The European Committee for Standardization (CEN) Standard Architecture for Healthcare Information Systems (ENV 12967), Health Informatics Service Architecture or HISA is a standard that provides guidance on the development of modular open information technology (IT) systems in the healthcare sector. Broadly, architecture standards outline frameworks which can be used in the development of consistent, coherent applications, databases and workstations. This is done through the definition of hardware and software construction requirements and outlining of protocols for communications.〔Engel, Kjeld. Blobel, Bernd. Pharow, Peter. (2006) Standards for Enabling Health Informatics Interoperability, ''Ubiquity: Technologies for Better Health in Aging Societies'' IOS Press〕 The HISA standard provides a formal standard for a service-oriented architecture (SOA), specific for the requirements of health services, based on the principles of Open Distributed Processing.〔Klein, Gunnar. Sottile, Pier Angelo. Endsleff, Frederik. (2007) Another HISA - The new standard: Health Informatics - Service Architecture,Studies in Health Technology and Informatics,129(Pt 1):478-82〕 The HISA standard evolved from previous work on healthcare information systems architecture commenced by Reseau d’Information et de Communication Hospitalier Europeen (RICHE) in 1989, and subsequently built upon by a number of organizations across Europe.〔Kalra,Dipak. (2002) Clinical Foundations and Information Architecture for the Implementation of a Federated Health Record Service, University College, London〕 == Development of Health Informatics Service Architecture EN/ISO 12967 == The HISA standard was developed by CEN Technical Committee (TC) 251, the technical committee for Health Informatics within the federation of European national standards bodies (CEN).〔Klein, Gunnar. Sottile, Pier Angelo. Endsleff, Frederik. (2007) Another HISA - The new standard: Health Informatics - Service Architecture,Studies in Health Technology and Informatics,129(Pt 1):478-82〕 The CEN/TC 251 was made up of four working groups, covering: information models; systems of concepts and terminology; security; and technologies for interoperable communication.〔Kalra,Dipak. (2002) Clinical Foundations and Information Architecture for the Implementation of a Federated Health Record Service, University College, London〕 Working Group I were responsible for information models and completed the specifications that became the HISA standard. Working Group I worked with experts from across Europe, plus contributors from Australia and the United States in the development and finalization of ENV 12967. The CEN HISA standard was adopted by the International Organization for Standardization (ISO) in 2009, with the stated aim of ISO 12967 being to provide guidance on: * the description, planning and development of new electronic health systems; and * the integration of existing electronic health systems, both intra- and inter-organizationally, through architecture that integrates common data and business logic into middleware, which is then made available throughout whole information systems.〔(【引用サイトリンク】url=http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=50500 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Health Informatics Service Architecture」の詳細全文を読む スポンサード リンク
