Although spending rates on health care and social services vary substantially across the states, little is known about possible association between variation in state-level outcomes allocation of state services. To estimate that association, we used repeated measures multivariable modeling for period 2000-09, with region time fixed effects adjusted total demographic economic characteristics one- two-year lags. We found states a higher ratio to (calculated as sum service public divided by...

The objective of risk adjustment is not to predict spending accurately but support the social goals a payment system, which include equity. Setting population-based payments at accurate predictions risks entrenching levels that are insufficient mitigate impact determinants on health care use and effectiveness. Instead, advance equity, must be set above current for historically disadvantaged groups. In analyses intended guide such reallocations, we found community-dwelling Medicare population...
