Actually there has been talks for at least 5 or 6 years now in the US to promote our form of medicare/medicaid based on results and not on services performed.

There will be two factors on this kind of pay system:
A.) Results
B.) Patients' feedback

The insurance company is strongly pushing this because believe it or not they are losing money since Obamacare.

This will allow alternative treatments like chiropractors, naturopath, functional medicine or acupuncturist prove that prescribing drugs is not the only way to cure diseases.

The only reason why we haven't seen any movements in this is because sadly it hasn't been proposed to the congress.
