AT and T is collaborating with the State of Tennessee to provide the first state wide health information exchange. The Tennessee Information Infrastructure eHealth Exchange Zone aims at securely transmitting detailed patient information between medical professionals, the telecommunications company said Monday.

It will also make it easier for doctors to access medical histories, prescribe medicines over the Internet and transfer images like X-rays, MRIs and CT scans. Doctors find it a way to improve patient safety that will reduce their spending and enhance the quality of care for Tennessee's 6 million residents.

Currently, the system is still under development but once it is fully established, the AT and T and the state will begin accepting applications from various health care providers. This broadband network will be available in all 95 counties in the state.

Soon the network will expand in other states and will provide platform for interstate information sharing networks in the future. It will be highly useful for doctors to remotely evaluate patients in rural areas who have less access to medical facilities.

AT and T will build a Virtual Private Network (VPN)-based portal that will also link to the state Department of Health for access to the immunization and disease registry, death certificate processing and medical license renewals.

San Antonio-based AT and T is also working with Covisint, a division of Compuware Corp., which will supply its OnDemand Platform to the project. Covisint's system has the ability to centralize, automate and streamline access to health information. Physicians state wide will be able to access health-information applications by signing on through this platform.
