Which of the following is NOT a key data quality measure for safety data?

• A. Cost
• B. Timeliness
• C. Accuracy
• D. Completeness

Answer: (A)

Data quality for safety information is judged by how up-to-date the data is, how accurately it reflects what happened, and whether all needed information is present. Timeliness ensures decisions aren’t based on outdated facts; accuracy prevents errors in risk assessments; completeness avoids gaps that could hide important safety signals. Cost, while important for planning and data collection, does not describe the quality of the data itself—the money spent or saved does not indicate whether the data correctly reflects real events or is complete and timely. Therefore, cost is not a key data quality measure for safety data.
