This has proven to be true in my when dealing with my own recent health problems. Faxing is terribly inefficient and prone to human error.
Given an estimated 32 million new people with insurance due to the ACA and the baby boomers getting older and in need of more healthcare, the last thing we need medical staff dealing with is unnecessary paperwork. (And all the delays in treatment that come with that.)
This article is quick to hand out blame, but these companies do provide legitimate services hosting records and developing programs to write them. That said, these companies do make stupid amounts of money for their systems. The ADA should have standardized electronic records years ago, but of course they've never been embracing of technology so we're stuck here. I imagine we'll get a law forcing companies to freely share records or something, getting the government to store all medical records would probably cause more problems than it would fix.
