Clinical Evaluation Report (CER): Complete Guide for Medical Device Manufacturers

Clinical Evaluation Report (CER): Complete Guide for Medical Device Manufacturers

Why Clinical Evaluation Reports Matter

The CER is the cornerstone of regulatory compliance for medical devices in Europe. Here's why it's critical to your success.

Regulatory Requirement

The EU MDR 2017/745 mandates a comprehensive CER for all medical devices. It's not optional—it's the foundation of your regulatory submission.

Safety & Performance Evidence

The CER demonstrates that your device meets General Safety and Performance Requirements (GSPR) and provides clinical evidence of efficacy and safety.

Notified Body Approval

Notified bodies scrutinize CERs carefully. A well-structured, evidence-based report accelerates approval and reduces rejection risk.

Post-Market Surveillance

The CER must be updated throughout the device's lifecycle. Continuous data collection and analysis ensure ongoing compliance and market presence.

Competitive Advantage

A robust CER demonstrates clinical rigor and quality, building trust with healthcare providers, regulators, and end-users.

Risk Mitigation

A comprehensive CER identifies potential risks early, allowing you to implement mitigation strategies and avoid costly recalls or regulatory actions.

The 5 Essential Components of a Clinical Evaluation Report

A compliant CER follows a standardized structure defined by Annex XIV of the EU MDR. The depth and detail of each section depend on the device's risk classification, but the framework remains consistent. Below are the five core components every CER must include.

CER Clinical Evaluation Process & MDCG Guidelines

The Clinical Evaluation Process: Step by Step

Annex XIV of the EU MDR defines a structured process for clinical evaluation. While represented as sequential steps, real-world evaluation often involves feedback loops and iterative refinement.

1. Planning & Strategy

Define the clinical evaluation plan, identify relevant outcome parameters, establish benchmarks based on state-of-the-art (SOTA), and determine data requirements.

2. Data Collection

Gather pre-market clinical trial data, post-market surveillance data, literature reviews, and real-world evidence relevant to your device's safety and performance.

3. Data Appraisal

Critically evaluate the quality, relevance, and validity of collected data using systematic review methodology and predefined criteria.

4. Data Generation (if needed)

Conduct additional clinical studies or trials if existing data is insufficient to support safety and performance claims.

5. Data Analysis & Conclusions

Synthesize findings, assess safety and performance, identify risks, and draw evidence-based conclusions about device compliance with GSPR.

6. Post-Market Surveillance

Establish ongoing data collection mechanisms, periodic updates, and continuous monitoring to maintain CER validity throughout device lifecycle.

Key MDCG Guidelines for Clinical Evaluation

The Medical Device Coordination Group (MDCG) has published several guidance documents that clarify clinical evaluation requirements under the EU MDR. These guidelines are essential references for structuring your CER and ensuring compliance with regulatory expectations.

Guideline Focus Area Key Relevance to CER
MDCG 2020-5 Clinical Evaluation Core guidance on clinical evaluation planning, data collection, and appraisal methodologies for CER development.
MDCG 2020-6 Equivalence Defines requirements for demonstrating device equivalence to predicate devices in your CER.
MDCG 2021-6 Performance Evaluation Specifies performance evaluation requirements and how to present performance data in the CER.
MDCG 2019-9 (Rev. 1) SSCP & Clinical Data Guidance on Summary of Safety and Clinical Performance (SSCP) and integration of clinical data into regulatory submissions.
MDCG 2022-21 PMCF & Post-Market Requirements for post-market clinical follow-up (PMCF) and how to update the CER with post-market data.
MDCG 2023-3 Clinical Evaluation Updates Latest guidance on periodic CER updates and continuous clinical evaluation throughout device lifecycle.
MDCG 2020-13 Literature Review Systematic review methodology and literature search best practices for CER development.

Key Takeaways: CER Success Factors

Master these critical elements to ensure your CER meets notified body expectations and accelerates regulatory approval.

Robust Planning

A well-defined clinical evaluation plan is the foundation. Clearly specify outcome parameters, benchmarks, and data requirements upfront.

Systematic Review

Use rigorous, transparent methodology for literature searches and data appraisal. Document all search strategies and selection criteria.

Risk-Benefit Analysis

Clearly articulate the risk-benefit profile. Address potential risks honestly and explain mitigation strategies.

Evidence Quality

Prioritize high-quality clinical evidence. Pre-market trials are stronger than post-market data, but both are valuable.

GSPR Compliance

Explicitly demonstrate how your device meets all General Safety and Performance Requirements. Map evidence to each GSPR element.

Continuous Updates

Plan for post-market surveillance and periodic CER updates. The CER is a living document, not a one-time submission.
