Interoperability in electronic health records means that different EHR systems can exchange patient information, interpret it correctly, and use it in a consistent and meaningful way across care settings. This enables clinicians in one setting to access and understand data from another—such as tests, diagnoses, and medications—without compatibility issues, often through standardized formats and coding.

Storing data offline describes storage location rather than how information moves between systems. Encryption and security cover protecting data, which is essential but does not address cross-system communication or understanding. Using a single vendor may reduce the complexity of integration in one sense but does not demonstrate the ability to work with multiple, distinct systems, which is what interoperability aims for.
