17、oreword This European Standard (EN 14822-1:2005) has been prepared by Technical Committee CEN/TC 251 “Health informatics”, the secretariat of which is held by SIS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, a
18、t the latest by April 2006, and conflicting national standards shall be withdrawn at the latest by April 2006. This is part one of a multipart standard under the heading: Health informatics - General purpose information components with the following parts: Part 1: Overview Part 2: Non-clinical Part
19、3: Clinical According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy
20、, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 14822-1:2005 (E) 4 Introduction Many previous messaging and information structure standards for health have overlapping parts with a number of objects
21、being defined in separate documents, sometimes with small variations making implementation of conformant applications more difficult. It therefore makes sense to define a set of general purpose components that can be used for definition of communication structures for different purposes. This approa
22、ch was suggested and approved as a strategy for CEN/TC 251 in the Short Strategic Study on message standards alignment in 1999 examining a set of five European prestandards for messages. This standard is aiming to provide such a set of components and has been developed jointly with a new European St
23、andard for Service Request and Report messages that is using the components defined herein. Another important background to the development of this European Standard has been the wish for a harmonisation of information models for health developed in Europe and the USA expressed in the collaboration
24、agreement entered March 2000 between CEN/TC 251 and HL7 (Health Level Seven, Ann Arbor. Michigan). The goal was set for a maximum degree of alignment while maintaining their independence and need to serve the business requirements of the respective markets but also to make the results available to I
25、SO for possible international standardization. HL7 have adapted a general strategy similar to CEN/TC 251 using information modelling expressed in UML (Unified Modelling Language) for their new standards and a lot of interaction and information sharing has occurred between CEN experts and HL7 in an o
26、pen spirit of collaboration. This European Standard includes a large number of objects which are technically similar to descriptions in draft documents of HL7, although partly described differently due to the fact that CEN is following the ISO rules for drafting and presentation of standards which H
27、L7 is not. CEN wishes to express its gratitude towards HL7 experts for generously sharing their models with the European expert team. EN 14822-1:2005 (E) 5 1 Scope This European Standard specifies General Purpose Information Components to be used in standards for information exchange and information
28、 models supporting various health specific business requirements. The components defined in this standard are the most commonly needed basic building blocks for such standardization but these components may require further specialisation and be complemented by other objects required for specific pur
29、poses not met by these generally useful components. Such standardization using these general purpose information components could be performed both on a European (CEN) level or be done nationally or for specific user communities regionally as well as internationally. This European Standard provides
30、an informative overview of this series of standards and includes rules for using the components defined in the other parts and on conformance claims. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply.

34、 components which are presented in EN 14822-1 and EN 14822-2 and have been selected to meet major requirements from existing European message standards and some projected requirements for other types of information exchange. EN 14822-1:2005 (E) 6 It is noteworthy that this document may be useful in
35、the design of interacting components in a local application as well as for remote communication across organisational boundaries. The information components defined in this series can support database design, interacting objects using SOAP (Simple Object Access Protocol), COM (Common Object Model) o
36、r CORBA (Common Object Request Broker Architecture) as well as traditional store and forward messaging systems. 5.2 General Purpose Information Components and the Health Level Seven RIM A General Purpose Information Component (GPIC) is a specification of a component of an information system or of a
37、communication between such systems and we may use a number of these components in order to build a larger systems or communications. In particular, the GPICs which are the subject of this multipart standard are generated so as to provide a set of generic templates for commonly encountered concepts t
38、hat are found in healthcare information systems and in the communication between such systems. Given that GPICs are a set of components that may be used in combination to describe a larger whole, there is a need to have consistency in the internal design principles of the GPICs and also in the exter
39、nal interfaces which allow components to be combined in a consistent manner. If such principles are rigorously adhered to it becomes easier to provide tools to support the development of messaging and other communication systems. Achieving the necessary degree of consistency in the internal design a
40、nd external interfacing of the GPICs has been facilitated by the use of the Health Level Seven (HL7) Reference Information Model (RIM). It shall be understood that this RIM is NOT a model of healthcare nor of healthcare records; rather it is a high level model of healthcare information elements and
41、the relationships between these elements. The RIM therefore provides us with an abstract model from which those elements that we need in order to design the relevant GPICs can be selected. In effect the RIM provides the basic building blocks from which we construct larger building blocks: the GPICs
42、(see Figure 1). EN 14822-1:2005 (E) 7 Figure 1 HL7 reference information model and GPIC design Figure 1 illustrates that RIM classes are being used to construct a number of different GPICs which may be further combined, either with additional RIM classes or other GPICs to make larger, more complex G
43、PICs. An example may be used to illustrate the basics of the process. The RIM contains a concept of person which could be used in GPICs which describe patients, doctors, nurses, next of kin, animal owners etc. A GPIC design will use those attributes of the Person class which are appropriate to the f
44、unction of the particular GPIC and then combine this with another RIM concept of Role to produce a tailored description of the person/role that describes the person playing the role of patient, nurse etc. The RIM provides the generic classes such as Act, Entity and Person (see next subclause) togeth
45、er with a set of generic attributes with their data types and rules concerning the number and type of relationships with other RIM classes. The GPIC takes from the RIM those classes, attributes and class associations that are required and imposes constraints by defining: Health Level 7 Reference Inf
46、ormation ModelGPIC AGPIC BGPIC C GPIC DGeneral PurposeInformation ComponentsEN 14822-1:2005 (E) 8 the precise purpose of the combination of RIM classes, i.e. what is the scope of the GPIC; the sub-set of attributes which are being used in each class. For example, the use of the Person attribute dece
47、ased_time may be appropriate to the concept of Patient but not to the concept of Healthcare Professional; the exact purpose of each attribute. For example in different GPICs, the use of the attribute code derived from the Entity class may be used to provide a coded description of a very wide range o
48、f things such as the type of medicinal product pack or the kind of care setting or the type of device etc.; limitations upon data types associated with each attribute. For example, although most of the RIM attributes are associated with precise data types there are many attributes where a wide range
49、 of data types are allowed. This is especially prevalent in describing time where there may be requirements for a date/time, a date/time range, a period of time, and so on. In designing a GPIC the use of each attribute is more focussed. This permits the imposition of constraints upon the data types and also of the underlying vocabulary sets associated with coded attributes. 5.3 Health Level 7 (HL7) Reference Information Model 5.3.1 Introduction The General Purpose Information Components described within this multi-part standard conform to HL7s Re
