Informatics Research Seminar: Clinical Data Quality for Secondary Use in the Learning Healthcare System
October 23 @ 4:00 pm - December 18 @ 5:00 pm EDT
Speaker: Franck Diaz, PhD
Presented from UNC-C
Broadcast Link: Seminar
At Duke, all seminars live or broadcast will be held in Hock Auditorium from 4-5 pm.
Electronic Health Record data is a fundamental to the development of learning healthcare systems, yet they present severe limitations for their reliable secondary analysis. Though clinical data often presents a high enough quality level for patient care and billing, their quality is often questioned for research applications. For example, clinical data are often found to contain inaccurate values, incomplete records, inaccessible information within clinical notes or just be recorded at an unusable level of granularity for specific analyses (e.g., yearly glucose level readings for research questions involving investigating daily changes). This seminar will describe some of these data quality limitations, introduce DataGauge: a practical process for systematically designing and implementing quality assessments of re-purposed clinical data, present data showing the impact of clinical workflows on the quality of clinical data sets and discuss the heterogeneity of such workflows that complicates the secondary use of clinical data.
Franck Diaz, PhD is an Assistant Professor of Health Analytics and Informatics at the Department of Public Health Science in the College of Health and Human Sciences at University of North Carolina at Charlotte (UNCC). He joined UNCC in August of 2019 after completing a K-12 PRIME fellowship program for the National Institute for General Medical Science at Wake Forest School of Medicine and being part of WakeHealth’s Clinical and Translational Science Institute. His research focuses on developing methods for the reliable reuse of clinical data and carrying out secondary analyses to uncover modes of failure in clinical data sets. Dr. Diaz holds a PhD in Health Informatics from the University of Texas Health Science Center at Houston’s School of Biomedical informatics. He also holds a specialized Biomedical Engineering degree from Polytech’Marseille in France.
