During this webinar, Managing Director Robert Schumacher discussed the recently released Electronic Health Record (EHR) Usability Protocol from the National Institute of Standards and Technology. User Centric has been heavily involved in ensuring EHRs are evaluated for usability.

This webinar provides insights and tactics to help you:
• Position usability next to other methods of evaluating electronic health records
• Show the application of some key human performance principles to EHR design
• Discuss the emerging methods of expert review and validation testing for evaluating and measuring user performance of EHRs

    • 1. Presenter:Robert Schumacher, PhD.Managing DirectorUser Centric, Inc Moderator: Pamela Stoffregen-Gay Sr. Marketing Manager User Centric, Inc #uxlunch
    • 2. UATAesthetic Functional Attitude & Opinion (These are not behavior)
    • 3. SAY ≠DO
    • 4. A couple of caveats… 4
    • 5. User Experience Encompasses Usability User Experience (UX) Usability 5
    • 6. Utility (Usefulness) Useful Does Not Mean Usable Usable Does Not Mean Useful Usability
    • 7. yü-zə-ˈbí lə-tē -from O.Fr. usable (1311), from user (see use). Not a common word before c.1840.The extent to which a product can be usedby specified users to achieve specifiedgoals with effectiveness, efficiency, andsatisfaction in a specified context of use ISO definition
    • 8. Psychology Cognitive Human Factors Engineering::Physics as Human Factors::Psychology Usability

Methods of measuring Principles of behavior thatbehavior inform design Reaction time  Performance  Memory Errors  Cognitive workload  Motor capabilities Eye tracking  Attention  Signal detection …  Psycholinguistics  Choice theory  …There is a rich history of Knowledge of humanconstructing studies to capabilities embodied in userunderstand and explain interface design can optimizehuman performance user performance

    • 11. A Negative A Positive statement,statement, with No with Yes (affirmative)(negative) response response Yes or No? The circle isis above the star The circle not above the star
    • 12. Negative statement, Positive statement, with No (negative) with Yes (affirmative) response response The circle is not The circle is above the star above the star• Positive statements evoke faster responses than negative statements• Yes responses are much faster than No responses (~ 500 msec)
    • 13. Positive Logically Negative Equivalent Affirmative Negative Response ResponseDifferent phrasings are used when you want different responses- Large variability in cognitive processing times- Significant impact on error
    • 14. Statement Type Use When True/Affirmative Fast, easy, low-cost-to-user outcome, confirmation only False/Affirmative Need user to think about the response, high cost to use True/Negative Should almost never use False/Negative Never use, unless trying to deceive user e.g., Opt out response

    • 16. Ready…
    • 17. When was the patient’shighest platelet count?
    • 18. Human performance depends on how well tools are designed Change interface = Change performance
    • 19. How do we measure that change?How do we understand users, tasks and environments?

    • 26.  Apply existing established human factors methods in the technical evaluation (i.e., measurement) of EHR Usability Focus on critical aspects of usability (related to patient safety) Provide detailed systematic steps for conducting measurement usability validation studies Provide a framework for reporting usability findings Not a policy document or framework
    • 27. Who are the users?What is the user’s environment?What are their tasks?How well does the application do thetasks in the environment for the users?What mistakes might users make?How has the application been designed to mitigate mistakes andoptimize usability?
    • 28. An evaluation of the critical components of the user interfaceby executing various use case scenarios.Clinical subject matter experts together with usability / humanfactors experts conduct a structured evaluation of the userinterface.
    • 29.  image • In order to assure independence in the review process, each expert reviews the user interface on his/her own and produces a set of ratings and findings. • Once all experts have completed the evaluations, a lead expert consolidates all the findings into a single report.
