Nurture and nursing

The word of the day is "nurture".  Maria Shriver said it tody, but I have been thinking about this.  It came up, as I recall, in the conversation about creation of jobs, and it reminded me that it is important to think of nurturing a lot of things -- like jobs, like companies, like the health care system, like the economy.  And it came up in the context of Shriver and her team releasing a major report on the situation of women in the U.S. of 2009.
 
The "health care" system in the US does not feel like it is based on a nurturing impulse or motivation.  I wonder if it would be improved by putting more emphasis on a relationship betwee patient and nurse, rather than patient and doctor.  Is it possible to create a layer of nursing such that they know and work consistently with persons and families.  They could have a layer of doctors (GPs) to call upon for problems that go beyond normal nurturing care, and they in turn could call upon specialists, as today.
 
Would something like this need legislation? Maybe just a shift in perspective that recognized that human services (like health care) are more amenable to the nurturing mindset than they are to, say, the industrial paradigm.
