Prevention of venous thromboembolism: a key patient safety priority

Abstract

It is more than 50 years since the first publication of a study showing that symptomatic and fatal venous thromboembolism could be reduced with the use of thromboprophylaxis. Furthermore, it is 23 years since the first evidence-based guidelines recommended routine use of thromboprophylaxis for most hospitalized patients. However, despite the overwhelming evidence that thromboprophylaxis safely and inexpensively reduces thromboembolic complications associated with acute illness and surgery, there continue to be large gaps in the provision of this key patient safety intervention and even larger gaps in the provision of optimal thromboprophylaxis. The implementation of quality improvement strategies, both at the national level and in local hospitals, are able to increase awareness of thromboembolic risks, to increase adherence to thromboprophylaxis guidelines, and to decrease both clinically important thromboembolic events and hospital costs. Therefore, the objective is for every hospitalized patient to receive appropriate thromboprophylaxis based on their thromboembolic and bleeding risks.
