Healthcare has long resisted change more tenaciously than other industries. When I came to ophthalmology about 15 years ago with the idea patients should be able to schedule appointments online with their doctor, the vast majority of doctors had no interest. They understood consumers wanted this, but they generally feared the disruption to their schedules. Yet airlines had been allowing travelers to book flights online for 7 years and some 40% of airline travel was already being booked online.
