Restructuring an EHR system and the Medical Markup Language (MML) standard to improve interoperability by archetype...

Area of Science:

• Health Informatics
• Computer Science
• Medical Informatics

Background:

• An early electronic health record (EHR) system was developed in 2001 for regional healthcare information exchange and patient data access in Japan.
• The original system, built on a legacy platform, faced challenges with maintenance and updates, hindering its ability to meet evolving clinical requirements.
• A Medical Markup Language (MML) standard was developed concurrently to facilitate inter- and intra-hospital communications.

Purpose of the Study:

• To reconstruct the legacy EHR system to enhance maintainability and reduce costs.
• To improve the system's flexibility and ability to adapt to new clinical requirements.
• To ensure continued semantic interoperability through the adoption of archetype technology.

Main Methods:

• Reconstruction of the EHR system utilizing archetype technology.
• Implementation on the Ruby on Rails platform.
• Generation of MML equivalent forms from archetypes.
• Deployment as a cloud-based system for regional EHR use.

Main Results:

• The reconstructed EHR system demonstrates enhanced flexibility compared to the legacy system.
• The new system effectively maintains semantic interoperability through archetype technology.
• The cloud-based deployment facilitates preliminary use and future scalability.
• The system is now better equipped to adapt to new clinical requirements.

Conclusions:

• The reconstructed EHR system, leveraging archetype technology and a modern platform, offers a more flexible and maintainable solution for regional healthcare information exchange.
• The use of archetypes ensures semantic interoperability and facilitates adaptation to evolving healthcare needs.
• The cloud-based architecture supports efficient deployment and future enhancements for regional EHR initiatives.
