This study introduces a secure system for sharing patient health information using Health Level Seven (HL7) standards. It enhances data security for electronic health records, improving healthcare quality and resource management.

Area of Science:

  • Health Informatics
  • Computer Science
  • Medical Information Systems

Background:

  • Quality medical treatment relies on shared patient data and efficient resource allocation.
  • Computer-based patient records are crucial for effective clinical data interchange.
  • Health Level Seven (HL7) is a widely adopted standard for healthcare data exchange.

Purpose of the Study:

  • To develop a secure system for clinical data interchange using HL7 standards.
  • To address security concerns in transmitting patient health information over networks.
  • To create a safe delivery channel for electronic health records.

Main Methods:

  • Implemented a security handler within the HL7 architecture.
  • Utilized international security algorithms, models, and policies.

Related Experiment Videos

  • Developed a secure interchange environment at the application layer of the ISO/OSI model.

    • Main Results:

    • Established a secure channel for HL7-formatted clinical data.
    • Enhanced the security of electronic health record (EHR) data interchange.
    • Provided a solution to overcome shortcomings in clinical data exchange.

    Conclusions:

    • The developed security system effectively enhances the safety of HL7 data transmission.
    • Integrating security measures into HL7 architecture is vital for protecting patient data.
    • This system supports the growing interest in HL7 as a standard for clinical data interchange in Taiwan.
