Detailed Clinical Models

As the PCAST Workgroup ponders the meaning of a Universal Exchange Language and Data Element Access Services (DEAS), it is exploring what it means to exchange data at the "atomic", "molecular", and document level.   See Wes Rishel's excellent blog defining these terms.

For a sample of my medical record using one definition of an atomic form, see this Microsoft Healthvault screenshot.   It's clear to me that if we want to exchange structured data at a level of granularity less than an inpatient/outpatient/ED encounter, we need to think about detailed clinical models to specify the atoms.
