When I worked in hospitals there were: State Enrolled Nurses, whose job it was to maintain the patients' comfort (nourished, clean, comforted), State Registered Nurses who dealt with drugs, injections, IV, catheters etc., and a Ward Sister/Charge Nurse who had overall responsibility for patient care.
It worked well. The SENs did not need high expensive levels of training and did a very valuable job that was hugely appreciated by the patients.
The race to make all nurses graduates has not helped things - the jobs that used to be done by the SENs seem to be no-one's responsibility, and in the latter years I had many relatives worried sick that their loved-ones were not getting nourished even, as food was just left by their beds out of reach and no attempt made to ensure they had a way of ingesting the food. These were mainly head-injured people or those who had had strokes.
It really was the good old days cliche - the presence on the wards of folk from private companies with no personal commitment to the hospital just exacerbates the problems - cleaning, feeding etc. are all farmed out now.
