Which data elements are critical for patient matching in Care Everywhere?

• A. Insurance details only
• B. Appointment history only
• C. Demographics, identifiers, and contact information
• D. Clinical notes only

Answer: (C)

Matching patients across Care Everywhere relies on using multiple identifying data elements together, because no single piece of information is unique enough on its own. Demographics like name, date of birth, and gender provide the basic identity clues, while identifiers such as a medical record number or other system-specific IDs tie records to the same person across different organizations. Adding current contact information—address, phone, and email—helps verify who the patient is and resolve ambiguities when demographic data could be shared by more than one person or may be outdated.

This combination gives the most reliable cross-system linkage, reduces duplicates, and lowers the chance of linking the wrong chart to a patient. Insurance details can change and aren’t unique, appointment history is contextual rather than identifying, and clinical notes may mention a patient but aren’t structured identifiers, so they’re not sufficient on their own for matching.
