Same way they worked before computers? Fax machines still exist.
Well now the patient data is not really locked away in a specific office.
How about physical mailing?

Sure, send the patient data over an unencrypted phone line, probably using a never-updated smart scanner to an internet-connected IoT-printer. Sounds like a plan!
You could make the same argument about the mail system.
And I would! While mail is not as easy to monitor at scale or distance, the files of single patients are even less protected; catching a letter is rather trivial if one really wants to.
In what part of the world? I haven't seen one in Finland since maybe the early 2000's.
