Health informatics - Categorial structures for systems of concepts

1.1   Main purpose
The purpose of this European Standard is to establish the characteristics and the conformance rules required to synthetically describe the organisation and content of a terminological system in health. This European Standard has been developed to allow the production of specific standards on categorial structures for particular healthcare subject fields with the minimum requirements to support meaningful exchange of information.
This European Standard is applicable to:
- facilitate the construction of new terminological systems in a regular form which will increase their coherence and expressiveness;
- facilitate maintenance of terminological systems;
- increase consistency and coherence of existing terminological system;
- allow systematic cross-references between items of different types of terminological systems;
- facilitate convergence among terminological systems;
- make explicit the overlap between different health care domains terminological systems;
- provide elements for negotiation about integration of different terminological systems into information systems between the respective developers;
- enable the systematic evaluation of terminological systems.
1.2   Target groups
The target groups for this European Standard are:
- designers of specialised standard healthcare terminological categorial structures;
- developers of healthcare terminological systems including classifications and coding systems;
- producers of services for terminological systems and designers of software including natural language processing;
- information modellers, knowledge engineers, and standards developers building models for health information management systems;
- developers of information systems that require an explicit system of concepts;
- developers of mark-up standards for representation of healthcare documents

Introduction

Computer-based processing and interchange of medical or clinical information require various kinds of

terminological systems of concepts to represent that information, such as controlled vocabularies,

classifications, nomenclatures, terminologies and thesauri, with or without coding schemes.

The specific terminological issues in the field of health informatics are:

- large number of different terminological systems are available in different clinical specialties;

-large overlap among the subject fields involved;

-large number of codes and rubrics, typically in the order of magnitude of 10,000 to 100,000 entries, in

commonly used terminological systems;
- increasing need for re-use of coded data in different health-care contexts;
- polysemy across different clinical specialties and sometimes within them.

The integration of computer-based medical records and administrative information systems in Electronic

Health Records (EHR) requires rationalisation in the field, and a uniform way to represent the meaning of

medical concepts to ensure that the receiver EHR of a message will catch the meaning introduced by the

sender EHR and not only the string of characters embedded in it. It is not possible to impose a rigid uniform

standardised natural language clinical terminology on healthcare providers.

Instead a domain specific semantic model has been envisioned and applied in a series of specific European

standards (EN) and international standards (ISO) on various subject fields to describe a set of categorial

structures in partially overlapping subject fields: a European standard for surgical procedures (EN 1828), an

ISO standard on integration of a reference model for nursing (EN ISO 18104) and an ISO technical

specification on medical devices. There are also several European Pre standards (ENV) for: clinical laboratory

measurements (ENV 1614), medical devices (ENV 12611), vital signs (EN ISO:IEEE 11073-10101 - Part

10101: Nomenclature), point-of-care medical device communication (EN ISO:IEEE 11073-10101 - Part 10101:

Nomenclature), medicinal products (ENV 12610), nursing (ENV 14032) and continuity of care (ENV 13940).

This European Standard specifies the terminology and categorical structure description to be used for

systems of concepts. Field testing in several countries, revision and integration have provided the

comprehensive basis for this document.

and expressiveness;
- facilitate maintenance of terminological systems;
- increase consistency and coherence of existing terminological systems;

- allow systematic cross-references between items of different types of terminological systems;

- provide elements for negotiation about integration of different terminological systems into information

systems between the respective developers;
- enable the systematic evaluation of terminological systems.
1.2 Target groups
The target groups for this European Standard are:

- designers of specialised standard healthcare terminological categorial structures;

- developers of healthcare terminological systems including classifications and coding systems;

- producers of services for terminological systems and designers of software including applications for natural

language processing;

- information modellers, knowledge engineers, and standards developers building models for health

information management systems;
- developers of information systems that require an explicit system of concepts;
- developers of mark-up standards for representation of healthcare documents.
1.3 Topics outside the scope

This European Standard has been developed for use as an integrated part of computer-based applications

and for the electronic healthcare record. It would be of limited value for manual use.

This European Standard itself is not suitable for or intended for use by individual clinicians or hospital

administrators.

It is not the purpose of this European Standard to standardise the end user classification or to conflict with the

concept systems embedded in national practice and languages.

This European Standard is applicable to any healthcare terminology in any healthcare terminological system.

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
concept
unit of knowledge created by a unique combination of characteristics (3.2)

NOTE Concepts are not necessarily bound to particular languages. They are, however, influenced by the social or

cultural background often leading to different categorisations.[ISO 1087-1:2000]
3.2
characteristic
abstraction of a property of an object (3.3) or of a set of objects (3.3)
[ISO 1087-1:2000]

NOTE Characteristics are used for describing concepts (3.1) or of members of a set of objects (3.3) which form

the extension (3.27) of a concept (3.1)
3.3
object
anything perceivable or conceivable

NOTE Objects may be material (e.g. an engine, a sheet of paper, a diamond), immaterial (e.g. conversion ratio, a

project plan) or imagined (e.g. a unicorn).
[ISO 1087-1:2000]
3.4
concept system
system of concepts
set of concepts (3.1) structured according to the relations among them
[ISO 1087-1:2000]
3.5
formal representation

system of symbols which stand for concepts (3.1) and/or the relations between them and which is governed

by explicit rules
3.6
concept representation
formal representation (3.5) of a concept (3.1)

NOTE Informally, we often talk of ’concepts’ when we mean ’concept representations’. However, this leads to

confusion when precise meanings are required. Concepts arise out of human individual and social conceptualisation

---------------------- Page: 8 ----------------------
SIST EN 12264:2005
EN 12264:2005 (E)

of the world around them. Concept representations are artefacts constructed of symbols and often manifest in

computer programs. Because they are artefacts, we can be precise about the functioning and capabilities of concept

representations. It is more difficult to be clear about the yet poorly understood function of human conceptualisation.

3.7
concept system representation
formal representation (3.5) of a system of concepts (3.4)

NOTE Informally, we often talk of ’concept systems’ when we mean ’concept system representations’. However,

this leads to confusion when precise meanings are required. Concepts arise out of human individual and social

conceptualisation of the world around them. Concept system representations are artefacts constructed of symbols

and often manifest in computer programs. Because they are artefacts, we can be precise about the functioning and

capabilities of concept systems representation. It is more difficult to be clear about the yet poorly understood function

of human conceptualisation.
3.8
concept name

term (3.36) which uniquely designates a concept (3.1) within a concept system (3.4)

3.9
concept representation name
(3.36) which uniquely designates a (3.7)
term concept representation
3.10
hierarchical relation
relation between two concepts (3.
