In a recent blog posting, Doug Fridsma, M.D., of the Office of the National Coordinator for HIT gives an update on efforts to develop standards for the exchange of health information. And he makes clear the standards won't be optional. "Reducing optionality improves interoperability and lowers the cost for vendors to implement, thus lowering the cost for health care providers as well," Fridsma writes. "ONC is identifying the vocabularies, the message, and the transport 'building blocks" that will enable interoperability. While vendors should be able to flexibly combine them to support interoperable health information exchange (HIE), these 'building blocks' need to be unambiguous and have very limited (or no) optionality."
