Using publicly reported data from Centers for Medicare &

Medicaid Services, researchers want to examine the relationship

between 30-day readmissions and mortality rates for patients
i,- i,- i,- i,- i,- i,- i,- i,-
with heart failure at five facilities. Before this can be done,
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
researchers need to estimate mortality rates and readmission
i,- i,- i,- i,- i,- i,- i,- i,-

cross-sectional data set of all urban hospitals from eight states is i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-
used in this study. The data were obtained from various

administrative databases: Medicare Hospital Cost Report i,- i,- i,- i,- i,- i,-
Information System, the American Hospital Association, and the
i,- i,- i,- i,- i,- i,- i,- i,-
