Health informatics - Electronic health record communication - Part 1: Reference model (ISO 13606-1:2008)

ISO 13606-1:2008 specifies the communication of part or all of the electronic health record (EHR) of a single identified subject of care between EHR systems, or between EHR systems and a centralized EHR data repository.
It may also be used for EHR communication between an EHR system or repository and clinical applications or middleware components (such as decision support components) that need to access or provide EHR data, or as the representation of EHR data within a distributed (federated) record system.
ISO 13606-1:2008 will predominantly be used to support the direct care given to identifiable individuals, or to support population monitoring systems such as disease registries and public health surveillance. Use of health records for other purposes such as teaching, clinical audit, administration and reporting, service management, research and epidemiology, which often require anonymization or aggregation of individual records, are not the focus of ISO 13606-1:2008 but such secondary uses might also find this document useful.

Informatique de santé - Communication du dossier de santé informatisé - Partie 1: Modèle de référence (ISO 13606-1:2008)

L'ISO 13606-1:2008 spécifie la communication de tout ou partie du dossier informatisé de santé (DIS) d'un seul sujet de soins identifié entre systèmes de DIS, ou entre des systèmes de DIS et un réceptacle de données de DIS centralisé.
Elle peut également être utilisée pour la communication de DIS entre un système ou réceptacle de DIS et des applications médicales ou composants intergiciels (tels que des composants d'aide à la prise de décision) nécessitant d'avoir d'accès aux ou de fournir des données DIS dans un système réparti (fédéré).
L'ISO 13606-1:2008 est destinée à être principalement utilisée pour prendre en charge les soins directs dispensés à des personnes identifiables, ou les systèmes d'observation de la population tels que les registres de maladies et l'observation de la santé publique. L'utilisation des dossiers de santé pour d'autres finalités telles que l'enseignement, l'évaluation médicale, l'administration et l'établissement de rapports, la gestion des services de santé, la recherche et l'épidémiologie, qui nécessitent l'agrégation de dossiers individuels de personnes physiques ne constitue pas l'objet de l'ISO 13606-1:2008; néanmoins, ces applications secondaires sont susceptibles de trouver un intérêt à cette norme.

Zdravstvena informatika - Komunikacija z elektronskimi zapisi na področju zdravstva - 1. del: Referenčni model (ISO 13606-1:2008)

Ta del standarda ISO 13606 določa komunikacijo dela ali vseh elektronskih zdravstvenih kartonov (EHR) identificiranega predmeta med sistemi EHR oziroma med sistemi EHR in centralizirano bazo podatkov EHR. Lahko se uporablja tudi za komunikacijo med sistemom EHR, aplikacijami za shranjevanje in kliničnimi aplikacijami oziroma komponentami vmesne programske opreme (kot so podporne komponente odločanja), ki potrebujejo dostop do podatkov EHR ali zagotavljajo podatke EHR, ali za predstavitev podatkov EHR v okviru porazdeljenega (združenega) sistema evidentiranja. Ta del standarda ISO 13606 se uporablja predvsem za podpiranje neposredne nege za prepoznavne posameznike ali za podpiranje sistemov nadzorovanja prebivalstva, kot so arhivi bolezni in nadzor javnega zdravja. Uporaba zdravstvenih arhivov za druge namene, kot so učenje, klinična presoja, upravljanje in poročanje, upravljanje storitev, raziskave in epidemiologija, ki pogosto zahtevajo anonimizacijo ali združevanje posameznih arhivov, niso osrednji predmet tega dela standarda ISO 13606, vendar je ta dokument lahko uporaben tudi za tovrstno sekundarno uporabo. Ta del večdelne serije, ISO 13606, je specifikacija z informacijskega vidika, kot je opredeljeno v standardu ISO/IEC 10746-1. Namen tega dela standarda ISO 13606 ni določitev notranje arhitekture ali oblikovanja podatkovne zbirke sistemov EHR.

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 13606-1 was prepared by Technical Committee ISO/TC 215, Health informatics.

ISO 13606 consists of the following parts, under the general title Health informatics — Electronic health record

communication:
⎯ Part 1: Reference model
⎯ Part 2: Archetype interchange specification
⎯ Part 3: Reference archetypes and term lists

0 Introduction
0.1 Preface

The overall goal of ISO 13606 is to define a rigorous and stable information architecture for communicating

part or all of the Electronic Health Record (EHR) of a single subject of care (patient). This is to support the

interoperability of systems and components that need to communicate (access, transfer, add or modify) EHR

data via electronic messages or as distributed objects:
⎯ preserving the original clinical meaning intended by the author;

⎯ reflecting the confidentiality of that data as intended by the author and patient.

ISO 13606 is not intended to specify the internal architecture or database design of EHR systems or

components. Nor is it intended to prescribe the kinds of clinical application that might require or contribute

EHR data in particular settings, domains or specialities. For this reason, the information model proposed here

is called the EHR Extract, and might be used to define a message, an XML document or schema, or an object

interface. The information model in this part of ISO 13606 is an ISO Reference Model for Open Distributed

Processing (RM-ODP) RM-ODP Information Viewpoint of the EHR Extract.

ISO 13606 considers the EHR to be the persistent longitudinal and potentially multi-enterprise or multi-

national record of health and care provision relating to a single subject of care (the patient), created and

stored in one or more physical systems in order to inform the subject’s future healthcare and to provide a

medico-legal record of care that has been provided. Whilst an EHR service or system will need to interact with

many other services or systems providing terminology, medical knowledge, guidelines, workflow, security,

persons registries, billing etc., ISO 13606 has only touched on those areas if some persistent trace of such

interactions is required in the EHR itself, and requires specific features in the reference model to allow their

communication.

ISO 13606 may offer a practical and useful contribution to the design of EHR systems but will primarily be

realised as a common set of external interfaces or messages built on otherwise heterogeneous clinical

systems.

This part of ISO 13606 is the first part to be published of a five-part series. In this part of ISO 13606

dependency upon one of the other parts of this series is explicitly stated where it applies.

0.2 Technical approach

ISO 13606 has drawn on the practical experience that has been gained in implementing a European precursor

prestandard, ENV 13606, other EHR-related standards and specifications, commercial systems and

demonstrator pilots in the communication of whole or part of patients’ EHRs, and on fifteen years of research

findings in the field. ISO 13606 builds on ENV 13606, in order to provide a more rigorous and complete

specification, to accommodate new requirements identified, to incorporate a robust means of applying the

generic models to individual clinical domains, and to enable communication using HL7 version 3 messages. A

mapping from the European prestandard is also provided to support implementers of systems that conformed

to it. The technical approach to producing ISO 13606 has taken into account several contemporary areas of

requirement.

a) In addition to a traditional message-based communication between isolated clinical systems, the

Electronic Health Record will in some cases be implemented as a middleware component (a record

server) using distributed object technology and/or web services.

SIST EN ISO 13606-1:2012
ISO 13606-1:2008(E)

b) “Customers” of such record services will be not only other electronic health record systems but also other

middleware services such as security components, workflow systems, alerting and decision support

services and other medical knowledge agents.

c) There is wide international interest in this work, and this part of ISO 13606 has been drafted jointly

through CEN and ISO with significant input from many member countries.

d) Mapping to HL7 version 3 has been considered an important goal, to enable conformance to this part of

ISO 13606 within an HL7 version 3 environment.

e) The research and development (R & D) inputs on which ENV 13606 was based have moved forward

since 1999 and important new contributions to the field have been taken into account. The open EHR

foundation, integrating threads of R & D in Europe and Australia, is one such example.

Given the diversity of deployed EHR systems, ISO 13606 has made most features of EHR communication

optional rather than mandatory. However, some degree of prescription is required to make EHR Extracts

safely processable by an EHR recipient system, which is reflected through mandatory properties within the

models in Parts 1, 2, and 4, and through normative term lists (defined in Part 3).

ISO 13606 will, in practice, usually be adopted alongside other health informatics standards that define

particular aspects of health data representation. Annex B explains how ISO 13606 can be used alongside key

complementary standards, including the HL7 Version 3 Reference Information Model (RIM), EN 14822-1, EN

14822-2, EN 14822-3, CEN/TS 14822-4 (GPIC), prEN 12967 (HISA) and prEN13940 (CONTSYS).

0.3 The Dual Model approach

The challenge for EHR interoperability is to devise a generalized approach to representing every conceivable

kind of health record data structure in a consistent way. This needs to cater for records arising from any

profession, speciality or service, whilst recognising that the clinical data sets, value sets, templates, etc.

required by different healthcare domains will be diverse, complex and will change frequently as clinical

practice and medical knowledge advance. This requirement is part of the widely acknowledged health

informatics challenge of semantic interoperability.

The approach adopted by ISO 13606 distinguishes a reference model, defined in this part of ISO 13606 and

used to represent the generic properties of health record information, and archetypes (conforming to an

archetype model, defined in Part 2), which are meta-data used to define patterns for the specific

characteristics of the clinical data that represent the requirements of each particular profession, speciality or

service.

The Reference Model represents the global characteristics of health record components, how they are

aggregated, and the context information required to meet ethical, legal and provenance requirements. This

model defines the set of classes that form the generic building blocks of the EHR. It reflects the stable

characteristics of an electronic health record, and would be embedded in a distributed (federated) EHR

environment as specific messages or interfaces (as specified in Part 5).

This generic information model needs to be complemented by a formal method of communicating and sharing

the organizational structure of predefined classes of EHR fragment corresponding to sets of record

components made in particular clinical situations. These are effectively precoordinated combinations of

named RECORD_COMPONENT hierarchies that are agreed within a community in order to ensure

interoperability, data consistency and data quality.

An Archetype is the formal definition of prescribed combinations of the building-block classes defined in the

Reference Model for particular clinical domains or organizations. An archetype is a formal expression of a

distinct, domain-level concept, expressed in the form of constraints on data whose instances conform to the

reference model. For an EHR_Extract, as defined in this part of ISO 13606, an archetype instance specifies

(and effectively constrains) a particular hierarchy of RECORD_COMPONENT sub-classes, defining or

constraining their names and other relevant attribute values, optionality and multiplicity at any point in the

hierarchy, the data types and value ranges that ELEMENT data values may take, and other constraints.

SIST EN ISO 13606-1:2012
ISO 13606-1:2008(E)

This part of ISO 13606 recognises that archetypes might be used to support communication between some

EHR systems in the future, or might be used as a knowledge specification by some EHR system external

interfaces when mapping parts of an EHR to an EHR_EXTRACT, or might not be used at all between some

EHR systems. The use of archetypes is therefore supported, but not made mandatory, by this part of

ISO 13606. A specification for communicating archetypes is defined by Part 2.
0.4 Requirements basis for this part of ISO 13606

From the early 1990s it was recognised that a generic representation is required for the communication of

arbitrary health record information between systems, and in Europe this has resulted in a succession of EU

sponsored R & D projects and two generations of CEN health informatics standards prior to this International

Standard. These projects and standards have sought to define the generic characteristics of EHR information

and to embody these in information models and message models that could provide a standard interface

between clinical systems. The vision of such work has been to enable diverse and specialist clinical systems

to exchange whole or parts of a person’s EHR in a standardized way that can rigorously and generically

represent the data values and contextual organization of the information in any originating system. A

complementary goal has been to accommodate the evolving nature of medical knowledge and the inherent

diversity of clinical practice.

Many investigations of user and enterprise requirements for the EHR have taken place over this period, which

have sought to span the information needs of diverse specialties across primary, secondary and tertiary care,

between professions and across countries. These requirements have been distilled and analysed by expert

groups, mainly within Europe, in order to identify the basic information that needs to be accommodated within

an EHR information architecture to:

⎯ capture faithfully the original meaning intended by the author of a record entry or set of entries;

⎯ provide a framework appropriate to the needs of professionals and enterprises to analyse and interpret

EHRs on an individual or population basis;

⎯ incorporate the necessary medico-legal constructs to support the safe and relevant communication of

EHR entries between professionals working on the same or different sites.
[41, 48, 57] [36-38] [42, 43]
This work includes the GEHR , EHCR-SupA , Synapses , I4C and Nora projects and

work by the Swedish Institute for Health Services Development (SPRI). These key requirement publications

are listed in the Bibliography [51]. These requirements have recently been consolidated on the international

[9]
stage within an ISO Technical Specification, ISO/TS 18308 .

In this reference model the key EHR contextual requirements for such faithfulness are related to a set of

logical building block classes, with suitable attributes proposed for each level in the EHR extract hierarchy.

ISO/TS 18308 has been adopted as the reference set of requirements to underpin the features within this

EHR communications reference model, and a mapping of these requirements statements to the constructs in

the reference model is given in Annex D.
0.5 Overview of the EHR extract record hierarchy

The information in a health record is inherently hierarchical. Clinical observations, reasoning and intentions

can have a simple or a more complex structure. They are generally organized under headings, and contained

in “documents” such as consultation notes, letters and reports. These documents are usually filed in folders,

and a patient may have more than one folder within a healthcare enterprise (e.g. medical, nursing, obstetric).

The EHR extract reference model needs to reflect this hierarchical structure and organization, meeting

published requirements in order to be faithful to the original clinical context and to ensure meaning is

preserved when records are communicated between heterogeneous clinical systems. To do this, the model

formally sub-divides the EHR hierarchy into parts that have been found to provide a consistent mapping to the

ways which individual EHRs are organized within heterogeneous EHR systems.

0.6 Description of the main Reference Model classes
EHR_EXTRACT

The EHR_EXTRACT is used to represent part or all of the health record information extracted from an EHR

provider system for the purposes of communication to an EHR recipient (which might be another EHR system,

a clinical data repository, a client application or a middleware service such as an electronic guideline

component) and supporting the faithful inclusion of the communicated data in the receiving system.

The EHR_EXTRACT class contains attributes to identify the subject of care whose record this is, the EHR

Provider system from which it has been derived and the identifier of that subject’s EHR in that system, and

optionally the agent responsible for creating it.
The EHR_EXTRACT contains the EHR data, in three parts:
1) a set of COMPOSITIONs;

2) optionally, a directory of FOLDERs that provide a high-level grouping and organizing of the

COMPOSITIONs;

3) optionally, a set of demographic descriptors for each of the persons, organizations, devices or software

components that are identified within (1) and (2) above. This approach allows such entities to be

referenced uniquely via an identifier within the body of the EHR, without repetition of the descriptive

details each time, and also ensures that any EHR_EXTRACT can be interpreted in isolation if the

recipient system does not have access to the services needed to decode the entity identifiers used by the

EHR Provider.

A formal mechanism is defined in Part 4 of ISO 13606 for including access policy information within the

EHR_EXTRACT. This is intended to inform the EHR recipient about the wishes of the subject of care and of
