Final answer:
The cancer registrar must keep a record of disclosure when records are made available to the state/central cancer registry and researchers conducting special studies.
Step-by-step explanation:
The cancer registrar must keep a record of disclosure (an accounting of what, where, when, to whom and for what purpose information was distributed) when records are made available to:
- The state/central cancer registry.
- Researchers conducting special studies.
- Both (a) and (b).
- Neither (a) nor (b).
Both the state/central cancer registry and researchers conducting special studies require the cancer registrar to keep a record of disclosure. This ensures accountability and transparency in the sharing of information. The record of disclosure includes details such as the recipient of the information, the purpose of the disclosure, and when and where it was distributed.
