Use of EHR-based cohorts for research requires informed extraction, harmonization, and operationalization of EHR data. Dr. Hebert-DeRouen will describe the development of an EHR-based cohort with data from three healthcare systems linked to population-based cancer registry data to examine clinical and neighborhood factors that contribute to racial and ethnic disparities in liver cancer. She will detail operationalization of detailed race/ethnicity (17 categories) and liver cancer risk factors from EHR data; illustrate the utility of linking EHR data to cancer registry data; and present results on racial/ethnic disparities in liver cancer as well as the relative prevalence and contribution of risk factors to liver cancer diagnosis across racial/ethnic groups.
