Which statement best describes when a reabstracting study is used?

• A. To monitor data completeness via re-abstracting of a sample
• B. To assess consistency among data abstractors using standardized charts
• C. To compare data across registries using primary site codes
• D. To verify the accuracy of coding through double abstraction

Answer: (A)

Reabstracting studies are a quality-check method used to gauge data quality in registries by re-collecting data elements from original source documents for a sample of records and comparing them with what’s in the registry. This helps estimate data completeness and identify missing or discrepant information, giving a measure of how complete and accurate the dataset is. While inter-abstractor consistency and coding validation are important concepts, the primary use of a reabstracting study is to monitor data completeness by re-abstracting a sample, making that option the best description.
