Elimination of Cost Sharing for Screening Mammography in Medicare Advantage Plans.

ABSTRACT: The Affordable Care Act (ACA) required most insurers and the Medicare program to eliminate cost sharing for screening mammography.We conducted a difference-in-differences study of biennial screening mammography among 15,085 women 65 to 74 years of age in 24 Medicare Advantage plans that eliminated cost sharing to provide full coverage for screening mammography, as compared with 52,035 women in 48 matched control plans that had and maintained full coverage.In plans that eliminated cost sharing, adjusted rates of biennial screening mammography increased from 59.9% (95% confidence interval [CI], 54.9 to 65.0) in the 2-year period before cost-sharing elimination to 65.4% (95% CI, 61.8 to 69.0) in the 2-year period thereafter. In control plans, the rates of biennial mammography were 73.1% (95% CI, 69.2 to 77.0) and 72.8% (95% CI, 69.7 to 76.0) during the same periods, yielding a difference in differences of 5.7 percentage points (95% CI, 3.0 to 8.4). The difference in differences was 9.8 percentage points (95% CI, 4.5 to 15.2) among women living in the areas with the highest quartile of educational attainment versus 4.3 percentage points (95% CI, 0.2 to 8.4) among women in the lowest quartile. As indicated by the difference-in-differences estimates, after the elimination of cost sharing, the rate of biennial mammography increased by 6.5 percentage points (95% CI, 3.7 to 9.4) for white women and 8.4 percentage points (95% CI, 2.5 to 14.4) for black women but was almost unchanged for Hispanic women (0.4 percentage points; 95% CI, -7.3 to 8.1).The elimination of cost sharing for screening mammography under the ACA was associated with an increase in rates of use of this service among older women for whom screening is recommended. The effect was attenuated among women living in areas with lower educational attainment and was negligible among Hispanic women. (Funded by the National Institute on Aging.).

Project description:ImportanceSeveral policy proposals advocate introducing copayments for home health care in the Medicare program. To our knowledge, no prior studies have assessed this cost-containment strategy.ObjectiveTo determine the association of home health copayments with use of home health services.Design, setting, and participantsA difference-in-differences case-control study of 18 Medicare Advantage (MA) plans that introduced copayments for home health care between 2007 and 2011 and 18 concurrent control MA plans. The study included 135 302 enrollees in plans that introduced copayment and 155 892 enrollees in matched control plans.ExposuresIntroduction of copayments for home health care between 2007 and 2011.Main outcomes and measuresProportion of enrollees receiving home health care, annual numbers of home health episodes, and days receiving home health care.ResultsCopayments for home health visits ranged from $5 to $20 per visit, which were estimated to be associated with $165 (interquartile range [IQR], $45-$180) to $660 (IQR, $180-$720) in out-of-pocket spending for the average user of home health care. The increased copayment for home health care was not associated with the proportion of enrollees receiving home health care (adjusted difference-in-differences, -0.15 percentage points; 95% CI, -0.38 to 0.09), the number of home health episodes per user (adjusted difference-in-differences, 0.01; 95% CI, -0.01 to 0.03), and home health days per user (adjusted difference-in-differences, -0.19; 95% CI, -3.02 to 2.64). In both intervention and control plans and across all levels of copayments, we observed higher disenrollment rates among enrollees with greater baseline use of home health care.Conclusions and relevanceWe found no evidence that imposing copayments reduced the use of home health services among older adults. More intensive use of home health services was associated with increased rates of disenrollment in MA plans. The findings raise questions about the potential effectiveness of this cost-containment strategy.

Project description:Differences in the control of blood pressure, cholesterol, and glucose among the various racial and ethnic groups of Medicare enrollees may contribute to persistent disparities in health outcomes.Among elderly enrollees in Medicare Advantage health plans in 2011 who had hypertension (94,171 persons), cardiovascular disease (112,039), or diabetes (105,848), we compared the respective age-and-sex-adjusted proportions with blood pressure lower than 140/90 mm Hg, low-density lipoprotein cholesterol levels below 100 mg per deciliter (2.6 mmol per liter), and a glycated hemoglobin value of 9.0% or lower, according to race or ethnic group. Comparisons were made nationally and within regions and health plans, and changes since 2006 were assessed.Black enrollees in 2006 and 2011 were substantially less likely than white enrollees to have adequate control of blood pressure (adjusted absolute differences in proportions of enrollees in the 2 years, 7.9 percentage points and 10.3 percentage points, respectively), cholesterol (11.4 percentage points and 10.2 percentage points, respectively), and glycated hemoglobin (10.1 percentage points and 9.4 percentage points, respectively) (P<0.001 for all comparisons). Differing distributions of enrollees among health plans accounted for 39 to 59% of observed disparities in 2011. These differences persisted in 2011 in the Northeast, Midwest, and South (6.9 to 14.1 percentage points, P<0.001 for all comparisons) but were eliminated in the West for all three measures (<1.5 percentage points, P?0.15). Hispanic enrollees were less likely than whites in 2011 to have adequate control of blood pressure (adjusted difference, 1.6 percentage points), cholesterol (adjusted difference, 1.0 percentage points), and glycated hemoglobin (adjusted difference, 3.4 percentage points) (P?0.02 for all comparisons). Asians and Pacific Islanders were more likely than whites to have adequate control of blood pressure (difference, 4.4 percentage points; P<0.001) and cholesterol (5.5 percentage points, P<0.001) and had similar control of glycated hemoglobin (0.3 percentage points, P=0.63).Disparities in control of blood pressure, cholesterol, and glucose have not improved nationally for blacks in Medicare Advantage plans, but these disparities were eliminated in the West in 2011.

Project description:BackgroundSince 2005, the Centers for Medicare and Medicaid Services (CMS) has required all Medicare Advantage (MA) plans to report prescribing rates of high risk medications (HRM).ObjectiveTo determine predictors of receipt of HRMs, as defined by the National Committee for Quality Assurance's "Drugs to Avoid in the Elderly" quality indicator, in a national sample of MA enrollees.Design and participantsRetrospective analysis of Healthcare Effectiveness Data and Information Set (HEDIS) data for 6,204,824 enrollees, aged 65 years or older, enrolled in 415 MA plans in 2009. To identify predictors of HRM use, we fit generalized linear models and modeled outcomes on the risk-difference scale.Main outcome measuresReceipt or non-receipt of one or two HRMs.Key resultsApproximately 21 % of MA enrollees received at least one HRM and 4.8 % received at least two. In fully adjusted models, females had a 10.6 (95 % CI: 10.0-11.2) higher percentage point rate of receipt than males, and residence in any of the Southern United States divisions was associated with a greater than 10 percentage point higher rate, as compared with the reference New England division. Higher rates were also observed among enrollees with low personal income (6.5 percentage points, 95 % CI: 5.5-7.5), relative to those without low income and those residing in areas in the lowest quintile of socioeconomic status (2.7 points, 95 % CI: 1.9-3.4) relative to persons residing in the highest quintile. Enrollees ? 85 years old, black enrollees, and other minority groups were less likely to receive these medications. Over 38 % of MA enrollees residing in the hospital referral region of Albany, Georgia received at least one HRM, a rate four times higher than the referral region with the lowest rate (Mason City, Iowa).ConclusionsUse of HRMs among MA enrollees varies widely by geographic region. Persons living in the Southern region of the U.S., whites, women, and persons of low personal income and socioeconomic status are more likely to receive HRMs.
