Auditing GxP Computer Systems for Regulatory Compliance

Integrate EU annex 11 and US 21 CFR part 11 into an audit questionnaire covering risk management, personnel, supplier, data integrity, audit trail, and electronic signature to assess compliance.

Apply risk management across the life cycle of computerized systems, addressing validation, maintenance, and change control, protecting patient safety, data integrity, and product quality under annex 11 and part 11.

Understand how supplier category, SLAs and organization level agreements, risk assessment, and supplier audits ensure regulated vendors meet user requirements and align quality system documentation with validation reports.

Explore validation under 21 CFR part 11 and a risk-based life cycle. Confirm life cycle documentation, change control, user requirements, traceability, supplier assessment, and data migration integrity.

Ensure data integrity by generating accurate, complete records in both human-readable and electronic forms for inspection and copying. Integrate data flow and terminal checks to ensure authenticity and integrity.

Audit focus on data storage under GxP compliance: protect data from physical and electronic damage, ensure accessibility, readability, and accuracy during the retention period, validate backups and restore capabilities.

Evaluate how printouts from electronic records support batch release by showing clear copies and indicating data changes since original entry, aligning EU and FDA GxP requirements.

Audit trails justify all GNP changes or deletions built into system risk assessment, enable periodic reviews, avoid obscuring data, retain time-stamped records with time zone, and allow review or copying.

Learn how change and configuration management controls system changes through defined procedures, verify configuration before reuse, and perform periodic evaluations and reviews to ensure GMP compliance and a validated state.

Limit access to regulatory GXP computer systems to authorized individuals through physical or logical controls, logins, and access cards; maintain audit trails of authorizations and actions to preserve data integrity.

Report and assess all incidents, not only system failures or data errors, including those not related to computer systems, to identify root causes for corrective and preventive actions.

Evaluate electronic signatures under 21 CFR part 11, ensuring time-stamped, permanently linked electronic records, and enforce identity verification with two-factor or biometric controls.

Ensure only qualified personnel certify batch release and record who signs off on the GxP computer system; establish business continuity with documented backup plans, manual steps, and 24-hour SLA support.

Assess archiving processes to ensure data remains accessible, readable, and intact through retirement and migration, while enforcing system documentation controls and revision and change control procedures to maintain audit trail.

Analyze how to prepare an audit report for GxP computer systems, covering management summary, observations on data integrity, and compliance with 21 CFR part 11 and EU annex 11.
