In Denmark, we have a central registry for health information where all information is shared between medical practitioners and hospitals on a need to know basis.

We also have sundhed.dk (would translate to health.com) which all citizens can log into.

Here you can:

  - See upcoming appointments with hospitals or doctors
  - Sign up for organ donation or do not resuscitate orders
  - Information about hospital visits 50 years back (records have been digitized)
  - All your dentist visits, what kind of treatment you got, how much did you pay.
  - X-rays are digitalized and you can download them if you want to.
  - Lab results with explanations and tracking over time.
  - All the medicine you have bought and prescriptions you might have.
  - Your treatment plans which can be coordinated between medical practitioners and hospitals

You also have access to all information about any children under 15. And you can give access to information of your choosing to next of kin.
