Which Epic feature helps ensure that each patient has a unique chart and supports standardized patient identifiers?

• A. MPI Deduplication
• B. Chart Uniqueness Utility
• C. Patient Identifier Manager
• D. Duplicate Chart Prevention

Answer: (A)

Creating a single, reliable patient identity across the organization hinges on managing the Master Patient Index and running a deduplication process. The Master Patient Index is the authoritative directory that assigns a unique enterprise-wide identity to each patient and ties all demographic data to that identity. MPI Deduplication is the feature that actively checks records, uses matching rules to identify potential duplicates, and then merges them under one canonical MPI ID, applying survivorship logic to decide which data to keep. This results in one chart per patient and consistent identifiers across facilities and encounters, so you don’t end up with multiple charts for the same person or mismatched identifiers. Other options describe broader utilities or generic prevention ideas, but they don’t capture the specific mechanism Epic uses to enforce a unique, standardized patient identity across the system.
