     Dr. Dixon is an Assistant Professor in the Department of Epidemiology at the Richard M. Fairbanks School of Public Health at Indiana University-Purdue University Indianapolis (IUPUI). His primary research focus is on the use of information and computing systems to improve public health practice and clinical outcomes. This research has included the development, testing, and implementation of measures that leverage secondary data captured from electronic health records.  Research platforms include Regenstrief Institute, Inc.'s Center for Health Services Research and Center for Biomedical Informatics - and the VA Health Services Research & Development  Center for Health Information and Communication where he is an Investigator in Residence. 


     Dr. Dixon is also involved with the Indiana Health Information Exchange (IHIE) and national HIE initiatives that aim to promote bi-directional exchange of health information to improve clinical and population health quality, effectiveness, and efficiency. His has contributed to the development and implementation of health information applications and systems, including tools supporting the standard clinical vocabulary LOINC®, technology supporting the automated electronic reporting of notifiable conditions, and tools for querying large clinical data repositories.

     Recent work includes leveraging clinical and administrative data in a health information exchange to improve public health reporting processes, disability determination, surveillance activities, continuity of care for Veterans, and community assessment. Dr. Dixon’s research also involves the evolution of information infrastructure as well as data quality to support continuous use of clinical data in support of efforts to improve health care quality, safety, and efficiency.

Study aimed to demonstrate technologies developed for the CDSC in two primary care practice locations in Indianapolis, Indiana utilizing the Regenstrief CareWeb EHR application. Study supports the CDSC's ongoing work to develop and evaluate open knowledge management platform for decision support tools. Role: Co-Investigator.


III. CDC 1P01HK000077  (2009-2014)

"Indiana Center of Excellence in Public Health Informatics" (PI: Shaun Grannis)

The project seeks to advance public health informatics through the development and maintenance of preeminent research, education, and practice. The project will support a number of multidisciplinary research and development activities in public health informatics over five years. Current projects include integration of geospatial data into the regional health information exchange (HIE) to enhance public health surveillance and reporting activities as well as enhance future clinical decision support services; improvement of identity matching algorithms and processes; and enhancement of electronic laboratory reporting using natural language processing techniques.
