What is one of the main purposes of record linkage in cancer registries?

One of the main purposes of record linkage in cancer registries is to enhance casefinding. Casefinding involves identifying all relevant cancer cases within a specific population to ensure accurate data collection and reporting. Record linkage allows registries to connect various data sources, such as hospital records, pathology reports, and treatment databases, to create a comprehensive picture of cancer incidence and outcomes.

By utilizing record linkage, cancer registries can cross-reference data from different organizations or systems, helping to ensure that all cases are captured, including those that may not have been reported directly. This thorough identification process is crucial for understanding cancer trends, improving patient care, and developing effective public health initiatives. The accuracy and completeness of cancer registries rely heavily on efficient casefinding methods supported by robust record linkage practices.
