Overview
ISO/HL7 27932:2009 - Data Exchange Standards - HL7 Clinical Document Architecture, Release 2 - standardizes the content and structure of clinical documents for exchange. It defines how clinical reports, summaries and other healthcare documents are represented so they can be shared reliably between systems while preserving clinical meaning, provenance and context. This standard is used to enable interoperable clinical document exchange across healthcare organizations.
Key Topics
- Document structure and composition - rules for organizing clinical documents into standardized sections and hierarchical components to ensure consistent presentation and processing.
- Metadata and provenance - requirements for document identifiers, authorship, creation time, custody and versioning to support traceability and legal use.
- Semantic interoperability - guidance on encoding clinical meanings using controlled vocabularies, coded entries and standardized templates so receiving systems can interpret content accurately.
- Human- and machine-readability - balancing narrative text for clinicians with structured, machine-processable data elements to support both clinical use and automated processing.
- Conformance and templates - mechanisms for constraining the core model to specific clinical use cases (templates or profiles) and for declaring conformance statements.
- Exchange considerations - recommendations for packaging, transport readiness and integration with health information exchange workflows.
Note: implementations commonly realize these concepts using structured markup (for example, XML-based encodings) and agreed templates, enabling both display and computation.
Applications
- Electronic Health Record (EHR) integration - standardizing discharge summaries, referral letters, progress notes and diagnostic reports for exchange between EHR systems.
- Health Information Exchange (HIE) - enabling cross-organizational sharing of clinical documents for continuity of care and care coordination.
- Clinical messaging and reporting - generating interoperable documents for laboratory, radiology and specialist reports.
- Regulatory and legal documentation - supporting auditability and provenance requirements for clinical records.
- Vendors and integrators - developers of EHRs, document management systems, middleware and HIE platforms use the standard to ensure interoperability.
Who Uses It
- Health IT vendors, systems integrators and software developers
- Hospitals, clinics and ambulatory care providers
- National and regional health agencies, standards bodies and implementers
- Clinical informaticians and interoperability architects
Related Standards
- HL7 family of interoperability standards (same organizational origin)
- National/local CDA implementation guides and template libraries
- Other healthcare interoperability initiatives and profiles that complement clinical-document exchange
