Clinical Evaluation Report for Medical Devices: What It Is and How to Prepare One
If you make medical devices and want to sell them in Europe, you’ll need a clinical evaluation report (CER). It’s the document where you show, with real evidence, that your device is safe and does what you say it does. A solid CER helps you get regulatory approval, and it keeps you compliant long after the device reaches the market.
So, What Exactly Is a CER?
A CER pulls together clinical data from several places: published scientific literature, your own clinical investigations, and information on equivalent devices already in use. Under EU MDR 2017/745, every manufacturer has to carry out a clinical evaluation. The CER is where you write down how you did it and what you found.
What Goes Into Preparing One
Writing a CER is mostly about gathering evidence, checking its quality, and being honest about the risks. In practice, that means:
- Collecting clinical data: Draw on clinical investigations, scientific publications, and post-market surveillance.
- Reviewing the literature: Look at what published research says about how safe and effective your device (or similar ones) really is.
- Weighing risks against benefits: Ask whether the clinical benefits clearly outweigh any risks to patients.
- Judging the evidence itself: Not all data is equal, so assess how relevant, high-quality, and reliable each source is.
How a CER Is Usually Structured
Most reports follow a similar flow:
- Device description and intended purpose
- Clinical background and state of the art
- Evaluation methodology
- Identification and appraisal of clinical data
- Analysis of the clinical evidence
- Risk-benefit assessment and conclusions
Importance of Regulatory Compliance
A well-prepared CER does more than tick a regulatory box. It strengthens your technical documentation and gives regulators and notified bodies confidence in your device. It also needs regular attention. Whenever new clinical evidence or post-market surveillance data comes in, the report should be updated to reflect it.
