My late mother-in-law was hospitalised in Liverpool a few years ago. We couldn't visit every day due to the distance, but whenever we did we found she wasn't being fed by the nurses. They'd leave her tray of food, then collect the untouched food later thinking she wasn't hungry. In fact she was unable to feed herself. Much complaining later the problem was resolved. But without our intervention she could have starved to death.
I think it's called stupidity (or lack of nouse or training).
