    Second revision to MDCG 2023-3 Guidance document released

    On January 7th, 2025, the Medical Device Coordination Group (MDCG) released a new revision of its guidance document containing Questions and Answers on vigilance terms and concepts as outlined in the Regulation (EU) 2017/745 (MDR) and Regulation (EU) 2017/746 (IVDR). This second revision of MDCG 2023-3 contains minor clarifications when compared to the first revision.

    MDCG 2023-3 Rev. 2: Questions and Answers on vigilance terms and concepts as outlined in the Regulation (EU) 2017/745 and Regulation (EU) 2017/746.

    What is updated in MDCG 2023-3 Rev. 2:

    In explaining the difference between incidents and serious incidents, the reporting obligations of manufacturers are updated to align with the current gradual roll-out of Eudamed.

    Reference to ‘Eudamed vigilance module’ is corrected to ‘Eudamed Post-market surveillance and Vigilance module’.

    The review and commenting period for a competent authority upon receiving a draft Field Safety Notice is clarified to be 2 weekdays.

    What does it mean to you?

    MDCG 2023-3 Rev.2 is important for all MD and IVD manufacturers that place products on the EU market: they have to comply with the vigilance obligations from MDR respectively IVDR. Establishing a good understanding of vigilance terms and concepts is important to effectively implement the vigilance requirements under these Regulations.
