Triggers for Revalidation and Maintaining the Validated State

Maintaining a validated state is critical to ensure computer system validation in pharma adheres to continuous compliance principles. Various triggers initiate the need for revalidation, such as:

Major software updates
Changes in regulatory requirements
Hardware upgrades
Production process changes impacting system functionality

For example, when an organization upgrades a laboratory information management system (LIMS), it is imperative to assess how the upgrade impacts functionalities previously validated. Should a significant change occur that could affect data integrity or operations, a formal revalidation process must be initiated to ensure ongoing compliance.

Documentation should demonstrate the rationale for these revalidation triggers alongside a well-developed revalidation plan, which includes methodologies, impacted components, and acceptance criteria.

Impact Assessment of Protocol Deviations

Notably, protocol deviations are situations when the execution of a validation protocol does not adhere strictly to established standards. When these deviations occur, organizations must perform an impact assessment that evaluates the consequences of the deviation on the validated state. Each protocol deviation must be documented, assessed for its potential influence on data integrity, whereas any resultant risks must be communicated effectively to relevant stakeholders.

For instance, a deviation involving the omission of a required test during PQ could undermine the validity of the entire validation effort. Therefore, the impact assessment must cross-examine:

The criticality of the omitted test
The context around the reason for the deviation
The potential risk posed to product quality

Providing a robust impact assessment that qualifies the current state of validation in light of these deviations can be instrumental in presenting findings to regulatory bodies.
