Which demographic fields are commonly used to match patients across Care Everywhere sites?

• A. Social media handle
• B. Favorite color and hometown
• C. Name, date of birth, and gender.
• D. Last visit timestamp

Answer: (C)

Matching patients across Care Everywhere hinges on stable, standard identifiers that are consistently captured in the medical record. The combination of name, date of birth, and gender provides a recognizable profile across different sites, allowing the system to link records from the same person with higher confidence. These fields are routinely collected, relatively stable, and help disambiguate individuals who might share similar names. In contrast, items like social media handles or favorite color and hometown aren’t official medical identifiers and aren’t consistently recorded or reliable for identity matching. A last visit timestamp is event-specific data and can vary between encounters or be missing, so it doesn’t serve as a dependable anchor for cross-site matching.
