The eHealth Exchange, formerly known as the ''Nationwide Health Information Network'' often abbreviated as the ''NHIN'' or ''NwHIN'', is an initiative for the exchange of healthcare information. It was developed under the auspices of the U.S. Office of the National Coordinator for Health Information Technology (ONC), and now managed by a non-profit industry coalition called HealtheWay. The exchange is a web-services based series of specifications designed to securely exchange healthcare related data. The NwHIN is related to the Direct Project which uses a secure email-based approach. One of the latest goals is to increase the amount of onboarding information about the NwHIN to prospective vendors of health care systems. The Office of the National Coordinator for Health Information Technology has been facilitating development of the NwHIN, which will tie together health information exchanges, integrated delivery networks, pharmacies, government, labs, providers, payors and other stakeholders into a "network of networks." A health care system participating in the NwHIN acquires an Object identifier (OID). The OID, issued by the ONC, allows the individual health care €system or vendor to receive and send messages to trusted entities within the NwHIN through an interface such as Mirth Connect or a custom-built Java UI. The NwHIN is built on open source code utilizing the Java platform. This creates a need for technical information sharing among programmers with the ONC also making information available. Former Health and Human Services Secretary Michael Leavitt has stressed, however, that the NwHIN will be a public-private venture. Foundations such as the Markle Foundation, the Robert Wood Johnson Foundation and the California HealthCare Foundation are now providing financial support for research and demonstration projects that could lead to advances in the development of a nationwide health information network.〔http://www.nhinwatch.com/performSearch.cms?channelId=6〕 The NwHIN is funded through the Office of the National Coordinator for Health Information Technology, the Health Resources and Services Administration, the Agency for Healthcare Research and Quality, the Centers of Medicare and Medicaid Services, the Centers for Disease Control and Prevention, and the Indian Health Service.〔HITECH Act, Section 3011.〕 ==NwHIN Participants== The stakeholders that participate in the NwHIN will be four broad classes of organizations: *Care delivery organizations (CDOs) that use electronic health records (EHRs). *Consumer organizations that operate personal health records (PHRs) and other consumer applications. *Health information exchanges (HIEs): multi-stakeholder entities that enable the movement of health-related data within state, regional or non-jurisdictional participant groups. *Specialized participants: organizations that operate for specific purposes including, but not limited to, secondary users of data such as public health, research and quality assessment. The specialized nature of these organizations means that they may require only a subset of the shared architecture (standards, services and requirements), processes and procedures used by the other participants. 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「EHealth Exchange」の詳細全文を読む スポンサード リンク
