member countries that are not currently part of the EU (Czech Republic, Hungary, Iceland, Malta, Norway, Slovakia, and Switzerland). CEN/TC 251  is the health informatics Technical Committee of CEN. At present there is only one comprehensive EHR interoperability standard in the world. This is the CEN ENV136063standard that was published in 1999/2000. It built upon the first CEN EHR standard, ENV12265, published in 1995. It was based almost entirely on the Good European Health Record (the original GEHR) but was never implemented. ENV13606 has had limited uptake due mainly to difficulties with implementation inherent in its single-level modeling approach. In November 2001, a decision was taken by CEN to revise 3“ENV” denotes a “Pre-standard” (soon to be renamed a “Technical Specification” to comply with ISO terminology) whilst “EN” denotes a full de jureEuropean standard. All CEN standards are ENVs for a period of three years which enables implementation experience and feedback before becoming a full standard. At the end of the three year period, a pre-standard can be converted without change to full EN status, or it can be revised to become an EN, or it can be scrapped.

ENV13606 and to adopt the openEHR4/GEHR archetype methodology5. An MOU was signed between CEN and the openEHR Foundation  to enable the Australian members of openEHR to participate in the revision project. The ENV13606 standard was in four parts but the revised EN13606 will consist of five parts: •Part 1: Reference Model– a generic information model for communicating one or more EHR extracts (or the entire EHR) of any subject of care (patient/consumer). •Part 2: Archetype Interchange Specification– a generic information model and language for representing and communicating the definition of individual instances of Archetypes. •Part 3: Reference Archetypes and Term Lists– a range of Archetypes reflecting a diversity of clinical requirements and settings, as a "starter set" for adopters and to illustrate how other clinical domains might similarly be represented (for example by health professional groups). •Part 4: Security Features– the information model concepts that need to be reflected within individual EHR instances to enable suitable interaction with the security components that are anticipated to be required in any future EHR deployment. •Part 5: Exchange Models– a set of models that build on the above parts and can form the basis of message-based or service-based communication. The revised CEN EN13606 will also include compliance with the HL7 CDA (Clinical Document Architecture) Release 2. This will form a very important harmonization bridge between Europe and the U.S.. A simple schematic diagram of this relationship between openEHR, CEN 13606, and HL7 CDA is: 4The openEHR EHR model is common framework and open specification for structuring, storing and
