Configuration of Input Forms in EHR Systems Using Spreadsheets, openEHR Archetypes and Templates.

Differences in structure and semantics of data captured using screen forms in different Electronic Health Record (EHR) products and configurations is the root cause of many interoperability problems. We present a workaround enabling reuse of openEHR archetype and template semantics to configure forms in four surveyed, insufficiently standardized, EHR-products used in Sweden (Cerner Melior, Cerner Millenium, Cambio Cosmic and CGM TakeCare). Data from EHRs was then exported and queried using standardized query mechanisms.
