A review of venous thromboembolism prophylaxis for hospitalized medical patients

In the last decade, greater focus has been directed toward venous thromboembolism (VTE) prophylaxis in hospitalized, non-surgical patients. Both deep venous thrombosis and pulmonary embolism are potentially preventable causes of patient morbidity and mortality related to hospitalization. Despite the availability of high-quality, evidence-based guidelines for VTE prevention, there is compelling evidence that many hospitalized patients do not receive appropriate VTE prevention measures. Hospitalists play an important role in the implementation of appropriate VTE prophylaxis measures for this patient population; thus, knowledge of updated recommendations is vital to their practice, as well as patient safety. We provide a comprehensive evidence-based clinical review of VTE prophylaxis for nonsurgical hospitalized patients, including risk factors and risk assessment, indications for prophylaxis, recommended therapeutic options, and updates from recently released practice guidelines by the American College of Physicians and the American College of Chest Physicians, published in 2011 and 2012, respectively.
