Which term describes an electronic system for sharing patient medication lists?

• A. Health Information Exchange
• B. EHR/EMR
• C. Verbal Communication
• D. Paper-Based Transmission

Answer: (B)

The ability to share patient medication lists electronically across different care settings is provided by a Health Information Exchange. HIEs are designed for interoperable data sharing between organizations, so clinicians in hospitals, clinics, home health, and pharmacies can access up-to-date med lists and other important information during transitions of care. This shared access helps prevent medication errors, duplications, and adverse interactions when patients move between providers. An EHR/EMR, by contrast, is an electronic record kept within a single organization and isn’t primarily about exchanging data with other systems. Verbal communication or paper-based transmission are non-electronic and lack the secure, standardized sharing capability essential for cross-setting medication list access.
