What is master data management in healthcare?

• A. Managing only clinical trial data.
• B. Deleting duplicate patient records without reconciliation.
• C. Ensuring consistent and accurate core data (e.g., patient, provider) across systems.
• D. Creating new patient identifiers in every system.

Answer: (C)

Master data management in healthcare focuses on creating and maintaining a single, trusted source of truth for the most important data elements—such as patients, providers, and facilities—that are used across multiple systems. It combines governance, standard definitions, data quality rules, and identity matching to ensure these core records are accurate, complete, and consistent everywhere they’re used, from EHRs to scheduling, billing, and reporting. This uniformity reduces duplicates, reconciles conflicting information, and supports reliable interoperability, analytics, and patient safety. That’s why the best description is ensuring consistent and accurate core data across systems. Other options miss the point: limiting scope to clinical trial data is too narrow; deleting duplicates without reconciliation can destroy or misalign information; creating new patient identifiers in every system fragments identity rather than harmonizing it.
