Hospital-Acquired Venous Thromboembolism (VTE) Incidence Calculator

Society of Hospital Medicine (SHM)
Philadelphia, Pennsylvania, USA

 

Use this calculator tool to estimate the number of hospital-acquired venous thromboembolism (VTE) at your hospital, and the proportion that are potentially preventable.

 

Background

According to the Society of Hospital Medicine, venous thromboembolic disease, ranging from asymptomatic deep vein thrombosis (DVT) to massive pulmonary embolism (PE), is a significant cause of morbidity and mortality in hospitalized patients. Many clinical trials have provided evidence that primary thromboprophylaxis reduces the incidence of DVT and PE.[1] Unfortunately, numerous studies have also shown that the majority of hospitalized patients with risk factors for DVT do not receive appropriate prophylaxis.[2-4]
