How do you handle OQ failures and corrective actions in pharma?

1 Identify the root cause

The first step after an OQ failure is to identify the root cause of the problem. This may involve reviewing the test protocol, the test results, the system configuration, the user requirements, and any other relevant documentation. You may also need to consult with the system vendor, the end users, or the subject matter experts to get more insight into the issue. The root cause analysis should be documented and approved by the appropriate stakeholders.

2 Implement the corrective action

The next step is to implement the corrective action that will resolve the OQ failure. Depending on the nature and severity of the problem, this may require modifying the system settings, fixing a bug, updating the software, changing the hardware, or revising the test protocol. The corrective action should be aligned with the user requirements and the system specifications, and should not introduce any new risks or errors. The corrective action should also be documented and approved by the appropriate stakeholders.

3 Re-test the system

The final step is to re-test the system to verify that the corrective action has successfully addressed the OQ failure. The re-test should follow the same test protocol as the original OQ, unless it has been revised as part of the corrective action. The re-test should cover all the test cases that failed in the original OQ, as well as any other test cases that may be affected by the corrective action. The re-test results should be recorded and approved by the appropriate stakeholders.

4 Follow the change control process

Throughout the process of handling OQ failures and corrective actions, you should follow the change control process that is established for your CSV project. The change control process ensures that any changes to the system or the validation documents are controlled, documented, reviewed, approved, and communicated to all the relevant parties. The change control process also helps to maintain the traceability and integrity of the validation evidence and records.

5 Avoid common pitfalls

Handling OQ failures and corrective actions can be a difficult and time-consuming process, particularly if they occur late in the validation lifecycle. To avoid common pitfalls, it is important to plan for potential OQ failures and corrective actions by conducting a comprehensive risk assessment and defining contingency plans. Additionally, clear and prompt communication with all stakeholders involved in the OQ process should be maintained. Furthermore, every decision and action related to OQ failures and corrective actions should be documented and justified, with a detailed audit trail of changes and approvals kept. Finally, the system should be tested and validated thoroughly before moving to the next phase of CSV, such as performance qualification or user acceptance testing. Although OQ failures and corrective actions are inevitable in CSV for pharma, these best practices and tips can help ensure that your system meets regulatory requirements and performs as expected under normal and abnormal conditions.
