2020 Adverse Events Report Released: Infusion, Protection and Monitoring Devices Had Most Complaints


NMPA issued 2020 Adverse Events Report on March 22, 2021, summarizing over 530,000 reports, 35.25% rise from the year before.

“Medical device manufacturers should take the initiative to collect all suspicious medical device adverse events in their products from medical device operators and users. Enterprises that produce Class II and Class III medical devices should also establish corresponding systems to ensure the traceability of their products.”, according to Decree 1 “Medical Device Adverse Event Reporting and Reevaluation” issued in August 2018.

Legal representative will play a far more significant role than ever before, as Decree 1 requires all the adverse events information be provided to your legal representative to compile and report to China regulatory authority. It is important to collect the information and make them available to your legal representative because NMPA increasingly relies on post-market surveillance to achieve full regulatory compliance.
