It is pretty ignorant for people to say one person can make a "diagnoses" and another person cannot. Confirmation is of course required though. But who does the testing? The doctor will order the test, but a technician will do the actual testing. The doctor or whom ever will look at the results that confirm the tests. If a person comes into the ER complaining of, lets say chest pain. Labs are drawn up by a lab tech or ER tech. Those blood samples, are taken to the lab, where the lab technical will run tests on them. They are run through a computer and the results are printed. What diagnoses did the doctor make? None if you ask me. The computer did.
For those who are out in the field, doing pre-hospital care. I could not agree with ERDoc more. FOR THE MOST PART, paramedics are not morons. We are educated and trained very well. People will argue with the education issues on how long a certain program is. I am sorry so say, but it's not the schools fault for what you don't learn. Education in medicine is what you put into it. You are in a highly professional field where peoples lives are at stake. If you don't have the maturity to LEARN ON YOUR OWN, and not be spoon fed information, maybe this isn't the field of work for you. ERDoc, and all others, I am not saying that is what you were trying to say, those are my words and my opinion.
We often come across patients in the field who are having difficulty breathing. We don't just slap on an o2 mask and blindly gives medications to these people. We assess them. We listen to lung sounds, we do a 12 lead, we do capnography or sp02 at the very least. We ask questions, we check their medications, etc etc. We form an an educated "guess" if you will on what is going on with this patient, and we treat them appropriately. What much else can the doctor at the hospital do? Aside from ordering an x-ray and looking at it to confirming what the x-ray tech already knows, but isn't allowed to "say" what it is, and ordering lab work. The nurse already knows what tests should be run, and usually has them ready to be drawn up before the doctor can "order them".
All that being said, doctors, nurse practitioners, physician assistants are ALL a very important part of the profession. They are all highly trained and educated, as well as every other hospital/ems employee responsible in patient care and testing. I am not putting down any position or level of care. We all have our place. Saying one person can say "ok you are sick" just because they have more schooling, is just silly. Everyone should know what is going on with their patients to a certain extent.
