16、ean Prestandard has been prepared by Technical Committee CEN/TC251 “Medical informatics”, the secretariat of which is held by IBN. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to announce this European Prestandard: Austr
17、ia, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the UnitedKingdom. The standard is published in two parts. This part specifies the information to be registered for information objects used in e
18、lectronic data interchange (EDI) in healthcare. Part 2 specifies the procedures for the operation of registration authorities. It incorporates a description of the software required to support the practical application of this European Prestandard. Annex A of this Part is normative. Annex B, Annex C
19、, Annex D, Annex E, Annex F, Annex G are informative.

The increased use of data processing and telecommunications capabilities has made possible the interchange o
23、f information in machine readable and machine processable formats. As automated interchange of information in healthcare increases it is essential to provide appropriate data interchange standards. All the methods of electronic data interchange (EDI) currently in use require the division of the info
24、rmation to be interchanged into suitable components, which are then identified in some way so that the receiving system can recognize them and process them appropriately. The components are assembled into messages, each message representing a transaction or being equivalent to a form in paper based
25、working methods. In the context of this European Prestandard a component may range from a data element, which is a unit of data normally considered to be indivisible, through logically associated groups of data elements, to complete messages. All are information objects. The rapid growth in EDI is r
26、esulting in the almost simultaneous development of systems each designed to satisfy the requirements of a particular application area. Unfortunately these uncoordinated developments also result in unnecessary variations in the manner in which information is represented, identified, named and describ
27、ed. The use of identical identifiers and names for different data concepts introduces a serious risk of misunderstanding and confusion when data is exchanged between application areas which have developed independently. In the English language the term “date of delivery”, for example, may represent
28、entirely different concepts for gynaecologists and couriers. This European Prestandard describes a procedure by which the components and messages required to facilitate the use of EDI in support of healthcare may be registered and allocated an internationally unique identifier. This European Prestan
29、dard also specifies how components when registered may be included in a widely available International Register which is so indexed and constructed that those designing EDI messages can ascertain easily whether a component or message which is suitable for their purposes already exists. If it is esta
30、blished that new components or messages are essential the procedures for registration specified in this European Prestandard are designed to encourage their derivation from existing entries with appropriate modifications thus avoiding unnecessary variations in the way similar data concepts are repre
31、sented. Registration will also enable synonyms, i.e. two or more information objects serving an identical function, to be identified. Perhaps most importantly, it will highlight the situations where similar or identical names are in use for EDI information objects which are significantly different i
32、n one or more respects. The procedures specified in this European Prestandard recognize that the development of EDI messages is a dynamic and fast moving process and may involve the use of more than one syntax. They are therefore designed to be syntax independent and also to minimize administrative
33、delay. This European Prestandard is based on work within CENTC251 which uses a domain information model (DIM) as a basis for the design of EDI messages. It also draws on work within ISO. 1 Scope This part of the European Prestandard specifies the information to be registered for information objects
34、used in EDI for the purpose of information interchange related to healthcare. The information objects and the information relating to them are recorded in a way which is designed to be independent of interchange format and to facilitate the use of the information objects to construct implementable m
35、essage specifications. This European Prestandard does not cover the registration of information objects which fall within layers1-7 of the Basic Reference Model of Open Systems Interconnection ISO7498, nor does it specify the data base software, programming languages, file organization, storage medi
36、a, etc., to be used for the establishment and maintenance of the Register. NOTEAlthough the scope of this European Prestandard is confined to EDI in support of healthcare the provisions are intended to be capable of application to EDI universally.ENV12537-1:1997 4 BSI 05-1999 2 Normative references

45、 Authority. The information specified inA.2.16 toA.2.18, andA.2.20 toA.2.25 of Annex A is generated during the process of registration. All the other information specified in Annex A shall be provided by the requesting organization.ENV12537-1:1997 BSI 05-1999 5 4.3 Character set Except as provided i
46、n the following paragraph an entry in the Register shall consist of the following characters only. They constitute the PrintableString specified in ISO/IEC8824 and they have been selected because they are consistently rendered on a wide range of equipment. 4.4 Extending the character set Where it is
47、 required to specify the value of another character string all the characters of the defined character string shall appear in the Register surrounded by the characters “whether they occur in the above set or not. However, it is important to recognize that such characters may not be displayed or prin
48、ted in the same way on all equipment, e.g. and $frequently share the same bit encoding. The possibility of an inconsistent rendering of the Register occurring when it is distributed in machine readable form shall therefore be carefully considered if characters not forming part of the above set are i
