OUR STORY
East Tennessee Health Information Network (etHIN), a non-profit community Health Information Exchange (HIE), was established in 2005 to serve the data exchange needs of the healthcare community. Healthcare providers have been using our robust exchange services to meet their data needs for more than 11 years.
etHIN provides a secure health information exchange technology platform to its Community of Care. This secure solution replaces traditional methods of sharing medical records such as faxing, calling, mailing, patient pick-up, and couriers. etHIN gives authorized providers immediate access to patients’ records from providers across the community, including hospitals and other physicians.
Many of the major hospital systems in the region participate in the network, along with numerous physicians’ groups, long term care and skilled nursing facilities, behavioral health providers, labs, and other providers of health care services. View our current Participants here.
WHERE WE ARE
etHIN is based in Knoxville, Tennessee and makes health information exchange available to all members of the healthcare community in its 23-county primary region and beyond. etHIN contains records of patients from all 95 Tennessee counties who have been treated in our region, along with records of patients from other states who were treated in our area. Patient data from certain states is available in etHIN through the nationwide eHealth Exchange and Patient Centered Data Home networks.
As new participants join etHIN, our Community of Care expands to encompass additional areas of Tennessee. etHIN adheres to all state and federal guidelines that protect the rights of individuals who obtain health care in Tennessee.
