"It ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things. Because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them." Niccolo Machiavelli
I agree with Machiavelli, on more accounts than this here.
However, the reason hospitals in the US are pulling field lines and hospitals all over the world pull lines when a patient gets to a floor or ICU fall under the realm of preventable infection. (or reasonably preventable)
Field resuscitation techniques, surgical or otherwise generally fall under "acceptable risk of infection" for the preservation of life and limb.
I would also call attention to the fact that infections caused by community organisms are far easier to treat than those found in the healthcare setting, particularly in surgery and intensive care.
The organisms there are the survivors of the fittest.
