Clinical Evaluation
Clinical Evaluation Report
Document systematic clinical evidence analysis supporting regulatory approval and market compliance.
Summary
A clinical evaluation report documents your systematic analysis of clinical evidence demonstrating your device’s safety and clinical performance. This comprehensive document presents your literature review findings, equivalence analysis, and clinical data evaluation to support regulatory approval and ongoing market compliance.Why is Clinical Evaluation Report important?
The clinical evaluation report serves as primary evidence for regulatory authorities that your device meets safety and performance requirements under EU MDR Article 61 and FDA regulations. This document directly supports your CE marking application, 510(k) submission, or other regulatory pathways by demonstrating clinical evidence adequacy. Regulators use this report to assess whether your device achieves its intended clinical benefits while maintaining an acceptable benefit-risk ratio. The report also establishes the foundation for post-market clinical follow-up activities and provides evidence for General Safety and Performance Requirements (GSPR) compliance. Without a robust clinical evaluation report, you cannot demonstrate regulatory compliance or justify market access.Regulatory Context
Under 21 CFR Part 820 and FDA guidance documents:
- Clinical evaluation report supports 510(k) substantial equivalence determination
- Must demonstrate safety and effectiveness through appropriate clinical evidence
- Predicate device comparison requires detailed clinical performance analysis
- Literature review and clinical data analysis must follow FDA guidance standards
Special attention required for:
- Software medical devices requiring algorithm validation data
- Novel devices without adequate predicate devices requiring clinical studies
- Class III devices requiring Premarket Approval (PMA) with clinical trial data
- AI/ML devices requiring real-world performance validation
Guide
Your clinical evaluation report must present a comprehensive and objective analysis of all available clinical evidence supporting your device’s safety and clinical performance. The report serves as the definitive document demonstrating regulatory compliance and clinical adequacy.Device Information and Clinical Claims
Begin with detailed device characterization including technical specifications, intended purpose, patient population, and use environment. Document all clinical claims and benefits your device provides, ensuring alignment with your intended use statement. Present your device classification and regulatory pathway, as these determine the evidence standards your report must meet.Literature Review and Analysis
Present your systematic literature search results following your clinical evaluation plan methodology. Document search strategies, databases queried, and inclusion/exclusion criteria applied. Analyze retrieved literature using structured appraisal criteria, categorizing evidence by relevance to your device, equivalent devices, and state of the art. Present evidence tables summarizing key findings from relevant publications, including study design, patient populations, clinical outcomes, and relevance scores.Equivalence Demonstration
If claiming equivalence, provide detailed technical, biological, and clinical comparison between your device and the equivalent device. Present comparison tables addressing all relevant characteristics per MDCG 2020-5 requirements. Justify any differences and demonstrate they don’t affect clinical safety or performance. Document the equivalent device’s clinical history and regulatory status to support your equivalence claim.State of the Art Analysis
Analyze the current clinical landscape for your device’s intended use, including existing treatment options, clinical standards, and competing technologies. Compare your device’s performance against established benchmarks and demonstrate how it fits within or advances current clinical practice. This analysis supports your benefit-risk assessment and clinical positioning.Pre-Clinical and Clinical Data Integration
Integrate relevant verification and validation data, usability testing results, and any clinical investigation findings. Present how pre-clinical testing supports your clinical claims and addresses identified risks. Document any biocompatibility, electrical safety, or performance testing results that contribute to clinical evidence.Post-Market Data Analysis
Present findings from vigilance database searches and any available post-market surveillance data. Analyze safety signals, adverse events, and performance issues reported for your device, equivalent devices, and similar technologies. Demonstrate how this data informs your benefit-risk assessment and clinical conclusions.Benefit-Risk Analysis
Conduct a comprehensive benefit-risk assessment weighing your device’s clinical benefits against identified risks. Present evidence supporting each claimed benefit and demonstrate risk acceptability based on clinical evidence. Address how your device’s benefit-risk profile compares to existing treatment options and meets GSPR requirements.Clinical Conclusions and GSPR Compliance
Present clear clinical conclusions regarding your device’s safety and clinical performance based on all evaluated evidence. Demonstrate compliance with relevant GSPRs, particularly GSPR 1, 2, 6, and 8. Document any evidence gaps and plans for addressing them through post-market activities.Post-Market Clinical Follow-Up Planning
Outline your PMCF strategy based on clinical evaluation findings, including specific clinical questions requiring ongoing monitoring. Plan data collection methods, timelines, and success criteria for post-market clinical activities.Example

Q&A
What is the purpose of a clinical evaluation plan and report?
What is the purpose of a clinical evaluation plan and report?
The clinical evaluation plan establishes your methodology for gathering clinical evidence, while the report documents your analysis and conclusions. Together, they demonstrate that your device meets regulatory requirements by showing adequate clinical evidence for safety and performance. The report serves as primary evidence for regulatory submissions and ongoing compliance monitoring.
How much clinical evidence do I need for my device?
How much clinical evidence do I need for my device?
Evidence requirements depend on your device’s risk classification, novelty, and intended use. Class I devices typically need minimal clinical evidence, while Class III devices require extensive clinical data including investigations. Most Class IIa software devices can rely on literature review and equivalence demonstration. Consult MDCG 2020-6 evidence level requirements for your specific device type.
Can I use literature from devices that aren't exactly the same as mine?
Can I use literature from devices that aren't exactly the same as mine?
Yes, you can use literature from similar devices as supportive evidence for state-of-the-art analysis. However, for equivalence claims, you need a specific equivalent device that closely matches your technical, biological, and clinical characteristics. Literature from the broader clinical field helps establish clinical background and benchmarks but cannot substitute for device-specific evidence.
What if my literature search doesn't find enough relevant studies?
What if my literature search doesn't find enough relevant studies?
Limited literature is common for novel devices or niche applications. Document your search strategy thoroughly and justify why available evidence is sufficient for your device’s risk level. Consider expanding search terms, including older studies, or looking at related clinical areas. For higher-risk devices with insufficient literature, you may need to conduct clinical investigations.
How do I demonstrate equivalence if my device has some different features?
How do I demonstrate equivalence if my device has some different features?
Focus on demonstrating that core clinical functionality remains equivalent while additional features don’t introduce new risks. Document technical, biological, and clinical similarities systematically. Justify any differences by showing they don’t affect safety or clinical performance. Enhanced features that improve usability without changing core function typically support rather than undermine equivalence claims.
When do I need to update my clinical evaluation report?
When do I need to update my clinical evaluation report?
Update your report when new clinical evidence becomes available, safety signals emerge, or your device changes significantly. Plan regular updates based on your PMCF activities and literature monitoring. Major updates may be required for significant software changes, new indications, or regulatory guidance updates. Maintain version control and document all changes in revision history.
