ALCOA+ is a fundamental concept in the pharmaceutical industry, particularly in
Good Documentation Practices (GDP) and data integrity. It provides a framework to
ensure that data generated during the manufacturing, testing, and quality control
processes is reliable.
The ALCOA principles were originally introduced by the U.S. Food and Drug
Administration (FDA) in the 1990s as part of its guidance on Good Manufacturing
Practices (GMP).
๐ – ๐๐๐๐ฟ๐ถ๐ฏ๐๐๐ฎ๐ฏ๐น๐ฒ: The data must be linked to the person who generated it. This includes
who performed an action and when it was performed.
๐ – ๐๐ฒ๐ด๐ถ๐ฏ๐น๐ฒ: Data should be clear and understandable, ensuring that it can be easily read
and interpreted by others. This is important for both handwritten and electronic records.
๐- ๐๐ผ๐ป๐๐ฒ๐บ๐ฝ๐ผ๐ฟ๐ฎ๐ป๐ฒ๐ผ๐๐: Data should be recorded at the time the activity is performed.
This ensures that information is captured in real-time, reducing the risk of errors or
omissions
๐ – ๐ข๐ฟ๐ถ๐ด๐ถ๐ป๐ฎ๐น: The data should be the first recording of the information. This means keeping
the original documents or electronic records rather than copies or transcriptions.
๐ – ๐๐ฐ๐ฐ๐๐ฟ๐ฎ๐๐ฒ: The data should be correct and free from errors. This requires verification
and validation to ensure that the data truly represents what occurred.
The “+” in ALCOA+ adds additional principles to further strengthen data integrity
๐ – ๐๐ผ๐บ๐ฝ๐น๐ฒ๐๐ฒ: All data, including any changes, deletions, or omissions, must be included.
This ensures that the entire history of the data is preserved.
๐ – ๐๐ผ๐ป๐๐ถ๐๐๐ฒ๐ป๐: Data should be consistent over time, including the application of correct
procedures, methods, and time stamps.
๐ – ๐๐ป๐ฑ๐๐ฟ๐ถ๐ป๐ด: Data should be preserved in a durable medium, ensuring that it remains
accessible and readable throughout its entire lifecycle.
๐ – ๐๐๐ฎ๐ถ๐น๐ฎ๐ฏ๐น๐ฒ: Data should be readily available for review and audit at any time. It ensures
that data can be accessed when needed for decision-making or inspections.
ALCOA++ with addition of ๐ง-๐ง๐ฟ๐ฎ๐ฐ๐ฒ๐ฎ๐ฏ๐ถ๐น๐ถ๐๐: Data should be traceable throughout the
process and life cycle, including changes.
