Oh my god how is this a problem in the modern age?
The modern age? 100 or even just 50 years ago hospital wards were run by "matrons", fierce and experienced nurses who ran their wards like a Sergeant Major inspected a Guards regiment, everything immaculate. That system was scrapped in favour of what we have now, a fluffy blame-free culture where no-one is responsible for anything. The problem of failing to maintain standards is entirely a "modern" one, sadly.
