Data Integrity: Ensuring GxP-compliant Data Integrity
Data integrity is a central quality criterion in the GMP-regulated environment. Raw data and metadata must be captured simultaneously, completely, and precisely, with traceability to the origin being ensured. Data management requires tamper-proof storage while maintaining data availability throughout the entire retention period. Changes must be traceable through version control without compromising original entries. Data authenticity is ensured through access controls, electronic signatures, and user management. These requirements apply across systems for both paper-based and computer-supported systems and are fundamental to GMP compliance.

Implementation of ALCOA+ Principles
- A – Attributable (Assignable): Person, time, and action assignable during data collection.
- L – Legible (Readable): Records permanently readable and accessible to authorized personel.
- C – Contemporaneous (Timely): Documentation immediately upon activity execution.
- O – Original (Original): Data in original form or as verified copy, changes traceable.
- A – Accurate (Accurate): Data precise, error-free, and corresponding to actual observations.
- Additional Requirements:
- Complete
- Consistent
- Enduring
- Available
FAQ – Data Integrity in GxP Environments
Data integrity means that GxP data must be complete, consistent, and accurate (correct) throughout the entire data lifecycle. This ensures the reliability and trustworthiness of data for regulatory decisions and patient safety.
The fundamental principles are often summarized under the acronym ALCOA+:
- Attributable: Who created the data and when?
- Legible: Are the data permanently readable and understandable?
- Contemporaneous: Were the data recorded at the time of the activity?
- Original: Is it the original data or a certified copy („True Copy“)?
- Accurate: Are the data error-free?
+ (Additional points such as Complete, Consistent, Enduring, Available).
Data integrity is critical because GxP data forms the basis for decisions regarding the quality, safety, and efficacy of products (e.g., pharmaceuticals). Lack of integrity can lead to erroneous batch releases, incorrect study results, and ultimately to patient endangerment as well as regulatory actions (e.g., Warning Letters, production shutdowns).
The data lifecycle encompasses all phases from data generation, through processing, storage, and archiving, to data destruction. Data integrity must be ensured in every phase of this cycle to guarantee complete traceability.
Audit trails are an essential control instrument. They automatically capture who, when, and what was changed in an electronic record (creation, modification, deletion). They must be activated, secured, and regularly reviewed to prevent manipulation or unauthorized changes.
For paper documents, data integrity is ensured through compliance with Good Documentation Practice (GDP). This includes: signature and date for every entry, documented corrections (single line, signature, date), no use of pencil or correction fluid, as well as the review and approval of all relevant documents and records.
A Data Governance system establishes the organizational structure, roles, responsibilities, and processes to manage and maintain data integrity throughout the entire lifecycle. Among other things, it defines the handling of raw data, metadata, audit trails, and the accountabilities for data quality.
Yes, all computerized systems that generate, store, or process GxP-relevant data must be validated based on risk. Computer System Validation (CSV) ensures that the system consistently and correctly fulfills its intended purpose and that data integrity requirements, such as access controls and audit trails, are implemented.
Common vulnerabilities include:
- Uncontrolled data access (e.g., shared passwords).
- Missing or ineffective audit trail review.
- Incorrect system configuration (e.g., time and date).
- Incomplete raw data (e.g., deletion of „bad runs“ without justification).
Personnel play a central role. All employees who generate, process, or review GxP data must be adequately trained and understand the importance of data integrity. The company must foster a culture of quality and data integrity in which every employee takes responsibility for data quality.
