Learn the power of GIS: explore the who, when and where behind health interventions, exposures, and outcomes

In our changing world, disease incidence and environmental risk are an ever-present topic of which we are all acutely aware. Understanding the association between environmental exposures and health outcomes, and mitigating them through sound interventions and planning requires an expanding, cross-disciplinarian work force, and powerful tools. One such tool is a Geographic Information System (GIS), which has become invaluable in the population health architecture.

GIS aids in the process of analyzing the distribution and determinants of disease and health exposures within a given population: while we commonly have detailed information on the who and when of a particular disease, GIS allows us to add critical information to the where. A GIS can compile geographic data from a multitude of sources and accommodate advanced visualization and analysis of these data. This process enables new value to be integrated into population health efforts, such as exploring the effect of environmental exposures (like land use, transportation networks, and air quality) on health outcomes, or identifying geographic barriers to health care access. GIS is critical to not only addressing geographic risks but also for guiding population health interventions. Moreover, supporting health needs and health equity within vulnerable communities can be effectively assessed through a geospatial approach.

If you have a passion for working in population health and making a difference to the health and well-being of your community, come learn how to leverage GIS in your work!

Using ArcGIS to map and analyze environmental and health information to support the local and national health needs of our society is an integral part of the applied skills training offered in the Population Health and Geographic Information Systems (PHDA 03) course. This course is accessible and valuable to first-time GIS users and seasoned public health practitioners alike. The next offering of PHDA03 is in Fall 2022.
