Patients treated in hospitals with highly educated nurses providing direct patient care have higher survival rates and lower risks of complications.
Unfortunately NHS hospitals prefer to hire care assistants (very different from nurses). The few nurses on staff for a ward are responsible for everything for every patient whether they have 3 care assistants or 20 on duty with them.
As a Nurse to 6 patients you will be so overwhelmed with IV's, treatments, assessments, meds, trouble shooting and interruptions that you will be dealing with that stuff every minute of every hour. This is the case if you have 1 care assistant helping or 10. If you miss a change in condition or get a drug up late because you went off to help a care assistant with a bath you will be hung.
And even if you weren't overwhelmed with fire fighting there is no way you can provide basic care to everyone you are responsible for. It is impossible. I was a care assistant once. I thought that the nurses were dumping the basic care on me because they didn't want to be bothered. OMG NOW I UNDERSTAND!! I didn't back then and have gone back to apologize.
On average NHS staff nurses are 1 nurse to 10 patients and up on a general ward. More like 1 to 15.
These days patients are much more acutely ill, the stakes are higher and there are actually less real nurses and more untrained assistants on the wards thanks to managers wanting to save cash. Management isn't dumb. They know that the public is stupid enough to see 5 women in uniform on a ward and think that the shift is staffed with five "nurses". The public seems to use the word nurse to identify anyone who works in health care helping patients. That is really messed up.
Here is the research regarding degree educated nurses. Not to put down diploma nurses. Their course is very intense and turns out good nurses too. You will have to scroll down a bit.

Caring and empathy is great but not enough to make a good nurse. I know many caring and empathetic nurses who got people killed because they didn't think.
