Ultrasound & Echocardiography

On a weekly basis, thousands of patients presenting to EDs receive unnecessary computed tomography (CT) scans known to have adverse health outcomes including death when, at times, an alternative diagnostic technique such as ultrasound would suffice. Beyond the health implications, CTs are placing a significant burden on the health care system and accounting for 23% of Medicare expenditures. Ground-breaking research conducted in the Yale ED is aimed at identifying unnecessary irradiation of patients to improve practice and health outcomes for patients.


Simulation research in Emergency Medicine at Yale focuses on both resident and medical student education as well as patient safety. Our specific research interests are in procedural simulation - the development of assessment tools, skills transfer to the clinical setting and skills decay. Simulation research also focuses on team interactions and leadership skills during acute trauma resuscitation.

Simulation training at Yale’s Department of Emergency Medicine includes training with partial task trainers, computer based micro-simulators and high fidelity mannequin simulators.

Unexplained Chest Pain and Gender

Research in the Yale ED Chest Pain Center aims to better understand the etiology of chest pain and progression of heart disease in men and women; investigate the use of non invasive techniques such as flow mediated dilatation and PET scans to improve our understanding of unexplained chest pain and its link with microvascular dysfunction; and, to study the gender related predictors of future adverse coronary events, poor health status and repeat health service utilization in patients with unexplained chest pain.
