Curbside Consults Podcast

Published June 13, 2019

Winter is upon us and asthma exacerbations are on the rise. But how well can clinicians and patients predict and prevent these asthma exacerbations before they start? NEJM Editor-in-Chief and Pulmonologist Dr. Jeff Drazen discusses the challenge clinicians and patients face in the setting of worsening asthma symptoms, also known as the “Yellow Zone”, the research behind treatments for exacerbation prevention and its clinical applications.

The Curbside Consults series complements the foundational information in NEJM R360 Rotation Prep by taking a deep dive into key clinical topics with expert clinicians and educators. These podcasts explore and critique the evidence behind clinical practice and break down statistical concepts for the busy clinical trainee.
