Abstract

BACKGROUND:

It is uncertain how changes in the U.S. Preventive Services Task Force breast cancer screening recommendations (from annual to biennial mammography screening in women aged 50-74 and grading the evidence as insufficient for screening in women aged 75 and older) have affected mammography use among Medicare beneficiaries.

MATERIALS AND METHODS:

Cohort study of 12 million Medicare fee-for-service women aged 65-74 and 75 and older to measure changes in 3-year screening use, 2007-2009 (before) and 2010-2012 (after), defined by two measures-proportion screened and frequency of screening by age, race/ethnicity, and hospital referral region.

RESULTS:

Fewer women were screened, but with similar frequency after 2009 for both age groups (after vs. before: age 65-74: 60.1% vs. 60.8% screened, 2.1 vs. 2.1 mammograms per screened woman; age 75 and older: 31.7% vs. 33.6% screened, 1.9 vs. 1.9 mammograms per screened woman; all p < 0.05). Black women were the only subgroup with an increase in screening use, and for both age groups (after vs. before: age 65-74: 55.4% vs. 54.0% screened and 2.0 vs. 1.9 mammograms per screened woman; age 75 and older: 28.5% vs. 27.9% screened and 1.8 vs. 1.8 mammograms per screened woman; all p < 0.05). Regional change patterns in screening were more similar between age groups (Pearson correlation r = 0.781 for proportion screened; r = 0.840 for frequency of screening) than between black versus nonblack women (Pearson correlation r = 0.221 for proportion screened; r = 0.212 for frequency of screening).

CONCLUSIONS:

Changes in screening mammography use for Medicare women are not fully aligned with the 2009 recommendations.
