Also, move the darn patient to the bed, then start talking. Or do it at the same time. But when the medic sits there talking while 20 people are waiting for the patient to be moved to start treating it makes us a bit nuts.
oddly enough, our trauma attending wanted the exact opposite. He insisted a report be given by EMS to the trauma team, and only after everyone had no questions, could we transfer the patient to the trauma bed, and they would go to work. apparently the doctors and nurses wouldn't pay attention to the EMS report if we transferred the patient to the bed and then get a report.
Would drive me nuts, because it delayed our turnaround time, and it delayed my cleaning and stocking time, which kept me in the ER longer that an EMS crew should, especially with calls holding (and no, management frowns on using mutual aid).
I would rather drop the patient off, take the cot and start cleaning and restocking, while my partner gives the report and let the trauma team go to work. but the trauma MD's don't want it that way, so we did what they said.
As for the OP's question, on a sick/critical trauma patient, everything comes off, and they patient is covered with a sheet. on a non-sick trauma patient, leave underwear on assuming it doesn't interfere with assessment. if it interferes, than off it goes.
Also, if they can't take it off themselves, or it hurts too much for them to take it off, and I need it off, than snip snip it goes. also remember, just because you are helping the patient out by not cutting their clothes in the truck doesn't mean the ER won't snip it all off when they get onto the hospital bed.
