Welcome. I second some of the stuff earlier - especially regarding sponge bath and bedsores. If you got some, you need to at least talk to the hospital about it. Unless you're 90 and demented, it should be fairly easy to avoid them. Then again... if you're bed bound at home and developing them, it's a different story.
Would a GPS have helped? I doubt the first responders or ambulance has a GPS that reads out the grid coordinates. They'd be lucky to have a street-level GPS.
Probably a good call on Kaiser, if only for insurance. yeah, they might or might not have transferred you, but if they didn't you might have more headaches from insurance.
It does kind of sound like you were a bit bossy, but not being there, it's not really my place to critisize. BTW, they would have cut your shorts anyway

Time to sit down with your family at an ARC First aid course?
