The Government Accountability Office (GAO) interviewed federal and state officials and reviewed survey data from providers to learn how the use of electronic health information exchange changed since the enactment of the Health Information Technology for Economic and Clinical Health (HITECH) Act in 2009. GAO found that the use of electronic exchange among hospitals and physicians increased in recent years but use among small and rural hospitals was lower than that of other hospitals. This finding may be because small and rural providers are less likely to have the financial and technical resources to participate in electronic exchange—such as adequate IT staff and sufficient access to broadband internet.
