Which topic is addressed by procedures for monitoring subject compliance?

• A. The plan for documenting and enforcing adherence to the treatment
• B. The methods for monitoring safety events
• C. The protocol for data entry validation
• D. How adherence to the treatment is tracked

Answer: (D)

Monitoring subject compliance is about how you measure and record whether participants follow the treatment as prescribed. The procedures specify the actual tracking of adherence—what methods you use to observe and document whether a subject is taking the study medication, such as pill counts, electronic monitoring, patient diaries, or structured interviews. This focus on measuring and recording adherence supports data integrity and participant safety, since knowing who followed the regimen helps interpret efficacy and safety results and identify potential protocol deviations.

The other ideas relate to different aspects: planning how to document and enforce adherence describes a preparatory or enforcement approach rather than the act of tracking adherence itself; monitoring safety events concerns safety data and adverse events; and data entry validation is about ensuring the accuracy of data in the system.
