I observed in November last year that excess hygiene in hospitals was probably just as bad as insufficient hygiene. The problem is that washing hands religiously and removing most bacteria just leaves a huge space for those left behind to multiply. Given that the ones left behind are likely to be the nasty, hardy, scary ones, this is a problem.
The recommendation, only half humorously, I gave then was for doctors to wash their hands in yoghurt.
Regardless of the solution, whatever we're currently doing still isn't working: Iain Dale has a story of another patient killed by MRSA, courtesy of the NHS.
