Characteristics, utilization, and concentration of outpatient care for dual-eligible Medicare beneficiaries.
The purpose of this study was to describe the distribution of outpatient care for dual-eligible Medicare beneficiaries ("duals") and characterize the intensity of outpatient care utilization of duals vs non-dual-eligible beneficiaries ("nonduals"). The researchers assessed the distribution of outpatient care across physician practices and compared the use of different outpatient services between duals and nonduals. The study found that nearly 80% of outpatient visits for duals were provided by 35% of practices. Compared with low-dual and no-dual practices, high-dual practices served more patients, with morhe comorbidities. Duals had 2 less outpatient visits per year compared with nonduals with substantially fewer subspecialty care visits despite having more comorbidities.

A national assessment of legacy versus new generation Medicaid data.
The purpose of the study was to review Medicaid legacy, Medicaid new generation, and Medicare claims across multiple states and compare performance on data analytic tasks. The researchers targeted the series of events that begins with a non-hospital-related medical emergency and ends with survival to discharge or death. Six data quality indicators were developed to evaluate the following: ambulance variables; code reporting for external cause of injury; linkage between claims; and death reporting on hospital discharge status codes. For death reporting on hospital discharge status codes the researchers estimated the severity of injuries and developed a model of its correlation with death in the Medicare population. The resulting model was utilized to compare reported versus expected deaths by level of injury severity in the Medicaid population. The study found that new generation Medicare claims had high performance across states and indicators, Medicaid legacy claims underperformed on multiple indicators in most states, and while new generation Medicaid claims outperformed Medicaid legacy claims on several indicators, conducting high-level analysis with that data will require substantial improvements.

Trends in end-of-life cancer care in the Medicare program.
The researchers sought to examine contemporary trends in end-of-life cancer care and geographic variation of end-of-life care aggressiveness among Medicare beneficiaries. They found that the proportion of beneficiaries receiving at least one potentially aggressive end-of-life intervention increased in repeated hospitalization, repeated ED visits, ICU admissions, and late hospice enrollment but declined in in-hospital death. End-of-life chemotherapy use did not change significantly over time. They concluded that despite growing focus on providing appropriate end-of-life care, there has not been an improvement in aggressive end-of-life cancer care in the Medicare program.
