I have a related question... The two big EHR systems (Epic and Cerner) are infamously complicated, user-unfriendly monoliths. And they're not interoperable, so once you pick one, it's very hard and expensive to switch your hospital to the other. My question is, could EHR be "refactored" into smaller pieces? So your billing system is provided by Vendor X, and your imaging system is provided by Vendor Y, and they all talk to each other over an open protocol? That would make it easier for hospitals to switch away from individual systems / vendors that they hate.
