Not sure where “and nurses” is coming from in your comment. Nursing research is predominately on long-term patient outcome, whereas MD education is predominately on the disease / underlying cause. The nurses I know are more focused on and better educated on how holistic care serves the long-term outcomes of the patients, while docs are better educated to attend to the acute problems.

I would expect a change to quality of calories provided in a hospital to originate from a DNP before a MD.

It is coming from exactly what you said, I would also expect a change to nutrition to originate from a DNP. My point is they have more control over day-to-day intake.
