>I've never seen Zivver used in German Healthcare.
How would you even be sure of this just from what you can see from the outside? That doesn't mean your health insurance company isn't using Zivver internally same how they use Office 365 or SAP. It's not like they tell you all the SW they use.
Internally, you have the Hospital Information System where you can look up all the informations you need.
I can just say I know the inside of one of Germany's biggest Hospitals, since I'm a Doctor. And requesting Patient Data or giving it out to other Parties is unfortunately a Task that Doctors still have to do on their own
And for communication with the outside world it's down to Fax, Phone or Letter.
Theoretically they could already send this via S/MIME encrypted Mail (KIM) to the family doctor, but most Hospitals haven't rolled out this service yet.
They just started installing Card Readers for the Doctor Identity Cards, so they can issue electronic prescriptions
For communication with Patients some Hospitals have Web Portals/Apps for getting/sending information.
That's pretty interesting. We have electronic prescriptions too (though it goes straight to the pharmacy however - we don't see it).
As far as I know, I don't think the hospital portal has ever been used for communication like that. An email seems more "obvious" perhaps to the docs, and that's what they use most of the time.
