I have been very rural, and urban in my experiences. That did not change my treatment. It does, however, depend on the patient. If the patient is critical, I am getting them packed up ASAP (not including initial assessment of course). For example, if the patient is feeling weak, having minor difficulty breathing, I am not going to rush them out of their house and into the ambulance. I will treat them in their home and calmly get them packaged up for transport. Now, if they are having crushing chest pain, BP is crap, they look like crap, monitor looks like crap, I am not going to pussy foot around with them. They are load and go. I will treat them en-route.
Now for most cases where your patient is a few blocks from the hospital, personally, I'd like to have my patient going into the ER with SOMETHING done for them, and have it looking like I know what I am doing. During clinicals, I HATED seeing a patient being brought in, and all the EMS crew could tell us was a chief complaint, no medical history, no treatment, not even a good set of vitals. Just "HERE YA GO SEEEE YA!".
I have had a patient, where we were dispatched from the hospital (we were just dropping a patient off) and literally, ACROSS THE STREET from the ER, was the address. We walked across the street, called responding, on scene, at patient, enroute, at hospital, all at the same time. The patient fell over, twisted their ankle, and wanted to see the Dr. We put her on the stair chair, put on an ice pack and roller her across the street.
Why people want to load an go everything, is beyond me.
