Health care professionals can get treated like cogs in a wheel, too. I recently switched the dr's office I go to, because the doctor left. I followed the doctor to a different practice. My doctor was a little surprised that I did that - I guess most people don't? My answer was simply that "you listen to me". When my doc explained the switch between offices, it was in part because of the way they were treated by the old office.

Bringing this back around to the original question, if whatever leads you to a hospital isn't trauma, having your primary doctor's name on you probably wouldn't be a bad idea? Baring some sort of large scale emergency, they would have access to your medical records, and might provide some other insight as well as potentially being an advocate for you.
