Which practice helps ensure a single, consistent patient identity across EHR systems?

• A. Master data management.
• B. Data segmentation.
• C. Data archiving.
• D. Telemetry.

Answer: (A)

Master Data Management ensures a single, consistent patient identity across EHR systems by creating a unified, trusted view of all patient records. It establishes a Master Patient Index and uses data quality practices and identity-resolution rules (deterministic and probabilistic matching) to link duplicates and propagate updates so that demographic changes, encounters, and results are consistently tied to one patient across systems. This reduces duplicates, ensures continuity of care, and improves patient safety by preventing misidentification. Other options don’t address this cross-system identity unification. Data segmentation focuses on dividing data for access or analysis, not creating a single patient identity. Data archiving preserves older records but doesn’t resolve or synchronize identities across systems. Telemetry involves collecting device data, which is unrelated to integrating patient identities across EHRs.
