Over the past 25 years, Dr. Geerts has developed and participated in clinical research in all aspects of thromboembolism, including epidemiology, diagnosis, treatment and prevention. His primary interest has been in the prevention of venous thromboembolism (VTE) in high-risk patients, especially following trauma. He has performed the most comprehensive, prospective study of the risks of venous thromboembolism in trauma patients and found that they are the highest-risk group for thromboembolism in hospitals.
Subsequently, Dr. Geerts and his group conducted the first large randomized trial of thromboprophylaxis in major trauma patients, by comparing subcutaneous low-dose heparin with low molecular weight heparin in a double-blinded manner. This study demonstrated that the early use of low molecular weight heparin is more efficacious than low-dose heparin in trauma patients without increasing bleeding.
His current research interests extend to the implementation of knowledge about thromboembolism into clinical practice.
