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.
