This Inclusion of Clinical Research Snapshot provides a summary of demographic representation for participants in Duke clinical research studies. The Inclusion of Clinical Research Snapshot presents information from studies as entered into the Duke clinical research management system (OnCore) with any accrual status as of March 25, 2021. We assessed the following demographic variables: age, gender, race, ethnicity, and rurality. Our primary objective is to determine the inclusion of traditionally underrepresented groups in research in Duke clinical trials.

Rurality was determined by using a file that maps zip codes to 2010 Rural-Urban Commuting Area Codes (RUCA codes). For a description, refer to https://www.ers.usda.gov/data-products/rural-urban-commuting-area-codes.aspx.2
Zip codes reported in OnCore were grouped using primary RUCA codes into rural and non-rural participant locations. More specifically, a primary RUCA code of 1, 2, or 3 was considered non-rural and codes 4 through 10 as rural.
2The USDA’s (U.S. Department of Agriculture) Economic Research Service publishes a dataset of RUCA codes at https://www.ers.usda.gov/data-products/rural-urban-commuting-area-codes.aspx.
