What happens when you version the standards for P2P exchange? One of the key value propositions of "HIE the noun", for example an Enterprise Service Bus (ESB) based regional patient-centric exchange, is that it abstracts between data providers and data consumers. Thus, if a new standard comes along, some can implement it and some can hold off. The HIE provides the abstraction between the two. There is no tight-coupling between trading partners. In the "we will all do the same thing peer to peer" model, doesn't it break when something new comes along? Otherwise, every P2P end-point needs to support every standard that emerges as they emerge and until everyone has it implemented, the world is frozen. That sounds an awful lot like where HIT is with ICD10 right now. Most systems seem to have tightly coupled to the ICD9 codes rather than having an abstraction in their system between internal coding and the outward facing standard codes, now they have trouble upg
