A Clinical Evaluation Report (CER) is a comprehensive document that is a cornerstone in the regulatory submission process for medical devices in many jurisdictions, including the European Union. It plays a crucial role in demonstrating the safety, performance, and clinical benefit of a medical device throughout its lifecycle. The CER is not just a requirement but a dynamic document that requires regular updates to reflect the ongoing assessment of the clinical evidence related to a medical device.

What is the Importance of a Clinical Evaluation Report?

A Clinical Evaluation Report is a critical component that regulatory authorities review to ensure that a medical device meets the required standards for market approval. The CER provides a detailed analysis of clinical data pertaining to a medical device, offering a clear picture of the device's clinical performance and its potential risks and benefits. This evaluation supports the claim that the medical device is safe and effective for its intended use. Furthermore, the CER is essential for maintaining the device's compliance with regulatory services requirements over time, as it must be updated to include new clinical data and reflect any changes in clinical practice or device usage.

What are the Roles and Functions of Clinical Evaluation Report?

Evidence Synthesis:One of the primary functions of the CER is to synthesize evidence from various clinical sources. This includes clinical trials , scientific literature, post-market surveillance data, and other relevant studies. The CER evaluates whether this body of evidence is sufficient to establish the safety and performance of the device.

Risk-Benefit Analysis:The CER performs a critical risk-benefit analysis, weighing the clinical benefits of the device against its potential risks. This analysis is fundamental in determining whether a device should be placed or kept on the market. It ensures that only those devices that provide a net clinical benefit to patients are approved for use.

Compliance and Regulatory Approval:The CER is pivotal in achieving and maintaining regulatory approval for a medical device . It demonstrates compliance with the relevant regulatory requirements, such as the Medical Device Regulation (MDR) in the European Union. By providing a thorough and up-to-date evaluation of the clinical evidence, the CER supports the ongoing certification of the device.

Post-Market Surveillance:Another crucial role of the CER is in post-market surveillance. The report must be regularly updated with new clinical data obtained from post-market sources, including registries, feedback from healthcare professionals, and adverse event reporting. This continuous evaluation helps to identify any emerging risks or issues with the device, ensuring that any necessary corrective actions can be taken promptly.

Stakeholder Communication:The CER serves as an important communication tool among stakeholders, including regulatory authorities, healthcare professionals, and patients. It provides a transparent account of the clinical evidence supporting the use of a device, helping stakeholders make informed decisions regarding its adoption and use.


The Clinical Evaluation Report is a fundamental document in the medical device regulatory landscape. It serves multiple roles and functions, from supporting regulatory approval to ensuring the ongoing safety and effectiveness of a device. The CER's importance lies in its ability to synthesize clinical evidence, conduct a thorough risk-benefit analysis, and facilitate compliance with regulatory standards. As such, the creation and maintenance of a comprehensive and up-to-date CER are essential for the success of a medical device throughout its lifecycle.
