How is EHR data typically shared across settings?

• A. Data are accessible and transferable across settings
• B. Data are stored locally only
• C. Data are not shareable
• D. Data are irrelevant to care teams

Answer: (A)

Interoperability is the ability of different EHR systems to exchange and use patient information. In practice, this means data are accessible and transferable across settings—hospitals, clinics, labs, specialists, and home health—so the entire care team can see a complete, up-to-date record. This supports continuity of care, safer transitions, medication reconciliation, and fewer duplicate tests, because clinicians can view core elements like demographics, medications, allergies, problem lists, labs, imaging results, and care plans from other settings. Standards such as HL7, FHIR, and CCD, along with health information exchanges, enable this exchange while maintaining privacy and security through proper authorization. If data were stored locally or not shareable, essential information would be siloed, leading to gaps in care and safety risks. Data are not irrelevant to care teams; they are crucial for coordinated patient management.
