Venous thromboembolism prophylaxis

Venous thromboembolism is a common and frequent complication of hospitalized patients.

Venous thromboembolism and pulmonary embolism contribute significantly to in hospital morbidity and mortality. The risk of venous thromboembolism is aggravated by dispositional and/or expositional risk factors. In patients at intermediate or high risk of venous thromboembolism, additional pharmacological thromboembolism prophylaxis becomes mandatory.
