After quite a lot of thought and some experiences with the vicious downside of the EMT vs Paramedic question, I have reached a conclusion:
EMTs in my system are not responsible for patient care. At one agency, they are literally referred to as "EVOs", or "emergency vehicle operators". That is not to say that they are not involved in patient care, nor is it to say that they do not provide patient care, but they are not responsible for that care. The same is true in most ALS services- paramedics are in charge of what happens on the truck at all times. In many of those agencies, a paramedic must tech the call. This creates an environment that makes it difficult for an EMT to do anything other than EVO and ALS-assist. At my agency, an EMT is literally a talented bag-fetcher, gurney jockey, go-fer and assistant.
Now, I do not agree that EMTs should be limited to these roles. It's bad for professional development, it stifles the growth of critical decision-making, and it breeds an attitude of complacency regarding assessment and care. "They look fine" or "he looks sick" becomes the going depth of assessment, in exactly the same way as a nursing assistant will inevitably learn to recognize diseases. They learn medicine by direct observation, they practice medicine thirdhand with no chance of negative recriminations or accountability, and they do it all on a "vocational" education that wouldn't even let them set up a hoseline in fire school or a curling iron for profit. Despite this, people are smart, and they adapt. They work side-by-side with us, and we respect them as partners and as people. But that's where we hit a snag in this previously-workable relationship.
Many EMTs take this one career further and actively educate themselves, seek out advice from their coworkers and friends, and go to school. They become Paramedics and assume those responsibilities that they previously did not have. Most paramedics, myself included, are in this latter category. We saw what we could do as EMTs, we made a conscious decision that we wanted to do more and perform at a higher level, and we actively sought an education that would allow us to perform at a higher level and do more for our patients, with all of the attendant responsibility. There is nothing wrong with being an EMT with this attitude; they are absolutely vital to our operations as paramedics. A partner who wants to learn is an absolute joy to work with and enhances our patient care immeasurably. A partner who learns how to be a paramedic is not only helping us provide better care, they are providing better care themselves and they are helping themselves progress professionally. This is essentially a master/apprentice relationship by any other name, and is mirrored in other health professions (residents, etc).
On the other hand, many EMTs confuse this with a truly even division of responsibilities. They avoid and ignore higher education and revel in memes, mantras, the perception that EMS is a "family" where we must respect and outright honor the "blue-collar" or "workman" ethic and the noble ignorance of an EMT-Basic. They exist in a world where "everyone has EMT in their certification" or "there's no difference between a white patch and a gold patch". They may have the knowledge base of a paramedic or a doctor or a nuclear physicist, but they are functionally working as assistants. One of the most challenging days of my career to date was when I, as a newly-released paramedic, was informed by my temporary partner that I would be letting her run the calls, because she was "almost a Paramedic, but didn't want to deal with the hassle of upgrading and having to do all of the paperwork." As you can imagine, fellow professionals, this went over with me in exactly the same way as a surgical team would react to a first-year resident declaring that he would be leading the cardiothoracic surgery. These EMTs are everywhere, in every agency. They are "competent" in that they can perform tasks to standard, but they are the first to fall back on protocols, rules-of-thumb, mantras, and pedantic half-answers that equate to a punting of responsibility. They may be able to recount how they saved their paramedic partner from the embarrassment of disconnecting an IV still hanging from the roof or an oxygen line not yet plugged into a portable, but they are not willing to accept real responsibility for patient care, because they have (for whatever reason) not invested in themselves. After all, how much effort and time does it really take to stay current on EMT skills, and why would they invest time in learning why or how when they could say "treat the patient not the monitor" or "BLS before ALS" and simply slide the hard questions to their paramedic?
As a paramedic, I assume that my partners are competent, and I ask them a question at the start of our working relationship- what do they want? If they tell me that they would like to be actively involved in patient care and that they are interested in learning with me, I treat them as if they are paramedics. That is not to say that I let them do things that are out of their scope of practice, but I treat them and their opinions with the same credence and respect that I would hope mine are treated with. I invest time in discussing EMS with them, and I show them what I know about our protocols, equipment and techniques. I explain my actions and ask them genuine questions about what we and I could have done better, and I give real weight to their opinions. I keep criticism entirely constructive, and I often find that I learn more than I have taught. This is how I was treated as an EMT, and I feel like it made me a better paramedic.
If, on the other hand, my partner tells me that they have no interest in progressing beyond being an ambulance driver and an EMT in terms of their practice, they will find themselves doing exactly that. They will drive, they will assist, and they will help assess and treat within their scope of practice. They may learn, but they will not be the recipients of my undivided attention. There is very little point in trying to teach someone who does not want to learn; if I wanted to do that, I'd be teaching in a high school. These are the EMTs who are the first to criticize "discrimination against the white patch" and become defensive about "ambulance drivers", perceived slights against EMTs and who perpetuate the negative stereotypes that abound throughout our industry. Even worse, these same people become paramedics, and they maintain that attitude. I really do feel that these people are the reason that we have problems with issues like appropriate pain management, poor assessments and lackluster patient care.
If someone is determined to remain an EMT, I respect that. I simply ask that they open their minds and learn to the limits of their scope of practice, and not simply revel in ignorance. At my agency, I recently worked with a very, very senior EMT. He expressed a desire to learn more about the ventilator we carry, and I showed him, and I learned quite a bit from him. That is learning. That is the way that things are supposed to work. It was a mutually-beneficial relationship.
There is nothing noble about a patient who suffers because of substandard care at any level. For an EMT to criticize a paramedic when they themselves are unwilling to assume real responsibility is simply foolish.
