tom. you are called dr. tom by the staff there because i know that you're back at the hospital after a seven-month furlough due to this pandemic and the medical teams were cheering for you when you came back. i know you have a particular concern for the medical staff, particularly the nurses there. again, don't want to compromise confidentiality you have with your teams but we know the fatigue, emotional well being of frontline workers is real, it's something a lot of people are concerned about. what do you see at their most urgent need and what conversations do you have to help? >> they're always in a state of urgent care in the emergency department in the icus. but the pandemic has increased that by ten-fold. they have more patients to deal with, patients need more care. it stresses them very much and you don't have facial recognition anymore because we're wearing our masks.
