Medical Device PMS in China
Effective post-market surveillance (PMS) is essential for maintaining the safety and performance of medical devices after they have been introduced to the Chinese market. Under China's evolving medical device regulation, the National Medical Products Administration (NMPA) mandates that In-Vitro Diagnostic (IVD) and medical device manufacturers establish and maintain a compliant PMS system to ensure long-term safety, effectiveness, and market access.

What is Post-Market Surveillance (PMS)?
Post-market surveillance (PMS) refers to the ongoing process of monitoring the clinical performance and device performance of medical devices and IVDs once they are commercially available. In contrast to pre-market clinical trials, PMS collects real-world clinical data through user feedback, adverse events, and market observations to ensure ongoing medical device safety.
In China, a robust post-market surveillance framework is legally required and forms an essential part of the broader quality management system. It plays a critical role in identifying risks that could lead to serious adverse health consequences or serious incidents, particularly for high-risk Class III devices.
PMS in China: Regulatory Overview
The NMPA has significantly expanded its focus on post-market surveillance, introducing regulations that emphasize real-world data, proactive risk control, and continuous compliance. Under these regulations, manufacturers must:
Manufacturers have specific responsibilities under NMPA regulations to ensure compliance with these requirements, including the implementation of post-market surveillance plans and maintaining the safety and performance of medical devices.
Noncompliance with these regulatory requirements may lead to enforcement actions, including certificate suspension or market withdrawal.
Core Components of a PMS System under the NMPA
To effectively meet China’s PMS requirements, IVD and medical device manufacturers must implement a structured system encompassing the following components:
1. PMS Plan Development
Every manufacturer must prepare a comprehensive PMS plan or post-market surveillance plan tailored to each product. This plan outlines procedures for data collection, data analysis, reporting, and initiating corrective and preventive actions (CAPA). A comprehensive PMS plan outlines data sources, analysis methods, and action thresholds. It should be regularly reviewed and updated to reflect current NMPA regulations and device performance insights.
2. Adverse Event Monitoring
Daily monitoring of the NMDAEM System enables early identification of risks, especially for events that could result in adverse health consequences. AE reports must be reviewed, translated if necessary, and submitted to NMPA within prescribed timelines.
3. PRER & PMS Reports
Manufacturers of Class II and III devices must compile and submit PRERs (PMS reports) that summarize cumulative risk data, trend analysis, and any resulting risk mitigations.
4. Corrective & Preventive Actions (CAPA)
CAPAs are initiated in response to identified issues. These actions must address root causes, be well-documented, and include follow-up monitoring to verify effectiveness.
5. Label & IFU Compliance
Chinese-language labels and Instructions for Use (IFUs) must be reviewed to confirm they meet the NMPA’s content and formatting standards, including accurate legal agent and manufacturer details.
6. UDI & Traceability
For devices subject to China’s UDI regulation, manufacturers must maintain updated UDI-DI codes in the NMPA database and ensure traceability throughout the supply chain.
7. Annual Summary Reports
An annual summary of all PMS activities, including adverse event trends and effectiveness of CAPAs, must be compiled and retained for audit readiness.
8. Integration with QMS
PMS processes should be embedded within the organization’s ISO 13485-certified QMS to ensure a seamless approach to compliance and continuous improvement.
Common Challenges in China PMS Compliance
PMS implementation in China is not without obstacles. IVD and medical device companies often encounter:
Solutions include:

Post-Market Surveillance as Part of a QMS
Embedding PMS into the QMS framework ensures consistent, organization-wide awareness of safety obligations. A QMS is essential for meeting international standards like ISO 13485:2016, ensuring compliance with regulatory obligations. This alignment supports:
Many manufacturers report better regulatory performance and reduced product release delays after integrating PMS activities into their core QMS.
For medical device companies in China, post-market surveillance is more than a compliance requirement, it is a strategic pillar of safe, effective, and sustainable operations. By aligning with NMPA’s PMS framework and integrating surveillance activities into your QMS, you enhance regulatory readiness, improve product safety, and strengthen patient trust. Active monitoring and a proactive, well-documented PMS system are the foundation for long-term success in the Chinese medical device market.
