Medical Informatics: Opportunities for Improving Patient Care Ben Founding Director ( ), Human-Computer Interaction Lab Professor, Department of Computer Science Member, Institute for Advanced Computer Studies

IOM Report: Health IT and Patient Safety Problem - Poorly designed health IT can create new hazards in the already complex delivery of care. - Dosing errors, failure to detect life-threatening illnesses & delaying treatment due to poor HCI or loss of data have led to serious injury & death. Recommendations: - User-centered design & human factors applied to health IT Health-IT-and-Patient-Safety-Building-Safer-Systems-for-Better-Care.aspx

Strategic Health IT Advanced Research Projects (SHARP): Office of National Coordinator - Security of Health Information Technology - Patient-Centered Cognitive Support - Healthcare Application and Network Platform Architectures - Secondary Use of EHR Data Sharpc.org

Reducing Wrong Patient Errors: Animated Transitions & Photos

( Taieb-Maimon, Plaisant & Shneiderman, 2012) The combination of animation & photo resulted in a significant increase in error recognition rate relative to the control & animation groups  Dramatic implications for commercial systems Control Photo Combined 36% Animation 7% 43% 63%63% Reducing Wrong Patient Errors: Animated Transitions & Photos
