Rural Population Management/Clinical Phenotyping with Geographic Methods

Applied geographic methods allow researchers the ability to explore health service utilization for specific patient populations to better address geographic access disparities.

Example Projects

NCCC Catchment Query Portal

Health care data have the potential to provide a much more detailed understanding of what cancer care services are being delivered where and to whom. Improving knowledge about the accessibility of cancer care services for populations that need to access them will enable health care delivery systems, facilities, and patients to better align resources with patients’ need and ensure that patients have access to specialized cancer care. We developed a geoanalytic system that enables the Norris Cotton Cancer Center (NCCC) to determine the extent of its “reach” into communities and to continually monitor our patient catchment areas, including satellites/affiliates, in relation to geographic extent, populations served, cancer characteristics, and access.
