The Office of the National Coordinator for Health Information Technology (ONC) just released what it calls “A 10-Year Vision to Achieve an Interoperable Health IT Infrastructure.” The directive generating the most attention calls for “a common set of electronic clinical information…at the nationwide level by the end of 2017.” According to ONC, the common data set would consist of about 20 basic elements, such as patient demographics and lab test results.
At first blush, the ONC directive is a small step in the right direction, but sets the bar awfully low. Rest assured that vendors will consider 20 basic elements the maximum data set, not the minimum. A more effective approach would, for example, specify vocabularies (LOINC, RxNORM), document types (JSON, XML) and transport mechanisms (HTTPS or other TLS) to be used when sending or receiving data instead of focusing on the data elements themselves.
