Association of Medicare Advantage Star Ratings with racial, ethnic, and socioeconomic disparities in quality of care.
This cross-sectional study looked at racial/ethnic minority and socioeconomic disparities in ratings for Medicare Advantage (MA) plans, which disproportionately enroll these populations. A total of 1,578,564 enrollees were included in this analysis that used 22 measures of quality and satisfaction at the individual enrollee level, aggregated into simulated star ratings from 2-5 stratified by socioeconomic status (SES) and race/ethnicity. Low SES enrollees had simulated stratified star ratings 0.5 stars lower than individuals with high SES in the same contract. Black enrollees had simulated star ratings that were 0.3 stars lower and Hispanic enrollees had 0.1 lower simulated star ratings than White enrollees in the same contract. There was a larger difference in ratings with 4.5 to 5-star contracts with Black and Hispanic enrollees with Whites, and no statistical difference in 2.0 to 2.5 star-rated contracts. There was only low correlation between simulated ratings for enrollees of low SES and high SES.

Separable covariance models for health care quality measures across years and topics.
Public quality reports for Medicare Advantage health plans include 11 measures of patient experiences reported in the annual Consumer Assessment of Healthcare Providers and Systems surveys. To summarize associations among measures and years, the authors model the variance-covariance matrix governing the plan-level vectors of yearly quality measures as a Kronecker product of an across-measure matrix and an across-year matrix, or a sum of such Kronecker products.

Implications of variation in the relationships between beneficiary characteristics and Medicare Advantage CAHPS measures.
The researchers studied how differences in quality score adjustments across Medicare Advantage contracts change comparisons for individuals and contracts. They found that, for average consumers, standard adjustment is sufficient to represent variation in contract quality standardized to a common population. For people with characteristics far from average, personalized reporting using their characteristics and contract-specific coefficients can substantially change the expected quality measures across contracts.
