Having been through all I've been through with DP, I so agree with the medical history information - I can rattle it off, thankfully, and have two versions, the 'nurse doing intake' short version and the 'doctor that really needs to know' long form. If you can't rattle it off, or fear you may be unconscious, then get it down and put it somewhere it can be found. Most phones can have an ICE program added to them, which can contain medical information, contacts, etc. for emergencies. DP's entry on her phone is MASSIVE. Mine is short. Both of us have it, though.
Advocating for yourself/someone else - I had to get the medical director of the hospital involved with DP's care once. I'm actually writing a 'how to' kind of book for families of long term hospital patients because of the things I had to learn the hard way - there just aren't any resources out there for families. Dr. Google can actually be useful IF you are using it the right way - as a way to learn what the terms the doctor uses mean, to learn about the side effects of medications (and why they may be given), and as a 'are we looking for this condition with this test?' check. You can't (or shouldn't) diagnose yourself or someone else with a Google search, but you certainly can use it to get some background and understand what's going on better.
