At first glance, the idea of a globally harmonized UDI system seems logical. Uniform identifiers, standardized data, and clearly structured processes should simplify the international trade of medical devices while strengthening patient safety. In reality, however, a far more complex picture emerges.
Despite international guidelines, regulatory systems continue to evolve differently across regions. This is precisely where challenges arise for manufacturers distributing their products globally. A good example of these challenges is the differences between AusUDID and EUDAMED. Both systems pursue similar goals, yet differ significantly in structure, data requirements, and usage. These differences are a key driver of the increasing fragmentation within the global UDI landscape.
Two Systems, One Goal, Different Approaches
A look at the fundamental design quickly reveals why AusUDID and EUDAMED differ so greatly. While the systems fulfill similar functions, they are conceptualized in entirely different ways.
AusUDID is a classic UDI database. It focuses on the structured capture and management of product data and is closely linked to the Australian approval system. Its primary focus is clearly on identification and regulatory reporting.
EUDAMED, on the other hand, goes much further. The system is designed as a central platform within the MDR and IVDR frameworks and integrates multiple regulatory processes into one system. These include six modules:
- Actor registration
- UDI and product registration
- Notified bodies and certificates
- Clinical investigations and performance studies
- Vigilance and post-market surveillance
- Market surveillance
For manufacturers, this means they must not only provide different data but also understand different system roles. While AusUDID represents more of a single building block, EUDAMED functions as a central infrastructure.
Data as a Fragmentation Factor
The most significant operational impacts of the differences between AusUDID and EUDAMED are reflected in how data is handled and in its scope. Although both systems are based on the UDI principle, their detailed requirements differ considerably.
The following overview highlights the key differences:
| AusUDID | EUDAMED | |
| Core focus | Device identification (UDI-DI, UDI-PI) | Holistic management of medical device data |
| Data scope | Limited to core product attributes | Product attributes plus regulatory context information from modules |
| Level of detail | Moderate, more standardized | Very high, with numerous mandatory fields |
| Data dependencies | Lower complexity | High complexity due to interlinked fields |
| Data updates | Updated when specific changes occur | More frequent updates due to module interconnections |
These differences have direct implications for day-to-day operations. Data often cannot simply be transferred but must be adapted and partially restructured.
Typical consequences include:
- Parallel maintenance of multiple datasets
- Required mapping between classifications
- Increased complexity when making changes
This is exactly what makes these differences so critical for data quality and compliance. Double the data volume means double the potential sources of error.
Differences in Implementation
In addition to data, the implementation and use of the systems also play an important role. Both systems are introduced gradually, but with different priorities and dynamics.
EUDAMED is structured in multiple modules. Originally, all modules were intended to be released and become mandatory simultaneously. Due to the system’s complexity and challenges in development, however, they have been released and mandated step by step. In practice, this has already resulted in numerous deadline postponements, leading to planning uncertainty. Manufacturers have had to keep their strategies flexible accordingly.
AusUDID is also being introduced in phases, but these are based on product classes. This often makes planning easier, although flexibility remains important.
Operational and Strategic Impact for Manufacturers
For manufacturers, the differences between AusUDID and EUDAMED are most noticeable in daily operations. Fragmentation leads to more processes, increased coordination efforts, and higher risk. Typical error sources, such as inconsistent data, can in the worst case result in delays in market access.
At a strategic level, it becomes clear that isolated, regional solutions are no longer sufficient. Many companies therefore rely on centralized data management. The focus is on:
- Master data management as a control instrument
- Global UDI strategies with local adaptation
- Standardized data models as a foundation
This development is no coincidence. Additional markets are already working on their own UDI systems, which, like AusUDID and EUDAMED, are based on international standards but interpret them differently.
In the end, one key insight remains: the hope for full harmonization has not yet been realized. For manufacturers, it will be crucial to view fragmentation not as an exception, but as a permanent feature of the regulatory landscape.
How Can tracekey Help?
One approach to better manage growing fragmentation is the use of a centralized UDI management tool. The mytracekey UDI Manager makes it possible to serve AusUDID, EUDAMED, and other regulations from a unified data foundation. Instead of maintaining data multiple times, it is managed centrally and then transformed and transmitted in a system-specific way. This not only reduces operational effort but also minimizes inconsistencies between systems. Especially given the significant differences between AusUDID and EUDAMED, such a centralized approach is increasingly becoming a key factor for success for many manufacturers.
