The Memphis-based MidSouth eHealth Alliance in 2004 received a federal grant to develop a demonstration data exchange platform with informatics professionals at Vanderbilt Medical Center. The exchange developed to link 14 emergency departments and primary care physicians, and has logged data on more than 7 million encounters for 2.8 million patients.

Now with the grant period ending, MidSouth eHealth Alliance has signed a multi-year contract to migrate to a since-commercialized version of the platform, called CareAlign, from Informatics Corp. of America in Nashville.

Terms of the contract, which will turn the demonstration program into a commercial HIE project, were not immediately disclosed. The alliance's database contains nearly 42 million chart documents including acute care discharges, emergency and outpatient encounter summaries, radiology reports and laboratory results. Clients include 16 hospitals with 14 emergency departments, and 16 primary care sites, all with diverse information systems.
