Health informatics - Patient healthcard data - Part 2: Common objects (ISO 21549-2:2014)

EN ISO 21549-2 establishes a common framework for the content and the structure of common objects used to construct or referenced by other data objects data held on patient healthcare data cards. This part of ISO 21549 is applicable to situations in which such data is recorded on or transported by patient healthcards compliant with the physical dimensions of ID-1 cards defined by ISO/IEC 7810. This part of ISO 21549 specifies the basic structure of the data, but does not specify or mandate particular data-sets for storage on devices. The detailed functions and mechanisms of the following services are not within the scope of this part of ISO 21549, (although its structures can accommodate suitable data objects elsewhere specified): - the encoding of free text data; - security functions and related services which are likely to be specified by users for data cards depending on their specific application, for example: confidentiality protection, data integrity protection, and authentication of persons and devices related to these functions; - access control services which may depend on active use of some data card classes such as microprocessor cards; - the initialization and issuing process (which begins the operating lifetime of an individual data card, and by which the data card is prepared for the data to be subsequently communicated to it according to this part of ISO 21549). The following topics are therefore beyond the scope of this part of ISO 21549: - physical or logical solutions for the practical functioning of particular types of data cards; - how the message is processed further ‘downstream’ of the interface between two systems; - the form which data takes for use outside the data card, or the way in which such data is visibly represented on the data card or elsewhere.

Zdravstvena informatika - Podatki o pacientu na zdravstveni kartici - 2. del: Skupni elementi (ISO 21549-2:2014)

EN ISO 21549-2 uvaja skupni okvir za vsebino in strukturo običajnih predmetov, ki se uporabljajo za konstrukcijo ali ki jih navajajo drugi podatkovni predmeti na zdravstveni kartici pacienta. Ta del standarda ISO 21549 se uporablja za situacije, kjer se takšni podatki zapišejo na zdravstvene kartice pacientov, skladne s fizičnimi merami kartic ID-1, kot jih določa ISO/IEC 7810, oziroma se podatki prenašajo na tak način. Ta del standarda ISO 21549 navaja osnovne strukture podatkov, vendar ne navaja ali določa specifičnih naborov podatkov za shranjevanje v napravah. Podrobno delovanje in mehanizmi naslednjih storitev niso del obsega tega dela standarda ISO 21549 (čeprav njihove strukture omogočajo prilagajanje primernih podatkovnih predmetov, navedenih drugje): – kodiranje podatkov prostega besedila; – varnostne funkcije in povezane storitve, za katere obstaja verjetnost, da jih bodo uporabniki navedli za podatkovne kartice, glede na specifično uporabo, npr.: varovanje zaupnosti, varovanje integritete podatkov in preverjanje pristnosti oseb in naprav, povezanih s temi nalogami; – storitve nadzora do dostopa, ki so lahko odvisne od aktivne uporabe nekaterih razredov podatkovnih kartic, kot so mikroprocesorske kartice; – postopek inicializacije in izdaje (s katerim se začne življenjska doba uporabe posamezne podatkovne kartice in s katerim se podatkovna kartica pripravi za podatke, ki ji bodo posledično sporočene v skladu s tem delom standarda ISO 21549). Naslednje teme ne spadajo na področje uporabe tega dela standarda ISO 21549: – fizične in logične storitve za praktično delovanje določenih vrst podatkovnih kartic; – način nadaljnje obdelave sporočila pod vmesnikom med dvema sistemoma; – oblika, v kateri so podatki za uporabo zunaj podatkovne kartice, ali način, kako so ti podatki vidno predstavljeni na podatkovni kartici ali drugje.

Introduction
This part of ISO 21549 provides data structures and definitions for limited clinical data for use within
patient-held healthcare data cards.
With a more mobile population, greater healthcare delivery in the community and at patients’ homes,
together with a growing demand for improved quality of ambulatory care, portable information
systems and stores have increasingly been developed and used. Such devices are used for tasks ranging
from identification, through portable medical record files, and on to patient-transportable monitoring
systems.
The functions of such devices are to carry and to transmit person-identifiable information between
themselves and other systems; therefore, during their operational lifetime they may share information
with many technologically different systems which differ greatly in their functions and capabilities.
Healthcare administration increasingly relies upon similar automated identification systems. For
instance prescriptions may be automated and data exchange carried out at a number of sites using
patient transportable computer readable devices. Healthcare insurers and providers are increasingly
involved in cross-region care, where reimbursement may require automated data exchange between
dissimilar healthcare systems.
The advent of remotely accessible data bases and support systems has led to the development and use of
“Healthcare Person” identification devices that are also able to perform security functions and transmit
digital signatures to remote systems via networks.
With the growing use of data cards for practical everyday healthcare delivery, the need has arisen for a
standardized data format for interchange.
The person-related data carried by a data card can be categorized in three broad types: identification
(of the device itself and the individual to whom the data it carries relates), administrative and clinical.
It is important to realize that a given healthcare data card “de facto” has to contain device data and
identification data and may in addition contain administrative, clinical, prescription and linkage data.
Device data is defined to include:
— identification of the device itself;
— identification of the functions and functioning capabilities of the device.
Identification data may include:
— unique identification of the device holder or of all other persons to whom the data carried by the
device are related.
Administrative data may include:
— complementary person(s)-related data;
— identification of the funding of healthcare, whether public or private, and their relationships i.e.
insurer(s), contract(s) and policy(ies) or types of benefits;
— other data (distinguishable from clinical data) that are necessary for the purpose of healthcare
delivery.
Clinical data may include:
— items that provide information about health and health events;
— their appraisal and labeling by a healthcare provider (HCP);
— related actions planned requested or performed.

ISO 21549-2:2014(E)

Because a data card essentially provides specific answers to definite queries while having at the same
time a need to optimize the use of memory by avoiding redundancies, “high level” Object Modeling
Technique (OMT) has been applied with respect to the definition of healthcare data card data structures.
Data in the four categories above share many features. For instance, each may need to include ID
numbers, names and dates. Some information may also have clinical as well as administrative uses.
Therefore it has been considered inadequate to provide a simple list of items carried by healthcare data
cards without applying a generic organization, based upon the existence of basic data elements. These
may be defined by their characteristics (e.g. their format), and from them compound data objects may
be constructed; several such objects may also share attributes.
This part of ISO 21549 describes and defines the Common Data objects used within or referenced by
patient held health data cards using UML, plain text and Abstract Syntax Notation (ASN.1).
These data objects are utilized in all forms of healthcare data cards and are used to construct compound
data objects as defined in Parts 3 to 8 of ISO 21549.

Health informatics — Patient healthcard data —
Part 2:
Common objects
1 Scope
This part of ISO 21549 establishes a common framework for the content and the structure of common
objects used to construct data held on patient healthcare data cards. It is also applicable to common
objects referenced by other data objects.
This part of ISO 21549 is applicable to situations in which such data is recorded on or transported by
patient healthcards compliant with the physical dimensions of ID-1 cards defined by ISO/IEC 7810.
This part of ISO 21549 specifies the basic structure of the data, but does not specify or mandate particular
data-sets for storage on devices.
The detailed functions and mechanisms of the following services are not within the scope of this part of
ISO 21549, (although its structures can accommodate suitable data objects elsewhere specified):
— the encoding of free text data;
— security functions and related services which are likely to be specified by users for data cards
depending on their specific application, for example: confidentiality protection, data integrity
protection, and authentication of persons and devices related to these functions;
— access control services which may depend on active use of some data card classes such as
microprocessor cards;
— the initialization and issuing process (which begins the operating lifetime of an individual data
card, and by which the data card is prepared for the data to be subsequently communicated to it
according to this part of ISO 21549).
The following topics are therefore beyond the scope of this part of ISO 21549:
— physical or logical solutions for the practical functioning of particular types of data cards;
— how the message is processed further ‘downstream’ of the interface between two systems;
— the form which data takes for use outside the data card, or the way in which such data is visibly
represented on the data card or elsewhere.

5 Basic data object model for a healthcare data card - Patient healthcard data
object structure
A set of basic data objects have been designed to facilitate the storage of clinical data in a flexible structure,
allowing for future application specific enhancements. These tools should help the implementation
of common accessory characteristics of stored data in a way that allows efficient use of memory, an
important feature for many types of data cards.
The tools consist of a generic data structure based on an object-oriented model represented as an UML
class diagram as shown in Figure 1.

Figure 1 — Patient healthcard data: overall structure
The content of this object-oriented structure is described below and intrinsically will also require the
use of data objects not defined within this part of ISO 21549.
NOTE 1 This part of ISO 21549 is purely applicable to patient healthcards containing health data. Data objects
containing financial and healthcare reimbursement data are not defined within this International Standard.
NOTE 2 It is possible to take the data objects and recombine them while preserving their context-specific tags,
and to define new objects, while still preserving interoperability.
In addition to the capability of building complex aggregate data objects from simpler building blocks,
this part of ISO 21549 allows for associations between certain objects so that information can be shared.
This feature is mainly used to allow, for example, a set of accessory attributes to be used as services to
several stored information objects.
6 Basic data objects for referencing
6.1 Overview
A series of generally useful data type definitions have been made that have no intrinsic value in
themselves, but which are used to define other objects within this multi-part standard. Operations may
be performed with these objects in association with other information objects to “add value”.

6.2 Internal links
6.2.1 General
A number of objects in the data model of this part of ISO 21549 are used mainly as a reference to other
objects. In many situations constructed objects contain a general pointer called a RefPointer that is a
sequence of tags allowing a reference to any object, including sub-objects that can only be referenced as
part of a constructed object, using an application-specific tag and a number of context-specific tags to
sufficient depth.
6.2.2 The “ReferencePointer” and “ReferenceTag” data objects
A general reference pointer is defined in this part of ISO 21549 as an ordered list of tags pointing to
the object or sub-object that is referenced. The data object “RefPointer” shall consist of a sequence of
“RefTag” (of integer type). The “RefTag” is the application-specific tag of the object as defined in this part
of ISO 21549. Each following “RefTag” in Table 1 specifies the context-specific tag in increasing depth.
Table 1 — The specification of individual entities within the object RefPointer
Object name Data Multiplicity Comments
Type
RefTag Integer 1.* This is a sequence of references to other objects. The Refer-
ence is the ASN.1 Tag of another data object.
6.3 Coded data
6.3.1 General
Coded values are understood by reference to the coding scheme to which they apply. The general
principle in this part of ISO 21549 is that it is not mandatory to use a particular coding scheme, unless
specified within this part of ISO 21549, when such codes act as parameters. One example is the use of
ISO 3166-1 for country codes.
When a coding scheme is exclusively specified within this part of ISO 21549 no alternative coding
scheme shall be allowed. Any references to coding schemes not so specified may however be modified in
the future independent of the rest of this part of ISO 21549.
6.3.2 The data object CodingSchemesUsed
A coding scheme in accordance with ISO 21090 shall be referred to by a unique identifier, which allows
unambiguous reference to standard code systems and other local code systems. Where either ISO or HL7
have assigned the unique identifiers to coding schemes, then these identifiers shall be used. Otherwise
implementations shall use an appropriate ISO Object Identifier (OID) or UUID to construct a globally
unique local coding scheme identifier.
The data object CodingSchemesUsed shall consist of an ordered sequence of the sub-object CodingScheme,
which shall itself consist of a code identifier, a code length (of integer type), and an optional free text
comment (an octet string with a length of between 1 and 20 characters). Figure 2 and Table 2 define
CodingScheme data object.

The object codingSchemeRef is a RefPointer pointing at a value that identifies a particular coding scheme
within the object coding schemes used. If codingSchemeRef = 0 then the coding scheme is implicit in this
part of ISO 21549.
The object codeDataValue has been defined to indicate the actual code value in a particular coding
scheme. Figure 3 and Table 3 define CodedData data object.
