Data Integrity Checklist for Pharmaceutical Industry

This checklist is not complete nor is it the purpose of an audit to ask all possible questions or review all aspects of a topic. The purpose of this article is to serve as a tool for identifying potential data integrity issues. It is not a standard. This article is not all-inclusive and is meant to be used in addition to standards/guidelines that address GMP/quality assurance topics during audits of facilities supplying materials to the pharmaceutical industry.

1	Data Governance Policy Is there one and are IT personnel familiar with its content Production, operations, QC lab personnel?
2	Is there a risk assessment for Data Governance of computerized systems
3	Does the risk assessment consider risks related to the IT department? Does it consider risks related to outsourced IT operations?
4	Is there a list of authorized IT service providers?
5	Have IT service providers been audited?  Review the most recent audit report and see if CAPA’s have been addressed.  Did the audit address data integrity/governance?

Is the audit trail enabled?
15	Are data collection audit trails reviewed? At what frequency and by whom? Are they attached to the results reviewed by QP at release?

16	Ask an analyst to print out a data audit trail.  Do they know how to do that?  Review it on the computer – are the users identified by name or as User 1, 2, 3 or are they all just “User”
17	Does the audit trail explain in human-readable form, what change was made and why?  If it describes the change but not the reason – ask the analyst, separately their manager, and separately the QP who released the batch – what the reasons are. In particular focus on deletions.

19	Are the user name and passwords program-specific or is a workstation accessed by entering a windows user name and password? NOTE: if yes, probably all users are entering a single user name and if a workstation has several programs installed, access to those programs is not controlled once the workstation is open.

3	Individual balances (used in product testing and release making decision): Have print out facility The print out captures: Balance id Date & Time
How is the data backed up?
1	Do SOPs exist on how data is backed up that includes how often and what happens if a failed backup occurs
2	Has the backup of data been tested?  What files are backed up? Does it include the metadata
3	Has a restore of the backup been verified and how often does this happen? Is it defined in an SOP?
4	Check Recycle bins for any files & folders related to analytical data

NOTES:

• When looking at security features ensure that the critical parameter changes are not performed by the person who approves or owns the data.
• When approving the data does the supervisor review the audit trail
• Control for accounts that can change critical parameters

1. Password expiration required
2. Account management required
3. Maintain a list of users with access to the password
4. Logout functionality (automatic Logoff or SOP enforcement)

There are two different types of audit trials that need to be considered:

System Configuration Audit Trail

• Tracks actions of System Administrator
• Tracks changes to “rules” for operating the system
• These types of audit trails should be reviewed as part of the system periodic review process.

Data Audit Trail

• Tracks actions of Users, Reviewers, Approvers
• Tracks changes to data
• These types of data audit trails shall be reviewed every time the data is being reviewed. Review needs to include data + meaningful metadata
