The biggest exemption was for us working on the systems.
The idea that whispering in the waiting room was an important attack vector while whitelisting us IT people is hilarious. (For lack of a better adjective.)
For a middle ground example:
My SO did clinical trials at the local research hospital. She went to ANOTHER hospital for some surgery, because she knows her coworkers look up people's records, and she didn't want them knowing about her troubles.
Like the systems I created, of course there were access logs. But like our systems, no one ever reviewed or audited them.
Hopefully things have gotten better.
