Public Health Informatics

Public Health Informatics

The Regenstrief Institute and the IU Richard M. Fairbanks School of Public Health at IUPUI have established a collaborative program in public health informatics (PHI) to facilitate research, teaching and service. The program seeks to apply informatics methods to address population health challenges, including but not limited to the surveillance of infectious and chronic disease, decision support for public health leaders, and translation of evidence-based interventions into public health practice. 

Other Research Opportunities

Undergraduates as well as MPH and other graduate students also have opportunities to pursue applied research in public health informatics at the Fairbanks School of Public Health and Regenstrief Institute. Capstone, thesis, internship and other practicum projects can be completed under the supervision of faculty and staff mentors who help students learn both scientific and professional skills. These skills enhance resumes and prepare students to enter the professional informatics workforce in public health and healthcare organizations.

What We Do

Our faculty and students conduct exciting, cutting-edge research in many areas of public health informatics, including:

  • health information exchange for population health
  • health services research in VA and safety net facilities
  • enhancing public health surveillance systems and methods
  • community health assessment leveraging EHR systems
  • integration of data as well as large-scale data management

“The unique partnership between IUPUI and the Regenstrief Institute allows me to conduct research with data from one of the nation's largest health information exchanges.  With this data, I can conduct research that I would not be able to in another place in the nation. Here I can utilize billions of health data elements to create and assess methods of identifying and tracking diseases which affect the state of Indiana.”

Evaluating the Impact of Health Information Exchange on Population Health Outcomes

Health Information Exchange (HIE) consists of methods and tools that support population health in public health and healthcare systems. Regenstrief faculty advance methods to evaluate HIE implementation and outcomes. In a review of HIE evaluations, HIE was found to have generally beneficial effects, including positive outcomes like reducing repeat medical tests and health care costs.

Examples of HIE Evaluation Findings
Reduction in repetition of medical procedures and repeat imaging
Identification of medication discrepancies
Savings related to reductions in ED use and readmission
Savings due to reductions in repeat imaging
