Cancer Registry Practice Test

Record linkage helps ensure accurate mortality data by?

Correctly matching individuals across data sources to determine vital status Increasing population counts Removing mortality data Isolating records from different hospitals

Correct Answer:

Increasing population counts

Explanation:

Record linkage is the process of accurately identifying and linking records that refer to the same person across multiple data sources, such as a cancer registry, death certificates, hospital records, and national death indexes. This enables you to determine the person’s vital status (alive or deceased) and capture the date of death when applicable. By combining information from different sources, mortality status can be verified, gaps filled, and inconsistencies resolved, leading to more complete and accurate mortality data and better survival analyses. It isn’t about increasing population counts, removing mortality data, or isolating records; those would compromise data quality and follow-up.
