Clinical evaluation is the cornerstone of the European Union Medical Device Regulation (MDR). It ensures that medical devices meet the necessary safety and performance requirements before they can be placed on the European market.
The MDR places more stringent demands on clinical evaluation than its predecessor, the Medical Device Directive (MDD), requiring manufacturers to provide comprehensive clinical evidence to demonstrate that their devices are safe and effective.
In this blog post, we’ll provide a comprehensive guide to conducting a successful clinical evaluation under the MDR. We’ll cover the key requirements, the process of clinical evaluation, and practical advice to help manufacturers navigate this critical aspect of MDR compliance.

What is Clinical Evaluation?
Clinical evaluation refers to the systematic process of assessing and analyzing clinical data to determine whether a medical device is safe and performs as intended. The goal of clinical evaluation is to gather sufficient clinical evidence to support the device’s intended use, risk profile, and regulatory compliance.
The MDR places a much greater emphasis on clinical evidence compared to the MDD. Manufacturers must not only provide clinical data at the time of market approval but also continuously collect and analyze data throughout the device lifecycle.
This means that clinical evaluation is not a one-time task but an ongoing process that must be updated regularly.
Key Requirements for Clinical Evaluation Under the MDR
The MDR outlines specific requirements for clinical evaluation that manufacturers must follow:
Clinical Evaluation Plan (CEP)
A comprehensive clinical evaluation plan (CEP) is required under the MDR. This plan outlines the objectives, methodology, and timeline for the clinical evaluation process. It also specifies the types of clinical data that will be used and identifies the criteria for assessing the device’s safety and performance. Manufacturers must ensure that the CEP aligns with the intended use of the device and the relevant regulatory requirements.
Literature Review and Clinical Data
If the available literature does not provide sufficient evidence to support the device’s safety and performance, manufacturers may need to conduct a clinical investigation. This investigation involves gathering primary clinical data through trials or studies, usually on human subjects, to evaluate the device’s safety, performance, and intended use.
Clinical Investigation (if required)
If the available literature does not provide sufficient evidence to support the device’s safety and performance, manufacturers may need to conduct a clinical investigation. This investigation involves gathering primary clinical data through trials or studies, usually on human subjects, to evaluate the device’s safety, performance, and intended use.
Analysis of Clinical Data
Once clinical data has been gathered, manufacturers must analyze it to assess the safety and performance of the device. This involves comparing the data against the intended use, risk profile, and any applicable regulatory standards. Manufacturers must ensure that the clinical evidence is robust and supports the device’s claims regarding safety and performance.
The Clinical Evaluation Process
The process of clinical evaluation under the MDR typically involves several steps:
- Preparation of the Clinical Evaluation Plan
The first step in the clinical evaluation process is preparing a comprehensive clinical evaluation plan (CEP). This plan outlines the clinical evaluation process and ensures that all necessary steps are taken to gather and assess relevant clinical data. - Literature Review and Data Collection
The next step is conducting a thorough literature review to gather existing clinical data related to the device. This data can come from published studies, clinical trials, or real-world experience with similar devices. If the literature does not provide sufficient evidence, the manufacturer may need to conduct a clinical investigation to gather primary clinical data. - Clinical Investigation (if needed)
If additional clinical data is required, manufacturers must conduct a clinical investigation. This involves testing the device on human subjects in a controlled environment and collecting data on its performance, safety, and efficacy. The clinical investigation must comply with ethical standards and regulatory requirements. - Analysis of Data
After collecting the necessary data, manufacturers must analyze the clinical data to evaluate the device’s safety and performance. This analysis should be comprehensive, taking into account the device’s risk profile, intended use, and regulatory standards. The analysis should be detailed enough to justify the device’s market approval. - Clinical Evaluation Report (CER)
The final step in the clinical evaluation process is the preparation of a clinical evaluation report (CER). The CER is a comprehensive document that summarizes the clinical data and provides an analysis of the device’s safety and performance. This report must be submitted to the Notified Body as part of the regulatory approval process.
Best Practices for Clinical Evaluation
Manufacturers should gather as much relevant clinical data as possible from a variety of sources, including literature reviews, clinical trials, and post-market data. The data should be robust and demonstrate that the device is safe and performs as intended.
Clinical evaluation is an ongoing process. Manufacturers must update the CER regularly based on new clinical data, including post-market surveillance findings and any new clinical trials or studies. An up-to-date CER ensures that the device remains compliant with MDR requirements.
Given the complexity of clinical evaluation under the MDR, manufacturers should work with regulatory experts who are familiar with the clinical evaluation process. These experts can guide manufacturers through the process, help identify potential issues, and ensure that the evaluation meets all necessary regulatory requirements.
In summary, clinical evaluation is an essential component of the MDR compliance process, and it plays a critical role in ensuring that medical devices are safe and effective. By following the MDR’s guidelines for clinical evaluation and maintaining a robust system for collecting and analyzing clinical data, manufacturers can ensure compliance, improve patient safety, and streamline the regulatory approval process.
