Of course working as an EMT would help you if you want to become a paramedic. You can debate how important it is, but to claim it has NO value is being dishonest..
I can't speak for everyone, but for myself, and I imagine for others, when we speak of EMT experience as being worthless before becomming a medic, we are talking about the educational curriculum and the ability to apply the theory that is taught to the street. (because there is a total absence of theory in the effort to preach skills)
It is not that being proficent in any particular skill isn't helpful or useful, but without understanding theory, short cuts, "the street way," and room for other bad habits and faulty decision making can develop.
In an adult learner, it is exponentially harder to unlearn and relearn. I therefore subscribe that practicing skills without theory or knowledge potentially creates complications that exceed the benefit.
As for driving. a growing body of evidence is demonstrating the use of emergency drving procedures (aka lights and sirens, increased speed, ignoring traffic signals, etc,) has very little effect on patient outcome and a very large effect on injury to providers and the public, both directly and wake effect.
I have posted over years, that patient care, not delivering people to the hospital needs to be the focus of EMS. I realize that in certain cases only a hospital has the resources needed, but it in no way justifies the danger that has been the status quo for so long.
If weather or road conditions require an experienced under stress driver, then in the interest of safety, the stress needs to be removed. The lights and sirens need to be shut off, the speed needs to be absolutely as safe as possible, and normal traffic signals should be obeyed.
If that means the occasional patient dies or is further disabled to protect both the providers and the public, then that is what needs to be accepted.
Unequivocally if a provider injures or kill somebody else trying to help another person (especially if for better or worse speed will not make a difference), they are not useless, they are a menace, and should be removed from service immediately.
