Pulmonary embolism response teams.

OPINION STATEMENT: Pulmonary embolism (PE) is a complex and multidimensional pathophysiology, the diagnosis and management of which spans multiple disciplines. The high morbidity and associated mortality of "massive" and "submassive" acute PE may require prompt, definitive management; however, current consensus guidelines in this domain are not supported by high-level evidence. Randomized clinical trials comparing available pharmacologic and invasive treatment modalities-including anticoagulation, thrombolysis, and embolectomy-have not been conducted and continue to be challenging to conceptualize, design, and execute. Consequently, time-sensitive therapeutic determinations are largely not standardized, and rendered on a case-by-case basis in part depending on institutional practices and expertises. Chronic sequelae of PE, such as chronic thromboembolic pulmonary hypertension and right heart failure, are increasingly identified as conditions necessitating longitudinal specialty care. These and other challenges have created a niche for a multidisciplinary team which can respond rapidly to unstable patient scenarios, appropriately deploy resources, and offer highly specialized acute and chronic management of PE. The Massachusetts General Hospital Pulmonary Embolism Response Team (PERT), modeled after existing rapid response and collaborative care teams, is a novel approach that combines this clinical service with the development of an educational and research framework to advance the care of patients with PE.
