Fifteen years ago, Dr. Brian Goldman gave us a front-line account of life in the emergency room with his book The Night Shift. Now, the ER physician and host of CBC's White Coat, Black Art and The Dose is revisiting that setting with his new book The Casino Shift. He joins Piya Chattopadhyay to discuss what’s changed for the better and worse at ERs across our country in the last 15 years, and what treatments for our ailing system may look like.
