A revolution is occurring in the way medical care is being delivered in the United States. It is happening almost overnight. People have stopped going to hospital emergency rooms. They have stopped going to doctors’ offices. Most of the nation is self-isolating. Doctors and patients are no exception. They are communicating by means of phone, email, Skype, Zoom and other devices. Last December, Zoom was the host of 10 million video conferences a day. Last week, the company was hosting 200 million a day. Many of those were patient/doctor communications.
