Since 2008, the Centers for Disease Control and Prevention's National Center for Health Statistics has fielded a mail survey of office-based physicians, the National Electronic Health Records Survey (NEHRS). ONC helps fund this supplement to track office-based physician adoption and the use of EHRs for health information exchange and patient engagement. Starting in 2010, the NEHRS's sample size was increased to allow for state-level estimates. The data set estimates each measure nationally and individually for each state and the District of Columbia beginning in 2010, unless otherwise noted.

Electronic prescribing (eRx) is a key component of the meaningful use of health IT to improve health care quality and lower costs. This dataset includes national and state eRx and health information exchange activity by community pharmacies and office-based health care providers active through the Surescripts Network. Surescripts is a health information network, and ONC procured electronic prescribing activity data conducted within its network from December 2008 through April 2014. The Surescripts network is used by the majority of all U.S. community pharmacies to rout prescriptions, excluding closed systems such as Kaiser Permanente. These include chain, franchise, and independently owned pharmacies. Data for annual percentages of new and renewal prescriptions routed through the Surescripts network exclude controlled substances.
