Ask HN: Managing and sharing personal health records?

So I've been in Germany for a while now and the other day had to visit a doctor for the first time in a few years. I was a bit surprised when one of the nurses approached me to fill out a paper form with some basic information about myself: name, phone number, medications, past history, etc. Why was I surprised? Because we're in 2015 and the way this should work is that someone should be able to scan my medical card (which has an electronic chip in it BTW) and get access to whatever information I've chosen to share. I can't even imagine how hard this is for the elderly to manage...

What are your thoughts on this? Do you personally use anything to manage your own health records(e.g. Microsoft's Health Vault)? I'm thinking something should exist that is like Snapchat\Dropbox for medical records where I can choose what to give access to and to whom for whatever period is necessary. Cheers!
