Which element details the type and duration of the follow-up of subjects after adverse events?

• A. The type and duration of the follow-up of subjects after adverse events
• B. The procedures for eliciting reports of adverse events and intercurrent illnesses
• C. A description of the trial's randomization methods
• D. The monitoring plan for data entry timelines

Answer: (A)

In GCP, the protocol must specify how adverse events are followed after they occur, including what kind of follow-up is required and for how long it will continue. The element that states the type and duration of follow-up after adverse events directly captures this safety data need—it defines whether follow-up is done through visits, calls, or tests, and sets the time frame for monitoring until the event resolves, stabilizes, or reaches a predefined endpoint. This ensures consistent, complete collection of outcome information and proper safety assessment.

The other options describe different aspects: how adverse events are elicited and reported, how subjects are randomized, or how data entry timelines are monitored—none of which specify the follow-up plan after an adverse event itself.
