ISO Definition of Usability 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: Ergonomics of Human System Interaction

SHARPC Definition of Usability Usability refers to how – useful, – usable, – satisfying a system is for the intended users to accomplish goals in the work domain by performing certain sequences of tasks Zhang J, Walji MF.

State of EHR Usability Senate panel to look into EHR usability 'After $28 billion in taxpayer dollars spent subsidizing electronic health records, ‎doctors don't like these electronic medical record systems.’ Unhappy with the state of electronic health records across the country two U.S. Senators have decided to take the matter into their own hands.

Understanding Users and their Work User-centered Design User Analysis User Personas Work Domain Analysis

Guidelines and Inspirational Prototypes General Usability Design Principles Safety Enhanced Design Briefs Inspired EHRs: Designing for Clinicians Twinlist: A Multi-Step Interface to Reconcile Medication Lists

Formative and Summative Evaluations Heuristic Evaluation – Extend to include accessibility heuristics User Testing – User Testing Scenarios – Representative Users

Governmental Responsibilities NIST Technical Guidance for EHR Usability Office of National Coordinator (ONC) – Safety Enhanced Design AHRQ

User/Buyer Responsibilities Active role in helping to design and evaluate Health IT systems Embed usability/accessibility into procurement process

Lessons Learned from EHR Usability Shared Responsibility – Health IT Vendors – Academics/Researchers – Users / Stakeholder groups – Government No quick fixes
