For those advocating the "professionalization" of nursing, it seems they would welcome the transfer of skilled tasks to other personnel. And the nurse's function would then more specifically be care coordination: getting the overall "big picture" and making sure all the various staff are doing their part to assist the patient towards the healthcare goal.
Of course, hospital nurses have always done this to some extent. However, the bottom line was that nursing staff took care of hygiene needs, administered routine treatments, and were the eyes and ears for the doctors, recording assessments and judging when back-up was needed. Basically, nursing was the patient care that the doctor didn't do and the family didn't do. That demanded a breadth of knowledge and skills, both medical and interpersonal. Nurses, having so much patient contact, were in an ideal place to see the "bigger picture" - to advocate for patients to doctors, social workers and the like.
As medical technology has grown and inpatients are generally sicker, there are more and more tasks that need to be done. Nurses are left running to get the tasks done but still expected to somehow be the patient advocate that they've traditionally been. So the assistance in tasks from other healthcare personnel can help ease the physical demands of the nurse. However, it was the carrying out of these sometimes mundane tasks that allowed the nurse to interact with the patients and get that "big picture" that helped them be such skilled caregivers and patient advocates.
With new medical procedures and technology multiplying, with ever shorter patient stays, with several care providers working on just their own specialty area, nurses are still expected to do whatever it is that no one else is doing as well as ensure that everyone else is on track as well (check for doctor errors, pharmacy errors, dietary errors, make sure the social worker or discharge planner is on task, and of course supervise any auxiallary staff working directly under the nurse).
I can see how some see "professional nursing" as moving away from direct patient care and more to care coordination. However, that leaves us with a problem. Nursing traditionally has meant direct patient care. If you take care of a loved one at home, we call it "nursing." Someone will still be performing the direct patient care, and who will those people be if not nurses? Will traditional nursing then be done by "patient care partners" "physical therapy aides" and "medication administration techs" ? Even if we define nursing of the future to be predominantly care coordination and less direct patient care, will we as a society be able to make the jump in our image of what nursing care is? Perhaps hospital nursing as we've known it is a thing of the past and we ought to think of a new name for this evolving nurse so as to avoid confusion both within and without the profession.
