1 Medical Informatics: Opportunities for Improving Patient Care Ben Shneiderman ben@cs.umd.edu @benbendc Founding Director (1983-2000), Human-Computer Interaction Lab Professor, Department of Computer Science Member, Institute for Advanced Computer Studies

2 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 www.iom.edu/Reports/2011/ Health-IT-and-Patient-Safety-Building-Safer-Systems-for-Better-Care.aspx

3 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 www.cs.umd.edu/hcil/sharp

4 HCIL’s Research Initiatives Medical Lab Tests - Tracking Completion in Complex Workflows - Guidelines for Design of Tables & Actions - Retrospective Analysis Medication Reconciliation Patient Histories – Analysis & Search - Temporal Event Sequences - Point & Interval Events Wrong Patient Errors (BONUS)

5 Medical Lab Tests Tracking Sharpc.org www.cs.umd.edu/hcil/sharp

6 Medical Lab Tests Tracking & Retrospective Analysis www.cs.umd.edu/hcil/sharp

7 Medication Reconciliation: Current Form www.cs.umd.edu/hcil/sharp Univ of Maryland HCIL tasks - Missing Laboratory Reports - Medication Reconciliation - Alarms and Alerts Management www.youtube.com/watch?v=ZGf1EiuIIIM
