How To Document A "Risk-Based" Rationale and Use It in A Resource-Constrained Environment

13-Jan-2025

With the highly regulated health industries in the pharmaceuticals, biotechnology, and medical devices sectors, GxP compliance, good practices, assurance of quality in the product, assurance of the safety of the patients, and data integrity have become even more critical. Computerized systems allow these objectives to be met, but they must be carefully verified and validated to minimize the risk and ensure proper working. In a resource-constrained environment, the adoption of a risk-based approach becomes a strategy for prioritizing critical areas, optimizing efforts, and ensuring compliance.

The need for a risk-based rationale

Its essence lies in taking the risk through proper assessment and documentation and then highlighting its criticality, followed by appropriate mitigation strategies. Such an approach becomes particularly important when resources in the form of time, budget, or even expertise are a limitation, making organizations able to focus them accordingly without compromising their compliance with regulation and operational efficiency.

Steps to Documenting a Risk-Based Rationale

Scope and Objectives
Define the scope of the computerized system and its intended use. Clearly articulate the objectives of the system, including its impact on GxP-critical elements like patient safety, product quality, and regulatory compliance.

Initial Risk Assessment
Risk Analysis Identify potential risks to the system: data integrity, functionality of the system, and continuity of operations. Categorize these risks into GxP impacts (patient safety, product quality, regulatory compliance) and non-GxP impacts (business continuity).

Write the rationale.
Prepare a risk-based approach document that includes the scope of the system, identified risks, their criticality, and why specific risks have been prioritized. This document provides a reference to stakeholders and auditors about meeting regulatory expectations.

Leverage verification and validation.
Verification and validation (V&V) are part of a risk-based rationale. Verification ensures that the system meets the predefined specifications, whereas validation is the process to ensure that it is fit for its intended use. Both are crucial for maintaining the integrity, accuracy, and reliability of computerized systems.

The V-model of system development in a resource-constrained environment provides an efficient framework. This model puts a lot of emphasis on the definition of system requirements and risks at the beginning stages and validating them at every subsequent stage. For instance, during the IQ phase, check that hardware and software are installed correctly. During the OQ, test the functionality of the system against operational requirements, and during the PQ, check whether the system meets its intended purpose under real-world conditions.

Best Practices for Risk-Based Verification and Validation

Emphasize High-Risk Areas
Assign validation to systems that are critical to patient safety, product quality, or data integrity. For instance, it is much more important to validate a quality management system rather than a training management system.

Increase Data Integrity Measures
Implement measures such as data audits and electronic signatures to maintain traceability and reliability. Data logs should be reviewed periodically for discrepancies or possible breaches.

Ensure Personnel Training
Human error is still one of the significant factors in system validation. The personnel should be given proper training on the functioning of the system, validation procedures, and regulatory requirements to reduce risks due to improper use.

Conduct Periodic Reviews
Regularly review and update the risk-based justification in light of changes in the system, regulation, or technology. As an example, AI integration within the systems creates the need to adjust the validation procedures to suit new challenges in place.

In a resource-constrained environment, the risk-based rationale ensures that compliance efforts are both effective and efficient. It helps the organizations to concentrate their limited resources in the critical areas for regulatory compliance and operational excellence. Verification and validation are still at the core of this approach and give assurance of the system's ability to fulfill its intended use while ensuring the safety of patients, product quality, and integrity of data.

Ultimately, an adequately documented risk-based rationale is the roadmap for the effective management of computerized systems, demonstrating regulatory compliance and risk mitigation with limited resources.
