  • When are vigilance reports required in South Korea?
  • What is considered a severe adverse event by Korean authorities?
  • What are the steps in the Korean vigilance process?

The South Korea’s Ministry of Food and Drug Safety (MFDS) requires medical device manufacturers to comply with a vigilance system for post-market monitoring and adverse event reporting.

Companies that fail to accurately report incidents to could face severe financial penalties or even criminal sentences. Korean authorities do not accept ignorance as an excuse for failing to implement a vigilance system for South Korea, so you must be proactive.

When are vigilance reports required in South Korea?

You or your Korean License Holder (KLH) should report adverse events to the MFDS. Adverse events occurring in South Korea must be reported if they lead to death, serious injury, or any of the following scenarios:

  • hospitalization or an extension of hospitalization
  • irreversible injury, serious disability and decrease of function
  • congenital deformity or abnormality

If a recall is necessary, it must be classified as Class I, II, or III (nothing to do with your device classification) based on severity and submitted with a recall plan to MFDS for review. The recall plan should also include a strategy for informing consumers about risks associated with the medical device. The Code for Patient and Medical Device Event shall be selected from the MFDS Notification, and a document stating the reason of the recall should be submitted.

South Korea MFDS vigilance reporting process

Below are the basic steps for reporting an adverse event with your medical device in South Korea:

  • Inform your Korea License Holder and the Ministry of Food and Drug Safety (MFDS) that a reportable adverse event has occurred.
  • Investigate the cause of the adverse event and report all findings to the MFDS.
  • Determine recall classification, Patient Code, Medical Device Event Code, and inform MFDS.
  • Report final outcomes of the adverse event investigation and corrective action to the MFDS.
  • Add all reports, along with any correspondence with the MFDS to your Quality Management System records.
  • Your KLH should include adverse events in annual reports submitted to MFDS.
