First and foremost what do your protocols say? Are they a hard and fast "You will board and collar these patients" with no consideration to actual patient condition, or does it give you leeway to decide different levels of SMR based on patient assessment (I.e. full board and collar, collar and position of comfort on gurney, neither, etc) What follow on assessment did the medics do? What was the distal CMS in all four extremities? Was the patient moving around at all, attempting to sit/stand up? Any other injuries besides the broken teeth, where was the bleeding from? How well was the patient tolerating the collar to begin with? (We once had an auto vs. scooter patient we put in a collar, and he immediately began gagging so we took it off)
FWIW a trauma patient here, with a fall greater than 15 feet, head injury, and ALOC would get a full board and collar and transport to the local Level I or II trauma center (depending on which one is closer), but LA Co SMR policy is still a bit more restrictive than a lot of other places lol
