Abstract Data interchange standards have become a critical link in building both hospital-based information management systems as well as broader-based patient-centered information systems. From its beginnings in 1987, Health Level 7 (HL7) has become the leading international standard for the message-based interchange of clinical data. The current version, Version 2.4, is based on an implicit model and uses a delimiter-based syntax. The presentation will present briefly the V2.4 standard, including an example message. Then the philosophy and process of Version 3, based on an object model, will be presented. What is gained in the transition to Version 3 will be discussed as well as where HL7 is in the migration to V3. The remainder of the session will include an update in the additional activities of HL7 beyond messaging standards and will include Clinical Data Architecture, Vocabulary, Clinical Content Object Working Group (CCOW), clinical templates, and Decision Support.
