Just coming across this topic. I love Evernote, but it can't cover everything. In summary, you have two needs: One is getting important emergency information to a provider, and the other is keeping track of the details of the health information you've acquired. I'd second the comments others have regarding using USB sticks, as those can be potential sources of viral (the computer type, not human type!) infections. Plus, you always need to have the flashdrive on your body (or others remember to carry their copy with them). For the first, I'd suggest something that's on your body. The known standard is the MedicAlert. My mother-in-law wears a MedicAlert bracelet. It's $45 to join and $45 per year for renewal. I know (from their website) that they store emergency contacts, medications, allergies, implantable devices, physician and insurance information. Personally to me, the logo screams out "I have a problem!" to any one looking at the id, rather than "look at me for information". I don't know what the information looks like to an emergency responder. I believe it's a phone call to get the emergency information. I use a RoadID which serves the same function, but is marketed towards people who are active in sports (like cyclists) who want to carry identification, but there's no reason why anyone can't use this. My main function is for emergency contact as I row and wanted a water tolerant ID, for those times I row alone. Here's the link: http://www.roadid.com/Common/Products.aspx If you pay and use for the Interactive version, which is for example has a slim bracelet (like a "cause" bracelet") which is $15.99, and includes one year of interactive service, with renewals of 9.99 per year after that. The interactive bracelet can have some very basic info on it (like emergency phone number) but also includes a phone number and web link to your profile, using the serial and pin number which are on the reverse (covered by your wrist). The interactive information I think includes everything in Medicalert, such meds, phone numbers and names for multiple docs and family members, medical conditions, advanced directives, and essentially all information can be supplemented with notes. Also, your profile information can be printed to a PDF, then saved to Evernote, and you could reference that PDF file in a Shared Notebook by putting the URL in the Miscellaneous Section of RoadID. So, you could use the RoadID as your primary data entry point, then periodically update your PDF in Evernote. RoadID is missing a lab values section, and you might want to use your Evernote Notebook for that, and maybe use Evernote to keep old details of physician visits. Evernote might also be a good place to include your notarized/witnessed copy of your Living Will and Advanced Directives. In the cheapest version of this, you could get the RoadID non-interactive version, or any other engraved dogtag or ID, and include the URL to your Evernote Notebook, but then if the URL changes because you've rearranged your Evernote, you're out of luck. Also, the large hospital system I work with locks out many sites for security purposes. I *think* but am not sure that Evernote is one of those locked out sites; fortunately, as i use Evernote extensively for reference material, I can access it with my iPad through the guest wifi.
