"3-Star EHR Visualization"

Robert S. Laramee, MSc., PhD, SFHEA
Professor of Visualization, The University of Nottingham

ABSTRACT: Since the inception of electronic health records (EHR) and population health records (PopHR), the volume of archived digital health records is growing rapidly. Large volumes of heterogeneous health records require advanced visualization and visual analytics systems to uncover valuable insight buried in complex databases. As a vibrant sub-field of information visualization and visual analytics, many interactive EHR and PopHR visualization (EHR Vis) systems have been proposed, developed, and evaluated by clinicians to support effective clinical analysis and decision making. We present the state-of-the-art (STAR) of EHR Vis literature and open access healthcare data sources and provide an up-to-date overview on this important topic. We identify trends and challenges in the field and introduce novel literature and data classifications. We then focus on two targeted applications: visualization of clinic letters and geospatial visualization of population health records. In both applications, we provide more detailed visualization solutions to exploring and visual analysis of EHRs and PopHRs. The presentation provides a valuable overview of EHR Vis revealing both mature areas and potential future multidisciplinary research directions.
