Performing a methodologically sound literature review in the early stages of product development, as well as in the later stages, can help reduce most of the inadequacies highlighted by the European Commission in section A6 of MEDDEV 2.7/1 revision 4. Section A6 provides examples of studies that lack scientific validity for the demonstration of adequate clinical performance and/or safety.
Here are the seven areas highlighted in section A6 of MEDDEV 2.7/1 revision 4 that manufacturers tend to have the most problems in proving scientific validity:
In a recent post, we talked about one of the most challenging areas of the CER: Defining Measurable Safety and Performance Endpoints
The first deficiency listed, “lack of information on elementary aspects,” can obviously be improved using a robust systematic literature review. Defining the evaluation criteria is the first step in performing a methodologically sound systematic literature review, and these sections would then fall into place. For example, one criterion would define the clinical study methods, while other criteria might include clearly defining results to be included, undesirable side effects, and the intended-to-treat population. A scientifically sound approach and well-organized data management plan can bring all the clinical data together and allow for a thorough understanding of where the device is in the process of obtaining an CE marking.
Less obvious is how a methodologically sound systematic literature review can help with some of the other CER deficiencies. Let’s look at the three points in a devices lifecycle in which clinical evaluation is undertaken: development of the medical device (section 6.2.1), initial CE-marking (section 6.2.2), and updating the clinical evaluation (section 6.2.3).
The systematic literature review can be an effective tool early in the development of the medical device for gap analysis and determining State-of-the-Art. Once all the clinical evidence is gathered it is much easier to see if the publications and report documents have conclusive preliminary data or if further clinical data is required before moving forward with CER submissions. And, closely evaluating the complied data makes it easier for manufacturers to note statistical methods in the supporting data, and the potential of bias.
Of course, not all inadequacies can be addressed with a systematic literature review, such as improper collection of mortality and serious events data that rely on a different process for review. It is always important to collaborate with your organization’s regulatory authorities or a regulatory specialist to make sure you are complying in these areas.
Following leading practices and presenting clinical data in a straight-forward manner helps manufacturers be in good position to help regulatory agencies not to have to say No to your CER submission. Lack of organization and transparency can create a cycle of generating responses to regulatory agencies and delays getting devices to market.
Systematic literature reviews can help you find gaps in information that may be needed for inclusion in the CER, as well as putting your best foot forward by strongly providing sufficient clinical evidence for the evaluation of safety and performance of the device. Regulatory agencies expect this level of compliance. We can help you meet the challenge. We are experts in this area. Check out our recent webinars to better understand the process.
At Criterion Edge, we are experts at generating methodologically sound systematic literature reviews and state-of-the-art reports to ensure your CER is ready for review by notified bodies. And, we can help ensure the scientific validity is adequate and document the methods we use for data collection. Talk to us about running a systematic literature review for you.

All medical devices sold in Europe must have a Clinical Evaluation Report (CER), and specific and measurable safety and performance endpoints are paramount for an acceptable CER. However, many small medical device manufacturers are struggling to adequately define and subsequently document measurable safety and performance endpoints, especially in the literature review, to support an evidence-based evaluation.
The newest regulations for medical devices, Medical Device Regulation (MDR) 2017/745 and MEDDEV 2.7/1 revision 4, set high standards for confirming safety and performance when using the device according to the manufacturer’s Instructions for Use. Regulations under the old MDR and MEDDEV were not as demanding, and manufacturers are not accustomed to the current systematic process of CER evaluations.
These relatively new requirements for clinical evaluation extend to manufacturers trying to get new products into the European market, as well as those that are already selling medical devices. Safety and performance are central components of the evidence-based evaluation process for obtaining and maintaining CE Marking for MDR 2017/745 and MEDDEV 2.7/1 rev 4, and medical device manufacturers are expected to be in full compliance by May 26, 2020*. For manufacturers that already have products on the market, the CER must be updated throughout the product lifecycle.
For more information on the role of CERs in obtaining CE Marking for legal marketing in the European Union (EU), see Criterion Edge’s article What role does the CER play in getting a Medical Device Approved for Marketing in the EU?
Systematic literature reviews (SLRs) are a big part of the CER. The ultimate goal of the CER is to provide sufficient clinical evidence that the device achieves its intended purpose and is safe and effective. MEDDEV 2.7/1 rev 4 Section 4 defines evidence-based as:
Note that this list is comprised primarily of endpoints that need to be generated by performing methodologically sound systematic literature reviews.
Clearly setting safety and performance objectives in the review of scientific literature proves to have its own special challenges. Conducting systematic literature reviews requires expertise, people, and time.
A systematic literature review is much different than an internet–based literature review for a scientific manuscript. It requires a clear and methodologically sound search strategy coupled with a robust literature search. Every decision needs to be documented.
There are many circumstances in which using experts in some areas of CER preparation can fill in gaps where expertise may be needed, or time is of the essence. To determine if hiring a consulting expert to facilitate timely and expert CER development, ask your organization these questions.
Does your team meet all the criteria for preparing the clinical evaluation?
Does your team know how to document the methods used to generate systematic literature reviews?
Are they familiar with what aspects to consider when determining relevance?
Do they have the time to perform systematic literature reviews?
