Health Information Exchange (HIE) refers to the process of reliable and interoperable electronic health-related information sharing conducted in a manner that protects the confidentiality, privacy, and security of the information. Essential to this process is the capability to employ nationally recognized standards as they are established incrementally, further enabling interoperability, security, and confidentiality of the information as well as authorization of those who access the information.
HIE supports the sharing of health-related information to facilitate coordinated care through the use of EHRs. HIE can also provide key information to individuals to promote health and wellness, and can be used to support research, public health, emergency response, and quality improvement. Additionally, HIE enables the sharing of health-related information among health care organizations and with individuals on a local, regional, and national basis. This interplay of electronic health records and health information exchange is an important component in establishing the basics of an infrastructure that will become the Nationwide Health Information Network (NHIN).

Wisconsin Relay of Electronic Data (WIRED) for Health
This project will build substantial health information exchange capacity statewide to support providers' meaningful use of electronic health records and enable efficient, appropriate, and secure flow of information to optimize decisions for health. The approach is to plan, develop, and implement interoperable, standards-based, secure electronic exchange of patient and health data. (For project details, visit WIRED for Health.)
