Medical devices - Guidance on the application of ISO 14971 - Part 2: Machine learning in artificial intelligence (ISO/DTS 24971-2:2025)

This document provides guidance on how to apply the risk management process of ISO 14971:2019 to ML-enabled medical devices (MLMD). This document is intended to be used in conjunction with ISO 14971 and does not alter the risk management requirements specified in ISO 14971. 
This document addresses risks specific to machine learning (ML). Those risks can be related to topics such as data management, feature extraction, unwanted bias, information security, training the ML model by an ML algorithm, evaluation and testing of the trained ML model. See Figure 1 for an overview of the relevant terms and their relationship. See Annex A for an explanation of bias.
It is recognized that the ML model can require retraining after a period of use to redefine its parameters. An ML model can learn continuously from patient data and modify their parameters accordingly. The description “continuous(ly) learning” is used throughout this document; the term “adaptive” is sometimes used in other documents. This document also provides examples and suggests strategies for eliminating or controlling these ML-related risks.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)

Introduction
Artificial intelligence (AI) is rapidly evolving and can bring advantages to healthcare. These advantages can
be related to improved benefits for the patient, improved efficiencies in clinical workflows and improvement
in the management of healthcare itself. However, the implementation of new technologies such as AI can also
present new risks and can, for example, jeopardize patient safety, affect privacy and security, influence user
actions, undermine trust in healthcare or adversely affect the management of healthcare.
[16]
The safety and effectiveness of AI in medical devices was explored in an AAMI-BSI document , which
identified three ways in which AI-based medical devices differed from “traditional” (non-AI) medical devices:
a) Training. These medical devices can process large amounts of data and learn from these data to improve
their results. Thus, they can have positive effects on patient health within the scope of the intended use
of the medical device.
b) Level of autonomy. These medical devices can have the ability to generate different treatment options,
select the best option based on a trained model and execute the selected option (see for example
[8]
IEC/TR 60601-4-1 ). These steps can be performed with reduced or even without direct user action,
but only with human oversight.
