Post-Market Surveillance for Medical Devices in South Korea

In South Korea, post-market surveillance (PMS) is a critical component of medical device regulation. The Ministry of Food and Drug Safety (MFDS) enforces stringent requirements to ensure the continued safety and performance of medical devices once they are on the market. This article outlines the South Korea post-market surveillance medical devices framework, including MFDS vigilance reportingadverse event reporting in Korea, and field safety corrective actions (FSCA)—and how OMC Medical can assist with compliance through its local presence in South Korea. 

What is Post-Market Surveillance in South Korea? 

Post-market surveillance in South Korea refers to the set of activities mandated by the MFDS to monitor the safety, efficacy, and quality of medical devices after they have been approved and made available on the market. These activities are primarily governed under the Medical Devices Act and its related enforcement rules. 

Manufacturers, importers, and distributors must implement robust surveillance systems to track real-world device performance and report any adverse incidents.

MFDS Vigilance Reporting System 

The MFDS vigilance reporting framework is built around proactive identification and communication of safety issues. Key stakeholders—including manufacturers and importers—must report any incidents or risks associated with medical devices to the MFDS. 

Mandatory Reporting Includes: 

  • Device malfunctions that could lead to patient harm 
  • Deterioration in device performance 
  • Labeling errors 
  • Biological or chemical contamination 

Reports must be submitted via the MFDS Medical Device Information System (MDIS). Timelines for reporting vary depending on the severity of the incident: 

  • Serious adverse events: Within 7 days 
  • Non-serious events: Within 15 days 

Adverse Event Reporting in Korea 

Adverse event reporting in Korea is a central obligation under PMS regulations. An adverse event includes any unintended, harmful occurrence associated with the use of a medical device. 

Responsibilities Include: 

  • Continuous monitoring of device usage 
  • Collecting user and healthcare provider feedback 
  • Submitting follow-up reports if new information becomes available 

Failure to report adverse events may result in administrative penalties, product recalls, or suspension of device licenses

Field Safety Corrective Action Korea 

When safety issues are identified, the MFDS may require a field safety corrective action (FSCA) in Korea. This involves urgent and strategic measures taken to reduce risk, such as: 

  • Device recalls 
  • Software corrections 
  • Replacement or modification of affected devices 

Manufacturers must submit a Field Safety Notice (FSN) detailing the corrective action, risk assessment, and communication strategy to affected users. The FSN must be pre-approved by the MFDS before implementation.
