What is a Clinical Evaluation?

Clinical evaluation for medical devices is a systematic and ongoing process of collecting, analyzing, and assessing clinical data related to a medical device to determine its safety and performance throughout its lifecycle. It is a critical component of the regulatory framework for medical devices and is essential to ensure that these devices meet the necessary safety and efficacy requirements for their intended use.

Here are key aspects of clinical evaluation for medical devices:

  1. Purpose: Demonstrate device safety and performance.
  2. Data Sources: Gather data from trials, literature, and real-world use.
  3. Literature Review: Analyze relevant scientific literature.
  4. Clinical Trials: Conduct trials for specific data, when required.
  5. Risk Assessment: Identify, assess, and mitigate device risks.
  6. Benefit-Risk Assessment: Evaluate benefits vs. risks.
  7. Continuous Monitoring: Ongoing assessment throughout the device’s lifecycle.
  8. Regulatory Compliance: Comply with regional regulatory requirements.
  9. Clinical Evaluation Report (CER): Document findings and conclusions.
  10. Notified Body: Involvement in some regions (e.g., EU under MDR).

When Is Clinical Evaluation Undertaken?

Clinical evaluation is a continuous procedure that takes place throughout the life cycle of a medical device. It is first carried out during the development of a medical device to identify data that must be collected for regulatory purposes and will inform if a new device clinical investigation is required, as well as the outcomes that must be investigated. It is then done on a regular basis as new information about the medical device’s safety, clinical performance, and/or effectiveness becomes available during its usage. This data is input into the continuing risk management process (per ISO 14971:2007) and may result in revisions to the manufacturer’s risk assessment, clinical investigation materials, Instructions for Use, and post-market activities. 

What Is a Clinical Evaluation Report (CER)?

A Clinical Evaluation Report (CER) is a detailed document that systematically assesses the clinical data and evidence related to a medical device. It’s a vital part of regulatory submissions, especially in the EU. Key components include device information, intended use, data sources, risk assessment, benefit-risk analysis, evaluation plan, data analysis, post-market surveillance, and compliance with regulations. The CER demonstrates the device’s safety and performance and helps determine its eligibility for market approval or continued marketing.

A CER may contain clinical data from: 

  • Clinical investigation of the device under evaluation. 
  • Clinical investigation or other studies reported in the scientific literature for an equivalent device. 
  • Peer-reviewed scientific literature reporting on other clinical experiences of the device being evaluated or an equivalent device. 
  • Data from clinically relevant post-market surveillance (PMS) with a focus on post-market clinical follow-up (PMCF). 
Clinical Evaluation Reports for Medical Devices

The CER indicates that there is sufficient clinical evidence to validate the safety and performance of the device under consideration, including clinical benefits, when used as intended. 

Clinical Evaluation Reports are required for all medical devices in the EU and are part of the Technical Documentation required by the Medical Devices Regulation (EU) 2017/745 (MDR) (except for custom-made devices). Technical Documentation is required for a device to get CE marking, which is required to sell or distribute medical devices in the EU. Except for Class I (self-certified) devices, the Technical Documentation, including the CER, must be audited by a Notified Body.  

What Is the Process of Clinical Evaluation for Medical Devices?

The process of clinical evaluation for medical devices involves a systematic and comprehensive assessment of the safety and performance of a medical device through the analysis of clinical data. This process is crucial to ensure that the device is safe and effective for its intended use, and it plays a significant role in obtaining regulatory approval or maintaining compliance throughout the device’s lifecycle. Here’s an overview of the general steps involved in the clinical evaluation process:   

  1. Define the Clinical Evaluation Plan (CEP): The process begins by outlining the clinical evaluation plan. This plan specifies the scope, objectives, methodology, and sources of clinical data to be used. It also defines the criteria for the acceptance of clinical evidence.  
  1. Identify Relevant Clinical Data: Gathering clinical data involves identifying relevant clinical studies, literature, and other sources of information that provide data on the device’s safety and performance. This can include preclinical studies, similar device data, clinical investigations, and post-market surveillance reports.  
  1. Collect and Review Clinical Data: Collect all relevant clinical data from various sources. Data may include clinical trial results, adverse event reports, post-market surveillance data, scientific literature, and competitor data. It’s important to ensure the quality and reliability of the collected data.  
  1. Appraise the Clinical Data: Assess the quality and relevance of the collected clinical data. Evaluate the methodologies used in clinical studies, patient populations, endpoints, statistical analyses, and any potential biases. This step helps determine the credibility of the data and its applicability to the device in question.  
  1. Analyze Safety and Performance: Analyze the clinical data to determine the safety and performance of the medical device. Compare the device’s performance against its intended purpose and the current state of medical knowledge.  
  1. Identify and Evaluate Risks: Identify potential risks associated with the device’s use. Evaluate whether the benefits outweigh the risks for the intended patient population and the device’s intended use.  
  1. Clinical Evaluation Report (CER) Compilation: Compile all the findings, analyses, and conclusions into a comprehensive clinical evaluation report (CER). The CER should provide a clear overview of the clinical evidence supporting the device’s safety and performance.  
  1. Clinical Evaluation Report Review: Internal and, if applicable, external experts should review the CER for accuracy, validity, and completeness. Regulatory bodies may also review the CER during the device’s approval or post-market surveillance processes.  
  1. Update and Continuous Monitoring: Clinical evaluation is an ongoing process. Manufacturers should continuously monitor the performance and safety of their devices and update the clinical evaluation as new data becomes available.  
  1. Submission and Approval: If required by the regulatory authority, submit the clinical evaluation report along with the device registration or approval application. Regulatory bodies will review the report to ensure that the device meets the necessary safety and performance standards.  

It’s important to note that the specific requirements and procedures for clinical evaluation can vary depending on the regulatory framework of the region or country where the device will be marketed. Manufacturers should follow the guidelines and regulations provided by the relevant regulatory authority.
