Mine contains exactly zero info that isn't already stored elsewhere with the same levels of security.
On the subject of security, how secure do you think the data your local GP or specialist has on you is? In many places, it's not great - does your doc lock their PC if they leave the room? In addition to that, it's often reasonably easy to get physical access to a server in a GP's practice and then you just clone the whole disk and walk. And those doctors out there still using paper files? There's no real security there.
