Evidence-based practice

I am doing an Evidence-based practice where my POI is decreasing the number of children being diagnosed with diabetes by combatting the number one cause which is obesity.  The question asked… What change I WOULD LIKE (Key) to implement in my practice I chose to do the question below. I need help on how to use the Lewins change theory to accomplish that…

how can I use Lewin’s change theory to implement a change in the screening age for diabetes type 2 to age 5 from the current recommendation of age 10 or the onset of puberty in my clinical practice as a future FNP????

Thanks for your help
