What should be communicated to participants about termination of their participation?

• A. Foreseeable circumstances and/or reasons for termination should be communicated.
• B. Termination details are optional and not required.
• C. Termination information should be provided only if requested.
• D. Termination data is confidential and not shared.

Answer: (D)

Confidentiality of information about ending a participant’s involvement is essential. Details about termination are sensitive personal data and should be kept private, shared only with individuals who need to know for safety monitoring, trial oversight, or regulatory reporting, and only to the extent required by the protocol and consent. This approach protects participant privacy and maintains trust. Other options imply broader or optional sharing, which could compromise confidentiality and isn’t in line with safeguarding participant data.
