What Is a Data Clarification Form in Clinical Trials?

Data Clarification Forms  (DCF) are used in clinical trials to clarify and resolve missing data or discrepancies in data collected during the trial. It's a standardized form that the clinical research sponsor or organization uses to request the investigator for additional information or clarification on specific data points.

A clinical trial sponsor sends the data clarification form to the study site or researcher, with a timeframe for completion. The researcher responds to the DCF request by entering the required information and sending it back to the sponsor.

Following that, the sponsor reviews the data to ensure it is correct and complete; if it is, it is entered into the clinical trial database.

What’s the Purpose of Data Clarification Forms?

The main purpose of the data clarification form is to ensure the integrity of clinical research data.  It reviews the accuracy, completeness, and reliability of the data collected during the research.

DCFs also foster collaboration and communication between the clinical research sponsor and the investigator.

The DCF process involves the sponsor informing the investigator about incorrect or missing data. The investigator examines the data, and both parties agree on the next steps to ensure the clinical research is accurate.

What Should be Included in a Data Clarification Form?

A typical data clarification form contains fields that allow the sponsor to collect additional information about specific data points, this includes:

  • Participant ID
  • Date of Query
  • Query number (Field requiring clarification)
  • Query description (reason for the clarification)
  • Additional information or clarification (link, media, or text)
  • Deadline for response.
