About
Biography
Leora Horwitz, MD is a general internist who studied social science as an undergraduate and is now a clinician researcher focused on quality and safety in healthcare. In particular, she focuses on systems and practices intended to bridge gaps or discontinuities in care. She has studied shift-to-shift transfers among physicians and among nurses, transfers from the emergency department to inpatient units, and the transition from the hospital to home. She is currently adjunct faculty at Yale; her primary work is at NYU Langone Health, where she directs the Center for Healthcare Innovation and Delivery Science and the division of healthcare delivery science in the Department of Population Health. Her current work is focused primarily on developing a learning health system through innovations in clinical delivery and in data capture and analysis.
