Yesterday my emt partner and I responded to a BLS transfer, a home discharge from med/surg in a local hospital. Dispatch originally said the call needed a wheelchair/gurney van for the pt, "or whatever closest unit". So we show up on scene, get a set of vitals and I take report from the nurse. Nurse hands me paperwork and PCS. PCS states pt needs a wheelchair van for transport. I go in and introduce myself to the PT, upon visual assessment, I find the PT is a left leg amputee below the knee cap. We were informed the PT had 3 flights of stairs he had to go up. So we talk to the nurse and get her to rewrite the PCS and have dispatch upgrade the call to BLS since we will need to utilize a stair chair. Also it was now BLS because pt wouldn't be able to safely sit upright during transport and he was AOx3, his deficits were unable to tell time of day. We were explaining to the nurse why this call needed to be BLS and not a wheelchair van call. Nurse asked us if we could just lift up the gurney into the PT's home with him on it. My partner and I looked at each other. "Negative Ma'am we cannot lift that gurney up by ourselves". I don't want to be rude but come on..
