The University of Maryland is one of the nine institutions participating in the National Center for Cognitive Informatics and Decision Making in Healthcare (NCCD) led by The University of Texas Health Science Center at Houston. NCCD is funded by the Office of the National Coordinator for Health IT under the Strategic Health IT Advanced Research Projects (SHARP) Program. This program seeks to support improvements in the quality, safety and efficiency of health care through advanced information technology. The NCCD award was one of four presented by the Office of the National Coordinator for Health Information Technology (ONC) through the American Recovery and Reinvestment Act of 2009 to address key barriers to health information technology. NCCD's research focus area is Patient-Centered Cognitive Suport.
The PROJET 4 of SharpC is Maryland studying and proposing novel interfaces for the following problems:
In addition we are also working on the following topics:
(A) Medication reconciliation
The Medication Reconciliation (Twinlist) project focuses on how visual layout and animation can help users see similarities in the lists and rapidly make decisions - with the Twinlist Interface.
(B) Results management
The Result Management project focuses on how to avoid missing results when ordering labs, tests or referals.
(C) Reducing Wrong Patient Selection Errors
The Wrong Patient Selection project focuses on interface improvements to reduce the problem. It demonstrates multiple interface suggestions.
(D) Visual comparison of treatment outcomes
We designed a new visualization to present summaries of outcome data to patients (or to the patient-provider team). We reviewed the literature and propose a framework for design (see paper below) and are now developping an interactive web-based prototype showing 4 alternative designs. The most promising prototype uses step by step animation to explain the new visualization. We are also preparing a user study to compare a text only design with the new designs.Paper

(E) Survey of visualization techniques for EHR dataOur literature review has now been published:

(F) Framework for Systematic Yet Flexible Systems Analysis (SYFSA)
[A project from our SharpC Project 4 partners at the University of Kentucky and the University of Texas] Contact: Todd R Johnson
This research on the Systematic Yet Flexible Systems Analysis (SYFSA) framework guides interface design even as it is continuously refined by our practical experience in applying it. We expect that SYFSA will enable the creation of Healthcare IT systems that encourage best practices while simultaneously accommodating the tremendous variety of real-world healthcare workflow. Systematic Yet Flexible Systems can provide visual and other cues to encourage evidence-based best practices along with visual feedback of progress while simultaneously supporting the need to deviate from these standards in some cases.Paper

(H) Understand Patterns in Patient Discharge Summaries
In this very exploratory project we applied network analysis and visualization tools to study a corpus of patient discharge summaries, exploring the relationships between patients and their associated symptoms, diseases, drugs, and procedures. Cody Dunne used the technology he had been developing in his PhD thesis (including motif simplification and group-in-a-box layouts) to reduce clutter as well as interactive text displays to show the origin of each relationship.Paper
