Audit Trail Section

An Audit Trail section focuses on the traceable record of data creation and changes: who or what changed information, when, and—where required—why. It is narrower than a full Computerized Systems section and should not be used as a substitute for broader system controls.

Quick answer

An Audit Trail section explains how creation and changes to electronic trial records remain traceable and reviewable without obscuring the original information.

Key details

Core IssueICH E6(R3) expects changes to trial data and source records to be traceable and treats audit trails and relevant metadata as part of maintaining data integrity across computerized systems.

Important caveats

Scope Boundary

Audit-trail controls are one part of computerized-system and data-governance requirements. Do not imply that an audit trail alone establishes overall system validation, security, or data quality.

Further guidance

Content

State which systems or records use audit trails, what events and metadata are captured, how audit trails are protected and retained, and when review is expected according to risk and applicable procedures.

Purpose

Make change history reconstructable so data review and oversight can distinguish original entries from later modifications.
