Overview
ISO 1828:2012 - Health informatics - Categorial structure for terminological systems of surgical procedures - defines the minimal categorial structure and domain constraints required to build interoperable terminological systems for surgical procedures. Designed for use in computer-based applications and electronic health records (EHRs), the standard specifies the terminology part (per ISO 1087-1:2000) so that surgical procedure data can be exchanged, compared and analysed across systems, languages and surgical disciplines.
Key topics and technical requirements
- Scope and goal: Specifies minimal characteristics of a categorial structure to support interoperability, comparability and meaningful information exchange for surgical procedures.
- Categories defined: Core entity categories include surgical deed, human anatomy, lesion and interventional equipment (e.g., implants, instruments, agents).
- Representations of relations: Defines authorized semantic links such as hasObject and hasSite to express relationships between categories (for example, “removing” hasObject “polyp” which hasSite “colon”).
- Domain constraints: Rules prescribing valid representations of relations for specializing categories within the surgical domain - ensuring consistent concept modelling across terminologies.
- UML support: Includes a UML diagram to illustrate the categorial structure and relations for implementation.
- Terminology-only focus: Covers only the terminology component of terminological systems (not coding or classification rules), enabling mapping and integration with coding schemes and clinical terminologies.
Applications and practical value
- Enables semantic interoperability of surgical procedure data across EHRs, clinical research databases, registries, billing/reimbursement systems, quality assurance and epidemiological reporting.
- Supports development and maintenance of multipurpose terminological systems for national or international use and tools for natural language processing (NLP), mapping and generation of procedure terms.
- Facilitates international comparisons and data exchange where multiple procedure coding systems coexist (e.g., national procedure lists, SNOMED CT, ICHI implementations).
- Intended for system architects, terminology developers, health informatics professionals, software vendors and standards bodies implementing procedure terminology in electronic health records and clinical applications.
