Which data quality characteristic is NOT typically assessed in a cancer registry?

Cost-effectiveness is not typically a characteristic assessed in a cancer registry's data quality evaluation. When measuring data quality in the context of cancer registries, essential attributes such as timeliness, completeness, and accuracy are primarily focused on.

Timeliness refers to how quickly data is collected and processed after diagnosis or treatment, ensuring that the information reflects the current state of cancer care and treatment outcomes. Completeness assesses whether all necessary data elements have been captured adequately, indicating the registry's ability to provide a comprehensive overview of cancer cases in a given population. Accuracy focuses on whether the data recorded is correct and reflects true clinical and demographic information of patients.

While cost-effectiveness is an important consideration for healthcare systems and can influence how resources are allocated in cancer registries, it does not directly relate to the quality of the data being captured and maintained within the registry. This distinction highlights why cost-effectiveness stands apart as not being a standard data quality characteristic assessed within cancer registries.
