Good point, if you were trained and confident to exert as a paramedic level and the company wouldn't allow you, then the person would naturally move on to another company where he/she could practice to the full extent of their capabilities
But if you do not demonstrate the competencies necessary to work as a Paramedic or have the attitude that you can play by your own rules, the company does not need to have you as a Paramedic.
Being granted the ability to function at a level requiring more responsibility is a privilege and not an entitlement because you have a pretty patch.
In Florida, you can work a BLS truck while wearing a Paramedic patch but you will only stay within the scope for that truck. You can do an "ALS" assessment and request for an ALS truck if you feel it warrants. In Florida, you can also go from Paramedic to EMT provided you meet the requirements to wear that patch. You may be asked to take the NREMT if you haven't in the recent past.
We have seen examples of were Paramedics that didn't meet their competencies go to the scope of an EMT in Washington, D.C. We have also seen a FD be stripped of their ALS privileges in Collier County until they could prove they were competent enough to be trusted with ALS medications and skills.
EMS has an opposite mentality of other medical professions. In EMS, the tech school mentality means every one is competent to perform certain technical skills and that patch gives them the right.
In other professions, they must demonstrate their abilities through knowledge, credentials, experience and initial competencies as well as expected level of competency to be maintained. Other professions also tell those that can not make the grade in their level of patient care to move on with some even being taken out of the patient care area totally. There are some in EMS that also place patient care as the priority. FF/Paramedics may go to being just EMTs as FFs. There have been Paramedics become just drivers for Specialty teams or inventory specialists.
I can also give you examples of people who hold two licenses that can not function at the level of the higher license in some situations. If I am working on CCT as a Paramedic that does not allow them to do IABPs but I have expertise at transporting IABPs as an RRT, an exception can not be made because I am not working as an RRT on that truck and it does not have the P&P from the medical director to back up his/her Paramedics doing IABPs.
If an RN who holds many years of experience in a high acuity ICU with the credentials of CCRN of many specialties, MICN and CEN became a FF/Paramedic with L.A. County in California, his/her scope of practice would be that of an L.A. County Fire Paramedic. The skills and advanced scope of practice he/she had as an RN would not be used on the Paramedic job but could still be used for a part time job.
We also had the problem with Paramedics who took the mail order nursing program Excelsior and passed the nursing board exam. They had the credential of RN but could not get licensed in their own state because their education was not recognized due to the lack of clinicals. If they could get licensed they found that the job market was not there for someone who could not pass competencies for basic nursing skills and a working knowledge of nursing theory. As well, a Flight Paramedic who becomes a licensed RN may not work as a Flight RN with the same company until all requirements are met such as 5 years of hospital ICU experience.
Another example, if you get hired for the position of ER Tech because your Paramedic cert showed proof of some medical training, that doesn't mean you will be functioning under the scope of a Paramedic and do what you were doing on an ambulance.
