In 2014, the Texas Health Services Authority (THSA) partnered with eHealth Initiative to measure progress to date and establish a baseline going forward for health information exchange (HIE) in the state of Texas. As has become the case nationally, many HIEs in Texas have moved out of early developmental stages and have brought their resources to bear on the difficult tasks of expanding networks, increasing clinical usage, and building out services. This report summarizes findings from a landscape survey of Texas HIEs.
