That's basically medical information system vendors.
The fact that the US hasn't pushed open source EMRs through CMS is insane. It's literally the perfect problem for an open solution.
I know OpenMRS exists but is mainly used within developing nations.
The US has Vista, made by VA, and it is a beast and no one really wants to use it.
EMR software seems like something that shouldn't be that hard. It's fundamentally a CRUD. Sure, there's a lot of legacy to interface with, but medical software seems like a deeply dysfunctional and probably corrupt industry.
Estonia's from-scratch system was reportedly about 10 million euros.
It's not insane, it's because the US is an oligarchy. And it's about to go even more oligarchy on steroids in the next year.
Is Sweden an oligarchy, too? Or France? Etc etc
