ANSI AAMI IEC 62366-1-2015 (2021) PDF

Full title and description

ANSI/AAMI/IEC 62366-1:2015 (Consolidated Text) with Amendment 1 (2020) — "Medical devices — Part 1: Application of usability engineering to medical devices". This consolidated American National Standard publishes the IEC international standard text (IEC 62366-1:2015) together with Amendment 1:2020 and the ANSI/AAMI adoption/reaffirmation, providing requirements and process guidance for applying usability (human factors) engineering to medical devices with a focus on safety-related user-interface aspects.

Abstract

This standard specifies a usability-engineering process that manufacturers can use to analyze, specify, develop and evaluate the usability of medical devices as it relates to safety. It is intended to identify use-related hazards and evaluate mitigation of risks from use errors (normal use) and to strengthen the linkage between usability engineering and risk management practices such as those in ISO 14971. The consolidated text includes Amendment 1 (2020) which corrects inaccuracies without changing the fundamental process.

Scope

Specifies a usability engineering process that manufacturers shall use to identify safety-related usability issues in medical device user interfaces, to assess associated risks, and to design and verify mitigations. The standard focuses on usability as it relates to safety (use errors and normal use) and integrates usability activities with the risk-management lifecycle; it does not provide an exhaustive tutorial on all human factors methods (guidance and further examples are referenced in related technical reports and Part 2 guidance). Amendment 1 clarifies and corrects aspects of the original 2015 text without changing the core process.

Key topics and requirements

• Establish a usability-engineering file and define usability engineering plan and activities.
• Identify user groups, use environments, and use scenarios relevant to device safety.
• Perform use-related hazard analyses to identify potential use errors and their causes and effects.
• Link usability findings to risk-management activities (e.g., ISO 14971) and incorporate mitigations into requirements and design.
• Iterative formative evaluation and verification/validation of user-interface design, including summative (validation) testing where appropriate for safety-related tasks.
• Document usability activities, rationale for risk control measures, and evidence in the usability-engineering file.

Typical use and users

Used by medical device manufacturers, human factors/usability engineers, design and development teams, regulatory affairs professionals, and quality/risk managers to plan and demonstrate application of usability engineering for device safety. Reviewers at regulatory agencies and notified bodies also use the standard to evaluate human factors input to submissions. The consolidated ANSI/AAMI adoption is commonly referenced in premarket submissions and conformity assessments.

Related standards

Commonly used with ISO 14971 (risk management for medical devices), IEC 62366 (original and Part 2 guidance materials), AAMI HE75 (human factors guidance), and other usability and safety guidance documents and technical reports that expand methods and examples for human-factors engineering in medical devices.

FAQ

Q: What is this standard?

A: IEC 62366-1:2015 (consolidated with Amendment 1:2020 and adopted as ANSI/AAMI/IEC 62366-1) is an international consensus standard that defines a usability-engineering process for medical devices with emphasis on safety and the prevention of use errors.

Q: What does it cover?

A: It covers a process for identifying user groups and use scenarios, analyzing use-related hazards, integrating findings with device risk management, iteratively designing and evaluating the user interface, and documenting the usability-engineering file and verification/validation evidence. The consolidated text includes clarifications from Amendment 1 (2020).

Q: Who typically uses it?

A: Device manufacturers, usability and human factors engineers, design teams, regulatory and quality professionals, and conformity assessment bodies—especially those preparing regulatory submissions or demonstrating that user-interface related risks have been addressed.

Q: Is it current or superseded?

A: The consolidated IEC 62366-1:2015+AMD1:2020 text is the current Part 1 edition and has been made available in an ANSI/AAMI consolidated national adoption (actions spanning 2020–2021). Users should check publisher listings or national bodies for any later amendments or revisions beyond Amendment 1.

Q: Is it part of a series?

A: Yes. Part 1 defines the requirements (this document). Part 2 (TIR/guidance) provides tutorial guidance and expanded descriptions of methods to assist manufacturers in applying the Part 1 requirements. The consolidated Part 1 text replaces earlier 2007 editions and amendments.

Q: What are the key keywords?

A: Usability engineering, human factors, medical device safety, use error, risk management, usability-engineering file, validation testing, user interface.
