How to Conduct Periodic Review of Computerized Systems / GxP Applications?

A regular audit of computerized systems and GxP applications is one of the foundations of pharmaceutical compliance, ensuring that the systems function as intended with the best quality and patient safety in mind. Validated systems in the modern pharma environment facilitate crucial processes, including clinical trials, production, and data analysis, and regulatory submissions.

Any compromise of data integrity, regulatory scrutiny, or product quality can result from a lapse in monitoring or review.

Regulatory authorities such as the FDA, EMA, and MHRA attach importance to the regular review as a continuous compliance measure. These reviews determine the fitness of computerized systems, determine risk, detect deviations, and ensure that the controls are operating effectively.

With the rise of digital technologies, automation, and cloud-based systems, it has never been more crucial to conduct an organized and regular review of processes. We are going to consider the whole lifecycle of a periodic review in this guide.

About Periodic Review

Periodic review is a systematic examination conducted over a specific period to ensure that computerized systems and GxP applications remain within regulatory, operating, and quality standards.

Compared to initial validation, which confirms that a system has been designed and implemented properly, periodic review focuses on sustained performance, compliance, and risk management.

Systems are to be continuously monitored according to regulatory frameworks throughout the globe, such as FDA 21 CFR Part 11, EMA Annex 11, ICH Q7, and GxP principles. The reviews assist organisations in identifying potential loopholes in controls, deviations, and vulnerabilities that might impact product quality or data integrity.

The key objectives of periodic review include:

• Ensuring that the functionality of the systems matches the intended use.
• The user access is in place, and so is the security control.
• Reconciling audit trail, system log, and change management records.
• Determining regions of risk or possible non-conformance.

Through periodic review, pharmaceutical firms can respond proactively to their risks, maintain their credibility in the regulatory environment, and avoid the costs of compliance, such as FDA Form 483 observations or EMA inspection results.

In the case of professionals, this process will help them master expertise in computerized systems validation, GxP compliance, and quality risk management, career opportunities in QA, CSV, and IT compliance.

Key Components of a Periodic Review of Computerized Systems/GxP Applications

A comprehensive review concerns not only system performance but also compliance, risk, and documentation.

System Functionality Assessment

The system should be maintained to ensure it can perform its intended functions. This incorporates the assessment of software modules, interfaces, and workflows. Any anomaly or failure could indicate a need for corrective measures.

User Access and Security Review

It is essential to ensure that user roles, permissions, and authentication procedures are not outdated and remain suitable to keep data confidential. Periodic audit helps to eliminate unauthorized access or misuse of sensitive GxP data.

Audit Trail Review and Change Management

The changes, patches, and updates made in the system are to be reviewed to ensure that they are well-documented and approved. Audit trails should be verified to be complete, accurate, and have integrity as required by the regulations.

Checks on Data Quality and Integrity

The data created, processed, and stored in the system should be accurate, complete, and retrievable. Periodic reviews determine whether the systems are still upholding ALCOA+ principles and free from data corruption.

Exception Handling and Review Deviation

All previously reported deviations, errors, and exceptions should be reconsidered to ensure that corrective and preventive actions (CAPAs) are effective. This guarantees that it is in constant compliance and prepared for inspection.

When these elements are addressed in every review, companies will develop a holistic compliance picture that reduces risks, enhances quality systems, and increases regulatory credibility.

Conducting a Periodic Review of Computerized Systems/GxP Applications
