What is a health information exchange (HIE)?

• A. A system enabling the sharing of health information among disparate organizations
• B. A project management methodology
• C. A type of encryption
• D. A vendor contract template

Answer: (A)

Sharing health information across organizations is the essence of a health information exchange. An HIE provides a framework and technical infrastructure that allows different health care providers, laboratories, and other authorized participants to access and securely share a patient’s clinical data when needed. This enables a more complete view of a patient’s history, supports safer and more coordinated care, and reduces unnecessary duplicate tests or delays during transitions between care settings. To work well, HIEs rely on interoperability standards, patient consent and privacy protections, access controls, and auditing to ensure data is shared securely and appropriately.

This description fits best because it centers on enabling the exchange of health information among disparate organizations. It isn’t about managing projects, encrypting data in isolation, or creating contract templates, which are separate concepts.
