What is Health Information Exchange (HIE)?

• A. A private database for a single hospital
• B. A patient self-portal for personal health records
• C. The electronic sharing of health information between organizations to improve care coordination and outcomes
• D. A system for archiving paper charts only

Answer: (C)

Health Information Exchange is the electronic sharing of health information between organizations to improve care coordination and outcomes. It lets clinicians across hospitals, clinics, labs, and pharmacies access and exchange key patient data—such as medications, allergies, test results, problem lists, and discharge summaries—no matter where the care occurred. This enables safer, more coordinated care, reduces unnecessary testing, and supports smooth transitions when patients move between settings.

This isn’t a private database for a single hospital, and it isn’t simply a patient self-portal. It’s the connected network and standards that allow data to flow between multiple providers. It’s also not just about archiving paper charts; the focus is on electronic, timely exchange of information to inform decisions and improve outcomes, all while upholding privacy and security through appropriate consent, access controls, and auditing.
