Overview
IEC/TR 60601-4-1:2017 provides guidance and interpretation for medical electrical equipment (MEE) and medical electrical systems (MES) employing a degree of autonomy (DOA). Developed through collaboration between the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO), this technical report supports manufacturers and standard writers in applying detailed risk management and usability engineering processes for autonomous and semi-autonomous medical devices and systems.
The report is aimed at clarifying terminology, providing a framework for classifying the degree of autonomy, and supporting the alignment of emerging standards for autonomous medical technologies. This is particularly relevant for medical robots and other advanced systems increasingly integrated within modern healthcare environments.
Key Topics
- Degree of Autonomy (DOA): The report offers definitions and a taxonomy for DOA, outlining the spectrum from fully manual to highly autonomous medical electrical systems.
- Risk Management: Detailed guidance is provided on risk management processes specific to MEE and MES with autonomy, in compliance with IEC 60601-1 and aligned with standards such as ISO 14971.
- Usability Engineering: Recommendations on integrating usability engineering principles, with a focus on operator awareness, reaction time, and error detectability in autonomous or semi-autonomous systems.
- Safety and Performance: Considerations for basic safety and essential performance of autonomous medical devices, including how DOA impacts clinical function and patient safety throughout the product lifecycle.
- Terminology Consistency: Guidance on consistent use of concepts like ‘autonomy’ in existing and future standards, aiding manufacturers and standard writers in clearly distinguishing medical robots from other medical electrical equipment.
- Methodologies: Exemplar methods for classifying and introducing DOA into existing and emerging technologies, including descriptive, binary, and weighted approaches.
- Real-world Examples: Informative annexes illustrate practical implementations, such as autonomous exoskeletons, surgical robots, and automated external defibrillators, highlighting the effects of DOA on risk management and usability.
Applications
IEC/TR 60601-4-1:2017 is applicable to a wide range of medical electrical equipment and systems that leverage autonomy, including but not limited to:
- Robotic Surgery Systems: Guidance on distinguishing between robotic-assisted and autonomous operation, and on ensuring consistent clinical performance and patient safety.
- Rehabilitation Devices: Frameworks for risk and usability assessment where wearables or exoskeletons incorporate varying degrees of autonomy to assist patients.
- Diagnostic and Therapeutic Equipment: Considerations for integrating autonomous functions such as closed-loop control or automatic image evaluation, under the umbrella of risk-managed, safe operation.
- Automated Medical Devices: Directions for manufacturers of devices such as automated external defibrillators (AEDs) to classify and manage risks linked to their autonomous functions.
- Healthcare IT Networks: Guidance on applying risk management to MES integrated within broader hospital networks and IT infrastructure, in line with IEC 80001-1.
This report is intended for medical device manufacturers, system integrators, and those developing or assessing standards for health technology, ensuring that new autonomous functions are introduced safely and effectively.
Related Standards
For comprehensive implementation, IEC/TR 60601-4-1:2017 should be considered alongside related international standards, including:
- IEC 60601-1:2005 & IEC 60601-1:2005/AMD1:2012: General requirements for basic safety and essential performance of medical electrical equipment.
- ISO 14971:2007: Application of risk management to medical devices.
- IEC 62304:2006 & AMD1:2015: Medical device software - Software life cycle processes.
- IEC 62366-1:2015: Application of usability engineering to medical devices.
