This is why as EMS professionals we need to prove our professionalism and fight for better pre-hospital care. The more we can do pre-hosptial, the better the patient.
I agree with all else you were saying, which is kind of what my rambling was going towards. We are also expected to be enroute to the hospital within 10minutes of arriving on scene. A lot of the time, this is quite possible. I like to do my assessment on scene, vitals, IV, BGL, etc etc. It doesn't take long. But again, this is all situational and depends on the patient. Sometimes you can't sit around.
Rushing yourself through things is no good for anyone, especially the patient. The more you rush, the more you will forget to do. Taking your time TO A CERTAIN EXTENT is always how I operate. If it takes me a minute or so longer to package a patient, so be it.
There have been times when I was a student.. where we would be on scene for 30mins. The medic wanted to do everything short of a CT scan on scene. There have been other medics where if you attempted to start an IV on scene you were told to stop and go wait in the ambulance. Everything was done in the ambulance, usually when it was moving. This, I did not totally agree with in most circumstances. I was told "we have to get them to the hospital quickly before time runs out"
