Physicians are trained to deal with medical emergencies, but COVID-19 thrust hospitals in Phoenix — and around the world — into crisis mode for nearly a year. Phoenix was a COVID hotspot, as were other cities like New York. There have been 30 million cases and more than 540,000 deaths in the US, nearly 17,000 of whom were Arizonans. This was a tremendous test of crisis leadership as medical teams worked to understand the disease, identify treatment protocols and share valuable information. Marilyn Glassberg, MD, shares insights from her experience leading frontline teams and how a tweet led to a new predictive model for COVID lungs. * Episode Guest: Marilyn Glassberg, MD * Hosted by: Jonathan Lifshitz, PhD and Katie Brite, MD
