1 Increased Risk of Venous Thromboembolism and Higher Hypercoagulable State in Patients Recovered in Intensive Care Unit and in Medical Ward for Coronavirus Disease 2019 (COVID-19)

The aim of this study is to verify if patients admitted to hospital in a medical division and in the intensive care unit for a COVID-19 infection are at higher risk of developing a VTE complication and if they actually present an increased hypercoagulable state.

NCT04359212 COVID-19 Disease Thromboembolism, Venous Drug: thromboprophylaxis with low-molecular-weight heparin or fondaparinux

MeSH:Thromboembolism Venous Thromboembolism

HPO:Thromboembolism

2 Intermediate or Prophylactic-Dose Anticoagulation for Venous or Arterial Thromboembolism in Severe COVID-19: A Cluster Based Randomized Selection Trial (IMPROVE-COVID)

This study is being conducted to assess the effectiveness of intermediate versus prophylactic doses of anticoagulation (blood thinners) in patients critically ill with COVID-19 in the intensive care units (ICUs) throughout the hospital. Anticoagulation is part of the patient's usual standard of care but determining the dose of anticoagulation is based on physician preference. The investigators are conducting this study (a randomized trial with adaptive design employing cluster randomization) with the support of all of the ICUs to collect data in order to determine what should be the standard of care in terms of anticoagulation in these critically ill patients. The patients care will not be altered other than the choice of anticoagulation (both approved and used throughout the hospital as standard of care) based on the ICU bed they are assigned. Patient data will be collected until discharge.

3 Effectiveness of Weight-adjusted Prophylactic Low Molecular Weight Heparin Doses Compared With Lower Fixed Prophylactic Doses to Prevent Venous Thromboembolism in COVID-2019. The Multicenter Randomized Controlled Open-label Trial COVI-DOSE

Worldwide observational studies indicate a significant prothrombogenic effect associated with SARS-CoV-2 infection with a high incidence of venous thromboembolism (VTE), notably life-threatening pulmonary embolism. According to recommendations for acute medical illnesses, all COVID-19 hospitalized patients should be given VTE prophylaxis such as a low molecular weight heparin (LMWH). A standard prophylactic dose (eg. Enoxaparin 4000IU once daily) could be insufficient in obese patients and VTE has been reported in patients treated with a standard prophylactic dose. In COVID-19 patients, guidelines from several international societies confirm the existence of an hypercoagulability and the importance of thromboprophylaxis but the "optimal dose is unknown" and comparative studies are needed. In view of these elements, carrying out a trial comparing various therapeutic strategies for the prevention of VTE in hospitalized patients with COVID-19 constitutes a health emergency. Thus, we hypothesize that an increased prophylactic dose of weight-adjusted LMWH would be greater than a lower prophylactic dose of LMWH to reduce the risk of life-threatening VTE in hospitalized patients. The benefit-risk balance of this increase dose will be carefully evaluated because of bleeding complications favored by possible renal / hepatic dysfunctions, drug interactions or invasive procedures in COVID-19 patients. This multicenter randomized (1:1) open-label controlled trial will randomize hospitalized adults with COVID-19 infection to weight-adjusted prophylactic dose vs. lower prophylactic dose of LMWH.

4 Risk of Venous Thromboembolism in Critically Ill Patients With Severe COVID-19

Severe COVID-19 patients at a high risk of venous thromboembolism. We studied patients in 2 intensive care units of university hospitals in Barcelona and Badalona, Spain. We performed a cut-off screening of deep venous thrombosis (DVT) with bilateral duplex ultrasound to 230 patients.

5 Impact of Implementation of an Intensified Thromboprofylaxis Protocol in in Critically Ill ICU Patients With COVID-19: a Longitudinal Controlled Before-after Study

The aim of this study is to investigate and compare the mortality, the incidence of DVT and the incidence of kidney and liver failure in patients admitted to the ICU before and after the implementation of an intensified thromboprofylaxis protocol on 31st of March 2020. Patients in the before group are admitted at the ICU from 13/3/2020-30/3/2020 and patients in the after group are admitted to the ICU from 31/3 until 20/4/2020.
