Which statement best describes essential records retention and accessibility?

• A. Records may be destroyed immediately after the trial ends.
• B. Records must be encrypted.
• C. Essential records must remain available, accessible, and readable for the required retention period.
• D. There is no retention requirement.

Answer: (C)

In Good Clinical Practice, essential records from a clinical trial must be kept and be readable and retrievable for the full retention period established by the protocol and regulatory authorities. The point here is that retaining and ensuring access to these documents is crucial for verifying how the trial was conducted, ensuring participant safety, and supporting audits or inspections. This means records should be preserved in a way that they remain legible, intact, and able to be accessed when needed, even long after the trial ends.

Destroying records right after the trial ends would prevent regulators and sponsors from verifying the study and could violate retention requirements. While protecting privacy and confidentiality is important, requiring that every essential record be encrypted is not universally mandated in all situations; the appropriate security and documentation controls should be applied, but encryption alone is not the sole retention standard. And there is indeed a retention requirement; saying there’s none would be incorrect.
