Use Error Prevention

Focuses on identifying and mitigating use errors that could lead to harm — not user convenience, but safety-critical interactions between users and the medical device user interface.

groups

User-Centered Process

Requires manufacturers to understand users, use environments, and user interface characteristics through structured analysis, including contextual inquiry and user profiles.

science

Summative Evaluation

Mandates summative (validation) usability testing with representative users performing critical tasks to provide objective evidence that the device can be used safely.

Who Needs to Comply?

groups

All medical device manufacturers, including software-as-a-medical-device (SaMD) developers. Required by the EU MDR, recognized by the FDA as a consensus standard, and referenced globally for regulatory submissions.

Key Requirements

Use Specification

Define the intended users, intended use environments, and user interface characteristics of the medical device. Establish a use specification document that drives all subsequent usability activities.

Hazard-Related Use Scenarios

Identify use scenarios where foreseeable use errors or correct use could lead to hazardous situations. Analyze the user interface to determine which tasks are safety-critical and require focused usability engineering.

Formative Evaluation

Conduct iterative formative evaluations during design and development to identify usability issues early. Methods include cognitive walkthroughs, heuristic evaluations, expert reviews, and user testing with prototypes.

Summative Evaluation

Perform summative (validation) usability testing with representative users in simulated or actual use environments. Demonstrate that users can perform critical tasks safely and that residual use-related risks are acceptable.

Usability Engineering File

Maintain a usability engineering file documenting the entire process — use specification, hazard analysis, formative and summative evaluations, and evidence that use-related risks have been adequately addressed.

Penalties & Enforcement

warning

No direct fines for non-compliance. However, inadequate usability engineering can lead to rejection of regulatory submissions (FDA 510(k)/PMA, EU MDR Technical Documentation), product recalls due to use errors, and liability exposure from patient harm caused by design-related use errors.
