Which statement best reflects data integrity in integrated health information systems?

• A. Data does not need to be standardized
• B. Data must have a consistent interpretation
• C. Data can be interpreted differently across systems
• D. Data should never be shared

Answer: (B)

Data integrity across integrated health information systems hinges on ensuring that data are understood the same way no matter where they come from. When data have a consistent interpretation, a value like a lab result, a diagnosis code, or a measurement means the same concept and unit across all systems, enabling accurate aggregation, reliable reporting, and sound clinical decisions. This semantic consistency underpins interoperability: different systems can exchange data and users can trust that the meaning of each data element is preserved. Standardization of data elements, codes, and units supports this goal, but the core idea is that the interpretation must be uniform. If data could be interpreted differently in separate systems, the same numeric value or code could be read as something else, leading to errors in care, misinformed analytics, or faulty decision support. Sharing data is essential in integrated environments, provided governance ensures that interpretation remains consistent.
