Among Medicare Advantage enrollees, the mortality of Hispanic enrollees in Puerto Rico was significantly higher than that of Hispanic enrollees in the US during 2010-2022.

After evaluating the association between the expanded Medicare Advantage supplemental benefits and plan composition, authors determined that adoption was not associated with large demographic shifts in enrollment.

Medicaid expansion was associated with substantial changes in Medicaid managed care plan composition, which may influence a plan’s performance on enrollee experience metrics.

The risk-adjusted 1-year mortality rate was not different between Medicare Advantage and traditional Medicare beneficiaries with kidney failure who initiated dialysis.

Medicare Advantage enrollees, particularly those with lower out-of-network benefits, may have restricted access to top-ranked hospitals for complex cancer care compared with traditional Medicare enrollees.

Integrated Medicare and Medicaid managed care may not sufficiently address the problems of inefficiency and fragmentation in care for hospitalized dual eligible enrollees.

This study examines patterns of high-risk prescribing in the elderly Medicare Advantage population and demonstrates that the practice varies widely by geography and drug class.
