In clinical research, data quality is not only a technical requirement but a cornerstone for regulatory approval and patient safety. According to ICH, EMA, and the FDA, every data modification must be traceable.
This is where an audit trail plays a central role, ensuring transparency, integrity, and reliability in digital data management.
What is an audit trail?
An audit trail is the chronological record of every action taken on clinical data, including entries, edits, and deletions. As outlined in FDA 21 CFR Part 11 and EMA guidelines on eSource, audit trails ensure that nothing is lost or altered without documentation.
They allow sponsors, CROs, and inspectors to reconstruct the full data history —a fundamental requirement during audits and inspections.
What is an audit trail in electronic health records?
In electronic medical records (EHR/EMR) and eCRFs, the audit trail documents:
- Who performed the action (user).
- When it was done (timestamp).
- What was changed (original and new value).
As highlighted by AIFA the Italian Medicine Agency, only validated audit trails can guarantee the integrity and the regulatory usability of clinical data in healthcare and trials.
What is an audit in healthcare?
A healthcare audit is a systematic review aimed at verifying quality, safety, and compliance. In clinical trials, audits focus on adherence to GCP guidelines and approved protocols. The audit trail acts as the technical backbone, allowing auditors to trace every step of the data lifecycle.

Audit trail: a key requirement for data quality and compliance
Audit trails are not optional—they are mandatory. Regulatory authorities expect every EDC system to deliver complete, secure, and non-editable audit trails.
Key benefits:
- Data integrity – nothing is lost.
- Transparency – all changes are documented.
- GCP compliance – aligned with global standards.
Inspection readiness – faster and easier audit responses.
