Foreword
This draft European Prestandard has been prepared by Working group 2 "Terminology and knowledge bases" of
CEN/TC 251 "Health Informatics", the secretariat of which is held by SIS. It is a continuation by a voluntary task
force of the work initiated as a Short Strategic Study entitled "Systems of concepts for nursing: a strategy for
progress" produced under mandate M/255 given to CEN by the European Commission and the European Free
Trade Association, order voucher BC/CEN/97/23.6.
All Annexes are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this European Prestandard: Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
Introduction
Terminology models and categorial structures deal with the essential structure for concept systems.
This Prestandard aims at facilitating the process of harmonisation across terminological systems on nursing
diagnoses and nursing actions, by reducing unnecessary diversity and making explicit motivated diversity. It also
aims at assisting integration of terminology systems within health records and other healthcare applications, and
at establishing a continuum between information models and terminology models. Moreover, developers of
terminology systems may use this standard for systematic presentation (i.e. to build taxonomies), to reduce
ambiguities in the expressions, to produce more systematic descriptions.
Robust categorial structures can only be obtained by performing mapping from the various existing systems (and
from real charts), putting them into a database or a description-logic system, and studying deeply the problems
arising from these mappings. To perform this activity on a large scale, a consolidated hypothesis is needed.
The presence of the ENV allows experiments and validations to be concentrated on a precise hypothesis, so
that contributions will be focussed and the evolution towards the final normative content will be effective.
The textual description of the Prestandard is accompanied by a set of tables providing synopses of categorial
structures for the focus of nursing diagnoses (see Subclause 4.2), for nursing diagnoses (see Subclause 4.3),
and for nursing actions (see Subclause 5.2). It should be noted that any examples given in the Prestandard are
non-exhaustive. Graphical outlines (according to the UML conventions, see Subclause 3.2 and Annex D) of the
system of concepts for nursing diagnoses and nursing actions are provided in figures 1 and 2.
The normative part is complemented by 4 informative Annexes.
Annex A provides informal descriptions of the domains and categories in the Prestandard. These are informative
content, intended to clarify the meaning and scope of each item through the use of descriptions and non-
exhaustive examples – they are not normative definitions.
Annex B lists examples of dissections on nursing diagnoses and Annex C on nursing actions.
Annex D provides a synthesis of the UML conventions.

1. SCOPE
1.1 Main purposes
This European Prestandard describes a system of concepts to support the development, maintenance,
comparison and implementation of terminology systems, which in turn support data classification,
communication, storage and retrieval in Nursing Information Systems and Nursing Records. This European
Prestandard includes a set of categorial structures that cover nursing diagnoses and nursing actions.
Even though the Prestandard is centered on nursing needs, it may be used for domains with similar semantic
properties, such as the subject field covered by ICIDH-2.
The main uses foreseen for the system of concepts are to:
- provide a language to highlight the structure and/or the taxonomy of a terminology system, i.e. the most
relevant and systematic criteria used by developers to organise the terminology system. This description
may be used to harmonise a terminology system within the environment of an information system, e.g. by
comparing information models and terminology models.
- provide the criteria to generate systematic names from rubrics and terms of a terminology system, as a
supporting feature to be distributed in the near future together with the usual presentation of the terminology
system itself.
The provisions of this European Prestandard apply to the complete, contextualised meaning of the terms and will
not apply directly to the surface/literal expressions of preferred terms or working terms registered in existing
terminology systems. Often, relevant details pertaining to a term can only be understood from its context within
the terminology system. Therefore, it is recommended that terms be paraphrased to reflect contextualised
meaning before applying this European Prestandard.
Definitions or free text descriptions of these terms contain many pragmatic or assertional concepts (e.g. defining
characteristics of nursing diagnoses) that are outside the scope of the present system of concepts.
The content of this European Prestandard is not intended to be used as a terminology system for end-users.
Systematic representation according to this Prestandard is not intended to replace the original rubric or the
original expression from the coding system or terminology to which it is applied.
Actual descriptors — together with the style and the symbols for the systematic representation — are outside the
scope of this standard. They will be defined by the organisations producing the representations. After trial
implementations of this Prestandard, a harmonised set of descriptors could be considered for inclusion in a
future revision of this Prestandard.
The scope of this Prestandard is limited to the unambiguous representation of the terminological entries. Similar
concepts may have different valid representations according to this Prestandard. It is out of the scope of this
Prestandard to provide normalisation rules to compare two representations and to establish their equivalence.
It is outside the scope of this Prestandard, to define provisions about the nature and content of the guidelines for
the management of status qualifiers (see Subclauses 4.4 and 5.3).

SIST ENV 14032:2003
ENV 14032:2001 (E)
Categorial structures can be used to support different ways of implementing a terminology system. For example:
1. pre-coordinated terms. One data field in an information system contains a term or term phrase that may
represent a systematic combination of concepts. Often this term or term phrase has a predefined non-
combinatorial code, e.g. (from NIC) 6408 “Abuse protection support: religious”.
2. post-coordinated terms. One field in an information system contains a combination of terms (or codes),
created by the user according to predefined rules, e.g. the user’s expression: “moderate restriction in
participation in parent-child relationships” may be represented in ICIDH-2 by the following two terms:
“participation in parent-child relationships” + “moderate restriction”
3. name-value pairs. An entry in an information system may be made up of two fields: one field for a term
or term phrase to represent the variable that is observed and one field for the corresponding value. The
value can be a numeric value, a score, a qualitative scale, a binary value, a coded value.
4. data sets made of a predefined list of names for the variables to be observed, e.g. assessment
templates. At instantiation, the user assigns a value to each variable.
Each of the various categories and qualifiers described in this Prestandard may therefore appear either as part
of a pre-coordinated term, as part of one of the multiple post-coordinated terms, as part of the names of the
variables, or as part of the values. This Prestandard is not precluding any of these solutions or recommending
one particular subdivision, except the ones on status qualifiers described in Subclauses 4.4 and 5.3.
The provisions of this European Prestandard partially apply to classes used to structure terminologies (e.g.
“Heart functions” in ICIDH-2). The terms that represent these classes are too generic to be used alone in nursing
records — i.e. to describe in detail the nursing diagnosis or the nursing action — but they obey the same
semantic rules as the more detailed terms.
1.2 Target groups of this European Prestandard
This European Prestandard is for use by
a) developers of coding systems and terminologies on nursing, to assist in the development and
maintenance of a particular system, as well for comparisons among different systems;
b) developers of categorial structures about other systems of concepts, to take into account the relation
with nursing and to be aware of the overlaps among different subject fields;
c) information modellers and knowledge engineers building models for record systems, in particular to
describe the expected content of terminological value domains for particular attributes and data
elements;
d) developers of information systems which need to handle an explicit system of clinical concepts for
internal organization, datawarehouse management and middleware services;
e) developers of software for Natural Language Processing, to facilitate harmonisation of their output with
coding systems and record structures;
f) developers of markup standards for representation of healthcare documents.
1.3 Topics considered outside the scope of this European Prestandard
This European Prestandard is not intended to provide
a) a detailed classification or nomenclature on nursing diagnoses or nursing actions;
b) descriptors and guidelines to represent contextual information for the recording of information within an
electronic healthcare record;
c) an exhaustive list of all the potential details that could appear in expressions of nursing diagnoses and
nursing actions;
d) an exhaustive thesaurus with the complete list of descriptors to be used to describe nursing diagnoses
and nursing actions.

3. DEFINITIONS AND CONVENTIONS USED IN DIAGRAMS
3.1 Definitions
For the purposes of this standard, the following definitions apply:
3.1.1 associate (semantic) category
semantic category standing for a set of associate concepts [ENV 12264]
EXAMPLE: stands for the set of associate concepts following the semantic link “has means”
that describe the instruments, equipment or tools used to accomplish a nursing action.
3.1.2 associate concept
concept which follows a semantic link [ENV 12264, modified]
EXAMPLE: "patient", following the semantic link “has beneficiary” in a system of concepts on nursing
action.
3.1.3 associate (semantic) domain
semantic domain standing for a set of associate categories
EXAMPLE: in this Prestandard, the semantic link “is applied to” defines an associate domain (called the
<>) including associate categories such as , .
NOTE: the name of an associate domain often reflects the name of the corresponding semantic link, e.g.
“has means” <>, “has beneficiary” <>.
3.1.4 base (semantic) category
semantic category standing for a set of base concepts [ENV 12264]
EXAMPLE: , which indicates sufficiency for a particular requirement, in a system of
concepts on nursing diagnoses.
3.1.5 base concept
concept used systematically as superordinate concept in dissections of target concepts [ENV 12264, modified]
EXAMPLE: the descriptor "informing" can be used systematically in dissections that describe the target
concepts of nursing actions about provision of information to patients or relatives. All these target
concepts are children of “informing”.

---------------------- Page: 8 ----------------------
SIST ENV 14032:2003
ENV 14032:2001 (E)
3.1.6 base (semantic) domain
semantic domain standing for a set of base categories
EXAMPLE: <>, which represents the set of base categories for a nursing diagnosis, such
as or .
3.1.7 categorial structure
reduced system of concepts to describe the essential organization of the semantic categories in a particular
system of concepts for development, maintenance and application of terminology systems [ENV 12264,
modified]
3.1.8 descriptor
concept considered as elementary for usage in a set of dissections
EXAMPLE: “bathing” is a descriptor belonging to the semantic category
NOTE 1: a descriptor (e.g. “bathing oneself”, see Annex B, example 5) may be considered as
elementary for a set of dissections corresponding to a coding system, but the same concept may be
expressed by multiple descriptors for another coding system, i.e. according to different systematisation
needs.
NOTE 2: a descriptor can appear only in one category, but it can be used in multiple semantic domains.
3.1.9 differentiating criterion
semantic link and an associate category
NOTE: differentiating criteria are used to build taxonomies. If an associate semantic domain is involved
in the creation of a new layer of a taxonomy, the corresponding differentiating criteria may generate
subtrees with different structures. E.g. in a coding system of nursing actions, if a layer of the taxonomy is
built according to the semantic link “has means”, then three independent subtrees may be generated,
i.e. one based on the differentiating criterion “has means”-, one based on the differentiating
criterion “has means”-, and one based on the differentiating criterion “has means”-
. In fact, the three internal categorial structures respectively of , and
may involve a different organisation of the subsequent layers of the respective sub-
taxonomies.
3.1.10 dissection
systematic representation of a phrase according to a predefined categorial structure
3.1.11 qualifier
concept used to further specify another concept
EXAMPLE: the qualifier “risk for” further specifies a nursing diagnosis
NOTE: the names for the semantic categories of qualifiers usually are similar to the corresponding
semantic link (e.g. “has existence qualifier”-, “has evolution qualifier”-, has
success qualifier”-).
3.1.12 (semantic) category
concept chosen to stand for a specified set of subordinate concepts, considered homogeneous [ENV 12264]
EXAMPLES: , , ,
NOTE 1: In examples within this Prestandard, semantic categories are enclosed in angle brackets < >.
NOTE 2: a descriptor can appear only in one category.
3.1.13 (semantic) domain
set of semantic categories taking the same role in a system of concepts
7
---------------------- Page: 9 ----------------------
SIST ENV 14032:2003
ENV 14032:2001 (E)
EXAMPLES: <>, <>, <>
NOTE 1: In examples within this Prestandard, semantic domains are enclosed in double angle brackets
<< >>.
NOTE 2: a semantic category may appear in different semantic domains, e.g. can be a
<>, a <>, a <>. Therefore a descriptor may belong to multiple domains
(but only to one semantic category) and the same descriptor can be present in one dissection with
different roles, i.e. it may correspond to different semantic domains (e.g. a “patient” can be the direct
<> and the final <> for a nursing action).
3.1.14 (semantic) link
unidirectional associative relation from one concept to another [ENV 12264, modified]
EXAMPLE: the semantic link “has-site” could be applied from the concept "pain" to the concept "hip", in
a system of concepts to describe nursing diagnoses.
NOTE: A semantic link may be also used between semantic categories and semantic domains.
3.1.15 system of concepts
structured set of concepts established according to the relations between them [ENV 12264]
NOTE: A system of concepts is wider than a categorial structure. For example it may include categories
and semantic links for status qualifiers (see Subclauses 4.4 and 5.3) and multiple categorial structures
(see Subclauses 4.2 and 4.3).
3.1.16 systematic name
terminological phrase created according to preestablished rules and used as name for a target concept [ENV
12264]
NOTE 1: In common practice, a working name can be used in place of the systematic name. The
working name may be either a term or a simpler terminological phrase.
NOTE 2: systematic names are the bridge between working names (e.g. expressions from
nomenclatures, for humans) and formal representations (e.g. dissections, for computers)
3.1.17 target concept
concept whose designation is intended to be used in applications [ENV 12264]
EXAMPLE: "teach patient about diabetes" could be a target concept for nursing actions in a nursing
record application. The concepts: “monitoring”, “teach relatives” are usually considered incomplete in
that context and therefore cannot be considered adequate as target concepts.
3.2 Conventions used in diagrams
The textual description of the categorial structures in the Prestandard is accompanied by graphical outlines,
drawn according to UML conventions (see Annex D, informative).
The correspondence between the UML constructs for information models and the terminological constructs for a
system of concepts is as follows:
The labeled lines in the figures represent semantic links. Direction is implied by the position of the label.
The labels in the upper compartment of the boxes represent either semantic categories or semantic
domains.
Semantic domains are considered as abstract classes of UML and their labels are italicised in the diagrams.
They are enclosed in double angle brackets << >> throughout the document.

---------------------- Page: 10 ----------------------
SIST ENV 14032:2003
ENV 14032:2001 (E)
Semantic categories are considered as instantiable classes in UML and their labels are in plain font in the
diagrams. They are enclosed in angle brackets < > throughout the document
Qualifiers are considered as the attributes in UML and appear in the middle compartment of the boxes.
The lower compartment of the boxes is not used.

4. SYSTEM OF CONCEPTS FOR NURSING DIAGNOSES
4.1 General
For the purposes of this Prestandard, a nursing diagnosis shall be considered either as a judgement on
something (called focus) or as a judgement on a particular dimension (e.g. ability, knowledge) of something.
The categories , and are a special case of nursing
diagnosis as they may contain both judgement and focus (see Note 1 in Subclause 4.3).
The categorial structure for the focus of a nursing diagnosis is described in Subclause 4.2.
The categorial structure for nursing diagnoses is described in Subclause 4.3.
Additional qualifiers that should be used mainly within patient records — rather than within terminological
expressions of nursing diagnoses — are described in Subclause 4.4.
All categories and domains are informally described in Annex A (informative).
A comprehensive graphical outline of the system of concepts for nursing diagnoses is presented in figure 1.

4.2 Categorial structure for the focus of a nursing diagnosis
The categorial structure for the focus of nursing diagnoses is described in detail in this Subclause and is
summarised in table 1.
Developers of a terminology system on <> of nursing diagnoses shall complement their system with
supporting documentation, showing how each rubric or code can be unambiguously represented according to
the provisions of this Subclause.
Extension of the current categorial structure (i.e. the adoption of new categories and new semantic links) is
allowed. It should be carefully documented and shall not be in conflict with the provisions of this Prestandard, in
particular with exclusions stated in Subclause 4.4.
A comprehensive list of descriptors, divided by semantic category and possibly organised into a taxonomy,
should also be provided. Descriptors that are to be considered as defaults, should be clearly stated in the
supporting documentation provided by the developers of the terminology system.
The <> of a nursing diagnosis may be, for example, a , a , a , or
a . The category of shall be used according to the Prestandard ENV 1614. The categories
, , are special cases - see Note 1, Subclause 4.3.
The <> may refer to a <>. This can be a , an (e.g. a wound)
a , or a part of one of these. The <> may be further qualified e.g. by one or more spatial qualifiers
that express a , as appropriate.
The <> may be qualified by a temporal qualifier on .
NOTE 1. The focus is a crucial component of any expression about diagnoses. In practice, nurses
centre their observations on the focus, in order to make a judgement. Diagnoses are often organised
according to the focus when building user-friendly interfaces, and when structuring assessment
templates. The hierarchy on the focus is often used to organise the presentation of terminology systems
(see for example ICIDH-2).
