Distinguish protocol amendments from deviations and how each is documented.

• A. Deviations are unplanned departures documented with rationale and impact
• B. Amendments modify the protocol with approvals; deviations are unplanned departures documented with rationale and impact
• C. Amendments modify the protocol with approvals and no documentation of deviations
• D. Neither require documentation

Answer: (B)

In protocol management, planned changes and unexpected events are handled differently to maintain governance and traceability. An amendment is a planned modification to the protocol that undergoes formal review and receives approvals before it is put into use; the change is documented with updated protocol text, version numbers, and the approval records. A deviation is an unplanned departure from the protocol as it is being carried out; it is documented after the fact with the rationale for the departure and an assessment of its potential impact on participant safety, data integrity, or study outcomes, along with any corrective actions taken. This approach keeps authorized updates clearly recorded and separately tracks unexpected issues so they can be reviewed and addressed. That’s why the statement describing amendments as modifying the protocol with approvals and deviations as unplanned departures documented with rationale and impact is the best fit.
