Estimated health outcomes of breast cancer screening in the national breast and cervical cancer early detection program by race/ethnicity.

Purpose: To estimate the number of screenings received, life-years (LYs) saved, and number of screenings per LY saved per woman who participated in the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) (Program) compared with those who did not participate (no Program).

Methods: We developed a time-to-event simulation model to compare the outcomes of women participating in the Program vs. no Program, categorized by race/ethnicity. Model input parameters included data from the Program's minimum data elements, United States Cancer Statistics, National Health Interview Survey, and published literature. The Program's impact was calculated as the difference in LYs between the Program and no Program using data from 2010 to 2019.

Results: Among 1 million women of all races/ethnicities who participated in the NBCCEDP in the last 10 years, 457,152 (standard deviation [SD]: 848) received more screenings than those who did not participate. These participants saved an average of 0.027 LYs per woman screened. In addition, we estimated that about 17 screenings would be required to save an additional 1 LY per woman screened in the Program compared with no Program. Per woman screened by race/ethnicity, non-Hispanic Black women had the highest estimated 0.075 LYs saved, followed by Hispanic women with 0.025 LYs, non-Hispanic White with 0.014 LYs, and non-Hispanic American Indian/Alaska Native and Asian/Pacific Islander had the least health outcome with 0.011 LYs.

Conclusion: The reported findings underscore the importance of providing preventive health services to populations that might not otherwise have access to these services.
