Led by Robert Hirten, MD and Zahi Fayad, PhD, the study draws upon the collaborative efforts of the Mount Sinai COVID Informatics Center (MSCIC) and is open to all employees in the health system. It uses a unique phone App to administer questions and collect data from an Apple Watch, worn by participants, in order to better understand the impact of COVID-19. Utilizing this unique digital platform, it has two goals. The first goal is to study and understand the impact that COVID-19 is having on the psychological well-being of health care workers and understand how this stress can be improved. The second goal is to identify COVID-19 infections in our employees prior to the development of symptoms.
