I practice by the standards I was taught. Everything I was taught in my training was needed to pass the written and practical exams. It wasn't really my place as the student to say that's wrong, oh you can't do this, or that's outdated, especially at times I wanted to say stop with your field experience stories. Most of the class was irrelevant stories to the current topic that the instructors would always talk about. Anything I said to the instructors would mean squat because of their experience and place in that class.
I am currently out of Maryland. I lived in the deep eastern shore by St. Michael's where I worked as a volunteer firefighter/emt, and then I moved up state and was able to land a gig as a part time firefighter/emt near Annapolis. I have been loving it ever since. My initial plan is to volunteer as a firefighter or emt and keep my certs up wherever life takes me.
If I can ask where the studies are when you said "The whole idea of rapid extrication/KEDs/longboards is being questioned and most studies are showing more harm than good.". It had me thinking because when I was in training to become an EMT one of the instructors said their biggest pet peeves is when they take a patient into the ED after falling down a flight of stairs,or involved with a MVA and the attending tells them to rip all the stabilization off the patient and it putting the patient in danger. Now I am going to go with what the ED attending is saying over what my EMT instructor is saying, unless he or she is a practicing physician. So cutting to the chase, why do EMS providers even bother with stabilizing patients if it may be causing more harm or have to take it all off anyways once the patient gets to the hospital?
For the moment being I am going to follow what I have been told to do, until things change.
