• User Experience Optimization: Identifying and resolving usage-related issues to improve patient outcomes and overall user satisfaction.
• Data-Driven Innovation: Leveraging real-world feedback to enhance device features and functionality.
• Strengthened Clinical Evidence: Using real-world evidence to support clinical decision-making and validate device performance.
• Enhanced Safety and Performance: Continuously improving device safety and performance through ongoing monitoring and data analysis.

Under the EU MDR, PMCF is mandatory for all device classes, including legacy devices. Manufacturers must document their PMCF activities as part of their post-market surveillance (PMS) obligations. Failing to develop and execute a comprehensive PMCF plan can lead to non-compliance and potential regulatory sanctions.

Also, the FDA's post-market surveillance requirements are outlined under Section 522 of the Federal Food, Drug, and Cosmetic Act. PMCF is crucial for identifying potential safety and performance issues that may arise once a device is on the market. Manufacturers are expected to conduct PMCF studies to gather data that ensures their devices' ongoing safety and effectiveness. 

• Post-Market Surveillance (PMS) Plans: Develop comprehensive PMS plans that include PMCF activities to monitor device performance in real-world settings.
• Periodic Reporting: Submitting periodic reports to the FDA detailing PMCF findings helps assess the device's long-term safety and effectiveness.
• Corrective Actions: Implement necessary corrective and preventive actions based on PMCF data to address identified risks or issues.
