressing issues at both the beginning and end of the in-hospital VTE prevention process. but there is still a lack of research on how to effectively implement evidence-based VTE prophylaxis in the middle of the process. In our hospital, routine use of DeVTEcare system (a CDSS for VTE risk assessment and integrated care) for in-hospital management of VTE has been launched since 2021. This study aims to investigate the effect of integrating bundled guideline-based VTE prevention strategies into the DeVTEcare system on in-hospital VTE prophylaxis.
Smart technologies, such as wearable devices, mobile technologies, and artificial intelligence, are being investigated for use in health management. These technologies have the potential to be applied in disease pre-warning, decision-making support, health education, and healthcare maintenance. They are expected to address the challenges in managing thrombosis, improve access to high-quality medical resources in various regions, and enhance the development of a network for thrombosis rescue and treatment prevention. The objective of this study is to observe the long-term effect of mobile venous thromboembolism application (mVTEA) based patient-centered management of venous thromboembolism (VTE) on thromboprophylaxis, and establish a foundation of evidence for managing patients with high-risk VTE.

Multicenter longitudinal observational ambispective (retrospective cases from 2014 and prospective from 2018 onwards) cohort study. The registry recruits a series of consecutive patients admitted for moderate-high risk or high-risk pulmonary embolism (according to 2019 European Society of Cardiology guidelines) treated invasively. This study aims to describe the acute management of the safety and effectiveness of different percutaneous interventions for acute pulmonary embolism.
The goal of this prospective observational study is to explore the influencing factors of the efficacy and safety of anticoagulant therapy for pulmonary thromboembolism in special populations with older age, renal insufficiency or co-existing malignancy, and establish a predictive model to guide clinical practice. The main questions it aims to answer are: - To analyze the influencing factors of the efficacy and safety of anticoagulant therapy for specific populations with pulmonary thromboembolism (PTE) in the real world (such as the elderly, those with impaired kidney function, and individuals with malignant tumors). - Whether we can use machine-learning models to predict bleeding events and VTE recurrence in special populations following anticoagulant therapy in the real world? Participants will receive diagnostic and therapeutic measures for pulmonary thromboembolism in accordance with clinical guidelines, including anticoagulant therapy. Some patients need to have peripheral blood samples collected at the time of enrollment and 3 months after anticoagulant therapy.
The goal of this quasi-experimental study is to examine the effects of a venous thromboembolism prevention program, or "5E" program, on the rates of venous thromboembolism in patients with spinal cord disorders. The main questions it aims to answer are: - Will participants receiving the 5E program have lower rates of venous thromboembolism compared to those receiving the usual care? - Will participants receiving the 5E program have lower scores of venous thromboembolism signs and symptoms compared to those receiving the usual care? - Will the average thigh and calf circumferences of participants before and after receiving the 5E program be different? Participants in the intervention group will receive the 5E program, including - Education: health education regarding venous thromboembolism prevention - Elevation: leg elevation of 10-20 degrees - Exercise: ankle exercises - Enough fluid: adequate fluid uptake - Early application of intermittent pneumatic compression (IPC): IPC use within 48 hours after admission
Aim of our study is to find frequency and identify risk factors for venous thromboembolism development in patients who underwent surgery for colorectal cancer. There were 137 patients enrolled in our retrospective observational cohort study. Included patients were operated for incisional hernia in Saveljev University Surgery Clinic from January 2016 to December 2017. Compression duplex ultrasound of lower legs veins was performed in 2-14 days after surgery for all participants. The primary endpoint was the occurrence of the venous thromboembolism event, including pulmonary embolism.
This study is researching 2 different experimental drugs called REGN9933 and REGN7508 (called "study drugs"). The study is focused on adults undergoing a placement of a catheter in your vein, also called a 'PICC line'. The aim of the study is to see how effective the study drug is at preventing venous thromboembolism (VTE) and other related disease after catheter placement. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in your blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
Cancer patients are burdened by an increased risk of venous thromboembolism (VTE), which has a significant impact on morbidity and mortality. Existing Risk Prediction Models (RPMs), including the widely accepted Khorana Risk Score (KRS), have some limitations when used in certain tumor site populations, such as gynecological cancers. Notably, gynecological patients exhibit a variable risk of VTE based on their specific tumor sites, with ovarian cancer representing the highest risk. Moreover, currently available RPMs lack validation in a broad gynecological population and may fail to effectively stratify VTE risk. GynCAT is a prospective cohort study that will be conducted on female patients with gynecologic malignancies scheduled for systemic antineoplastic treatment. During the screening phase, symptomatic VTE will be excluded, and KRS will be assessed. Pharmacological thromboprophylaxis will be considered and prescribed at clinical judgement, for patients with a KRS score of 3 or higher. Clinical, hematological, biochemical, coagulation, and genetic variables will be collected. Follow-up will last for the entire duration of the antineoplastic treatment line, and VTE events, bleeding events, and mortality will be recorded. The primary objective is the development and validation of an RPM for VTE in gynecologic cancer patients undergoing systemic antineoplastic treatment. Secondary objectives are evaluation of the predictive value of the identified model, comparing it with existing general oncology RPMs; assessment of its performance in predicting mortality; evaluation of VTE incidence in patients with KRSā„3 receiving thromboprophylaxis; identification of risk factors for bleeding in this patient population. The sample size calculation is based on an estimated VTE incidence of 5% over a mean follow-up of 12 months. Hence, a sample size of at least 1,200 patients in the derivation cohort is considered sufficient for the determination of a risk prediction model incorporating up to six predictor variables. A split-sample method will be used, with two-thirds of the study participants randomly assigned to the model derivation cohort (n=1,200) and one-third (n=600) to an independent validation cohort. The total number of patients recruited in the study will thus be of 1,800. A competing risk survival analysis with Fine & Gray model will be used to study the association between prognostic variables and VTE occurrence, considering death as a competitive risk. The RPM will be identified through a bootstrap approach to reduce the risk of overfitting. Discrimination power of the RPM will be assessed using time-dependent Receiving Operating Characteristic curve, and model calibration will be evaluated graphically and with the calculation of relative calibration slopes. In conclusion, this prospective cohort study aims to overcome the limitations of current RPMs in gynecologic cancer patients, improving the accuracy of VTE risk stratification in this population.
