A Colorado study of ambulatory practices found no significant reduction in the number of tests ordered or in the cost of tests among the participants of a Health Information Exchange (HIE). The Study analyzed claims data from Rocky Mountain Health Plans, a leading health plan in the market, for 306 providers in 69 practices in Mesa County, CO. The study compared the number of tests ordered and their costs before and after the providers joined the HIE, which was launched in 2005 by Quality Health Network (QHN). By 2010, 85 percent of the providers in the area were participating in the HIE. The study was published in the Journal of the American Medical Informatics Association.
