doing financial audits, do pharmacy audits, checking for overdue records, checking to see if you are overdue for an appointment, checking the status of an insurance claim (twenty times a day), counting the number of diabetics, counting the number of people who need tetanus shots.
You shouldn't have to access my personal medical records for that, I'm not talking about generic hospital administration stuff. In fact over here you're not even allowed to access medical records for any of those reasons, the best you get is anonymized aggregated data. Hospitals do keep a lot of additional data in order to keep their books in order, but even so that information is still classed extremely sensitive, and they're not about to open up that data to other parties like insurance companies (though insurers have pushed for wider access to that data as well).
In the EU, the EU or its collections of institutions is often referred to as "Europe".
And yes, they are written in legal language, laws usually are, and yes they are treaties because that is what laws between countries are.
Treaties are written in legalese, and they have to, as they deal with details. Constitutions on the other hand deal with base principles, ideals, and ground rules, and they can and usually are written in short and extremely accessible language. In case of Europe (I'll just keep calling it that), the treaties would need to follow from the constitution.
