Does the racial/ethnic composition of Medicare Advantage plans reflect their areas of operation?

ABSTRACT:

Objective

To assess the extent to which the racial/ethnic composition of Medicare Advantage (MA) plans reflects the composition of their areas of operation, given the potential incentives created by the Centers for Medicare & Medicaid Services' Quality Bonus Payments for such plans to avoid enrolling racial/ethnic minority beneficiaries.

Data sources/study setting

2009 Medicare Consumer Assessment of Healthcare Providers and Systems (MCAHPS) survey and administrative data from the Medicare Enrollment Database.

Data collection/extraction methods

We defined each plan's area of operation as all counties in which it had MA enrollees, and we created a matrix of race/ethnicity by plan by county of residence to assess the racial/ethnic distribution of each plan's enrollees in comparison with the racial/ethnic composition of MA beneficiaries in its operational area.

Principal findings

There is little evidence that health plans are selectively underenrolling blacks, Latinos, or Asians to a substantial degree. A small but potentially important subset of plans disproportionately serves minority beneficiaries.

Conclusions

These findings provide a baseline profile that will enable crucial ongoing monitoring to assess how the implementation of Quality Bonus Payments may affect MA plan coverage of minority populations.

Project description:BackgroundDifferences 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.MethodsAmong 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.ResultsBlack 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).ConclusionsDisparities 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:ImportanceMedicare Advantage (MA) plans, which disproportionately enroll racial/ethnic minorities and persons with socioeconomic disadvantage, receive bonus payments on the basis of overall performance on a 5-star rating scale. The association between plans' overall quality and disparities in quality is not well understood.ObjectiveTo examine the association between MA star ratings and disparities in care for racial/ethnic minorities and enrollees with lower income and educational attainment.Design setting and participantsThis cross-sectional study included 1 578 564 MA enrollees from 454 contracts across the 2015 and 2016 calendar years. Data analyses were conducted between June 2019 and June 2020.ExposuresSelf-reported race and ethnicity and low socioeconomic status (SES) (defined by low income or less than a high school education) vs high SES (neither low income nor low educational attainment).Main outcomes and measuresPerformance on 22 measures of quality and satisfaction determined at the individual enrollee level, aggregated into simulated star ratings (scale, 2-5) stratified by SES and race/ethnicity.ResultsA total of 1 578 564 enrollees were included in this analysis (55.8% female; mean [SD] age, 71.4 [11.3] years; 65.8% White; 12.3% Black; 14.6% Hispanic). Enrollees with low SES had simulated stratified star ratings 0.5 stars lower (95% CI, 0.4-0.6 stars) than individuals with high SES in the same contract. Black and Hispanic enrollees had simulated star ratings that were 0.3 stars (95% CI, 0.2-0.4 stars) and 0.1 stars (95% CI, -0.04 to 0.2 stars) lower than White enrollees within the same contracts. Black enrollees had a 0.4-star lower rating (95% CI, 0.1-0.7 stars) in 4.5- to 5-star contracts and a no statistical difference in 2.0- to 2.5-star-rated contracts (difference, 0.3 stars; 95% CI, -0.02 to 0.7 stars). Hispanic enrollees had a 0.6-star lower simulated rating (95% CI, 0.2-1.0 stars) in 4.5- to 5-star contracts and no statistical difference in 2- to 2.5-star contracts (difference, -0.01 stars; 95% CI, -0.5 to 0.4 stars). There was low correlation between simulated ratings for enrollees of low SES and high SES (difference, 0.2 stars; 95% CI, 0.03-0.4 stars) and between simulated ratings for White and Black enrollees (difference, 0.4 stars; 95% CI, 0.3-0.5 stars) and White and Hispanic enrollees (difference, 0.3 stars; 95% CI, 0.2-0.4 stars). As the proportion of Black and Hispanic enrollees increased in a contract, racial/ethnic disparities in ratings decreased.Conclusions and relevanceIn this cross-sectional study, simulated MA star ratings were only weakly correlated with those for enrollees of low SES in the same contract, and contracts with higher star ratings had larger disparities in quality. Measures of equity in MA plans' quality of care may be needed.
