Health IT Services Group (HITSG) has its roots in Gamewood Data Systems, a successful Internet Service Providership (ISP). Gamewood Data Systems was founded in 1991 by Drs. Frank and Dugan Maddux after developing one of the first laboratory electronic data interchange programs for the dialysis industry.

Concurrently, Gamewood Data founders Frank and Dugan Maddux recognized a need for a kidney disease information clearinghouse and established RENALNET, one of the first medical web-sites in the world. RENALNET is the recipient of many awards since its inception in 1994. In 1995, the RENALNET concept was reposited in the permanent collection of the Smithsonian Institution’s National Museum of American History.

HITSG is the result of the research and development of the Acumen nEHR™ application, a web-based software solution developed by Dr. Frank Maddux for clinical medical practices. The concept of an easily accessible patient medical record, combined with the lessons of information availability learned in the development of RENALNET, was a catalyst for the development of a robust set of tools for the practicing physician and medical organizations. HITSG was formed as an independent entity when Gamewood, Inc. spun off its application service division in late 2006.

In 2007, Fresenius Medical Care North America (FMCNA) chose Acumen as the platform of choice to leverage the relaxation in the Stark and Safe Harbor Laws allowing a partial donation of technology to associated physicians.

On November 1, 2009 HITSG was acquired by FMCNA, operator of the nation’s leading network of dialysis facilities, to increase the integration of technology within the practice of Nephrology for FMCNA and all other dialysis companies and facilities.
