A Clinical Evaluation Report (CER) is a fundamental component of the technical documentation for medical devices and plays a critical role in demonstrating compliance with the European Medical Device Regulation (MDR). It provides scientific evidence that a medical device achieves its intended clinical performance while maintaining an acceptable benefit-risk profile. Developing a Clinical Evaluation Report can be challenging, requiring both regulatory expertise and scientific knowledge. In this article, you’ll learn about the MDR requirements for a Clinical Evaluation Report, the development process, and the professionals involved in creating a compliant CER.
What Is a Clinical Evaluation Report?
A Clinical Evaluation Report (CER) is a regulatory document that summarizes and documents the clinical evaluation of a medical device. Its purpose is to demonstrate, based on available clinical evidence, that the device achieves its intended clinical performance while meeting the MDR requirements for safety and an acceptable benefit-risk profile.
The development of a Clinical Evaluation Report is based on a systematic assessment of clinical evidence. This includes scientific literature, clinical investigation data, information collected through Post-Market Surveillance (PMS), and – where applicable – findings from Post-Market Clinical Follow-up (PMCF) activities.
For medical device manufacturers, the Clinical Evaluation Report is an essential part of the technical documentation and serves as a key element of the conformity assessment process.
What Are the MDR Requirements for a Clinical Evaluation Report?
The requirements for the clinical evaluation of a medical device are defined in Article 61 and Annex XIV of the European Medical Device Regulation (EU) 2017/745 (MDR). Manufacturers must demonstrate the clinical safety, clinical performance, and clinical benefit of their medical device through appropriate clinical evidence and document the results in a comprehensive Clinical Evaluation Report (CER).
An MDR-compliant Clinical Evaluation Report should address the following key elements:
- Clinical safety of the medical device
- Clinical performance in line with the device’s intended purpose
- Clinical benefit for the intended patient population
- Benefit-risk profile supported by robust clinical evidence
- Current state of the art based on scientific and clinical knowledge
- Continuous updates incorporating data from Post-Market Surveillance (PMS) and Post-Market Clinical Follow-up (PMCF)
Clinical evaluation is not a one-time activity. The Clinical Evaluation Report must be reviewed and updated throughout the entire product lifecycle whenever new clinical evidence becomes available, the device is modified, or additional PMS and PMCF data are generated.
What Does a Clinical Evaluation Report Include?
A Clinical Evaluation Report (CER) presents the clinical evaluation of a medical device in a structured, transparent, and MDR-compliant format. Its scope and level of detail depend on factors such as the device classification, intended purpose, product characteristics, and the availability of clinical evidence.
A Clinical Evaluation Report typically includes:
- Product description and intended purpose
- State-of-the-art assessment and comparison with relevant or similar medical devices
- A Clinical Evaluation Plan (CEP) outlining the evaluation methodology
- Systematic identification, appraisal, and analysis of clinical data from sources such as:
- Scientific literature
- Clinical investigations
- Equivalent or similar devices (where permitted by regulatory requirements)
- Post-Market Surveillance (PMS)
- Post-Market Clinical Follow-up (PMCF)
- Evaluation of clinical safety
- Assessment of clinical performance and clinical benefit
- Benefit-risk assessment
- Verification that sufficient clinical evidence supports the intended purpose
- Conclusions regarding compliance with the applicable General Safety and Performance Requirements (GSPRs)
- Recommendations for future activities, including PMS, PMCF, or Clinical Evaluation Report updates
All information included in a Clinical Evaluation Report must be scientifically sound, clearly documented, and aligned with the requirements of the European Medical Device Regulation (MDR).
How Is a Clinical Evaluation Report Developed?
Developing a Clinical Evaluation Report (CER) follows a structured and systematic process designed to demonstrate that a medical device is safe, performs as intended, and provides an acceptable benefit-risk profile based on clinical evidence.
The process typically includes the following steps:
- Define the evaluation scope based on the device’s intended purpose, target patient population, product characteristics, and clinical claims.
- Develop a Clinical Evaluation Plan (CEP) that outlines the methodology, data sources, and evaluation criteria.
- Identify and collect relevant clinical data through a systematic review of scientific literature, clinical investigations, and other applicable sources.
- Critically appraise and analyze the clinical evidence to assess the device’s safety, clinical performance, and benefit-risk profile.
- Document the findings in the Clinical Evaluation Report, including conclusions, identified evidence gaps, and recommendations for future activities.
Because clinical evaluation is an ongoing process, new information generated through Post-Market Surveillance (PMS) and Post-Market Clinical Follow-up (PMCF) should be continuously incorporated into the Clinical Evaluation Report throughout the product lifecycle.
How Do Clinical Evaluation Reports Differ Across Medical Device Classes?
The scope and depth of a Clinical Evaluation Report are determined not only by the device classification but also by its intended purpose, level of innovation, clinical claims, and overall risk profile. As a general rule, the greater the potential risk and the more complex or innovative the device, the more robust the required clinical evidence and evaluation.
For lower-risk devices, the clinical evaluation may be less extensive if supported by the intended purpose, risk profile, and available clinical data. For Class IIa, Class IIb, and Class III medical devices, manufacturers are typically expected to provide more comprehensive and higher-quality clinical evidence. Implantable devices and Class III devices generally require clinical investigations unless a specific exemption under the MDR applies.
Regardless of the device class, every Clinical Evaluation Report must clearly demonstrate that the medical device meets the applicable requirements for safety, clinical performance, and benefit-risk profile. The type and amount of clinical evidence required always depend on the specific characteristics and intended use of the device.
Which Professionals Are Involved in a Clinical Evaluation Report?
Preparing a Clinical Evaluation Report requires regulatory expertise, scientific knowledge, and a thorough understanding of medical devices. As a result, the clinical evaluation process is typically a collaborative effort involving specialists from multiple disciplines to ensure the report is scientifically robust and fully compliant with the MDR.
Key professionals involved include:
- Clinical Affairs Managers, who oversee the clinical evaluation process and assess clinical evidence.
- Regulatory Affairs Managers, who ensure that the Clinical Evaluation Report complies with MDR requirements and forms part of the technical documentation.
- Medical Writers, who organize and document clinical evidence in a clear, structured, and scientifically sound manner.
- Clinical Research Specialists, who contribute data and expertise from clinical investigations and other relevant sources.
- Clinical Evaluators or Medical Reviewers, who critically assess the quality and scientific validity of the clinical evidence.
- PMS/PMCF Specialists, who evaluate post-market data and incorporate new findings into the ongoing clinical evaluation.
- Risk Management Experts, who integrate the results of the clinical evaluation with the overall risk management process and assess the device’s benefit-risk profile.
A Clinical Evaluation Report is far more than a regulatory requirement – it is a cornerstone of the technical documentation for medical devices. Demonstrating compliance with the MDR requires a clinical evaluation that is based on robust clinical evidence, follows a scientifically sound methodology, and is thoroughly documented within the CER while being continuously updated throughout the product lifecycle.
Equally important are the professionals behind the process. Whether in Clinical Affairs, Regulatory Affairs, or Medical Writing, experienced specialists play a vital role in ensuring that Clinical Evaluation Reports are developed efficiently and in full compliance with regulatory requirements.
