What is the purpose of a Data Clarification Form (DCF)?

A Data Clarification Form (DCF) is an essential tool in clinical trials for ensuring the integrity and accuracy of data collected during the study. Its primary purpose is to question, clarify, or verify values reported in case report forms (CRFs). When discrepancies, unusual values, or missing data are identified, the DCF is used to communicate with the investigational site or specific personnel to resolve these issues. This helps maintain the quality of the data that will be analyzed for the study's outcomes.

The other choices do not accurately represent the role of a DCF. Summarizing patient data for final reporting involves different documentation processes, and recording data from adverse events is typically done through specific forms designed for that purpose, rather than a DCF. Generating informed consent documents is also a distinct process unrelated to data clarification activities. These functions are integral to clinical trials but serve different purposes from those of a DCF.
