A big problem with American EMS is the instructors. Many times we are looking at the blind leading the blinder.
If there is a question as to whether you should immobilize, than odds are you aren't at the level of experience, both classroom and clinical, that you need to be to be a truly competent provider. More often than not, especially in this case presented in this thread, the need for immobilization should be obvious.
Did you ask those medics why they did something the way they did it? Yes people often do things out of laziness but other times they do it because it was warranted. Our protocols have a line in them that says "these protocols are not to be used in place of good clinical judgement."
Protocols are a guideline to what I CAN do, not what I have to do. I can't exceed their limitations without further approval but that doesn't mean I always need to work to the edge of their limits either.
If it ain't broke, don't try to fix it. Sometimes the best thing we can do for a patient is absolutely nothing. Just because an ambulance was called does not mean we need to find an emergency. If the patient just wants a ride to be checked out at the hospital, so be it atleast let them be comfortable and not unnecessarily straight jacketed to a plastic surf board.
