In the past, the ECA has often reported about the Unique Device Identifier topic. Please see the GMP News "What's new from the FDA regarding Medical Devices?" from 4 September for the last report.
In the meantime at the FDA, the Unique Device Identifier (UDI) and Global Unique Device Identification Database (GUDID) topics have taken on great importance: the FDA has even developed a own website dedicated to these topics. Currently - dated January 2015 - you can find on an independent website records from webinars on UDI and GUDID. Fortunately, the slides presented during the webinars are also available. The set of slides regarding the UDI webinar contains 30 pages and 38 additional slides are available on the GUDID topic.
For more information please see the set of slides Unique Device Identifier (UDI) and on Global Unique Device Identification Database (GUDID).
Conclusion: For those who want to get a quick overview of the topic areas UDI and GUDID with regard to FDA's requirements, it is recommended to have a look at both sets of slides from the respective webinars.
