That is why I put "discovering and disseminating best practises" in there. We can all guess what the best way of specifying and implementing the standards is, but why not experiment and find out? This ranges from the setting of the standards (eg how detailed they are), through how they are implemented. And of course all the other things (eg reducing hospital infection rates, improving overall hearth health).
