If you have have standards they have to be across the board, curtains are not acceptable,you cannot control infection with curtains, sliding doors or close the unit, this is were I said there will be a lot of opposition. Us biomeds when we met with the electrical engineers asked for only one supply either choose 110 or 220 but got out voted. It is not just MODA, there are a lot of private hospitals who regard themselves as A class when in fact they are well below normal standards and they will fight as it will cost to put things right. Patient first, money second.
