CONTEXT: THE SHARP-C PROJECT
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 Support.For more information see:
1) the NCCD website at the University of Texas in Houston (the main PI) OR
2) the Maryland webpage which provides a summary of all the SharpC projects HCIL participated in.
Medication reconciliation is an important and complex task for which careful user interface design has the potential to help reduce errors and improve quality of care. In this project we focused on the inpatient situation: a clinician is in the process of discharging a patient from the hospital and needs to compare the list of home medications with the medications dispensed at the hospital and decide what the patient should take when he/she returns home.
The main output of this project is a novel interface called Twinlist, which illustrates the use of spatial layout and multi-step animation, to help medical providers see what is different and what is similar between the lists (e.g. intake and hospital lists), and rapidly select the drugs they want to include in the reconciled list.
Other prototypes were designed to present alternative user interfaces: variations on the Twinlist interface, and an interface called Medrec developed by our collaborators at Houston.
Those interfaces were built on the substratum of a novel medication reconciliation algorithm that computes the similarity between drugs. That similarity information can then be presented to the clinician by the user interface, and remove the tediousness of a fully manual reconciliation without diminishing the decision making power of the clinician.
The basic design of Twinlist can be adapted to other reconciliation tasks such as problem reconciliation or allergy reconciliation.Papers

Open Source Software
- The SIMILARITY ALGORITHM computing similarity between drugs is available for download at https://github.com/jherskovic/MedRec PLEASE Contact: Jorge R. Herskovic for possible updates.
Try the direct link to a LIVE DEMO of TWINLIST with a simple case (use Chrome or Safari, with a window that is not too large - IE will not work properly)
OR: you can find the Twinlist interface source CODE and more LIVE DEMOScan be HERE (as a "playground" to tryout different designs and test cases) PLEASE PLEASE PLEASE Let us know if you use it :) - Contact Catherine Plaisant, and give credit to the University of Maryland.
- Jorge Herskovic's alternative MEDREC INTERFACE source code is also available. See https://github.com/jherskovic/MedRecUI. Contact: Jorge R. Herskovic.
- Jorge Herskovic also led the PanSHARP project and developed a SMART Platform version of Twinlist for this integration demonstration project.
