What is one of the elements specified in the quality control plan for the cancer registry?

Identifying the individuals involved is a critical element of the quality control plan for a cancer registry because it establishes accountability and ensures that there are designated personnel responsible for overseeing data collection, entry, and maintenance. This aspect is vital for maintaining the integrity and accuracy of the data, as it clarifies roles and responsibilities within the registry team. By knowing who is involved, the organization can better track the performance of these individuals, provide necessary training, and implement quality assessments effectively.

In contrast to this focus on personnel, the other options do not align with the specific elements of a quality control plan within a cancer registry. While financial considerations and patient confidentiality are important to different aspects of healthcare management, they do not directly relate to the accountability measures needed for ensuring the quality of data integrity in cancer registries. Changing treatment protocols may be relevant to clinical outcomes, but it falls outside the scope of quality control measures focused on registry operations and data management.
