Typen på denne publikation fremgår af forsiden. Der kan være tale om: Dansk standard standard, der er udarbejdet på nationalt niveau, eller som er baseret på et andet lands nationale standard, eller standard, der er udarbejdet på internationalt og/eller europæisk niveau, og som har fået status som dansk standard DS-information publikation, der er udarbejdet på nationalt niveau, og som ikke har opnået status som standard, eller publikation, der er udarbejdet på internationalt og/eller europæisk niveau, og som ikke har fået status som standard, fx en teknisk rapport, eller europæisk præstandard DS-håndbog samling af standarder, eventuelt suppleret med informativt materiale DS-hæfte publikation med informativt materiale Til disse publikationstyper kan endvidere udgives tillæg og rettelsesblade DS-publikationsform Publikationstyperne udgives i forskellig form som henholdsvis fuldtekstpublikation (publikationen er trykt i sin helhed) godkendelsesblad (publikationen leveres i kopi med et trykt DS-omslag) elektronisk (publikationen leveres på et elektronisk medie) DS-betegnelse Alle DS-publikationers betegnelse begynder med DS efterfulgt af et eller flere præfikser og et nr., fx DS 383, DS/EN 5414 osv. Hvis der efter nr. er angivet et A eller Cor, betyder det, enten at det er et tillæg eller et rettelsesblad til hovedstandarden, eller at det er indført i hovedstandarden. DS-betegnelse angives på forsiden. Overensstemmelse med anden publikation: Overensstemmelse kan enten være IDT, EQV, NEQ eller MOD IDT: Når publikationen er identisk med en given publikation. EQV: Når publikationen teknisk er i overensstemmelse med en given publikation, men præsentationen er ændret. NEQ: Når publikationen teknisk eller præsentationsmæssigt ikke er i overensstemmelse med en given standard, men udarbejdet på baggrund af denne. MOD: Når publikationen er modificeret i forhold til en given publikation.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard. CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached. CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

5 Foreword This document (CEN/TS :2005) has been prepared by Technical Committee CEN/TC 251 Health Informatics, the secretariat of which is held by SIS. This is part four of the multi part standard EN 14822: Health informatics - General purpose information components with the following parts: Part 1: Overview Part 2: Non-Clinical Part 3: Clinical Part 4: Message headers According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. 3

6 Introduction Many previous messaging and information structure standards for health have overlapping parts with a number of objects 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 message structures for different purposes. This approach 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 Standards for messages. This Technical Specification is aiming to provide such a set of components and has been developed jointly with a new European Standard for Service Request and Report messages that is using the components defined herein. Another important background to the development of this Technical Specification has been the wish for a harmonisation of information models for health developed in Europe and the USA expressed in the collaboration 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 ISO 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 open spirit of collaboration. This Technical Specification includes a large number of objects which are technically identical 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 HL7 is not. CEN wishes to express its gratitude towards HL7 experts for generously sharing their models with the European expert team. This part 4 document is definition of a set of message header General Purpose Information Components. 4

7 1 Scope It is now widely or even universally accepted that computer systems that are used within healthcare to record information about the care given to patient s need to share that information with other computer systems and their users. In order that computer systems may share information effectively there is a requirement that the communicating parties, and particularly their computer systems have a common understanding of how the information which they are sharing is represented. This sharing of representation needs to take place at a number of levels, most notably at the data representation or syntactic level which is the subject of CEN/TS 14796, but also at the macro or semantic level where groupings of data are used to provide a context or set of contexts for the data. This part 4 of the standard is limited to descriptions of components concerned with messaging, and in particular the message and batch headers. 2 Normative References Not applicable. 3 Terms and Definitions For the purposes of this Technical Specification, the following terms and definitions apply. 3.1 batch collection of messages 3.2 communicating party person, organisation or device which acts in the role of a sender or receiver of a communication 3.3 communication techniques for the effective transmission of information, ideas, etc. [Longmans 1995] 3.4 healthcare agent healthcare person, healthcare organisation, healthcare device or that performs a role in a healthcare activity 3.5 message communication in writing, speech or by signals 3.6 organisation unique framework of authority within which a person or persons act, or are designated to act towards some purpose NOTE Groupings or subdivisions of an organisation may also be considered as organisations where there is need to identify them for information interchange.
