Protocol inconsistencies between the validation abstraction and the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) in the capture of “other” race, multiple races, and missing race or ethnicity data resulted in conservative other/multiracial concordance estimates.
The validation project abstracted data strictly from program medical records, of which 5.6% were missing race and ethnicity reports. NBCCEDP accessed administrative records to capture race or ethnicity data for the Minimum Data Elements (MDEs). In total, 288 abstracted records were missing race and ethnicity but were reported in the MDEs. Notably, among the undocumented abstracted records, all of the discordance corresponds to single non-Hispanic race or Hispanic ethnicity reports in the MDEs.
The undocumented outcome-specific concordance estimates are not meaningful because of the inconsistent protocols between the validation project and the MDEs with respect to missing race and ethnicity reports. In addition, these suppressed estimates are unstable with relative standard errors that exceed 30%.
