AI-generated interface content in medical devices cannot be pre-translated, pre-tested, or submitted under EU MDR. The Adaptive UI Within Validated Language Boundaries principle defines the compliant design response before August 2027.
The WHO Surgical Safety Checklist achieved 98% compliance in Ontario and produced no mortality reduction. The problem was not the checklist. It was an interface that could not distinguish completion from genuine verification.
Five documented medical device failures reveal a single mechanism: error states treated as afterthoughts. The Error Afterthought Model explains why error messages can exist and still fail to protect patients.
Poor UX in healthcare causes patient harm, recalls, and burnout. Guide covers FDA/EU MDR human factors, alert fatigue, EHR issues, embedded GUI safety, and why early investment saves costs.
Medical devices often fail due to poor interface design, causing alarm fatigue and errors. Aviation’s proven human factors engineering offers a roadmap to safer, more effective medtech interfaces.
