What Epic tool merges multiple patient records into a single master file?

• A. Patient Merge Tool
• B. MPI Merge
• C. Master Patient Index Consolidation
• D. Unified Patient Record

Answer: (B)

Merging duplicate patient records is handled within Epic by the Master Patient Index, and the specific function used to combine those records into one master is MPI Merge. The MPI is what maintains a single, enterprise-wide identity for each patient, so when duplicates exist, MPI Merge consolidates them into a single master patient record. This process pulls together demographic and clinical data from the duplicate records, links all encounters to the chosen master, and preserves data integrity across the system. The other named options aren’t standard Epic tools for this purpose, as they aren’t the established terminology or feature used to perform this consolidation.
