Development of a shareable analytic dataset for studies of racial disparities (IT Supplement)

The aim of this project was to develop a shareable analytic de-identified dataset to examine racial disparities in survival and cancer stage at diagnosis. We added data programs to the VDW to collect comorbidity data, which resulted in the establishment of an annotated centrally available SAS program designed to extract data for establishing the Charlson Comorbidity Index for newly diagnosed cancer patients. Also, we linked the cause of death codes to look-up tables to identify deaths due to specific cancers. With a project led by Dr. Chyke Doubeni, the project team is still attempting to include socioeconomic variables from the local sites through geocoded links to census data.
