[Comparative study of medical device classification between China and USA]

Area of Science:

• Regulatory Science
• Health Policy

Background:

• Medical device classification is crucial for ensuring product safety and efficacy.
• Existing regulatory frameworks vary significantly across different countries.
• China's medical device classification system has undergone revisions to align with international standards.

Purpose of the Study:

• To compare the medical device classification systems of China and the USA.
• To identify inherent challenges and limitations within China's current classification framework.
• To propose actionable recommendations for improving China's medical device regulatory system.

Main Methods:

• Comparative analysis of the regulatory structures and classification criteria for medical devices in China and the USA.
• Review of relevant national regulations and guidelines from both countries.
• Identification of discrepancies and areas for improvement in the Chinese system.

Main Results:

• Significant differences were observed in the classification principles, risk-based approaches, and nomenclature between the Chinese and US systems.
• Several critical issues were identified in China's classification system, including ambiguity in certain categories and lack of harmonization with international standards.
• The US system demonstrates a more robust and detailed risk-based classification approach.

Conclusions:

• China's medical device classification system requires further refinement to enhance regulatory clarity and international alignment.
• Adopting principles from the US classification system can address identified shortcomings and strengthen China's regulatory oversight.
• Harmonization efforts are essential for facilitating global trade and ensuring consistent patient safety.
