What is the background of the current release?

The HL7 EHR-S Functional Model, which was approved in July, 2004 as a Draft Standard for Trial Use (DSTU), has undergone a series of enhancements in the past two years, as it became a fully approved American National Standards Institute (ANSI) standard. A broad constituency – including intensive outreach to industry, care providers, and healthcare organizations – has worked to refine the initial EHR-S Functional Model. This version reflects the changes made as part of the reconciliation process on a committee level ballot, and two subsequent membership level ballots. The HL7 EHR-S Functional Model was promoted to an ISO International Standard after passing HL7 consensus ballot as a normative standard and achieving ANSI approval. This promotion follows the process outlined in the ISO/HL7 Pilot Agreement. Learning important lessons from the ballot process, a Functional Model with a clearer, more simplified list of functions, has been created. The HL7 EHR System Functional Model provides a reference list of functions that may be present in an Electronic Health Record System (EHR-S). The function list is described from a user perspective with the intent to enable consistent expression of system functionality. This EHR-S Model, through the creation of Functional Profiles, enables a standardized description and common understanding of functions sought or available in a given setting (e.g. intensive care, cardiology, office practice in one country or primary care in another country).
