Which approach best supports data integrity in health IT systems?

• A. Encrypting data at rest.
• B. Validation and reconciliation processes.
• C. Regular folder archiving.
• D. Data anonymization for all use.

Answer: (B)

Maintaining data accuracy and consistency across health IT systems is best addressed by validation and reconciliation processes. Validation checks ensure data meet defined rules—correct formats, appropriate value ranges, required fields, and proper data types—so errors are caught as data enter or move through workflows. Reconciliation compares data across different systems or over time, highlighting and helping correct discrepancies such as duplicates, missing records, or mismatched identifiers, which keeps information aligned from the EHR to labs, billing, and analytics. Together, these practices directly uphold data integrity, ensuring decisions, reporting, and patient safety rely on trustworthy data. Encryption at rest protects confidentiality rather than data accuracy, while regular folder archiving or data anonymization address storage or privacy concerns—not the ongoing integrity of the data itself.
