Health informatics — Patient healthcard data — Part 3: Limited clinical data

ISO 21549-3:2004 describes and defines the limited clinical data objects used in or referenced by patient-held health data cards using UML, plain text and abstract syntax notation (ASN.1). It is applicable to situations in which such data are recorded on or transported by patient healthcards whose physical dimensions are compliant with those of ID-1 cards as defined by ISO/IEC 7810. It specifies the basic structure of the data contained within the data object limited clinical data, but does not specify or mandate particular data-sets for storage on devices. In particular, the data contained within the data objects in limited clinical data are intended to aid the delivery of emergency care, but are by themselves neither intended, nor suitable, for the provision of all the information required.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 21549-3 was prepared by Technical Committee ISO/TC 215, Health informatics.
ISO 21549 consists of the following parts, under the general title Health informatics — Patient healthcard data:
 Part 1: General structure
 Part 2: Common objects
 Part 3: Limited clinical data
 Part 4: Extended clinical data
 Part 5: Identification data
 Part 6: Administrative data
 Part 7: Electronic prescription (medication data)
 Part 8: Links
At the time of publication of this part of ISO 21549, some of these parts were in preparation.
This work is being carried out by ISO/TC 215 in collaboration with CEN/TC 251, Medical informatics, under
the Vienna Agreement, with ISO having the lead role. This new series of International Standards is intended to
replace the European Prestandard ENV 12018 ratified by CEN in 1997.

ISO 21549-3:2004(E)
Introduction
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 records, 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 into 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 and clinical 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-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 labelling by a healthcare person (HCP);
 related actions planned, requested or performed.

ISO 21549-3:2004(E)
Because a data card essentially provides specific answers to definite queries, whilst at the same time there is
a need to optimize the use of memory by avoiding redundancies, a “high-level” object-modelling technique
(OMT) has been applied with respect to the definition of healthcare data card data structures.
This part of ISO 21549 describes and defines the limited clinical data objects used in or referenced by patient-
held health data cards using UML, plain text and abstract syntax notation (ASN.1).
It does not describe or define the common objects defined within part 2 of this International Standard, even
though they are referenced and utilized within this document.

INTERNATIONAL STANDARD ISO 21549-3:2004(E)

Health informatics — Patient healthcard data —
Part 3:
Limited clinical data
1 Scope
This part of ISO 21549 describes and defines the limited clinical data objects used in or referenced by patient-
held health data cards using UML, plain text and abstract syntax notation (ASN.1).
It is applicable to situations in which such data are recorded on or transported by patient healthcards whose
physical dimensions are compliant with those of ID-1 cards as defined by ISO/IEC 7810.
This part of ISO 21549 specifies the basic structure of the data contained within the data object limited clinical
data, but does not specify or mandate particular data-sets for storage on devices. In particular, the data
contained within the data objects in limited clinical data are intended to aid the delivery of emergency care, but
are by themselves neither intended, nor suitable, for the provision of all the information required.
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 specified elsewhere):
 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 in accordance with
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 card;
 how the message is processed further “downstream” of the interface between two systems;
 the form which data take for use outside the data card, or the way in which such data are visibly
represented on the data card or elsewhere.
