Overview
ISO/TS 9321:2024 - Health informatics - General requirements of multi-centre medical data collaborative analysis defines the baseline requirements for building and operating systems that enable collaborative analysis of electronic health record (EHR) data across multiple medical centres. The Technical Specification focuses on secure, privacy-preserving architectures and processes for handling structured data, medical text, medical images and other clinical data in multi-centre research. It aims to support reproducible research, consistent results and regulated data protection while minimizing data movement from local centres.
Key topics and technical requirements
- System architecture & workflow
- Defines a distributed, modular architecture with user, service and resource layers plus system security components.
- Includes initiation and implementation workflows for multi-centre research projects.
- Data isolation & storage
- Original medical data remain within each centre’s internal database; transformed data stored in a Common Data Model (CDM).
- Supports incremental, non-disruptive data imports (ETL) so newly acquired records do not conflict with existing data.
- Data and terminology standardization
- Requires terminology bases and capabilities for local-to-standard mapping to achieve semantic, structural and format consistency across centres.
- Privacy-preserving analysis
- Supports federated learning and secure multi-party computing approaches to derive statistical, meta-analysis and model results without centralizing raw data.
- Network scalability & modularization
- Network framework must permit easy enrolment/withdrawal of centres and decompose functionality into independent logical modules.
- Security & governance
- Emphasizes confidentiality, integrity and key management; aligns with ISO/IEC 27001, ISO 27799 and healthcare-specific data protection best practices.
- Functional layers
- Specifies functional requirements for the user, service and resource layers, plus system security controls and APIs.
Practical applications and target users
ISO/TS 9321:2024 is practical for organizations and professionals involved in multi-centre clinical research and health IT systems:
- Developers & integrators building federated research platforms, CDM pipelines and secure APIs.
- IT maintainers & architects designing distributed network frameworks and modular services.
- Data owners & hospital IT teams implementing data isolation, ETL and terminology mapping to participate in consortia.
- Researchers & clinicians conducting cross-centre cohort studies, model development and collaborative analytics.
- Governance & compliance teams ensuring systems meet privacy, security and interoperability requirements.
Related standards
- ISO 27799 (health information security), ISO/IEC 27001 (information security management)
- ISO 22857 and ISO/TS 14265 (data protection and anonymization classification)
- The Technical Specification includes Annex A (example networks) and Annex B (reference implementations) to aid practical adoption.
