14、 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

15、 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 elec

16、trotechnical 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

17、 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 iden

18、tifying any or all such patent rights. ISO 13606-2 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 s

19、pecification Part 3: Reference archetypes and term lists Part 5: Interface specification BS ISO 13606-2:2008ISO 13606-2:2008(E) ISO 2008 All rights reserved vIntroduction Comprehensive, multi-enterprise and longitudinal electronic health records will often in practice be achieved through the joining

20、 up of multiple clinical applications, databases (and increasingly devices) that are each tailored to the needs of individual conditions, specialties or enterprises. This requires that Electronic Health Record (EHR) data from diverse systems be capable of being mapped to and from a single comprehens

21、ive representation, which is used to underpin interfaces and messages within a distributed network (federation) of EHR systems and services. This common representation has to be sufficiently generic and rich to represent any conceivable health record data, comprising part or all of an EHR (or a set

22、of EHRs) being communicated. The approach adopted in the ISO 13606 series of International Standards, underpinned by international research on the EHR, has been to define a rigorous and generic Reference Model that is suitable for all kinds of data and data structures within an EHR, and in which all

23、 labelling and context information is an integral part of each construct. An EHR Extract (as defined in ISO 13606-1) will contain all the names, structure and context required for it to be interpreted faithfully on receipt, even if its organization and the nature of the clinical content have not bee

24、n “agreed” in advance. However, the wide-scale sharing of health records, and their meaningful analysis across distributed sites, also requires that a consistent approach be used for the clinical (semantic) data structures that will be communicated via the Reference Model, so that equivalent clinica

25、l information is represented consistently. This is necessary in order for clinical applications and analysis tools to safely process EHR data that have come from heterogeneous sources. Archetypes The challenge for EHR interoperability is therefore to devise a generalized approach to representing eve

26、ry 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 health care domains will be diverse, complex

27、 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 this part of ISO 13606 distinguishes a Reference Model, used to represent the generic

28、 properties of health record information, and Archetypes (conforming to an Archetype Model), which are metadata 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 is s

29、pecified as an Open Distributed Processing (ODP) Information Viewpoint Model, representing the global characteristics of health record components, how they are aggregated, and the context information required to meet ethical, legal and provenance requirements. In the ISO 13606 series of Internationa

30、l Standards, the Reference Model is defined in ISO 13606-1. 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 me

31、ssages or interfaces (as specified in ISO 13606-5). Archetypes are effectively pre-coordinated combinations of named RECORD_COMPONENT hierarchies that are agreed within a community in order to ensure semantic interoperability, data consistency and data quality. For an EHR_Extract, as defined in ISO

32、13606-1, an archetype specifies (and effectively constrains) a particular hierarchy of RECORD_COMPONENT subclasses, 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

33、values may take, and may include other dependency constraints. Archetype BS ISO 13606-2:2008ISO 13606-2:2008(E) vi ISO 2008 All rights reservedinstances themselves conform to a formal model, known as an Archetype Model (which is a constraint model, also specified as an ODP Information Viewpoint Mode

34、l). Although the Archetype Model is stable, individual archetype instances may be revised or succeeded by others as clinical practice evolves. Version control ensures that new revisions do not invalidate data created with previous revisions. Archetypes may be used within EHR systems to govern the EH

35、R data committed to a repository. However, for the purposes of this interoperability standard, no assumption is made about the use of archetypes within the EHR provider system whenever this standard is used for EHR communication. It is assumed that the original EHR data, if not already archetyped, m

36、ay be mapped to a set of archetypes, if desired, when generating the EHR_EXTRACT. The Reference Model defined in ISO 13606-1 has attributes that can be used to specify the archetype to which any RECORD_COMPONENT within an EHR_EXTRACT conforms. The class RECORD_COMPONENT includes an attribute archety

37、pe_id to identify the archetype and node to which that RECORD_COMPONENT conforms. The meaning attribute, in the case of archetyped data, refers to the primary concept to which the corresponding archetype node relates. However, it should be noted that ISO 13606-1 does not require that archetypes be u

38、sed to govern the hierarchy of RECORD_COMPONENTS within an EHR_EXTRACT; the archetype-related attributes are optional in that model. It is recognised that the international adoption of an archetype approach will be gradual, and may take some years. Archetype repositories The range of archetypes requ

39、ired within a shared EHR community will depend upon its range of clinical activities. The total set needed on a national basis is currently unknown, but there might eventually be several thousand archetypes globally. The ideal sources of knowledge for developing such archetype definitions will be cl

40、inical guidelines, care pathways, scientific publications and other embodiments of best practice. However, de facto sources of agreed clinical data structures might also include: the data schemata (models) of existing clinical systems; the lay-out of computer screen forms used by these systems for d

41、ata entry and for the display of analyses performed; data-entry templates, pop-up lists and look-up tables used by these systems; shared-care data sets, messages and reports used locally and nationally; the structure of forms used for the documentation of clinical consultations or summaries within p

42、aper records; health information used in secondary data collections; the pre-coordinated terms in terminology systems. Despite this list of de facto ways in which clinical data structures are currently represented, these formats are very rarely interoperable. The use of standardized archetypes provi

43、des an interoperable way of representing and sharing these specifications, in support of consistent (good quality) health care record-keeping and the semantic interoperability of shared EHRs. The involvement of national health services, academic organizations and professional bodies in the developme

44、nt of archetypes will enable this approach to contribute to the pursuit of quality evidence-based clinical practice. The next key challenge is to foster communities to build up libraries of archetypes. It is beyond the scope of this part of ISO 13606 to assert how this work should be advanced, but,

45、in several countries so far it would appear that national health programmes are beginning to organize clinical-informatics-vendor teams to develop and operationalize sets of archetypes to meet the needs of specific healthcare domains. In the future, regional or national public domain libraries of ar

46、chetype definitions might be accessed via the Internet, and downloaded for local use within EHR systems. Such useage will also require processes to verify and certify the quality of shared archetypes, which are also beyond the scope of this part BS ISO 13606-2:2008ISO 13606-2:2008(E) ISO 2008 All ri

Communicating archetypes This part of ISO 13606 specifies the requirements for a comprehensive and interoperable archetype representation, and define

48、s the ODP Information Viewpoint representation for the Archetype Model and an optional archetype interchange format called Archetype Definition Language (ADL). This part of ISO 13606 does not require that any particular model be adopted as the internal architecture of archetype repositories, service

49、s or components used to author, store or deploy archetypes in collaboration with EHR services. It does require that these archetypes be capable of being mapped to the Archetype Model defined in this part of ISO 13606 in order to support EHR communication and interoperability within an EHR-sharing community. Overview of the archetype model This section provides a general informative description of the model that is specified in Clause 7. The overall archetype model consists of identifying information, a descriptio
