My first add certifications have lapsed, a situation I need to remedy, but what do the Red Cross, etc., say about QC? Any discussions about use/missuse in the medical or emergency literature?

I would be willing to guess that QC is not a panacea or even your first strategy of choice, but that it indeed has its place.

Most of what I have dealt with is blunt force trauma, the result of stumbles and falls in the back country - only a little penetrating trauma - perhaps only two or three gunshot wounds. My experience is alos biased, most likely, because the really bad trauma cases bled out before we could reach them....
