Audit Trail Definition as per FDA
According to the FDA’s guidance for industry on computerized systems used in clinical trials, an audit trail is defined as:
“A secure, computer-generated, time-stamped electronic record that allows reconstruction of the course of events relating to the creation, modification, and deletion of an electronic record.”
In other words, an audit trail is the history of all actions performed in a document, including the responsible person for the action, when, which action was taken, and any other relevant details.
Audit trails enable tracking the document time-sequence development to ensure they have not been altered in any way that would compromise accuracy or reliability.
What are 21 CFR Part 11 Audit Trail Requirements?
The 21 CFR Part 11 regulation requires the system used to manage electronic records to provide a secure, computer-generated, and time-stamped audit trail.
Its purpose is to accurately record changes made to documents.
Below, we will cover the audit trail requirements outlined in 21 CFR Part 11 section 11.10 and provide a few brief examples of how solutions like SimplerQMS can help companies meet them.
Please note that the information presented in this article is for educational purposes only and is not intended to be used as official regulatory guidance. It is recommended that companies seeking compliance with 21 CFR Part 11 refer to the regulation.
Ensure Audit Trail Security
Only authorized individuals must have access to the system and be able to make changes and sign off documents. This ensures that the audit trail is a secure and trustworthy record of actions.
According to 21 CFR 11.10(e), audit trails must be secure.
To achieve security, the system should limit access to only authorized individuals, as stated in 21 CFR 11.10(d).
Enabling access, the ability to make changes, and document sign-offs only by authorized individuals ensure a secure and trustworthy audit trail of actions.
For example, SimplerQMS meets these security requirements using Microsoft Azure Active Directory for controlling user access within the system, ensuring secure authentication and authorization.
Implement Computer-Generated Audit Trail
As outlined in 21 CFR 11.10(e), an audit trail must be automatically generated by the system and not manually created to eliminate human errors.
For instance, solutions like SimplerQMS, by default, automatically generate and store every version of a document, file, and record.
As per section 21 CFR 11.10(e), the audit trail must document the time and date of actions performed in the electronic record, including:
- Creation events
- Modification events
- Document approval events
- Retirement events
The system should also provide the ability to choose the system’s standard time zone, including UTC, as the FDA recommends.
Verify User Identity
The audit trail must record the user’s identity who performed actions inside the system.
According to 21 CFR 11.10(g), authority checks must be in place to ensure that only authorized individuals can use the system.
To give an example, user identity is automatically recorded in SimplerQMS keeping track of who created, reviewed, approved, updated, and retired documents.
Track Performed Actions
As outlined in 21 CFR 11.10(e), the audit trail must capture and record all performed actions and changes made to the electronic records.
For example, in SimplerQMS, every time a document is edited, reviewed, approved, or retired, the system automatically records and stores all the relevant data. Including user identity (who performed the action), date and time of changes, and type of change made to the document.
The audit trail also lists all versions of documents and provides a simple way to compare them as well as restore any of the previous versions if needed.
Preserve Previously Recorded Information
As stated in 21 CFR 11.10(e), the audit trail must not hide or overwrite previously recorded information.
In a solution such as SimplerQMS, all records have a complete version history and it is not possible to delete electronic records. They can only be archived or retired.
Retain Audit Trail Documentation
As per 21 CFR 11.10(e), the audit trail must be stored for a period that is appropriate for the record based on its content and purpose.
In SimplerQMS, for example, audit trail data can be stored and retained for as long as required by the user. All records are securely stored in the cloud and can be accessed anytime with full control over who has access to them.
Regular data backups and disaster recovery plans also ensure that no data is lost in case of any unforeseen events.
Ensure Audit Trail Availability for FDA Inspection
According to 21 CFR 11.10(e), the audit trail should be easily accessible for review and copying by the FDA during an inspection.
For instance, SimplerQMS allows you to easily view the history of any record, as well as copying or exporting of system records and data for inspection purposes.
You can also create document collections with relevant records for upcoming audits.
It is important to note that this article only covers the audit trail requirements outlined in 21 CFR Part 11. However, there are many other requirements outlined in this regulation that must be met to ensure compliance.

Components of an Audit Trail Entry
When it comes to audit trail entries, several components are included.
Here is an example of what an audit trail entry in SimplerQMS looks like when viewing document history:
- Name: The title or label that is used to identify the document.
- Version: Unique identifier that is assigned to each saved version of a document or file within a system.
- User: The system records the identification code or name that identifies the person who altered the document.
- State: A document’s state refers to its current status within a specific workflow.
Key Audit Trail System Features
An effective audit trail system must capture accurate and comprehensive data. It helps maintain a history of all actions and changes made to their electronic records.
Some key features of audit trail systems include:
- User Access Control: The system should limit user access to only authorized individuals. Companies must also perform periodic authority checks to ensure access control.
- Electronic Signatures: The system should allow users to digitally sign off and approve documents, providing a secure and traceable method of releasing documents.
- Time-Stamping: The system should record the exact time and date of each event or change to the document in a time-stamped, computer-generated audit trail.
- Version History and Traceability: The system should be able to track changes to a document or file over time, provide the ability to restore previous versions if needed, and offer traceability by showing who made the changes, when, and why.
- Data Integrity: The system should ensure the integrity of the data by using secure data storage, access controls, and encryption to prevent unauthorized alteration.
- Retention and Archiving: The system should allow companies to retain and archive audit trails for the same period required for the related electronic record.
- Synchronized Clock System: The system should maintain consistent time across multiple devices, ensuring that all events are accurately time-stamped and logged.
Benefits of Implementing the Recording of Audit Trails
Implementing the recording of an audit trail offers several benefits to companies in regulated industries, such as pharmaceuticals, medical devices, and biotechnology.
These benefits include:
- Ensuring data integrity and accuracy: Audit trails provide a detailed record of all system actions, including when changes were made, who made them, and why. This helps to maintain the authenticity and integrity of electronic records.
