    What standard is applicable for medical device algorithms? Do manufacturers use IEC 62304, software lifecycle, to develop them or is there another standard or regulation?

    62304 is appropriate for implementing an algorithm in software.

    For developing the algorithm in the first place, there may be a disease-specific standard to consider as input, but usually it's plain research and development, science and mathematics.

    Unless you're using tools like neural net training, in which case there are some standards for that.

    There are specific standards that can be applied to the design, development, and validation of medical device algorithms. The most commonly used standard is IEC 62304:2006, which provides guidance on software life cycle processes for medical device software. In addition to IEC 62304, there are other standards and guidelines that can be applied to the development of medical device algorithms, depending on their intended use. For example, ISO 14971 provides guidance on risk management for medical devices, including software and algorithms, and the FDA has issued guidance documents on the development and use of artificial intelligence and machine learning algorithms in medical devices.

    While not a standard, FDA, Heath Canada, and MHRA have jointly put out a Good Machine Learning Practice guidance that outlines guiding principals. It's brief but can be very useful in planning the development, validation, and clinical testing of medical device algorithms.

    In addition to IEC 62304, my team has also found IEE 1016 useful, though neither standard has a whole lot to directly say.

    Depending on what your algorithm is meant to accomplish. 
    There is lots of useful information in RF Quarterly and other posts. Enjoy your reading:

    Anon,

    Just note, IEC 62304 is a standard for the development of software over the life cycle of the product - it does not get into the detail of developing, testing, or managing specifically an algorithm.  For development of an algorithm especially describing the architecture and function, and including testing of algorithms (training in AI/ML or inputting clinical data) there is not a specific standard or regulation, but there are quite a few useful papers on this subject.  The US FDA has initially published some high-level guidance and position papers on AI/ML which might be helpful, but this is an evolving area.

    AAMI has published a Consensus Report on AI and ML, AAMI TIR 34971:2022 which deals with risk management of AI/ML.  The document is being proposed by AAMI and BSI as input to development of an ISO Technical Report, which would be numbered as ISO TR 34971 if the proposal is accepted.  The CR version is available for purchase at AAMI.org

    ISO 62304 and ISO82304 are the base for SaMD, but if we focus more specifically on ML/ AI algorithms, a lot of standards are under development or already released:

    ISO 23894:2023
    ISO/IEC TR 24027:2021
    ISO/IEC TR 29119-11:2020
    ISO/IEC TR 22989:2022
    AAMI CR34971:2022
    DIN SPEC 92001-1:2019
    DIN SPEC 92001-2:2020


    There was an interesting post on Linkedin on this subject:
    https://www.linkedin.com/posts/antoniobartolozzi_ai-standards-ai-activity-7032971067300229120-WK6o?utm_source=share&utm_medium=member_desktop

    I would add to the list the upcoming ISO/IEC 42001 on AI Management System and ISO/IEC DIS 5338 on AI system life cycle process.

    And you would also need to consider all the ones linked to cybersecurity....
