Implementation of a secure and interoperable generic e-Health infrastructure for shared electronic health records...

Area of Science:

• Health Informatics
• Computer Science
• Medical Technology

Background:

• The widespread availability of medical data can improve healthcare quality and reduce costs.
• Patient-centered shared electronic health records (SEHRs) require standardized, distributed data provision.
• Integrating the Healthcare Enterprise (IHE) facilitates cross-institutional data exchange, but holistic implementations are rare.

Purpose of the Study:

• To share experiences and lessons learned from five years of developing and implementing IHE-compliant products for SEHRs.
• To address the limitations of existing IHE Integration Profiles regarding security and privacy regulations in holistic eHealth infrastructures.

Main Methods:

• Utilized IHE Integration Profiles, including Cross-Enterprise Document Sharing (XDS), Patient Identifier Cross-referencing (PIX), and Patient Demographics Query (PDQ).
• Implemented an Audit Trail and Node Authentication (ATNA) Integration Profile for secure interaction logging.
• Developed high-level components and software products for a cooperative care infrastructure based on IHE standards.

Main Results:

• Developed holistic, secure eHealth infrastructure components and software products based on IHE Integration Profiles.
• Successfully implemented an IHE XDS Affinity Domain in Tyrol, Austria, providing practical evaluation.
• Identified and documented key lessons learned during the development and deployment process.

Conclusions:

• Holistic IHE-based eHealth infrastructures can be realized to support SEHRs.
• Practical implementation highlights the importance of addressing security and privacy comprehensively.
• Lessons learned provide valuable insights for future development and deployment of IHE-compliant systems.
