@Germlat,
"Are infection control processes truly efficient?"
"but is it cost effective?"
MRSE either is a problem in a healthcare facility, or it is not. The number of cases in a facility is not particularly indicative of poor sanitation, as it is in the persistence of the strain.
IMO, the effectiveness of control processes is acceptably high, (except if you know of someone infected, than they are horrible).
The same mindset goes for the budgeting fighting MRSE. It's a case of, "The squeaky wheel gets the grease."
The 'awareness' along with the time and money spent on breast cancer, is far atop the list for preventable deaths - but it's ninth in the order of causes.
What can I say? People like breasts more than colons - and so it goes.
