In focus: UDI international

In 2017, the European Commission launched the MDR and thus also the Unique Device Identification (UDI). Europe is not alone in this. The concern to make medical technology products safer is also being implemented in other countries with corresponding initiatives or is in the planning phase.

The WHO and other organizations have been working for some time on the standardization of regulations concerning the safety of medical technology products. As early as 2013, the International Medical Device Regulatory Forum (IMDRF) published a framework of conditions to establish an internationally uniform standard for unique device identification.

The framework conditions of the IMDRF

– A Unique Device Identifier (UDI) at each packaging level according to international standards

– UDI consists of Device Identifier (DI) and Product Data (PD), such as batch number or expiration date

– UDI is machine-readable and human-readable on the label

– Data is maintained in a central UDI database

Similar to drug tracking, the introduction of unique identification systems for medical technology products is not only underway in Europe and the USA, but also in many other countries. In Brazil, the regulations will only apply to hip and knee implants and stents (heart). India wants to introduce a comprehensive UDI as of 2022.

Starting next year, the voluntary program will also become mandatory in Taiwan and Saudi Arabia. In South Korea, the UDI will be introduced by 2022, similar to Europe’s tiered risk classes. China is currently working on another pilot project which is supposed to run until July 2020. Turkey, Russia, and Australia are also working on similar systems or are already implementing them.

Lack of unity makes things complicated

Other countries, on the other hand, have introduced systems for the identification of medical technology products whose benefits are not concentrated on patient safety and post-market surveillance, but where the focus is on traceability, i.e. the entire curriculum vitae is documented. These include Japan, the United Kingdom, and Argentina. The latter has only introduced traceability for implants.

Despite the IMDRF, the systems and, above all, the concrete designs are very different. This creates hurdles that affect the international applicability of medical technology.

UDI: Example Code

A 2D data matrix code, can hold more data in a smaller space, but it also needs other scanners than a linear barcode. This poses problems for the last scanning instance, for example for hospitals, as they may have to adapt to different codes. Manufacturers, on the other hand, have to provide different versions of their data sets for the different markets, which they have to feed into the different databases.

In the USA and Turkey, information on MRI compatibility is required. In Turkey, a distinction is only necessary between yes and no, but in the USA a distinction is made between secure, insecure and conditionally secure. Although the same product attributes are queried here, the concrete design of the data is different.

A solution for global demands

Overall, all systems are more or less blueprints based on WHO guidelines. However, the national design increases the effort for internationally operating medical technology manufacturers. If the manufacturers want to react flexibly to new requirements in the future and act compliantly on a global level, a database is not enough.

The above-mentioned obstacles must be taken into account in the software. A smart solution provides information about which information a medical technology manufacturer must keep on file for the respective product in the respective country and which external business partners have write permission in the database to guarantee actuality and accuracy. Besides, it must be ensured that the data for the entire service life of the product is always up-to-date and synchronized with the corresponding national database. Also, a workflow is required to ensure that data collection and synchronization also takes place “internally” between the business partners involved (contract manufacturers, marketing authorization holders, etc.) and their systems, so that the data stored in EUDAMED, for example, also correspond to the printed information on the packaging. These are all factors that can easily be overlooked because medical technology manufacturers are busy until the deadline of 2020 mainly with the (re-)approval of their products. Nevertheless, they should not forget this important aspect.
