Hospital Superbugs

I notice there is a lot in the news at the moment about superbugs in hospitals. This is quite a simple and easy problem to solve – clean the hospitals properly!
It seems the hospital trusts and their chief execs seem oblivious to this concept. As long as they can cut costs left right and centre and keep their huge salaries and benefit packages then it's 'I'm aright Jack'. But the best bit is that the high ups seem to make an utter pigs ear in one area, then move on to another and do the same. What are they and the people who employ them thinking?????
