Achieving semantic interoperability in electronic health records (EHRs) requires consistent clinical meaning representation. Addressing challenges in EHR data sharing is crucial for safe computational interpretation of integrated clinical data.

Area of Science:

  • Health Informatics
  • Computer Science
  • Clinical Data Management

Background:

  • Electronic health records (EHRs) contain vital clinical data.
  • Seamless and meaningful sharing of EHR information, known as semantic interoperability, is a significant challenge.
  • Computational services require safely interpretable clinical data integrated from diverse sources.

Purpose of the Study:

  • To describe challenges in achieving semantic interoperability for EHRs.
  • To present the clinical case for consistently expressed clinical meaning in EHRs for computer processing.
  • To outline information and knowledge artifacts used in EHRs for meaning representation.

Main Methods:

  • Analysis of sustainable architectural approaches for EHRs.
  • Exploration of information and knowledge artifacts for representing clinical meaning.

  • Investigation of challenges in consistent terminology use with EHR reference models.
  • Examination of implications for EHR archetype design.

    • Main Results:

    • Diverse options exist for representing compound clinical expressions.
    • Inconsistent terminology use with EHR reference models poses problems.
    • Limitations of current information and knowledge artifacts for meaning representation are identified.

    Conclusions:

    • Minimizing diversity in EHR record structures and terminology systems is essential for semantic interoperability.
    • Recommendations are made for changes in record structures and terminology to improve EHR data sharing.
    • Consistent clinical meaning representation is key for safe computational processing of EHR data.
