Archiving and retrieval systems ensure that GxP records are preserved for their required retention periods and can be accessed promptly when needed. Regulatory authorities require that archived records remain complete, legible, and readily retrievable throughout the retention period. Effective archiving protects records from deterioration, loss, or unauthorized alteration.
What Are Archiving and Retrieval Practices?
Archiving is the process of storing records that are no longer in active use in a secure environment that preserves their integrity. Retrieval is the ability to locate and access archived records within a reasonable timeframe when requested for regulatory inspection, audit, or investigation. Archives may be physical (off-site storage facilities) or electronic (tamper-proof storage systems with redundant backups).
Principles
Archived records must be protected against damage from fire, water, pests, and environmental factors, with access restricted to authorized personnel. The ALCOA+ attribute of enduring availability requires that records remain legible and accessible for the full retention period. For electronic records, this includes maintaining the hardware and software needed to read the data or migrating data to current formats.
Best Practices
Establish a documented archiving schedule that transfers records to secure storage promptly after the active use period ends. Create a searchable index or inventory of all archived records, and test retrieval capabilities periodically to ensure they function as expected. Integrate archiving procedures with document numbering and version control systems to simplify location and cross-referencing of historical documents.
Regulatory Requirements
21 CFR Part 211.180 requires that records be retained for at least one year after the expiry date of the batch or one year after release, with some records retained longer. EU GMP Chapter 4 specifies that archived records should be protected against deterioration and loss. ICH Q7 requires that records be retained for at least one year after the expiry date of the batch and that archives be stored in a separate and secure location.
Conclusion
Proper archiving and retrieval practices are essential for maintaining the integrity and availability of GxP records over time. Organizations must invest in appropriate storage infrastructure and regularly verify that archived records can be accessed when needed. A well-managed archive supports efficient regulatory inspections and protects the organization in the event of product complaints or litigation.
