Health information exchange

Health information exchange

Health information exchange (HIE) is defined as the mobilization of healthcare information electronically across organizations within a region or community.

HIE provides the capability to electronically move clinical information between disparate health care information systems while maintaining the meaning of the information being exchanged. The goal of HIE is to facilitate access to and retrieval of clinical data to provide safer, more timely, efficient, effective, equitable, patient-centered care.

Formal organizations are now emerging to provide both form and function for health information exchange efforts. These organizations (often called Regional Health Information Organizations, or RHIOs) are ordinarily geographically-defined entities which develop and manage a set of contractual conventions and terms, arrange for the means of electronic exchange of information, and develop and maintain HIE standards. []


Some of the oldest RHIO's actually date back to the 1990s. The [ eHealth Initiative] ranks the [ Indiana HIE] as the most advanced and successful.

In 1994, with funding from the [ National Institutes of Health] and the [ National Library of Medicine] , the Regenstrief Institute Medical Informatics division extended the RMRS to the Indiana Network for Patient Care (INPC), a city-wide clinical informatics network. []

All INPC participants now deliver registration records, all laboratory tests, and all UB92 records (diagnosis, length of stay, and procedure codes) for hospital admissions and emergency room visits to separate electronic medical record vaults in a central INPC server located at Wishard Hospital. The message exchange standard that is used is HL7. The computer system standardizes all clinical data as it arrives at the INPC vault, laboratory test results are mapped to a set of common test codes LOINC with standard units of measure, and patients with multiple medical record numbers are linked. Each institution has the same file structure and shares the same term dictionary which contain the codes, names (and other attributes) for tests, drugs, coded answers, etc. When a patient is seen in any of the 11 emergency rooms operated by the consortium hospitals, and the patient consents, the information from all of these institutions about one patient can be presented as one electronic medical record. []

One of the largest, actively functioning, and few self-sustaining Health Information Exchanges involves the same group of medical informaticists from the [ Regenstrief Institute] in collaboration with the major hospital systems in the region. It is called the [ Indiana Health Information Exchange] . The first services delivered by IHIE include electronic delivery of test reports to physician offices using faxes, printers, or an electronic/ web based mail box (DOCS4DOCS Clinical Messaging System). According to their own [ website] , their aim is to:
* Improve the quality, safety, and efficiency of health care in the state of Indiana ,
* Create unparalleled research capabilities for health researchers,
* Exhibit a successful model of health information exchange for the rest of the country.

The Michiana Health Information Network located in northern Indiana was established in 1999. Since its inception the exchange has been able to successfully operate without grant funding as is self sustaining today. The network provides electronic result delivery with push technology, interface services for physician practices EHRs and institutional software, it's own electronic health record and a series of products supporting clinical registries and health quality improvement. MHIN is dedicated to the improvement of care and the reduction of medical cost in the Michiana community.
