What is a Clinical Evaluation Report For Medical Device?

A well-researched Clinical evaluation report assures regulators such as notified bodies, competent authorities, patients, and clinicians alike the confidence that medical devices have been validated by strictly following guidelines, thus ensuring that their potential benefits outweigh any possible risks associated with their use. To create a uniform approach with manufacturers and notified bodies (NBs) involved in the conformity assessment procedures, MDR article 61 and legally non-binding MEDDEV 2.7.1 Rev 4 guidelines were used.

 

Article 61 requires the development and frequent updating of a clinical evaluation report for medical devices, which is used to review and analyze clinical data regarding a medical device in order to validate its clinical safety and performance. All medical device manufactures must demonstrate that their products fulfil the 2017/745 general safety and performance requirements (GSPR). To meet these obligations, medical device manufactures must review existing data and develop a CER in accordance with MDR Article 61 and Annex XIV, which covers post market surveillance data covering post market clinical follow up data too.

 

The clinical evaluation report is a key component of the CE Marking process, so both are connected together. Market a device on the European union must need CER and maintain that ,the EUMDR emphasize the importance of the CER and include general safety and performance requirements,  clinical evaluation review and documentation.

 

To obtain CE Certification or to apply the CE Mark to a medical device, we must have a thorough CER inside the technical file. The EU 2017/745 has specific requirements for medical device clinical evaluation report documentation and data analysis. I3CGLOBAL is one of the top talented service providers.

Regulation and Guidance For Clinical Evaluation Report

MDR article 61- section 12 and Annex XIV – Part A- section 4 states the requirement for a CER. Complete clinical evidence collected during the clinical evaluation process is to be documented in CER and it shall be a part of the technical documentation which will support the assessment of the conformity of the device.

 

MEDDEV 2.7/1 Rev.4 Clinical Evaluation: A Guide for Manufacturers and Notified Bodies Under regulation for Clinical Evaluation, and Stage 4 states about the requirement of a CER. As per this guidance, the CER report should contain enough information to be read and understood by an independent party such as a regulatory authority or notified body.  Thus, it should provide enough detail for understanding the search criteria adopted by the evaluators, data that are available, all assumptions made, and all conclusions reached.

Steps to create a good Clinical Evaluation Report?

MDR Article 61 and MEDDEV 2.7.1 Rev. 4 guidelines are not easy to understand, particularly due to the type of your device, risk class, changes in design, state of the art, features, treatment goals, intended use, and intended patient groups. The above guidelines only allow manufacturers with concepts to choose the right method and create CER independently. It leads to considerable frustrations on CER Team. We created this page to provide additional inputs for the good CER documentation. The fundamental rule behind CER is the below,

 

♦  The clinical evaluation report must be objective, no matter the data is positive or negative.

♦  CER should be thorough enough to build confidence among NB reviewers and subject experts.

♦  CER of established devices can rely on existing market data, whereas novel devices data similar and equivalent devices.

Step 1: Identify the scope of Clinical Evaluation.

Scope of the clinical evaluation should include the identification of devices covered by this clinical evaluation report, products, models, sizes, software versions, accessories, whether it is on the market, since when, in what regions, history of the device, in case of update in the plan including date of past modifications with reasons and description, sales volumes, changes since the last report, identification of the sections of the CER that are concerned with the new information and have been modified should be mentioned.

Step 2: Clinical Evaluation Planning

To plan a sound method for identifying, collecting, and analyzing the clinical data with the proper schedule and clinical evaluation team. Also, to develop the scope of the clinical evaluation to be conducted on the medical device.

Step 3: Data generated and held by the manufacturer.

All premarket clinical investigations such as bench test reports include verification and validation data and clinical data generated from risk management activities and the PMS programs.

Step 4: Background, current knowledge, state of the art

A review of the current knowledge/state of the art needed for the proper conduct of the appraisal and analysis of the device’s clinical data under evaluation and the equivalent device.

 

Summary and justification of the literature search strategy applied for retrieving information on current knowledge, including sources, keywords, selection criteria used, quality control measures, results, number, and type of literature, were pertinent. Appraisal criteria were also used to summarize.

Step 5: Clinical data from the literature

The primary plan is to identify three key sources of data that can be in a clinical evaluation report. They are.  

 

  1. Trustworthy data /study comments published in medical journals. 
  2. Unpublished, internal data. 
  3. Complaint/post-market surveillance data. 
  4. registry data (for class 111 devices)

 

It is determining search criteria. 

 

Develop a well-defined plan of action (SOP) for searching the literature to make sure you attempt to find all possible data relevant to the device in question. The plan should consist of inclusion and exclusion criteria framed based on your device’s complexities and avoid analyzing the same data from multiple sources and reducing time searching.

Step 6: Summary and appraisal of data

Assess the overall quality of data that meets inclusion and exclusion criteria. The analysis of data allows determining how much merit the data bring towards the conclusion.

 

MEDDEV 2.7.1 Rev 4 Appendix C and D of the guidelines can be referred to understand more about suitability criteria and grading system.

Step 7: Complete Analysis

Analyzing the data in terms of their safety and performance is a big challenge because the quality of clinical data varies widely from study to study based on Safety, Risk Benefit profile, Performance & Acceptability of side effects.

  • The Clinical Evaluation Report should consider potential risks posed by the device that has been identified in the risk management report. All possible risks and risk control measures from the risk management report would need to be addressed in the CER conclusion.
  • Information about study population and diagnoses, intended purpose, adverse events should be analyzed in detail.

Presentation of Clinical study data with positive and negative approaches is highly advisable to present in CER. They are (a) Text-based summaries of individual studies or of individual endpoints (b) Visual summaries of pooled data. It is important to have a procedure that clearly defines your methodology followed in analyzing the data.

An equivalent device means

→  The clinical condition being treated, site of use in the body, and patient population. 

→  Medical Device Design, constructional materials, dimension, mode of operation).

→  Biological nature and characteristics

Systematic Literature Search is performed to identify suitable clinical data.

How to conclude a Clinical Evaluation Report

Article 61 and MEDDEV 2.7.1 Rev 4 guidelines must write precise conclusions to demonstrate conformity with the relevant general safety and performance requirements. It should address the following in detail.

 

  • According to current knowledge or state of the art in the medical fields concerned and according to available medical alternatives, the benefit-risk profile’s acceptability is concerned.
  • Adequacy of the manufacturer’s information materials, if the intended purpose and risk reduction measures are adequate, discrepancies.
  • The suitability of the device for human usage is to be demonstrated via usability engineering accepts. The user manual or information for use (IFU) must be circulated along with the device.
  • Level of acceptance with manufacturer claims and foreseen discrepancies.
  • Any inconsistence with supplied documents and clinical data must be detailed and explained regards with current knowledge and state of art
  • Unanswered questions or uncertainties derived during risk-benefit analysis and later accepted post-data interpretation of PMS results must be explained and justified thoroughly.
  • Several registries have been set up around the globe to record device-specific outcomes. However, the quality of these registries varies considerably. The conclusion must explain if you excluded some parts due to language problems or any other reason.
  • Data collected and analyzed by field staff must be detailed in CER
  • The conclusion must have an open debate and a walk-through to your Post Market Surveillance Data as part of the in-house study data collected from the previous period. They are mainly abstracting from international medical meetings, ongoing clinical studies, presentations by experts, clinical surveys, Google Scholar, and Post Market Clinical Follow-Up Study data.

Clinical Evaluation Plan is the first and the principal document to be prepared

Clinical Evaluation Report Annual Update

Many manufacturers assume that the Clinical Evaluation Report (CER) is done only once, but the reality is a big NO. It’s important to realize that the entire process including the report writing should be repeated on a regular basis.

 

Any significant changes which affect the initial collection of data should be recorded, and the CER be updated accordingly. The manufacturer should actively collect information from post-market experiences with their devices based on a PMS plan. 

 

Relevant data collected through the PMS should be used to update any relevant part of the CER. Updated CER to be submitted to Notified Body or competent authorities when requested or during annual surveillance audit.

 

Any relevant part of the CER should be updated using data collected through the PMS. When requested or during the annual surveillance audit, the updated CER will be submitted to the Notified Body or competent authorities every year

Frequently Asked Questions

EU MDR 2017/745, Article 61, Clinical Evaluation Report Contents

Based on the device's risk category, the Clinical Evaluation Report can be simple or quite extensive. The CER is a major portion of the technical file even though it is a stand-alone document and is required for all medical devices regardless of classification. 

 

It provides evidence that the device has undergone rigorous evaluation or, in many cases, compared to research done for other substantially equivalent devices already on the market. This includes data specific to the product in question, and any data relating to devices claimed as equivalent by the manufacturer.

 

It contains enough information to be read and understood by an independent party like a regulatory authority or a notified body. Hence, it provides sufficient details for understanding the search criteria adopted, available data, all assumptions made, and all conclusions reached. The general table of contents as per rev 4 is below.

 

  1. Summary
  2. Scope of the Clinical Evaluation
  3. General Details (Manufacturer Name & Address, Responsible Person)
  4. Device Details (Description, Name, Models, Variants, Intended Purpose, Risk Class, CE marking status, Contraindications, Warnings, Precautions, Identification of Changes from the previous version –if already in the market)

Review of Clinical Evaluation Report (CER) By Notified Body

The Notified Body has an important role in the assessment and verification of the Clinical Evaluation Report and supporting documentation provided by the manufacturers to support the demonstration of conformity of a product with the general safety and performance requirements of Annex I of MDR. The timing and the frequency of the notified body reviews will vary depending on:

 

 The device carries the risk.

  • How well-established the device is; and
  • The conformity assessment applied.

 

The NB's role is to conduct conformity assessments against GSPR requirements to evaluate clinical data; the requirements are explicitly stated in article 61 and MEDDEV 2.7.1 Rev 4. 

 

Notified Body to conduct conformity assessments and continuous monitoring by verifying manufacturer's presentation CER

 

  1. source of clinical data. 
  2. results of a clinical investigation, or from the literature of the subject device or an equivalent device demonstrate equivalency.
  3. justification must be given for not conducting a clinical investigation (class 111 devices)
  4. focus on the manufacturer's post-market surveillance plans.
  5. The PMCF study is another crucial source of clinical data. 

 

For all types of high-risk devices, a Post-market clinical follow-up should always be planned. Notified bodies are hesitant to accept a justification if not being conducted. The clinical investigation should always be considered and a justification for low-risk devices by adding pre-clinical testing instead of clinical data to support the device's safety.
