High-need phenotypes in Medicare beneficiaries: drivers of variation in utilization and outcomes.
The goal of this study was to identify distinct clinical phenotypes present within high-need Medicare beneficiaries and to examine differences in outcomes between phenotypes. Researchers identified five phenotypes and concluded that their findings represented a first step toward classifying the heterogeneity among high-need Medicare beneficiaries. They recommend further work to identify modifiable utilization patterns between phenotypes to improve the value of healthcare provided to these subpopulations.

Validity of race and ethnicity codes in Medicare administrative data compared with gold-standard self-reported race collected during routine home health care visits.
The authors compared the validity of two race/ethnicity variables found in Medicare administrative data against a gold-standard source also available in the Medicare data warehouse. They found that the race/ethnicity variables contained in Medicare administrative data for minority health disparities research can be improved through the use of self-reported race/ethnicity data. They conclude that future work to improve the accuracy of Medicare beneficiaries' race/ethnicity data should incorporate and augment the self-reported race/ethnicity data contained in assessment and survey data, available within the Medicare data warehouse.
