Usability and Human Factors

Usability and Human Factors

Technology should support clinicians — not compete with them.

Usability and human factors focus on designing systems that align with how people naturally think, move, and make decisions. In healthcare, poorly designed tools increase cognitive load, contribute to burnout, and introduce risk. Well-designed systems enhance clarity, safety, and efficiency.

Human-centered design recognizes that healthcare environments are fast-paced, high-stakes, and complex. Systems must reduce friction, not add to it.

Core Principles of Usability and Human Factors

1. Cognitive Load Management

Interfaces should minimize unnecessary clicks, duplicate documentation, and visual clutter. Reducing mental strain allows clinicians to focus on patient care.

2. Workflow Alignment

Technology must reflect real-world clinical workflows. Observing end users and incorporating feedback ensures systems support how work is actually performed.

3. Clear Information Hierarchy

Critical information should be easy to find and interpret. Logical layout, consistent formatting, and intuitive navigation improve speed and accuracy.

4. Error Prevention and Safety

Thoughtful design anticipates potential user mistakes and builds safeguards into the system. Smart alerts and validation rules should enhance safety without contributing to alert fatigue.

5. Continuous Feedback and Iteration

Usability is not a one-time effort. Ongoing evaluation, user feedback, and system refinement are essential for sustainable improvement.

Strong usability and human factors design bridge technology and human behavior. They recognize that the success of any system depends on the people who use it.

When systems are intuitive and aligned with human needs, performance improves, risk decreases, and care becomes more focused and effective.
