risk assessment is essential. This risk assessment should utilize tools such as Failure Mode and Effects Analysis (FMEA) or Hazard Analysis and Critical Control Points (HACCP) to identify potential risks associated with the equipment operation and the sterilisation process. The risk assessment should evaluate the impact and likelihood of each risk and establish control measures to mitigate these risks, ensuring compliance with ICH Q9 principles.

• Gather input from all relevant stakeholders – Include operators, QA, and regulatory personnel.
• Define operational requirements – Clearly specify the functions the equipment must perform.
• Conduct qualitative or quantitative risk assessments – Utilize FMEA for identifying potential risks.
• Document justification for selected design and operational parameters – Ensure it aligns with regulatory expectations.

The URS and risk assessment documents must be maintained and updated throughout the equipment lifecycle to reflect any changes in requirements or additional insights. Regulatory authorities may review these documents to ascertain that appropriate definitions of risk mitigation strategies are in place, potentially referencing official guidelines from WHO and PIC/S.

Step 2: Protocol Design and Approval

Following the completion of the URS and assessment of risks, the next phase is the creation of the Equipment Qualification Protocol (EQP). The EQP serves as the foundational document that outlines all qualification activities, acceptance criteria, and the rationale behind the chosen validation approaches.

The protocol should begin with an introduction, stating the purpose and significance of the qualification process and referencing pertinent regulations such as ICH Q8, Q9, and Q10. Clearly define the scope of the validation, including any specific categories of sterilisation that will be assessed during the validation rounds (e.g., steam sterilisation, ethylene oxide sterilisation).

Specific sections of the EQP protocol should include:

• Equipment Description – Provide detailed specifications of the equipment including model, serial number, and manufacturer information.
• Qualification Strategy – Outline the qualification phases: Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).
• Test Methods and Acceptance Criteria – Clearly define how the performance of the equipment will be measured against the requirements established in the URS.
• Document Control – Detail how the protocol will be maintained and controlled throughout its lifecycle.

Each section must be comprehensive, as the protocol will undergo review and approval by multiple stakeholders within the organisation. Once vetted, the EQP must be signed off by senior management, ensuring a commitment to the validation process and adherence to compliance with regulatory expectations.

Step 3: Installation Qualification (IQ) and Operational Qualification (OQ)

After the protocol is approved, the focus shifts to conducting the Installation Qualification (IQ) and Operational Qualification (OQ). These components verify that the equipment has been installed correctly and operates according to predefined specifications outlined in the protocol.

The IQ involves checking that the equipment is installed according to its design specifications, including verifying utilities, equipment connections, and environmental conditions. Documentation associated with this phase should include:

• Installation Checklist – Confirm all components are correctly installed.
• Calibration Certificates – Present evidence of equipment calibration against established standards.
• Utility Confirmation Documents – Validate that necessary utilities such as electrical and water supplies meet required specifications.

Once the IQ is validated, the OQ phase can begin. The purpose of OQ is to ensure that the equipment operates reliably within its intended operating parameters. Key activities during the OQ phase should include:

• Functionality Tests – Execute tests to confirm the equipment performs necessary functions.
• Control System Checks – Validate alarms, fail-safes, and interlocks to ascertain appropriate operational safeguards.
• Verification of Calibration – It is imperative to ensure that the internal controls of the equipment are functioning correctly.

Documentation from both IQ and OQ needs to be exhaustive and precise. Each step must be recorded, including the results of tests and any deviations encountered. Such documentation will serve as evidence of validation efforts and is crucial during regulatory audits.

Step 4: Performance Qualification (PQ)

Once the IQ and OQ phases are successfully completed, the Performance Qualification (PQ) phase begins. PQ validates that the equipment operates correctly under simulated or actual production conditions and meets quality specifications over an extended period.

The PQ generally encompasses designing a validation study based on the critical parameters identified via the URS and risk assessment. The aim is to establish quantitative acceptance criteria based on historical data, scientific rationale, or predetermined industry standards.

Key components of the PQ phase include:

• Defining Critical Process Parameters (CPP) – Identify essential parameters that must be controlled to ensure process consistency and product quality.
• Sample Size and Statistical Analysis – Determine an adequate number of trials and statistical methodologies for analysis, ensuring compliance with ICH Q2 guidelines.
• Long-Term Studies – Consider running long-duration tests to collect data over time to confirm consistent performance.
• Documentation of Results – Record all results meticulously including any deviations or unexpected results and the corresponding investigations performed.

Upon completion, results should provide confidence that the equipment consistently performs as intended when subjected to normal operating conditions. The final report summarizing the PQ must detail the findings and confirm compliance with both internal specifications and external regulatory requirements.

Step 5: Continued Process Verification (CPV)

With successful performance qualification, the focus must shift toward Continued Process Verification (CPV). CPV is an ongoing verification process designed to monitor and evaluate the performance of the equipment and the sterilisation process over time. This phase is vital for ensuring continuous compliance with defined specifications and operational integrity.

Establishing an effective CPV strategy involves defining key performance indicators (KPIs) for the equipment and specifying monitoring methods, which may include:

• Real-time Monitoring Systems – Implement systems capable of monitoring for deviations in real-time, allowing for immediate corrective actions.
• Regular Review of Process Data – Schedule routine evaluations of process data to ensure equipment operates within established limits.
• Trend Analysis – Utilize statistical process control (SPC) charts to analyze performance trends over time.
• Audit and Review Strategy – Develop a systematic approach for internal audits and reviews to glean insights into operational effectiveness.

Documenting CPV activities is crucial for providing evidence of ongoing compliance. Detailed records should reflect observations, metrics, and investigations of deviations that may arise during normal operations. These records will support continuous quality improvement initiatives and serve as an important part of regulatory submissions.

Step 6: Revalidation and Change Control

The final step in the validation lifecycle involves establishing a robust Revalidation and Change Control program. Revalidation is essential as it ensures that any modifications to procedures, equipment, or processes do not negatively impact product quality or operational performance.

Strategies for revalidation should encompass:

• Schedule for Revalidation – Define intervals or triggers that necessitate revalidation, such as equipment modifications, technological upgrades, or significant changes in the process. Compliance with continual monitoring services may identify the need more promptly.
• Change Control Process – A documented change control procedure must be in place to assess the impact of changes and define required validation activities. Reference ICH Q10 for ensuring that change management principles are appropriately integrated.
• Documentation of Changes – Maintain detailed records of changes and the rationale for decisions made, preserving transparency and traceability.

When changes are made, especially concerning equipment alteration or process modifications, performing a gap analysis and revisiting the URS for potential updates will ensure alignment with both operational expectations and regulatory compliance.

Documenting the entire revalidation process, including findings from any assessments, is crucial for demonstrating compliance to regulatory authorities both during routine inspections and for routine educational purposes.
