Transparency has emerged as a key player in today’s digital landscape, particularly within the realm of product supply chains. In an era where consumers are increasingly conscientious about the origins and processes behind the products they use, understanding the pathways of goods throughout the supply chain has become paramount. This heightened awareness among consumers has underscored the significance of traceability, ushering better means to equip stakeholders with the ability to trace and track the journey of products from their inception to the hands of the end-user.

Even though the digital revolution was initiated by the invention of the computer in the mid-20th century, the era of digitalization didn’t pick up pace on a global level until the 1980s. The U.S. Food and Drug Administration (FDA) established guidelines for Electronic Records in 1997 by introducing the 21 CFR Part 11 regulation, which presented the specific compliance requirements for digital documentation systems.

Adherence to this regulation necessitates assigning a digital signature to a specific individual, specifying the signature type (such as review, approval, or authorship), and ensuring traceability from the document back to the signer through secure electronic signatures, access controls, and audit trails, fostering accountability throughout the product lifecycle. By complying with the 21 CFR Part 11 regulation, businesses can instill confidence in consumers, regulatory bodies, and stakeholders alike.

In the continuously progressing landscape of tech-enabled quality and risk management, accessing an audit log, preferably in real-time, has become an integral aspect of an organization’s daily operations.

By examining audit logs and interconnected audit trails, administrators of systems can monitor user actions, and validate compliance to regulatory standards. This process allows for a thorough understanding of a system’s operational dynamics, contributing to both proactive management and reactive responses to quality and safety incidents.

A Glimpse into 21 CFR Part 11 Regulation’s Audit Trail Requirements

It was in 1997, that the 21 CFR Part 11 regulation was introduced, affirming the equivalence of electronic records and signatures, meant for regulatory compliance, to their paper and handwritten counterparts. This regulation extends approval for the adoption of electronic record-keeping systems in the maintenance of records and the submission of information to regulatory authorities. These rules are applicable to FDA-regulated industries using electronic records and electronic signatures.

While 21 CFR Part 11 does not replace existing FDA regulations, it builds upon FDA predicate rules, ensuring companies using digital systems adhere to compliance-related processes. Adherence to core FDA Predicate rule principles remains vital for understanding and implementing 21 CFR Part 11 controls relevant to regulated products.

Here’s a quick summary of specific audit trail requirements according to FDA’s 21 CFR Part 11:

As per this regulation, every electronically stored record must possess a computer-generated, time-stamped audit trail to ensure traceability. Audit trails play a crucial role in meeting the compliance requirements outlined in 21 CFR Part 11, providing a comprehensive record of all activities within a computer system.

The FDA definition for audit trails used in computerized systems is as follows:

“An audit trail is a secure, computer-generated, time-stamped electronic record that facilitates the reconstruction of events related to the creation, modification, and deletion of an electronic record.”

The 21 CFR Part 11 Subpart B Sec. 11.10 Controls for Closed Systems elaborates that persons who use closed systems to create, modify, maintain, or transmit electronic records shall employ procedures and controls designed to ensure the authenticity, integrity, and, when appropriate, the confidentiality of electronic records. It also emphasizes the use of secure, computer-generated, time-stamped audit trails to independently record the date and time of operator entries and actions that create, modify, or delete electronic records. These audit trails are mandated to meet the following requirements:

1. Audit Trail Security: Authorized individuals must exclusively have access to the system, allowing them to make changes and sign off documents. This guarantees the audit trail’s security, aligning with 21 CFR 11.10(e). Restricting access to authorized personnel, as specified in 21 CFR 11.10(d), is essential for maintaining the integrity of the audit trail.

2. Automated Time-Stamping: Adhering to 21 CFR 11.10(e), the system should automatically document the time and date of electronic record actions, including creation, modification, document approval, retirement events, etc.

3. User Identity Verification: Recording the user’s identity for actions performed within the system is imperative, aligning with 21 CFR 11.10(g). Authority checks must be in place to ensure that only authorized individuals can utilize the system.

4. Action Tracking: As stipulated in 21 CFR 11.10(e), the audit trail should comprehensively capture and record all actions and changes made to electronic records. It should also facilitate easy comparison of document versions and seamless restoration of previous versions when necessary.

5. Version History: The audit trail must not hide or overwrite previously recorded information, ensuring a complete and unaltered record of actions with proper version history for all changes made.

6. Audit Trail Retention: Compliance requires the audit trail to be stored for a duration appropriate to the record’s content and purpose. Regular data backups and disaster recovery plans further safeguard against data loss in unforeseen events.

7. Accessibility: The audit trail should be readily accessible for review and copying during inspections. Organizations may also streamline the process by creating document collections with relevant records for upcoming audits.

Anatomy of Audit Log

Definition

An audit log is a chronologically ordered record, marked with date and time, that captures the history and specifics of various activities such as transactions, work events, product development stages, control executions, or entries in financial ledgers. It serves to document a sequence of events related to virtually any type of work process, whether executed manually or automatically.

Types of Activities Recorded

Audit logs serve as a valuable resource for demonstrating ongoing compliance during inspections and audits and can be employed to capture a wide array of activities and events, such as:

• User logins and logouts: Recording when users log in or out of a system provides a foundation for tracking user activities and ensuring secure access. User activity, including actions like logins, logouts, and any user-initiated operations within the system, can be monitored.
• Access control: Details about who accessed specific files or databases, when, and what actions were performed (read, write, modify) are critical for compliance activities. Access control is maintained by the audit log, which tracks modifications to access rights and permissions.
• Document revisions and approvals: Tracking changes made to relevant documents, including revisions, edits, and approvals can be carried out with an audit log. It can also serve to record the details of individuals who initiated document changes and those who approved them.
• System configurations: Changes to system configurations, settings, or permissions are logged to monitor alterations that might impact the stability and security of the system. System events can also be documented in the audit log, offering insights into system functionality, execution of operations, and identifying potential performance issues.
• Supplier and vendor interactions: Systematically monitor and record all engagements with suppliers and vendors to maintain a detailed log of any modifications made to supplier agreements, contracts, or quality requirements, enabling effective oversight and documentation of the evolving relationships and terms.
• Non-conformance reporting: Capturing information on quality events, incidents, and non-conformances can be executed effectively with audit logs by documenting any deviations or issues, and the actions taken to address and rectify non-conformities.
