Background

According to the American Diabetes Association, 11.3% of the US adult population had diabetes in 2010, with an estimated annual cost of $218 billion.  Through a grant from the Bristol-Myers Squibb Foundation, the Durham Diabetes Coalition is working to reduce the burden of diabetes in Durham County, NC.

Objective

Using spatial methods to characterize the geographic distribution of diabetes patients, community resources, and socioeconomic status across the county, we identified potential pilot neighborhoods.

Methods

We created a spatial data architecture that leveraged over 300,000 patient electronic health records (EHR) from Duke University Medical Center and Lincoln Community Health Center, census data, business location data, and information on community resources and partners. Spatial site selection methods considered the burden of type 2 diabetes, lack of healthy eating options, and the presence of a strong community base. Potential pilot areas were presented to a Community Advisory Board, which made the final selections. 

Results

Three pilot neighborhoods were chosen for initial intervention programs. The first pilot neighborhood is located in south-central Durham, based around the strong community presence of a well-respected religious institution. The second pilot neighborhood chosen is a historically minority and low socioeconomic neighborhood. The third pilot neighborhood is an area with a similarly low socioeconomic status and a strong community base. The strong community presence provides an important infrastructure on which to build successful interventions. 

Discussion

Spatial data and spatial analytical methods can identify patterns in health and existing community resources which can inform interventions aimed at improving health outcomes for high risk populations. By leveraging clinical and contextual data to identify pilot neighborhoods, we can implement interventions for diabetes care and education in areas that are receptive to those interventions and in the greatest need. This replicable strategy allows us to effectively focus limited resources.
