Unfortunately, it is a reality check. This is where I get frustrated with educational systems not informing incoming students of real life. The chances of performance on delivering emergency care as what was taught is a rarity, not a common daily basis task.
This is not meant to be demeaning, but we rise expectations of students only later to have them totally leave the profession because it is nothing like we taught them. Rather, we should be teaching "in case" situation(s). Fortunately, more and more EMS is becoming advanced. This is (as you pointed out) better for the patient and better for the system.
Everyone has to begin at some point, but very few realize the vast numbers of Basic EMT's in the U.S. My rural state alone has over 5,000 Basic EMT's. Now, the problem is there is < 200 EMS. Like every other state, where does this leave the Basic?
Unfortunately, majority soon realize the expectations and reality is quite a different thing. This is where I would wish the curriculum would change. Yes, there are non-emergency transport systems that many work at until either they can get hired by an 911 provider, increase education or burn out.
We (EMS) have reached a point of dilemma like other professions of having too many and not enough in certain regions and areas. This is why I endorse more entry level requirements and better information of the EMT profession, before allowing anyone entry into any EMS classes. Like all other healthcare profession educational systems, it should be based upon supply and demand ratio.
I wish the best of luck, and hope you continue to pursue increasing your EMS knowledge. As you increase your level, you will be able to perform more at the level you were educated at, alas until we flood the market on this as well...
