Zdravstvena informatika - Podatki o pacientu na zdravstveni kartici - 4. del: Razširjeni klinični podatki (ISO 21549-4:2014)
EN ISO 21549-4 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 mednarodni standard navaja osnovne strukture podatkov, ki so vsebovani v predmetu razširjenih kliničnih podatkov, vendar ne navaja ali določa specifičnih naborov podatkov za shranjevanje v napravah. Za olajšanje interoperabilnosti, ko je aplikacija ustvarjena za uporabo v zdravstveni domeni v skladu s tem mednarodnim standardom, je treba za zadevno aplikacijo uporabiti podatkovne elemente s seznama predmetov (nekateri so razširljivi), ki je naveden v točkah od 6 do 8. Nato je treba te uporabiti skupaj z drugimi podatki, opredeljenimi v drugih delih tega mednarodnega standarda. Podrobno delovanje in mehanizmi naslednjih storitev niso del obsega tega mednarodnega standarda (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 osnutkom mednarodnega standarda). Naslednje teme zato ne spadajo na področje uporabe tega mednarodnega standarda: – 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
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.
The advent of remotely accessible databases 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
standardised data format for interchange.
The person related data carried by a data card can be categorised in three broad types: identification
(of the device itself and the individual to whom the data it caries 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, medication and linkage data.
Device data are 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;
— 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 provider (HCP);
— related actions planned requested or performed.
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 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 Extended Clinical Data objects used within or referenced
by patient held health data cards using UML, plain text and Abstract Syntax Notation (ASN.1).

INTERNATIONAL STANDARD ISO 21549-4:2014(E)
Health informatics — Patient healthcard data —
Part 4:
Extended clinical data
1 Scope
This part of ISO 21549 is applicable to situations in which clinical data additional to the limited clinical
data defined in ISO 21549-3 is recorded on or transported by patient healthcare data cards 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 contained within the data object extended
clinical data, but does not specify or mandate particular data sets for storage on devices.
In order to facilitate interoperability, whenever an application is built for use in the healthcare domain
in compliance with this part of ISO 21549, data items required for that application are drawn from the
list of objects (some of which are extensible) as provided in Clause 5. These are used in conjunction with
other data defined in other parts of this International Standard.
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 initialisation 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 are visibly
represented on the data card or elsewhere.

5.1 Patient HDC 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 below in Figure 1.

Figure 1 — Patient healthcard data: overall structure
The content of this object-oriented structure described in Clause 7 and Annex A will also require the use
of data objects not defined within this part of ISO 21549.
NOTE 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.
5.2 Basic data objects for referencing
5.2.1 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 part of ISO 21549. Operations may be
performed with these objects in association with other information objects to “add value”. These objects
have formal definitions within ISO 21549-2.
5.2.2 Coded data
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 International Standard.
The data object CodedData shall be constructed according to the definition contained in ISO 21549-2.
5.2.3 Device and data security attributes
Data stored in data cards used in health care may be personally sensitive. For this reason this part
of ISO 21549 utilizes a series of security attributes, defined in ISO 21549-2. The actual data content
(value) is not within the scope of this part of ISO 21549, nor are the mechanisms that make use of these
data elements. It is emphasized that the security attributes cannot satisfy given security requirements
without the implementation of the appropriate security functions and mechanisms within the data card.
Such access privileges are attributable to specific individuals with respect to discrete data items. These
privileges will be defined by application developers and can be controlled by automated systems such as
© ISO 2014 – All rights reserved 3
---------------------- Page: 17 ----------------------
SIST EN ISO 21549-4:2014
ISO 21549-4:2014(E)
healthcare professional cards. The privileges may be defined at the application level thereby providing
application and potential country specificity.
The data object SecurityServices provides for the storage of data required to deliver these security
functions and mechanisms. This data can be “attached” to individual data elements thereby preserving
the original author’s security requirements when the data object is transferred between different forms
of data card. This mechanism may therefore ensure that in the process of transferring data from active
to passive media and then back to active media, the original security requirements are regenerated.
This ability also allows exact replication of a data card such as on regeneration after failure.
5.2.4 Accessory attributes
The data object AccessoryAttributes shall consist of an ordered set of data that is essential to record an
audit trail regarding both the originator of the information and the means via which it arrives to the
recipient as defined in ISO 21549-2.
6 Functional requirements on card information for extended clinical data
6.1 Overview of supported uses
The major consideration in this part of ISO 21549 is for HDC:
— to carry the clinical messages (orders, referrals and reports) between the loosely coupled healthcare
parties (i.e. parties that are not able to establish network connections or do not have the third
trusted party yet);
— to carry the links and access keys to clinical messages between the tightly coupled healthcare
parties (i.e. the parties that are able to establish network connection and have the third trusted
party);
— to carry coded summaries of diagnosis and procedures extending limited clinical data set described
in ISO 21549-3. These summaries may be considered as the national or even institutional extensions
of limited clinical data.
6.2 Clinical message transfer between healthcare parties
HDC designed to transfer clinical messages between healthcare parties shall be considered as a secure
data media for a relaying agent. Such HDC may receive clinical messages without a predefined target
healthcare party and may also play a role in authenticating the eligibility of the healthcare party to
retrieve these clinical data.
7 Extended clinical data
7.1 General
The ExtendedClinicalData object is specifically divided into two separate data objects, index of
clinical events (class ClinicalEventDescription), and sequence of mapped clinical messages (class
MappedClinicalMessage). Because of their groupings each of these can have differing security settings
including access rights as determined by the provisions contained within accessory attributes (class
AccessoryAttributes).
Figure 2 and Table 1 define ExtendedClinicalData data object.

contain the optional element AccessoryAttributes. This object is intended to support the process of a
selection of the relevant clinical message.
