Post-market surveillance reporting requirements are different depending on the classification of the devices the PMS system is covering. This article provides an overview of PMS reporting according to medical device classification. 

PMS reporting for class I medical devices 

For class I devices, the manufacturers shall set up a PMS report summarising the results and conclusions of the analyses of the post-market surveillance data. This is gathered as a result of the PMS plan, together with a rationale and description of any preventive and corrective actions taken.  

This report shall be updated by the manufacturer when necessary and made available to the competent authority upon request. 

PMS reporting for class IIa and higher classes of medical devices 

For class IIa devices, the manufacturer must set up a periodic safety update report, a PSUR. This is the PMS report for manufacturers of class IIa, IIb and III devices.  

Medical device class Report Update frequency Make available to notified body
Class I
PMS report
Updated as necessary
Class IIa
Updated as necessary but at least every second year
Class IIb and III
Updated as necessary but at least annually
Class III and implantable devices
Uploaded to EUDAMED for notified body assessment

The PSUR shall, as well as the PMS report required for class I devices, summarise the results and conclusions of the analyses of the PMS data gathered according to the PMS plan together with a rationale and description of any preventive and corrective actions taken. 

The PSUR shall also include (not for class I devices): 
(a) the conclusions of the benefit-risk determination; 
(b) the main findings of the PMCF; and 
(c) the volume of sales of the device and an estimate evaluation of the size and other characteristics of the population using the device and, where practicable, the usage frequency of the device. 

For class IIa devices, the PSUR shall be updated when necessary, but at least every two years.

For class IIb and III devices, this PSUR shall be updated as necessary but at least annually.

Making the PSUR available to a notified body

For class IIa and IIb, the PSUR shall also be made available to the notified body.

How to make the PSUR available to the notified body is not stipulated in the MDR, so this is something that the notified body of the manufacturer should state in its agreements. 

If the manufacturer creates implantable devices or class III devices, the PSUR shall be uploaded to EUDAMED for notified body assessment. The notified body, in turn, needs to upload its conclusions of the assessment to EUDAMED. This notified body assessment is not publicly available but only available for competent authorities.
