Data Elements of Basic EU UDI & References to EU UDI - Alysidia

December 21, 20200

As the European Commission is unveiling the enforcement of MDR and IVDR, and with the inception of EUDAMED, a lot of concern is now also there on the Basic EU UDI as well along with individual UDI-DI-PI. It is important to understand the concept of basic EU UDI as per the regulations along with its data elements. As per Regulation (EU) 2017/745 (MDR) and Regulation (EU) 2017/746 (IVDR) Annex VI Part C definition:

“The Basic UDI-DI is the primary identifier of a device model. It is the DI assigned at the level of the device unit of use. It is the main key for records in the UDI database and is referenced in relevant certificates and EU declarations of conformity.”

The Basic UDI-DI is the leading entranceway in the database and applicable documentation. Some of the documents which are relevant for the Basic UDI-DI are listed as under:

  • Certificates
  • Declaration of conformity
  • Technical documentation
  • Summary of safety
  • Clinical performance

The purpose of the basic UDI is to group medical devices with similar anticipated purpose, risk class, and important design and production features. It is however not associated with the individual packaging and labeling of the medical device and it does not appear on any shipped product.

Any Basic UDI-DI must identify the group of medical devices showcased by that Basic UDI-DI in a traceable manner.
