Actually, it is highly networked. Tom Clancy with Mark Greaney wrote about this very thing. Sure, there were some fairly far reaching parts in the book (Threat Vector), but the basic premise was how difficult it would be for the military to fight a war without the network it is so massively dependent.

Yeah, somebody pulled that out of their arse. Healthcare professionals rarely have a clue as to what someone's organ donor status is, then when the person is or near brain death it is the state/regional organ donor organization that makes the decision what can, if anything, be harvested. The hospital has no say.
