Moving forward, you are seeing ACO's adopting centralized purchasing for all members of the ACO. Supply chain management now has tremendous power within a delivery network.

Product standardization, volume purchasing power, and volume discounts will play even more of a role as we move forward. Supply chain management is where the power is.
