What should be documented if a participant withdraws from a clinical trial?

• A. The participant's contact information
• B. Reasons for withdrawal and their potential impact on the study outcomes
• C. Feedback from the participant about the trial
• D. The date and time of withdrawal only

Answer: (B)

Documenting the reasons for a participant's withdrawal and analyzing their potential impact on study outcomes is a crucial component of clinical trial management. This documentation helps ensure that the integrity of the study is maintained and that any biases introduced by the withdrawal can be assessed. When a participant withdraws, understanding their reasons can provide insights into the treatment's safety and efficacy, as well as the overall participant experience. For example, if multiple participants withdraw for similar reasons, this may indicate a safety concern or a lack of tolerability associated with the intervention. Additionally, knowing the reasons allows researchers to evaluate if the withdrawal is related to the treatment or if it might be influenced by external factors. This information is vital for data analysis and for informing future research, regulatory filings, and communications with stakeholders. Other options, such as documenting the participant’s contact information, feedback, or simply the date and time of withdrawal, do not provide the depth of understanding required to evaluate the impact of withdrawals on the study and do not fulfill the ethical and scientific responsibilities of investigators. Thus, the most comprehensive and valuable documentation focuses on the reasons for withdrawal and their implications for the study.
