It means someone could in theory create a vertically integrated alternative to the entire field of medicine rebooted from the ground up with more modern understandings of things like statistics (e.g. Bayesianism) and more efficient bureaucratic constructs, and it'd probably be considerably better than what we have.

I say in theory because this would cost a rather large fortune and would probably be illegal in most nations, so it's not likely to actually happen.

Well you gotta pinch your doctors nose while inserting a paper clip in his ear and wait thirty seconds. Factory reboot

It means doctors no longer have to wash their hands prior to a trepanning.
