Figure 4. Outcomes Chain for Hospital-Acquired Venous Thromboembolism Preventing Hospital-Acquired Venous Thromboembolism Whether a patient develops a preventable hospital-acquired deep vein thrombosis (DVT) or pulmonary embolism (PE) depends heavily on recent, appropriate venous thromboembolism (VTE) prophylaxis. While one key metric to track is the intermediate outcome "appropriate VTE prophylaxis," the more proximal steps in the care delivery pathway are where care redesign will likely occur (e.g., the VTE protocol). The other key metric to track is the prevalence of hospital-acquired DVT or PE.[D] Select for Text DescriptionReturn to Document Current as of August 2008 Internet Citation: Figure 4.
