Outpatient management of pulmonary emboli: when to ambulate

Pulmonary embolism is a potentially fatal consequence of venous thromboembolism and constitutes a significant proportion of the acute medical take. Standard management has previously required admission of all patients presenting with acute pulmonary embolism for initiation of anticoagulation and initial investigations. However, clinical trial data have demonstrated the feasibility and safety of managing a subset of patients with low-risk pulmonary embolism in the outpatient setting and this has since been reflected in national guidelines. This article provides a practical overview for general physicians with regards to identifying patients with low-risk pulmonary embolism, and when and how to manage these patients on an outpatient basis.
