1 Component 7: Working with HIT Systems Unit 5: Fundamentals of Usability in HIT Systems – What Does It Matter? This material was developed by Johns Hopkins University, funded by the Department of Health and Human Services, Office of the National Coordinator for Health Information Technology under Award Number IU24OC000013.

2 Unit 5: Objectives Define usability and its relationship to HIT systems. Explain the impact of HIT usability on user satisfaction, adoption, and workarounds including error rates and unintended consequences. Provide alternatives to HIT usability bottlenecks. Component 7/Unit 52 Health IT Workforce Curriculum Version 2.0/Spring 2011

3 Usability Defined “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.” ISO 9241-11 (Ergonomic Requirements for Office Work with Visual Display Terminals (VDTs) – Part 11 Guidance on Usability. ISO/IEC 9241) Usability is the study of the ease with which people can employ a particular tool or other human-made object in order to achieve a particular goal. Component 7/Unit 53 Health IT Workforce Curriculum Version 2.0/Spring 2011

4 Jakob Nielsen Usability – a quality attribute that assesses how easy user interfaces are to use 5 6 Components: –Learnability –Efficiency –Memorability –Errors –Satisfaction –Utility http://www.usability.gov/basics/ Component 7/Unit 54 Health IT Workforce Curriculum Version 2.0/Spring 2011
