Abstract

BACKGROUND:

We examined mammography use before and after Medicare eliminated cost sharing for screening mammography in January 2011.

METHODS:

Using National Health Interview Survey data, we examined changes in mammography use between 2010 and 2013 among Medicare beneficiaries aged 65-74 years. Logistic regression and predictive margins were used to examine changes in use after adjusting for covariates.

RESULTS:

In 2013, 74.7% of women reported a mammogram within 2 years, a 3.5 percentage point increase (95% confidence interval, -0.3, 7.2) compared with 2010. Increases occurred among women aged 65-69 years, unmarried women, and women with usual sources of care and 2-5 physician visits in the prior year. After adjustment, mammography use increased in 2013 versus 2010 (74.8% vs. 71.3%, P=0.039). Interactions between year and income, insurance, race, or ethnicity were not significant.

CONCLUSIONS:

There was a modest increase in mammography use from 2010 to 2013 among Medicare beneficiaries aged 65-74 years, possibly consistent with an effect of eliminating Medicare cost sharing during this time. Findings suggest that eliminating cost sharing might increase use of recommended screening services.
