- Determination of threshold values for assessing risk-benefit ratios
- Protocols for effective communication with regulatory authorities and users
Manufacturers must ensure that their PMS plan is tailored to the specific device type and proportionate to its risk class. The plan should be integrated into the company’s quality management system and regularly updated to reflect new information and changing regulatory landscapes.
Periodic Safety Update Report (PSUR)
The Periodic Safety Update Report (PSUR) is a critical component of post-market surveillance documentation, particularly for higher-risk devices. PSURs are required for Class IIa, IIb, and III medical devices under the EU Medical Device Regulation (MDR), and for Class C and D IVDs under the In Vitro Diagnostic Regulation (IVDR).
A PSUR should provide a comprehensive and critical analysis of the risk-benefit balance of the device, taking into account new or emerging safety information in the context of cumulative data on risks and benefits. The report must include:
- Results and conclusions of data gathered from the PMS plan
- An update on the benefit-risk determination
- Main findings of post-market clinical follow-up or performance follow-up
- Sales volume and estimated user population characteristics
- Usage frequency of the device
- Description of any preventive and corrective actions taken
PSURs must be updated at least annually for Class IIb and III devices, and every two years for Class IIa devices. These reports are essential for manufacturers to demonstrate ongoing compliance and for regulatory authorities to assess the continued safety and performance of devices on the market.
Post-Market Surveillance Report
For lower-risk devices, such as Class I medical devices under the MDR and Class A and B IVDs under the IVDR, manufacturers are required to produce a Post-Market Surveillance Report (PMSR). This report is similar to the PSUR but with less extensive requirements.
The PMSR should present:
- Results and conclusions of data gathered from the PMS plan
- A rationale and description of any corrective and preventive actions taken
- An assessment of the device’s continued conformity with regulatory requirements
While less comprehensive than the PSUR, the PMSR is still a crucial document for demonstrating the ongoing safety and performance of lower-risk devices. It provides regulatory authorities with valuable insights into the real-world use of these products and helps identify any potential issues that may require further investigation or action.
In conclusion, effective post-market surveillance documentation is essential for maintaining regulatory compliance and ensuring the continued safety and performance of medical devices and IVDs.

Vigilance Reporting and Field Safety Corrective Actions
Vigilance reporting and field safety corrective actions (FSCAs) are crucial components of post-market surveillance for medical devices and in vitro diagnostics (IVDs). These processes help ensure the ongoing safety and effectiveness of devices throughout their lifecycle.
Adverse Event Reporting
Manufacturers have a legal obligation to report adverse events involving their medical devices to regulatory authorities. In the United States, the FDA receives over two million medical device reports of suspected device-associated deaths, serious injuries, and malfunctions each year. This reporting system, known as Medical Device Reporting (MDR), serves as a vital postmarket surveillance tool for monitoring device performance and detecting potential safety issues.
Under the MDR regulation, manufacturers must report to the FDA when they learn that any of their devices may have caused or contributed to a death or serious injury. They must also report device malfunctions that would be likely to cause or contribute to a death or serious injury if they were to recur. These reports must be submitted within specific timeframes, depending on the severity of the incident.
Trend Reporting
Trend reporting is an essential aspect of post-market surveillance, particularly for in vitro diagnostic devices under the IVDR. Manufacturers are required to report any statistically significant increase in the frequency or severity of incidents that are not serious but may pose risks to health or safety. This includes reporting significant increases in expected erroneous results compared to the stated performance of the device.
Implementing effective trend reporting allows manufacturers to gain valuable insights into the performance, safety, and effectiveness of their devices in real-world settings. By closely monitoring trend reports, manufacturers can identify patterns or emerging issues that require further investigation or corrective actions. This proactive approach enables the maintenance of a favorable benefit-risk ratio throughout the device lifecycle.
Recall Management
When a medical device poses a risk to patient safety, manufacturers may need to initiate a recall. Recalls are usually conducted voluntarily when manufacturers discover a problem with a device. However, in rare cases, the FDA can require a recall if a medical device company refuses to address hazardous product malfunctions.
The recall process involves several key steps:
- Determining the need for a recall
- Conducting a risk assessment
- Notifying the FDA District Office
- Executing appropriate recall actions
- Improving product quality for the future
Manufacturers are responsible for developing a recall strategy that addresses the depth of recall, the need for public warnings, and the extent of effectiveness checks. They must also provide regular status reports to the FDA, detailing the progress of the recall, including the number of consignees notified, the quantity of products returned or corrected, and the estimated timeframes for completion.
In conclusion, vigilance reporting, trend analysis, and recall management are critical components of an effective post-market surveillance system. By implementing robust processes for adverse event reporting, trend analysis, and recall management, manufacturers can proactively identify and address potential safety issues, ensuring the ongoing safety and effectiveness of their medical devices and IVDs throughout their lifecycle. This proactive approach not only helps maintain regulatory compliance but also contributes to continuous improvement and innovation in the medical device industry.
