Which statement best differentiates EMR, EHR, and HIE?

• A. EMR is a digital record for a single organization; EHR is a provider-enterprise record designed for sharing across settings; HIE enables the electronic exchange of health information between organizations.
• B. EMR is designed for sharing across settings; EHR is a single-organization record; HIE is a policy initiative.
• C. EMR is a paper-based record; EHR is an email; HIE is a health information exchange portal that is not digital.
• D. EMR, EHR, and HIE are the same thing.

Answer: (D)

The key idea being tested is how EMR, EHR, and HIE differ in scope and purpose. An EMR is the digital chart inside a single organization—think of it as the patient record kept by one clinic or hospital. An EHR is designed to be shared across settings and care providers, supporting continuity of care as a patient moves between primary care, specialists, labs, and hospitals. HIE refers to the network or infrastructure that enables the secure electronic exchange of health information between organizations, making it possible for disparate EMRs and EHRs to share data.

So the statement that EMR is a digital record for a single organization, EHR is a provider-enterprise record designed for sharing across settings, and HIE enables the electronic exchange of health information between organizations best captures these distinctions. The other descriptions mix up where sharing occurs, mischaracterize what an HIE is, or treat the terms as interchangeable.
