Patient matching—the ability to match a person to their correct medical record—is a perennial issue in health IT.

More than a year after the first draft of the Trusted Exchange Framework and Common Agreement (TEFCA) was published, the Office of the National Coordinator (ONC) for Health Information Technology (HIT) is back with a second draft.

 Previously, in “TEFCA: A beginning for nationwide interoperability ,” we discussed the basics of the Trusted Exchange Framework and Common Agreement (TEFCA), an ambitious plan assembled by The Office of the National Coordinator for Health Information Technology (ONC) to provide an “on-ramp” to nationwide interoperability for healthcare data.
