​
Summary

You must establish systematic procedures to monitor your medical device’s safety and performance after market release through ongoing data collection, analysis, and reporting that identifies emerging risks and confirms expected device behavior. Post-market surveillance ensures continuous patient safety while meeting regulatory obligations for ongoing compliance and risk management throughout the commercial device lifecycle.

​
Regulatory Context

Under 21 CFR Part 820 (Quality System Regulation) and 21 CFR Part 803 (Medical Device Reporting), you must implement:
  • Post-market surveillance system per Section 820.100 for corrective and preventive actions
  • Medical Device Reporting (MDR) mandatory for deaths, serious injuries, and malfunctions per Part 803
  • Complaint handling procedures per Section 820.198 for systematic data collection
  • Periodic reporting requirements for specific device types and conditions
  • Unique Device Identification (UDI) integration for traceability per 21 CFR Part 830
Special attention required for:
  • Software medical devices requiring cybersecurity monitoring per FDA guidance
  • Class III devices with enhanced post-market study requirements
  • FDA-mandated post-market studies as conditions of device approval
  • Real-world performance monitoring for AI/ML-enabled devices per FDA guidance

​
Overview

Post-market surveillance represents your ongoing commitment to patient safety and regulatory compliance by establishing systematic monitoring procedures that detect emerging risks, validate pre-market assumptions, and ensure continued device safety throughout its commercial lifecycle. This comprehensive surveillance framework transforms passive compliance into proactive safety management that protects patients while supporting business sustainability through early identification and resolution of potential issues. Post-Market Surveillance Planning establishes the comprehensive framework for ongoing device monitoring by defining data collection sources, analysis methodologies, reporting procedures, and organizational responsibilities. Your surveillance plan must specify how you will monitor vigilance databases, user complaints, literature sources, and field experience data while establishing statistical methods for trend analysis and risk assessment procedures. Planning activities require integration with your risk management system to ensure that post-market findings trigger appropriate risk assessment updates and corrective actions when necessary. Vigilance Database Monitoring provides systematic access to global adverse event data that may indicate emerging safety issues or unexpected device behaviors not apparent during pre-market testing. This monitoring requires regular searches of FDA MAUDE, European vigilance databases, and other international reporting systems using device-specific keywords and classification codes. Effective vigilance monitoring enables early detection of safety signals while providing competitive intelligence about similar devices and industry-wide issues that may affect your device’s risk profile. Complaint Management and Analysis transforms user feedback into actionable safety intelligence by systematically collecting, categorizing, and analyzing complaints related to device performance, safety concerns, and user difficulties. Your complaint management system must distinguish between general customer service issues and medical device-related complaints that require regulatory attention while maintaining complete documentation for trending analysis and regulatory reporting. Complaint analysis provides real-world insights into device performance and user interaction that may reveal risks not identified during controlled testing. Literature and Registry Monitoring ensures awareness of published research, clinical studies, and registry data that may contain relevant safety information about your device or similar technologies. This monitoring requires systematic review of medical literature, conference proceedings, and device registries while establishing procedures for evaluating the relevance and impact of new findings on your device’s safety profile. Literature monitoring provides scientific context for post-market findings and may identify emerging clinical evidence that affects your device’s benefit-risk assessment. Statistical Analysis and Trending transforms raw surveillance data into meaningful safety intelligence through appropriate statistical methods that can detect significant changes in incident frequency or severity. Your analysis procedures must include complaint rate calculations, trend analysis using methods such as the Mann-Kendall test, and risk assessment integration that determines when post-market findings require immediate action versus inclusion in periodic reports. Statistical rigor ensures that surveillance activities provide reliable safety signals while preventing overreaction to normal variation in reported events. Reporting and Regulatory Communication ensures timely, accurate submission of required post-market surveillance reports while maintaining effective communication with regulatory authorities about emerging safety issues. Your reporting procedures must address immediate notification requirements for serious incidents, periodic surveillance report submission, and proactive communication about safety signals or corrective actions. Effective regulatory communication builds trust with authorities while ensuring compliance with evolving surveillance requirements. Corrective and Preventive Action Integration links surveillance findings to systematic improvement processes that address identified risks while preventing recurrence of safety issues. This integration requires clear escalation procedures for surveillance findings that exceed acceptable risk levels, systematic root cause analysis of identified issues, and verification that corrective actions effectively address underlying problems. CAPA integration ensures that surveillance activities result in continuous safety improvement rather than passive monitoring. International Surveillance Coordination addresses the complexity of monitoring device performance across multiple markets with different regulatory requirements, reporting systems, and cultural contexts. Coordination activities include establishing consistent surveillance procedures across markets, integrating diverse data sources, and ensuring that local findings are appropriately shared across your global operations. International coordination prevents surveillance gaps while ensuring that safety signals detected in one market are properly evaluated for global implications. Technology and Data Management supports surveillance activities through robust systems that enable efficient data collection, analysis, and reporting while maintaining data integrity and regulatory compliance. Technology requirements include database systems for complaint and incident tracking, analytical tools for statistical trending, and integration platforms that combine diverse data sources into comprehensive surveillance insights. Effective data management enables scalable surveillance operations while supporting regulatory requirements for data retention and audit trails. Your post-market surveillance activities must demonstrate continuous improvement in device safety and performance while providing regulatory authorities with transparent, systematic evidence of ongoing safety monitoring. Well-executed surveillance programs enable early detection and resolution of safety issues, reduce liability exposure, and support successful long-term market presence by maintaining public confidence in device safety through proactive risk management and transparent regulatory compliance.
