    Dear RAPS members,

    I would like to know what kind of software changes are considered significant under MDD and EU MDR.

    Also i have a question regarding the guidance document MDCG 2020-03.
    Flowchart C - Step C5 "presentation of data": if certain data (non-diagnostic features) was presented in the pictorial format in the previous software version is now displayed in a table format in the revised version will that fall under significant change?

    Appreciate, if you can share your thoughts on this matter.

    Thanks!

    Regards,

    For your first question, recognize that any device can be in one of three states:
    Full MDD
    MDD as modified by EU-MDR Article 120
    Full MDR

    Under MDD and EU-MDR, the Notified Body determines when a change is a significant change. Typically, the NB includes it in the contract.

    Under MDD as modified by EU-MDR Article 120 there is an MDCG guidance document that applies, 2020-03.

    For software, there are two types. For software in a device, do not evaluate the software change, but its impact on the device. For software as a medical device, SaMD, evaluate the change at the device level (which is the software level).

    For MDCG 2020-03 Flowchart C - Step C5 you first must decode the garbled data presented in the note. A new layout of the same data is a minor change. A new format of medical data is a significant change.

    I believe that changing the form of non-diagnostic information from a pictorial format to a table format falls under the note's description of a minor change.

    I recommend you also evaluate this change under the concepts of IEC 62366-1:2015, 4.1.3 to determine the key factors:
    The user perceives the information
    The user understands the information
    The information supports correct use

    The change in format may result in a new set of use errors.
