Architecture and tools for open, interoperable and portable EHRs

Area of Science:

• Health Informatics
• Computer Science
• Distributed Systems

Background:

• Electronic Health Record (EHR) systems are central to modern health information systems.
• Current EHR systems face challenges with interoperability due to complexity and platform constraints.
• Shared care information systems necessitate advanced interoperability solutions.

Purpose of the Study:

• To introduce a generic component architecture for health information systems.
• To address the need for high-level interoperability in shared care.
• To ensure EHR systems are independent of technical complexities and localization.

Main Methods:

• Utilizing the ISO Reference Model--Open Distributed Processing views for system design.
• Adopting the Model Driven Architecture (MDA) paradigm.
• Developing platform-independent reference and domain models.
• Employing tools for automatic transfer to platform-specific models.

Main Results:

• A generic component architecture for health information systems has been established.
• The proposed architecture facilitates high-level interoperability.
• Platform-independent models are specified and harmonized.
• Automated transformation into platform-specific models is achievable.

Conclusions:

• The generic component architecture enhances the usability and adaptability of EHR systems.
• Adherence to ISO Reference Model and MDA principles is crucial for interoperability.
• This approach supports the development of robust and maintainable health information systems.
• The methodology enables seamless integration across diverse technological environments.
