1. Compliance-Focused User Experience

These elements verify your interface meets key standards including IEC 62366 and AAMI's HE75 Human Factors Guidelines.

Have user testing phases been incorporated throughout development?

For example, prototype designs been evaluated with target users pre and post risk assessment?

Are essential functions visually emphasized?

Critical or permanent actions must be distinctly presented (e.g., "Administer" vs. "Stop").

Are safety measures reflected in visual and interactive elements?

For example, high-risk areas should have verification steps, input limitations, or guided processes.

Are potential mistakes addressed through interface design rather than documentation?

Should users navigate safely without consulting instruction manuals?

Does the system minimize reliance on extensive training?

Can healthcare staff operate the interface safely with basic guidance?

2. System Organization & Process Flow

Effective organization helps medical staff navigate efficiently, particularly during multitasking or time-sensitive situations.

Do processes align with established medical practices?

For example, vital signs entry should precede diagnostic options for nurses.

Is information arranged by importance or sequence?

Display critical elements (e.g., warnings, vital signs) clearly and continuously.

Are screens optimized for efficient reading?

Implement consistent spacing, alignment, and grid systems.

3. Notifications, Cautions & Error Management

Essential in medical settings. Ineffective alert design risks notification overload or missed alerts.

Are warning levels visually distinct?

Use consistent color, form, and positioning to indicate urgency.

Is alert frequency and attenuation appropriately balanced?

Avoid overwhelming users with excessive urgent notifications.

Are all notifications clear, simple, and solution-oriented?

For example, instead of showing 'Error', use 'Dose exceeds limit (20 mL). Please adjust.'"

Are interruptions limited to critical moments?

Reserve pop-up windows for essential alerts.

Is error recovery straightforward?

Provide clear reversal options after actions.

4. Interface Design & Inclusivity

Design should ensure readability, understanding, and universal access across medical settings.

Is the contrast obvious in all likely lighting conditions?

Button text should meet minimum WCAG AA standards.

Is all text legible from appropriate distances and with corrective eyewear?

Text should be sized and styled to support readability under real-world conditions—such as typical lighting and expected viewing distance—per IEC 62366 and FDA Human Factors Guidance.

Are clickable elements visually distinct beyond just color or tone?

Incorporate underlines, drop shadows, or hover effects to signal interactivity.

Does the interface avoid relying solely on color or tonal indicators?

Complement color and tonal signals with supporting icons or text labels.

5. Data Entry & Visualization

Input methods should be streamlined, validated, and clearly displayed, particularly for precision-critical data.

Are field labels distinct and immediately comprehensible?

Use standard terminology instead of unclear abbreviations or complex medical terms.

Do input fields provide useful preset values, parameters, or guidance?

For example, include units such as mmHg or contextual examples for entries like blood pressure.

Is information structured for quick recognition and verification?

Use clear tables or cards to group related data (e.g., vitals, meds, labs), supporting rapid scanning and reduced errors, as validated by user reaction time or task performance.

Can users verify critical inputs before final submission?

Include review steps for crucial data like medication dosages.

Is real-time input validation implemented?

Provide immediate alerts when values fall outside expected ranges.

6. Cognitive Load & Mental Models

Optimal interfaces reduce cognitive burden and protect against stress-induced errors.

Are all critical functions accessible within a maximum of three taps?

Users shouldn't navigate multiple menus for urgent actions like stopping infusions.

Are important functions indicated through multiple cues?

Combine visual elements like icons with text labels for clarity.

Are common workflows supported by preset values?

Include defaults to streamline routine procedures.

Is contextual information visible rather than memorized?

Display progress indicators and navigation paths clearly.

7. Environmental & Hardware Factors

Physical context and device compatibility significantly impact usability.

Does the interface work with prescribed protective equipment?

Ensure adequate spacing for gloved operation.

Has testing occurred on intended hardware?

Avoid desktop-centric design on mobile/embedded screens.

Are minimal-interaction workflows available as a user selection option?

Essential for surgical or mobile scenarios.

Does the interface adapt to screen rotation?

Support both orientations for tablet usage.

Is offline functionality handled appropriately?

Preserve data and core functions during connectivity issues.

8. System Feedback & Status Indicators

UIs must consistently communicate: "What's happening now and what's the next step?"

Are loading states clearly visible and precisely tracked?

Prevent user uncertainty about application responsiveness.

Do all actions receive unambiguous visual or audio confirmation?

Implement instant feedback for interactions, file transfers, and configuration changes.

Are extended operations shown with progress tracking?

For example, data synchronization, test execution, or system updates.

Are task status and history readily accessible?

For example, show metrics like 'Calibration completed: 2 hours ago' or step-completion indicators.

Does feedback avoid unnecessary interruptions?

Utilize subtle notifications instead of disruptive full-screen alerts.
