Worsening Asthma Symptoms and Preventing Asthma Exacerbations with Dr. Jeff Drazen

Published

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.
