Ronald Epstein, M.D. discusses his powerful and accessible book, Attending: Medicine, Mindfulness, and Humanity. As a third-year Harvard Medical student doing a clinical rotation in surgery, Ronald Epstein watched an experienced surgeon fail to notice his patient s kidney turning an ominous shade of blue. In that same rotation, Epstein was awestruck by another surgeon s ability to slow down and shift between autopilot and intentionality. The difference between these two doctors left a lasting impression on Epstein and set the stage for his life s work to identify the qualities and habits that distinguish masterful doctors from those who are merely competent. The secret, he learned, was mindfulness.
