I have been a "Harris Poll-ee" for several years and I don't really recall getting the Nurse trust poll. Anyway.........
Here is a site for the National Research Corp. that has a presentation by state for Health Care and Nurses, insurance plans etc.
You do have to register but it's free and they don't really want anything.
I found that in my "market" the hospital I worked at was third in public perception of nurses "quality."
