Designing the virtual queue

We've all waited in an online queue to get a table at a busy restaurant or buy concert tickets for our favourite big artist. But what about waiting to see a doctor at the emergency room? A hospital in Sault Ste. Marie, ON., is offering their patients just that --and staff say it's cut their patient wait times in half. We speak with Dr. Stephen Smith, an ER physician and the vice president of medical affairs at the Sault Area Hospital, who came up with the idea after a family vacation at Disneyworld.
