Development of a Versatile Geospatial Database within the CRN

Geographic information associated with health records and facilities has a broad range of applications, including calculation of geographic access to health services, examination of service areas for health care systems, and measurement of geographically-based exposures. This project, led by Dr. Andrea Cook (GHC) and Dr. Tracy Onega (Dartmouth Medical School), will expand existing geocoding infrastructure to create a versatile geospatial database that will include individual, demographic, and facility-level geographic variables. The geocoded facility and member data will be used to examine the influences of travel time to facility, facility availability, and socioeconomic indicators on receipt of surveillance mammography.
