      Purpose/Objectives: To support Fraser Health’s Integrated Plan of Care initiative at Abbottsford Regional Hospital, an electronic documentation tool has been selected. This tool enhances inter-professional care planning and collaboration. Ensuring the usability and safety of the tool has become critical.

      Methodology/Approach: A framework for applying usability engineering to ensuring system usability and safety of health information technology developed by Broycki et al. (Broycki et al., 2013) has been employed in designing and building the tool. A series of multilayered user tests of the electronic documentation tool have been performed beginning with basic usability inspection and cognitive walk-through, followed by usability testing and limited clinical simulations. A framework for applying usability engineering to ensuring system usability and safety of health information technology developed by Broycki et al.

      Finding/Results: Usability Inspection: • Both positive and negative features of the tool were identified • Informed design and build / customization Usability Checklist: • Completed by the development team to check the compliance of the usability heuristics of the prototypes they built • Served as a guideline to form the discussion around design between the development team and stakeholders Usability Test: • 14 build packages, all of which were tested at least once (29 tests in total) • Created 5 formal Usability Test reports and 24 brief summaries Clinical Simulation Test: • 24 frontline clinical participants (Nursing: 17, Allied Health: 7) • Covered 95% of the identified workflow in Medicine, Surgery and Critical Care areas • 19 designed test cases Results informed training, highlighted anticipated questions, and mitigated issues that might occur during real patient encounters Usability Inspection: • Both positive and negative features of the tool were identified • Informed design and build / customization Usability Checklist: • Completed by the development team to check the compliance of the usability heuristics of the prototypes they built • Served as a guideline to form the discussion around design between the development team and stakeholders Usability Test: • 14 build packages, all of which were tested at least once (29 tests in total) • Created 5 formal Usability Test reports and 24 brief summaries Clinical Simulation Test: • 24 frontline clinical participants (Nursing: 17, Allied Health: 7) • Covered 95% of the identified workflow in Medicine, Surgery and Critical Care areas • 19 designed test cases • Results informed training, highlighted anticipated questions, and mitigated issues that might occur during real patient encounters

      Conclusion/Implications/Recommendations: Synergistic use of usability checklist, heuristic review, “think-aloud” protocol and “near-live” clinical simulations provide a robust assessment of how the clinical documentation tool would interact in live clinical environments and allows for early redesign to increase clinician utilization. Integration of the usability checklist and the framework in the design, development and test phases buttress efforts to achieve safe technology in healthcare.

      140 Character Summary: Integrating usability framework and user-centered design method in Health IT projects advances efforts to achieve safe technology in healthcare.
