BACKGROUND The objectives of this study were to evaluate the quality of national data generated by the National Breast and Cervical Cancer Early Detection Program (NBCCEDP); to assess variables collected through the program that are appropriate to use for program management, evaluation, and data analysis; and to identify potential data‐quality issues. METHODS Information was abstracted randomly from 5603 medical records selected from 6 NBCCEDP‐funded state programs, and 76 categorical variables and 11 text‐based breast and cervical cancer screening and diagnostic variables were collected. Concordance was estimated between abstracted data and the data collected by the NBCCEDP. Overall and outcome‐specific concordance was calculated for each of the key variables. Four screening performance measures also were estimated by comparing the program data with the abstracted data. RESULTS Basic measures of program outcomes, such as the percentage of women with cancer or with abnormal screening tests, had a high concordance rate. Variables with poor or inconsistent concordance included reported breast symptoms, receipt of fine‐needle aspiration, and receipt of colposcopy with biopsy. CONCLUSIONS The overall conclusion from this comprehensive validation project of the NBCCEDP is that, with few exceptions, the data collected from individual program sites and reported to the CDC are valid and consistent with sociodemographic and clinical data within medical records.
