CAPAs and Vigilance
CAPA Report
Document CAPA execution and effectiveness verification proving successful problem resolution.
Summary
A CAPA Report documents the execution and completion of corrective and preventive actions outlined in your CAPA Plan. You use this report to demonstrate that planned actions were implemented effectively, verify their success in resolving the original problem, and formally close the CAPA process.Why is the CAPA Report important?
CAPA Reports provide auditable evidence that your quality management system effectively resolves problems and prevents recurrence. They demonstrate regulatory compliance by showing systematic follow-through on corrective actions and verification of effectiveness. Without proper CAPA reporting, you cannot prove that identified problems were actually resolved, leaving your organization vulnerable to recurring issues and regulatory scrutiny. CAPA Reports also enable continuous improvement by documenting lessons learned and successful problem-solving approaches.Regulatory Context
Under 21 CFR Part 820.100 (Corrective and Preventive Action):
- Documentation of implementation must show corrective actions were taken
- Verification of effectiveness must be documented with objective evidence
- Records must be maintained for the life of the device plus additional time
- Management review must evaluate CAPA effectiveness and closure decisions
Special attention required for:
- CAPAs affecting design controls requiring design history file updates
- Software CAPAs requiring validation evidence for implemented fixes
- CAPAs resulting from FDA inspections or warning letters
- Integration with complaint handling and MDR reporting systems
Guide
Documenting Implementation
Record actual actions taken in detail, comparing them to the planned actions from your CAPA Plan. If you deviated from the original plan, explain why and justify the alternative approach. Include dates, responsible parties, and specific deliverables for each action. Document any challenges encountered during implementation and how they were overcome. This information helps improve future CAPA planning and demonstrates thorough execution of the corrective actions.Verification of Effectiveness
Provide objective evidence that your CAPA actions successfully resolved the original problem. This may include test results, audit findings, performance data, customer feedback, or other measurable indicators that demonstrate improvement. Compare before and after conditions to show the impact of your corrective actions. Use the same metrics that identified the original problem to demonstrate resolution and prevention of recurrence.Closure Decision
Evaluate completeness by confirming all planned actions were implemented and verification activities completed successfully. Review whether the root cause was adequately addressed and preventive measures are in place. Make closure decision based on objective evidence of effectiveness. If the CAPA cannot be closed, document remaining actions and timeline for completion. Only close CAPAs when you have confidence the problem is resolved.Integration with Quality System
Update related documents such as procedures, work instructions, training materials, or risk assessments based on CAPA findings. Ensure changes are properly controlled and communicated to affected personnel. Add to CAPA list for tracking and trend analysis. Update your management review data to include CAPA outcomes and lessons learned for continuous improvement planning.Example
Scenario: Following the CAPA Plan for software compatibility issues with glucose readings, you have implemented corrective actions including a software hotfix, Field Safety Notice, and enhanced testing procedures. After 90 days of monitoring, you need to document the results and determine if the CAPA can be closed.Example CAPA Report

Q&A
What should be done if planned CAPA actions prove ineffective?
What should be done if planned CAPA actions prove ineffective?
Document the ineffectiveness with objective evidence, analyze why the actions failed, and develop additional corrective measures. Don’t close the CAPA until effectiveness is verified. Consider whether the root cause analysis was adequate or if additional investigation is needed.
How long should you monitor CAPA effectiveness before closure?
How long should you monitor CAPA effectiveness before closure?
Monitor for a period appropriate to the problem and risk level. Simple procedural issues may require 30-60 days, while complex safety issues may need 6-12 months. The monitoring period should be long enough to demonstrate sustained improvement and catch any recurrence.
What evidence is required to verify CAPA effectiveness?
What evidence is required to verify CAPA effectiveness?
Provide objective, measurable evidence such as performance data, audit results, complaint rates, test results, or customer feedback. The evidence should directly relate to the original problem and demonstrate that both the immediate issue and root cause have been addressed.
Can CAPAs be closed if not all planned actions were completed?
Can CAPAs be closed if not all planned actions were completed?
CAPAs can be closed if the completed actions effectively resolve the problem and prevent recurrence, even if not all originally planned actions were implemented. However, you must justify why certain actions were not needed and provide evidence that the problem is resolved.
How should CAPA reports be integrated with management review?
How should CAPA reports be integrated with management review?
Include CAPA outcomes in management review data, focusing on effectiveness trends, resource requirements, and system improvements. Use CAPA results to identify opportunities for preventive action and continuous improvement of your quality management system.
