In the complex landscape of In vitro diagnostic regulation (IVDR), the role of Notified Bodies is crucial yet often misunderstood. These organisations are responsible for assessing the conformity of certain products before they can be marketed in the European Union (EU). However, the system is fraught with challenges.
Understanding Notified Bodies
Notified Bodies are independent organisations designated by EU member states to assess the conformity of products with the applicable regulatory requirements. They play a pivotal role in ensuring that products are safe and effective for use. Their responsibilities include conducting audits, reviewing technical documentation, and performing product testing. Notified Bodies are used for a wide range of European Regulations, including for medical devices and IVDs. This is important to note if a device comes under a number of Regulations, the EU AI Act for example, where an NB is required not just for the IVDR.
Notified Bodies are assigned a Notified Body Code which should be included next to the CE mark of a device placed on the EU market under IVDR (e.g. NB 0123 TUV SUD Product Service GmbH). This way the user can easily identify who has completed the conformity assessment for the device.
In my experience, engaging with a Notified Body is a positive experience, if you plan correctly. Let’s face it, we all want the same thing: to bring safe and effective IVDs to market within an efficient process compliant to the regulation.
The Conundrum
The conundrum arises from several interrelated issues:
1. Limited Capacity
Although the number is increasing, there is still a limited number of Notified Bodies, and their capacity is often stretched thin. This can lead to delays in the certification process, impacting the time it takes for new medical devices to reach the market.
2. Stringent Requirements
The introduction of the In Vitro Diagnostic Regulation (IVDR) has significantly increased the regulatory requirements. Notified Bodies must now adhere to more stringent criteria, which has further strained their resources.
3. High Demand
The demand for Notified Body services has surged, partly due to the increased regulatory requirements and partly due to the growing number of medical device manufacturers seeking certification. This high demand exacerbates the capacity issues.
4. Complexity of Assessments
The assessments conducted by Notified Bodies are complex and require a high level of expertise. This complexity can lead to longer assessment times and higher costs for manufacturers.
Impact on the Industry
The Notified Body Conundrum has several implications for the medical device industry:
Market Delays
Delays in the certification process can slow down the introduction of innovative medical devices, potentially impacting patient care and the competitiveness of manufacturers.
Increased Costs
The complexity and length of the certification process can lead to higher costs for manufacturers, which may be passed on to consumers.
Regulatory Uncertainty
The evolving regulatory landscape and the challenges faced by Notified Bodies can create uncertainty for manufacturers, making it difficult to plan and execute product development strategies.
Potential Solutions
Addressing the Notified Body Conundrum requires a multifaceted approach:
1. Harmonising Assessment Approach
Greater harmonisation of conformity assessment across the EU NB could help reduce the complexity of assessments and improve efficiency.
2. Leveraging Technology
The use of advanced technologies, such as artificial intelligence and machine learning, could help streamline the assessment process and reduce the burden on Notified Bodies.
3. Structured Dialogue
The utilisation of Structured Dialogue before and during the conformity assessment process improves the efficiency and predictability of the conformity assessment process. From my experience, this offers valuable insights into the expectations of the NBs as part of the conformity assessment journey. Note: this dialogue should not be used for getting consultancy from the NBs.
UK Approved Bodies
The UK follows a similar approach where the MHRA recognise a series of Approved Bodies. The list of approved bodies can be found on the MHRA website. While many EU Notified Bodies have a UK Approved Body, there are less ABs to choose from. At the time writing, there are 6 IVD UK Approved Bodies under the UK Medical Device Regulations (2002).
Note: This applies to Great Britain only, Northern Ireland come under the EU IVDR.
My top tips on engaging with a Notified Body
When preparing for conformity assessment, I would recommend the following:
- Early engagement with a notified body is key.
- Understand your device and its intended purpose before you make the NB application. They will want to know what the device is as part of the initial discussion.
- Don’t expect a quick turnaround. While initial engagement is generally quick and positive, most of the time is spent by the manufacturer understanding the device and gathering information (see bullet point 2)
- Be aware of costs and budget properly. The process isn’t cheap and requires significant investment of time.
- Don’t rush the technical documentation. The technical documentation you provide should be your best work, not throw it in and see.
Conclusion
The Notified Body Conundrum presents significant challenges for the medical device industry, but it also offers an opportunity for innovation and improvement. Don’t be afraid of engaging with a Notified Body but take your time to find the best fit for your organisation and product. There is more choice available, with a greater amount of information and guidance to support the industry bring new products to market or maintain market access for legacy products.
If you need support, selecting, engaging, or building documents ready for conformity assessment, IVDeology is well placed to support you and your organisation bringing devices onto the EU and UK market.
