The operational network formerly known as the Nationwide Health Information Network (NwHIN or NHIN) Exchange is now known as the eHealth Exchange. The ONC and the Coordinating Committee have officially designated
The Sequoia Project
as the legal entity that will operationally support the eHealth Exchange. The Sequoia Project eHealth Exchange Support Staff operate under the direction of the eHealth Exchange Coordinating Committee.
What is the eHealth Exchange (formerly the Nationwide Health Information Network)?
The eHealth Exchange (formerly the
Nationwide Health Information Network
) is a set of standards, services and policies that enable secure health information exchange over the Internet. The network will provide a foundation for the exchange of health information across diverse entities, within communities and across the country, helping to achieve the goals of the HITECH Act. This critical part of the national health IT agenda will enable health information to follow the consumer, be available for clinical decision making, and support appropriate use of healthcare information beyond direct patient care to improve population health.
What is the eHealth Exchange Specifications Factory?
The HITECH Act highlights the need for standards and interoperability specifications to support health information exchange. The role of the Spec Factory is to develop production-
interoperability specifications based upon existing industry standards, where possible, to support the business and clinical use cases that could be operated in production by the Exchange. In the event that existing industry standards don't exist or are inadequate, the Spec Factory creates new specifications, and then works with appropriate industry Standards Development Organizations (SDOs) to move the new efforts into industry standards when possible. One example of this is the IHE XCPD and BPPC specifications where created by the IHE after the eHealth Exchange (the NHIN at that time) created their
. Another example, is that OASIS
at the request of the Exchange to allow patients the ability to express their consent and other preferences, resulting in the
OASIS XSPA standard
The goals of the Spec Factory are as follows:
Maintenance of legacy nationwide health information network exchange specifications based on issues identified by implementers and other exchange stakeholders
Package exchange specifications into human readable format by building upon the visions for the nationwide health information network, while adhering to applicable governing body decisions and prioritizations to support use cases, business scenarios and implementations.
Generate Implementation Specification with an explicit description of the
Create guidelines for development of reference implementation
Who is the Spec Factory Team?
The Spec Factory consists of stakeholders who come from across the healthcare IT industry. Currently, the Spec Factory is made of the
Security and Privacy
workgroups. Each workgroup is responsible for providing subject matter expertise as well as maintenance for respective specifications. For more information, please on the workgroups, please visit the individual workgroup's site.
