Agree w/ the prior posters. Former EMS here too

Name, DOB, your version of SSN. point of contact (do you have the ICE concept up there?). Everything else is gravy.

I'd put pertinent medication/medical history in lieu of blood type or address. NKDA is fine, don't need NKA (no one really cares if you have allergies to strawberries or bermuda grass). But something like you're on coumadin or humira? You're G6PD negative? Absolutely good idea.

Skip any surgeries - most of us can read the operations by looking at your scars, and in reality it's not going to help if we scrape you off the road.
