Types of Medical Devices QMS Audit: Compliance and Process Improvement

Medical Devices Quality Management System Audit Types

Quality Management System for Medical Devices (QMS)

Quality Management System (QMS) is a structure developed to control, monitor and improve all processes and activities of an organization in terms of quality. Medical device manufacturers generally establish a QMS in accordance with the ISO 13485 standard. This system covers all processes from the design of the devices to the production stages, from packaging to distribution, and quality control is ensured at every step.

ISO 13485 is the most widely used international standard for quality management of medical devices and provides manufacturers with the following requirements

• Legal compliance: Products must comply with legal requirements.
• Improvement of internal processes: Improving the efficiency of production processes.
• Documentation and traceability: Accurate recording and tracing of all product-related processes.
• Risk management: Minimizing the health impacts of medical devices.

Types of Audits for Medical Devices

Various types of audits are used in quality management system audits for medical devices. These audits aim to assess the effectiveness of production processes, products and QMS. The main types of audits are as follows:

a. Internal Audits

Internal audits are audits carried out by the manufacturer within its own organization. These audits are conducted to assess and improve the effectiveness of the quality management system. The purpose of internal audits is to determine how well the organization is achieving its quality objectives and to identify any non-compliance or areas for improvement. Internal audits are usually performed in the following areas:

• Processes: Evaluation of production, design and distribution processes.
• Certification: Compliance with ISO 13485 and other quality management standards.
• Risk management: Review of measures taken to ensure the safety of devices.
• Documentation control: Assessing whether product-related records are kept accurately and completely.

Internal audits are a critical tool for identifying system weaknesses and addressing deficiencies in processes.

b. External Audits

External audits are audits performed by an independent third party, usually an accreditation body or regulator. They are conducted to verify that medical device manufacturers comply with certain quality standards and regulations. Compliance with standards such asISO 13485, compliance with local and international regulations such as FDA (Food and Drug Administration) or MDD (Medical Device Directive) is audited. The main objectives of external audits are:

• Legal compliance: To verify the manufacturer's compliance with local and international regulations.
• Adequacy of quality systems: To assess the effectiveness of the QMS.
• Risk assessment: Managing potential risks.

Such audits are usually more in-depth and can have serious consequences in the event of a specific non-compliance.

c. Product Audits

Product audits are audits that assess whether a specific medical device meets quality and safety criteria, either during or after production. Product audits are performed for the following purposes:

• Product specifications: Whether the product conforms to design specifications.
• Legal regulations: Compliance of the device with health and safety standards.
• Feedback and traceability: Improvement of the product based on user feedback.

These audits are essential to reduce the potential health risks of devices and to ensure the safety of each device.

d. Process Audits

Process audits are audits performed at every stage of the production processes of medical devices. These audits determine whether the production processes comply with certain quality standards and measure the effectiveness of the processes. The aim of process audits is to reduce the risks arising from production errors and to improve processes. Such audits can be performed in the following areas:

• Production lines: Whether each step in the production process is working correctly.
• Design and development: Quality control during the design and development of new products.
• Inventory and procurement: Procurement and inventory management of medical device components.

Process audits help prevent systematic errors and improve production efficiency.

e. Recall and Field Audits

Recall and field audits are audits conducted specifically when a defect or problem is detected in products. These inspections monitor how the device performs in the market and gather information for recall, repair or remediation. Recalls are crucial to prevent potential health risks. These types of inspections:

• Devices at risk: Assesses the potential harm of devices on patients.
• Recalls: Determines the recall and safety measures for problematic products in the market.

Compliance and Process Improvement Strategies

Audits not only ensure legal compliance, but also encourage continuous process improvement. Process improvement is a continuous effort to increase the effectiveness of quality management systems, reduce error rates and optimize production efficiency. Process improvement strategies may include:

a. Continuous Training and Awareness

Employees need to be trained on deficiencies or areas for improvement identified during audits. Continuous training increases the effectiveness of the quality management system.

b. Error Analysis and Corrective Actions

Errors occurring in products or processes should be examined by conducting root cause analyses. Afterwards, corrective and preventive actions are taken to prevent recurrence.

c. Performance Monitoring and Reporting

Monitoring performance after audits and reporting on specific quality indicators is an important way to assess the success of the improvement process.

d. Technological Investments

Leveraging new technologies to produce high-quality medical devices can help improve processes. Technologies such as automation, data analytics and artificial intelligence contribute to speeding up production processes and reducing errors.
