Purpose
The purpose of this SOP is to define the requirements for audit trails and change control in
Scope
This SOP applies to all computerized systems used in clinical trials including Electronic Data Capture (EDC), Clinical Data Management Systems (CDMS), safety databases, and laboratory information systems. It covers generation, review, retention, and inspection of audit trails, as well as system change control procedures.
Responsibilities
- System Owner: Ensures audit trails are enabled, reviewed, and maintained.
- Data Manager: Reviews audit trails periodically for unauthorized or suspicious activity.
- IT Administrator: Implements and documents system changes under change control procedures.
- Sponsor/CRO: Provides oversight for audit trail reviews and change control compliance.
- QA Officer: Audits audit trail reports and verifies change control documentation during inspections.
Accountability
The sponsor and system owner are accountable for ensuring that audit trails are enabled and change controls are documented in compliance with regulatory requirements.
Procedure
1. Audit Trails
All electronic systems must generate audit trails capturing user ID, date, time, nature of change, and reason for change.
Audit trails must not overwrite original data and must be secure, time-stamped, and reviewable.
Review audit trails monthly and document findings in the Audit Trail Review Log (Annexure-1).
2. Change Control
All system changes must be documented in Change Control Form (Annexure-2).
Conduct impact assessment and determine validation requirements before implementing changes.
Obtain approval from QA and sponsor before implementing significant changes.
3. Review and Approval
Data Manager and QA must review audit trails and change control documentation.
PI and sponsor must approve changes impacting study data integrity.
4. Archiving
Archive audit trail reports and change control records in TMF for a minimum of 15 years or as per regulatory requirements.
