Overview
ISO/TS 27790:2026, Health informatics - Document registry framework, is an International Organization for Standardization (ISO) Technical Specification that defines a comprehensive framework for managing, transmitting, storing, and utilizing clinical and personalized health documents. The standard is applicable to a broad range of healthcare environments, supporting interoperability among various healthcare specialties such as laboratory, cardiology, and eye care, as well as areas of personalized health. The framework is designed to enable effective health information exchange by providing mechanisms for shared document registration, retrieval, and discovery across diverse health organizations and information systems.
By leveraging established health informatics standards (such as HL7 CDA, HL7 FHIR, and DICOM), ISO/TS 27790:2026 avoids introducing new standards and focuses on harmonizing and optimizing existing technologies for document sharing, both within and across organizational and regional boundaries.
Key Topics
- General-purpose document registry framework: Supports clinical and personalized health information exchange by enabling storage, indexing, and controlled access to a wide variety of health documents.
- Support for federated registries: Facilitates Cross-Community Access (IHE XCA), allowing users to find and retrieve documents from multiple interoperable registries while minimizing risks of unauthorized data exposure.
- Flexible content support: Manages documents of any standardized health content, whether structured (e.g., coded summaries, numeric lab results) or unstructured (e.g., scanned forms, images).
- Interoperability and scalability: Built on proven integration frameworks, such as IHE XDS, IHE MHD, and IHE MHDS, incorporating modern approaches through HL7 FHIR for mobile and web-based access.
- Security and privacy readiness: Includes provisions and references to related IHE profiles (e.g., ATNA for audit trails, BPPC for patient privacy consent) to support privacy, security, and patient identification requirements.
- Modular architecture: Leverages modular actors and services for registry, repository, document source, and consumer roles, which can be implemented in centralized or federated deployments.
Applications
ISO/TS 27790:2026 delivers practical value for healthcare IT architects, policymakers, and providers through these key application areas:
- National and regional health information exchanges (HIEs): Provides a standardized infrastructure for sharing electronic health records (EHRs) across clinics, hospitals, laboratories, and specialist practices.
- Federated health networks: Supports interconnection of independently managed document registries, enabling cross-community access and consistent patient information retrieval.
- Mobile health applications: Facilitates mobile and web-based sharing and retrieval through integration with IHE Mobile Health Document (MHD) and Mobile Health Document Sharing (MHDS) profiles, using HL7 FHIR standards.
- Patient-centric health management: Enables patient-controlled health record access, empowering consumers to manage and share their own health data securely.
- Specialty document exchange: Supports exchange of domain-specific documents-such as laboratory reports, imaging studies, and discharge summaries-aligned with recognized content profiles (e.g., XDS-MS, XPHR, XDS-I, XD-Lab).
- Interoperable clinical workflows: Promotes streamlined information workflows and reduces data fragmentation across systems, enhancing continuity of care and supporting data-driven healthcare initiatives.
Related Standards
ISO/TS 27790:2026 is designed to work in conjunction with a range of related international standards and integration profiles, including:
- IHE IT Infrastructure profiles: Cross-Enterprise Document Sharing (XDS.b), Audit Trail and Node Authentication (ATNA), Consistent Time (CT), Patient Identification Cross-Referencing (PIX), Patient Demographics Query (PDQ), Basic Patient Privacy Consent (BPPC), Cross-Enterprise User Assertion (XUA)
- IHE Mobile profiles: Mobile access to Health Documents (MHD), Mobile Health Document Sharing (MHDS)
- HL7 standards: HL7 FHIR (Fast Healthcare Interoperability Resources), HL7 CDA (Clinical Document Architecture)
- Content integration profiles: XDS-MS (Cross-enterprise sharing of medical summaries), XPHR (Exchange of Personal Health Records), XDS-I (Radiology), XD-Lab (Laboratory)
- Other standards: DICOM for medical imaging, ISO 7498-2 (Security Architecture), and ISO 13606 (Electronic health record communication)
By leveraging and harmonizing these global standards, ISO/TS 27790:2026 forms a flexible, secure, and scalable foundation for modern health information exchange, facilitating improved healthcare delivery and supporting the evolving needs of digital health ecosystems.
