Area of Science:

  • Health Informatics
  • Computer Science
  • Web Technologies

Background:

  • Health-Level 7 (HL7) message semantics enable Electronic Medical Record (EMR) interchange but introduce complexity in Protocol Data Unit (PDU) structure and client-side architecture.
  • Existing EMR systems face challenges in functional implementation and data interchange due to architectural complexity.

Purpose of the Study:

  • To implement a web-based system for efficient Electronic Medical Record (EMR) transaction processing.
  • To leverage Extensible Markup Language (XML) and Java for simplified EMR data interchange.
  • To enhance client-side user interfaceability and server-side functionality for EMR systems.

Main Methods:

  • Utilized Extensible Markup Language (XML) for describing EMR templates.
  • Transcribed XML EMR templates into Hypertext Markup Language (HTML)-Javascript for client-side presentation.

Related Experiment Videos

  • Implemented Java client-server connectivity for server-side message validation, authentication, and database operations.
  • Employed standard web client-server mechanisms for EMR transaction processing.

    • Main Results:

    • Developed a web-based system for EMR transaction processing with an XML-based template structure.
    • Achieved client-side user interfaceability and server-side functionality using standard web technologies.
    • Enabled secure EMR interchange over the internet via Java-based authentication and data privacy mechanisms.

    Conclusions:

    • The proposed XML and Java-based approach simplifies EMR transaction processing and data interchange.
    • Web-based EMR systems can be effectively implemented using standard web technologies, enhancing accessibility and security.
    • The system architecture facilitates efficient handling of clinical and administrative EMR data.
