Background – Evaluation of Use
• Nielsen’s Heuristics• 10 Usability principles
• Aerospace and Automotive Industry
• NASA
• Healthcare - Context of Use
• Pilot

Method
• Pilot Study
• Two House Officers + Two Wards (1 each)
• Ward A: 18 Long-Stay Elderly Patients with HIGH Dependency Scores
• Ward B: 10 Short-Stay Patients, Respite Care with Lower Dependency Scores than Ward A
• Questionnaire on use of EPR – over 5 days• Nielsens’s Heuristics & NASA-TLX
• Analysis

Nielsen’s Heuristics
• Feedback
• Speak User’s Language
• Clearly marked exits
• Consistency
• Prevent Errors
• Minimise User Memory Load
• Shortcuts
• Simple Dialogue
• Good Error Messages
• Help and Documentation

NASA-TLX
• Mental Demand
• Physical Demand
• Temporal Demand
• Effort
• Performance
• Frustration

Results - Overall NASA-TLX – HMW
Ward A: High Dependency Scenario Ward B: Lower Dependency Scenario

Results - Interpretation• Usability of EHR can vary over time
• As clinicians approach the end of their working day, performance dramatically declines
• As a result of Decreased Performance, more Effort needed
• Usability Evaluation methods in Healthcare should be more refined to give better information

Conclusion
• Nielsen’s Principles, while helpful, do not take into account • Context of System Use• Impact of User’s Mental Workload
• Human Factors should be incorporated into System Evaluation in Healthcare
• More Research is needed into task issues in healthcare and usability
