Which term describes the practice of linking patient identity to the health record across multiple encounters to facilitate retrieval?

• A. Disease index
• B. Master patient index
• C. Patient file index
• D. Encounter linkage index

Answer: (B)

Storing and linking a single patient identity across many visits to make it easy to retrieve all related records is done with a Master Patient Index. The MPI serves as a central directory that assigns a master patient identifier and ties every health record for that person together, even when names, demographics, or other identifiers vary across encounters. By using demographic data and matching rules, it helps consolidate duplicates and ensures you can pull up a patient’s complete history from multiple departments or facilities, improving continuity of care and data accuracy. Other terms describe different ideas: a disease index focuses on tracking patients by diagnosis for reporting, a patient file index isn’t the standard term for linking a person’s records across encounters, and an encounter linkage index would imply linking individual encounters rather than unifying the patient’s identity across the record.
