Official title
Intermediate or Prophylactic-Dose Anticoagulation for Venous or Arterial Thromboembolism in Severe COVID-19: A Cluster Based Randomized Selection Trial (IMPROVE-COVID)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
