Valuable but not a priority, it should be

Very good to see this included in ISA, the prevalence of obesity and Type II diabetes has a huge impact on health care and patient population quality of life.

As previous comment states - voluntary is not going to see this adopted. 

Been there, done that, doing…

Been there, done that, doing it again for the umpteenth year in IHE. It isn't hard, but adoption is low because there's not a significant incentive for use of any standards to do this in light of other mandates (you can call CEHRT/MU/MIPS a voluntary program but, let's be realistic here).
