Yes, medical devices in China are subject to regular reviews as part of the regulatory framework managed by the National Medical Products Administration (NMPA). These reviews are an essential component of ensuring that medical devices continue to meet safety, efficacy, and quality standards throughout their lifecycle. Below are the key aspects of the review and monitoring process for medical devices in China:

1. Post-Market Surveillance (PMS) and Ongoing Compliance

Once a medical device is approved and registered with the NMPA, manufacturers are required to engage in post-market surveillance (PMS). This ongoing process ensures that the device remains safe and effective in the market after it has been released. While the review is not as formal as the initial registration process, it is a crucial part of maintaining registration and ensuring compliance with regulations.

Key post-market obligations include:

• Adverse Event Reporting: Manufacturers must report any adverse events or incidents that occur during the use of the medical device. This is an essential part of the surveillance process and ensures that any potential risks associated with the device are addressed.
• Periodic Safety Update Reports (PSURs): For high-risk medical devices (Class II and III), manufacturers may be required to submit periodic safety update reports that detail the device's performance in the market, including any new risks or safety concerns identified post-launch. These reports are submitted to the NMPA to help assess ongoing safety and effectiveness.
• Recalls and Corrective Actions: If post-market surveillance reveals serious issues with a device (such as safety concerns or manufacturing defects), the manufacturer must initiate corrective actions, which may include product recalls or changes to the device’s labeling or instructions for use.

2. Periodic Registration Renewal

For certain devices, especially those in higher-risk categories (Class II and III), the registration certificate issued by the NMPA may be valid for a limited period, typically 5 years. After this period, the device may need to undergo a re-registration process, which includes a review to ensure that the device continues to meet the regulatory standards and is compliant with the latest requirements.

This review process may involve:

• Reevaluation of Product Performance: Manufacturers must submit updated data on the product's performance, including clinical data or other evidence that supports the device’s continued safety and effectiveness.
• Review of Compliance with New Regulations: If there have been updates to the regulations or standards (for example, changes in the China GMP (Good Manufacturing Practice) requirements or new safety standards), the NMPA may review whether the device complies with these updated standards.
• Facility Inspections: The NMPA may carry out inspections of the manufacturing facilities to verify compliance with Good Manufacturing Practices (GMP) and other regulatory requirements.

3. Regulatory Changes and Updates

China’s medical device regulatory environment is evolving, with frequent updates to regulations, standards, and guidelines. Manufacturers are responsible for ensuring that their devices comply with any new or revised regulations, even after initial approval. This means they must regularly monitor changes in:

• Product Classification: Regulatory shifts could result in a device being reclassified (for example, from Class II to Class III), which would require more stringent regulatory oversight and additional reviews.
• Technical Standards: Updates to technical standards for performance, safety, or quality could necessitate revisions to the device or its documentation to remain in compliance.
• Cybersecurity and Data Protection: For devices with software or digital components, adherence to the China Cybersecurity Law and Personal Information Protection Law (PIPL) may be required, with regular updates to ensure compliance.

4. Inspection of Manufacturing and Supply Chain Compliance

The NMPA may periodically inspect manufacturing facilities to ensure compliance with local GMP and Quality Management System (QMS) regulations. This is especially true if the device’s registration certificate is up for renewal or if there have been significant changes in the manufacturing process or location.

During these inspections, the NMPA will assess:

• Quality Control Systems: Whether the manufacturing processes continue to meet the quality standards set forth in the original registration.
• Supply Chain Management: Ensuring that the raw materials, components, and final products meet the required specifications and standards.

5. Changes in Manufacturer or Device Information

If there are significant changes to the manufacturer’s business (such as a change in ownership, address, or manufacturing site), or if there are major modifications to the device itself (such as changes to its design, intended use, or production process), the NMPA may require a supplementary submission or re-registration to evaluate whether the changes impact the device’s safety, performance, or regulatory status.

Examples of changes that would trigger a review include:

• Changes in the manufacturer (e.g., a change of company name or ownership).
• Modifications to the device design, indications for use, or the intended patient population.
• Updates to the clinical data or performance testing results.
• Introduction of new components or materials in the device.

6. Periodic Monitoring of Market Conditions

The NMPA is responsible for ensuring that medical devices meet regulatory requirements over time. As part of their surveillance, they conduct periodic market monitoring to detect any non-compliance issues. This monitoring includes:

• Post-market inspections of the devices available on the market to check for safety issues, product defects, or non-compliance with regulatory standards.
• Random sampling and testing: Some medical devices may be randomly selected for testing to assess their performance, durability, and safety under real-world conditions.

7. Impact of Global Trends and Standards

As part of China’s increasing focus on international harmonization, the NMPA regularly updates its regulations to align with global standards, such as those set by the International Medical Device Regulators Forum (IMDRF) or the International Organization for Standardization (ISO). Manufacturers must stay up to date with these changes to ensure ongoing compliance. Periodically, devices may be reviewed to ensure they meet the latest international regulatory standards, which could require additional testing, documentation, or quality control measures.

Conclusion

In China, medical devices do indeed require regular reviews throughout their lifecycle. While the initial registration is a key milestone, ongoing post-market surveillance, periodic re-registration, and continuous compliance with evolving regulations are critical to maintaining a device’s legal status in the market. Manufacturers must be proactive in ensuring that their devices adhere to regulatory changes, monitor post-market performance, and address any potential safety issues promptly. Regular reviews help ensure that medical devices maintain high safety standards and continue to meet the evolving needs of healthcare providers and patients.
