ObjectivesHealthcare expenditures for dually eligible individuals covered by both Medicare and Medicaid constitute a disproportionate share of spending for the 2 programs. Fragmentation, inefficiency, and low-quality care have been long standing issues for this population. The objective of this study was to conduct an early evaluation of an innovative program that coordinates benefits for elderly dual eligibles.Study DesignLongitudinal cohort study.MethodsComparable sources of administrative claims from 2007 to 2009 were used to examine differences in 30-day rehospitalization between dual eligibles in Massachusetts participating in Senior Care Options (SCO), an integrated managed care program, and dual eligibles in Medicare fee-for-service. Multivariable logistic regression models with county and time fixed effects were used for estimation.ResultsWe found no statistically significant effect of SCO on rehospitalization, an area where coordinated care would be expected to make a substantial difference.ConclusionsOur results suggest that coordinating the financing and delivery of services through an integrated managed program may not sufficiently address the problems of inefficiency and fragmentation in care for hospitalized dual eligible enrollees.
