Overview
ISO 5477:2023 - Health informatics - Interoperability of public health emergency preparedness and response information systems - provides business rules and an informative framework to improve semantic and organizational interoperability of Public Health Emergency Preparedness and Response (PH EPR) information systems. The standard defines the PH EPR domain, outlines data and information management (DIM) processes, and maps existing semantic interoperability standards to PH EPR systems. It is aimed at strengthening preparedness for infectious disease outbreaks, environmental disasters, chemical/nuclear incidents and other public health emergencies.
Key topics and technical requirements
- Domain definition and scope: Clear description of the PH EPR information system domain to support consistent system design and integration.
- Management and conformance principles: Guidance on aligning information systems with incident management principles and organizational interoperability (unity of command).
- Data and information management (DIM): Business rules for establishing strategies, goals, reporting, analytics, visualization, and measure-driven capabilities.
- Data governance: Requirements for availability, usability, integrity, security, ongoing training, and compliance.
- Essential Elements of Information (EEIs) and Critical Information Requirements (CIRs): Processes for defining high-priority information that triggers action.
- Standardized case definitions and terminology: Processes for collecting, developing, maintaining, and applying PH EPR vocabulary, code sets and case definitions (including use of classifications such as ICD where applicable).
- Interoperability characteristics: Semantic and organizational interoperability, expandability without loss of interoperability, usability, adaptability, and support for a common operating picture (COP).
- Vocabulary lifecycle: Stakeholder roles, quality assurance, scalability, maintenance, training and regulatory compliance for PH EPR vocabularies.
- Competencies: Annexes describe knowledge, skills and abilities for emergency operations and informatics professionals.
Applications and who uses it
ISO 5477 is intended for:
- Policy makers and regulators designing national or organizational PH EPR strategies.
- Project planners and system managers implementing interoperable EPR information systems.
- Public health informaticians and data analysts mapping semantic standards, building EEIs/CIRs, and operationalizing case definitions.
- Incident managers, emergency operations centers (EOC), educators, standards developers and academia seeking consistent interoperability and data governance practices.
Practical uses include building interoperable dashboards and COPs, aligning incident management systems with PH data flows, standardizing case reporting across jurisdictions, and defining governance and training for PH EPR data vocabularies.
Related standards
ISO 5477 references and aligns with existing frameworks such as the WHO Framework for Public Health Emergency Operations Centres and ISO family standards (e.g., ISO/IEC 25012, ISO 22320). Implementers should consider these related documents when designing interoperable PH EPR solutions.
