## Q\&A
PMCF reporting frequency depends on your device risk class, clinical evidence maturity, and notified body requirements. Typically, Class III and implantable devices require annual PMCF reports, while lower-risk devices may report biennially. Check your specific regulatory obligations and notified body agreements.
Immediately assess the clinical significance and implement appropriate risk controls. Update your risk management file, consider whether immediate regulatory notification is required, and plan additional PMCF activities to monitor the safety concern. Document all actions taken and their effectiveness.
Document all deviations from your original PMCF plan including reasons for changes, alternative approaches taken, and impact on study validity. Provide scientific justification for deviations and assess whether modified activities still address original clinical questions adequately.
Adequate PMCF data should address clinical questions identified in your PMCF plan, provide sufficient evidence to support continued clinical evaluation conclusions, and demonstrate ongoing safety and effectiveness. Data quality, sample size, and follow-up duration should be appropriate for your device risk profile and clinical claims.
Systematically incorporate PMCF data into your clinical evaluation report updates, assessing impact on benefit-risk analysis, equivalent device justifications, and state-of-the-art comparisons. Consider whether new evidence affects clinical claims, user populations, or risk assessments requiring regulatory notification.
Thoroughly investigate discrepancies between PMCF and pre-market data considering study design differences, population variations, and real-world factors. Update your clinical evaluation with new evidence, reassess benefit-risk balance, and consider whether design changes or labeling updates are needed.
