Medical Device Audits - 9 Tips to Perform Them in 2025
Apr 30, 2025
Medical device audits are more than a regulatory checkpoint.
In 2025, they are a strategic necessity, protecting patient safety, boosting product credibility, and supporting market access worldwide.
One weak audit can delay approvals, trigger costly recalls, or even result in the loss of certification.
That’s why mastering the medical device audits is crucial for manufacturers, suppliers, and distributors operating in the medical device industry.
Let’s break it down.
Overview of Medical Device Audits in 2025
Medical device compliance audits involve a systematic review of a company’s operations, documentation, processes, and products to confirm compliance with major regulatory requirements like the MDR (Medical Device Regulation), FDA 21 CFR Part 820, ISO 13485:2016, and other international standards.
In 2025, audit expectations are rising, with a stronger emphasis on risk management, traceability, clinical evaluation data, and maintaining continuous compliance throughout the device lifecycle, not just at launch.

Its AI compliance agents continuously evaluate conformity, generate smart checklists, and identify gaps early, helping you conduct thorough self-assessments with greater accuracy and efficiency.
2. Engage and Train Your Team Early
Audits are a team effort, not just a task for the quality department.
➸ Regulatory Basis:
FDA QSR (21 CFR 820.25) mandates adequate training of personnel.
➸ Practical Example:
Before an EU MDR audit, a company hosts cross-departmental training workshops on how to handle auditor questions and present technical documentation.
➸ Implementation Tips:
Conduct audit readiness training sessions for all relevant employees.
Assign audit roles (such as spokesperson, runners, and document controllers) in advance.
Rehearse common scenarios to boost confidence and accuracy.
3. Develop a Clear and Detailed Audit Plan
Without a roadmap, audits can quickly become chaotic.
➸ Regulatory Basis:
ISO 19011:2018 guides the planning of internal audits for management systems.
➸ Practical Example:
A surgical device company creates a detailed audit plan that outlines the scope, timelines, locations, processes to be audited, and the responsibilities of the audit team.

➸ Implementation Tips:
Align the audit plan with risk priority and focus on higher-risk processes first.
Communicate the plan to all involved teams well in advance.
Include contingency plans for missing documents or in the event of key staff absences.
4. Prepare and Organize Documentation and Evidence
Disorganization wastes valuable audit time and erodes trust.
➸ Regulatory Basis:
ISO 13485:2016 emphasizes the need for documented evidence to demonstrate compliance.
➸ Practical Example:
An orthopedic implant manufacturer sets up an “audit room” with hard copies of all requested procedures, validation protocols, design history files, and training records.
➸ Implementation Tips:
Use digital folders that mirror the structure of your quality management system.
Double-check controlled documents for version control and approvals.
Prepare a list of documents that are likely to be requested and practice retrieving them quickly.

5. Maintain Professionalism and Cooperation During the Audit
Attitude matters just as much as technical compliance.
➸ Regulatory Basis:
FDA guidance notes that cooperation can influence the overall tone and findings of an inspection.
➸ Practical Example:
During an unannounced notified body audit, a medical device company designates a point of contact to maintain a calm, respectful dialogue throughout the visit.
➸ Implementation Tips:
Greet auditors professionally; make them feel welcome.
Listen carefully and answer questions clearly and truthfully.
Avoid volunteering extra information not directly requested.
6. Use Internal Audits to Identify and Address Issues Proactively
Catch problems yourself before the regulators do.
➸ Regulatory Basis:
EU MDR (Annex IX) emphasizes self-monitoring and internal conformity checks.
➸ Practical Example:
A diagnostic device company uncovers an obsolete risk assessment document during a quarterly internal audit and updates it before their notified body inspection.
➸ Implementation Tips:
Treat internal audits as full rehearsals, not casual walkthroughs.
Use external consultants periodically for fresh perspectives.
Track corrective actions and verify effectiveness over time.
7. Foster a Culture of Continuous Improvement and Compliance
Compliance is a living process, not a one-time event.
➸ Regulatory Basis:
ISO 13485 requires ongoing improvement of the quality management system.
➸ Practical Example:
A start-up building wearable medical monitors holds monthly compliance meetings to review audit findings, new regulatory updates, and ideas for improvement.
