What are the different types of health information exchange?

The 3 Key Forms of Health Information Exchange

There are currently three key forms of health information exchange (HIE):

  • Directed Exchange: Directed exchange gives health care providers the ability to electronically send and receive secure information – such as such as laboratory orders and results, patient referrals, or discharge summaries – to other health care providers involved in a patient’s care over the Internet via encrypted, secure, and reliable messaging.
  • Query-Based Exchange: Query-based exchange gives health care providers the ability to find and/or request information on a patient from other providers and is often used for unplanned/emergency care.
  • Consumer Mediated Exchange: Consumer Mediated Exchange gives patients the ability to aggregate and manage their health information on the Internet. When in control of their own health information, patients can help transfer information between providers, correct inaccurate demographic, medical, or billing information, and track and monitor their own health.
