EU MDR Audit Trends 2026: What Notified Bodies Are Focusing On
As the EU Medical Device Regulation matures into its full enforcement phase, the pattern of Notified Body audit findings is becoming clearer. Across 2025 and into 2026, three recurring themes have emerged in audit reports and industry feedback: clinical evidence traceability, Post-Market Surveillance system robustness, and the completeness of economic operator documentation chains.
For manufacturers who entered the MDR pathway under transition provisions, the expectation has now shifted significantly. Initial certification audits gave many companies a degree of latitude; renewal and surveillance audits are being conducted at a considerably higher standard. Notified Bodies are spending more time on PMS plans and their connection to the clinical evaluation update cycle — a gap that many manufacturers underestimated during initial submission.
The second major trend is technical documentation traceability. Auditors are specifically looking at whether risk management outputs are consistently reflected across the technical file — from the risk management report through to design verification, post-market data, and labelling decisions. Disconnected documentation structures that were accepted during early certification are now generating non-conformances.
