Geez, people, take off your tinfoil hats.
As someone who has been bouncing between 15 different doctors over the past couple of months, having countless tests done for various issues, I will WELCOME an integrated, platform-agnostic database/piece of technology that shows every doctor, nurse, and yes, insurance person who needs said info, all the pertinent information related to my medical history. I am sick (no pun intended) of having to set up accounts and download apps for every hospital, imaging service, doctor's office, and clinic. They're all trying to make it easier by creating their own app, but keeping track of everything that's been done is a logistical nightmare, not to mention inefficient when it comes to relaying data between medical entities. In short, there's no centralized database they can all share. It's like passing an amendment to the Constitution for these institutions and people to have quick access to all my medical history... If tech companies can come up with a way to make all of the above easier, I'm on board 100%. And yes, it will be secure. The paranoia over stolen personal data will likely ensure privacy and security remain a top priority.
Okay fine, keep your tinfoil hats on.
