Informatics Research Seminar: Iterative Methodology and Usability Improvement for Clinical Decision Support

January 14 @ 4:00 – 5:00 pm

Speaker: Fei Yu, PhD
Presented from UNC-CH

Broadcast Link: Seminar



MindsEye is a visual-based interactive clinical decision support (CDS) tool and is currently undergoing phased usability testing. Simultaneously, an iterative methodology for evaluating the usability of CDS user-interfaces (UI) is being developed and refined. Phase I of the project developed and evaluated a UI. Results revealed methodological challenges and the need to better align the UI with clinical workflows. The Phase II UI is improved based on the lessons learned from Phase I. This presentation will introduce the Phase II evaluation results and findings.


Fei Yu, PhD is currently working as a Research Associate at the Lab of Applied Informatics Research in the School of Information and Library Science at UNC-Chapel Hill. She is also an enrolled CHIP program student who started pursuing a certificate in Clinical Health Informatics and then continued to seek a Master degree in Biomedical and Health Informatics at UNC-Chapel Hill. Dr. Yu completed her doctoral study in 2006 at the Department of Library and Information Science at the University of Pittsburgh. Her dissertation was the evaluation of users’ emotional and material satisfaction — at both micro and macro levels — with an academic library system. After she graduated, Dr. Yu worked for a non-profit technology company in Pittsburgh for several years. One of her job responsibilities was conducting routine usability testing for the web OPAC, which was shared by 85 public libraries in Allegheny County. She developed an interest in healthcare and electronic health records in 2012 when her family moved to North Carolina and plans to continue study in this highly interdisciplinary field and to pursue research opportunities by collaborating with both academia and industry.
