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.

The clinical course after long-term acute care hospital admission among older Medicare beneficiaries.
Investigators sought to examine the clinical course after long-term acute care (LTAC) admission. They found that hospitalized older adults transferred to LTAC hospitals had poor survival, spent most of their remaining life as an inpatient, and frequently underwent life-prolonging procedures. This prognostic understanding is essential to inform goals of care discussions and to prioritize healthcare needs for these adults. Given the exceedingly low rates of palliative care consultations, they recommend future research to examine unmet palliative care needs in this population.

Association between care management and outcomes among patients with complex needs in Medicare accountable care organizations.
This study compared the performance of accountable care organizations (ACOS) for prevention quality indicator admissions and 30-day all-cause readmissions including hospitalization and emergency department visits, evaluation and management visits in ambulatory settings, median annual spending, lower median health care contact days and lower continuity-of-care-index for Medicare patients. This cross-sectional study surveyed 244 Medicare Shared Savings Program ACOs in the 2017-2018 National Survey of ACOs (of 351 Medicare ACO respondents conducted from July 20, 2017, to February 15, 2018 that was linked to 2016 Medicare administrative claims data. The study population included Medicare beneficiaries 66 years or older who were defined as having complex needs with higher costs because of frailty or 2 or more chronic conditions. There was not found to be much difference in quality between the lowest and top tertiles for care management and coordination activities.

Medicare beneficiaries with advanced lung cancer experience diverse patterns of care from diagnosis to death.
Using Medicare claims data for patients diagnosed with extensive-stage small-cell lung cancer, the authors used latent class analysis to identify classes of people with different care patterns. The findings showed substantial heterogeneity in patterns of care for patients with advanced cancer, which should be accounted for in efforts to improve end-of-life care.

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.

Integrated Medicare and Medicaid managed care and rehospitalization of dual eligibles.
The objective of this study was to conduct an early evaluation of an innovative program that coordinates benefits for elderly dual eligibles. The authors found no statistically significant effect of senior care options on rehospitalization. They concluded 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.

Use of statins by Medicare beneficiaries post myocardial infarction: poor physician quality or patient-centered care?
This study assessed whether patterns of statin use by Medicare beneficiaries post-discharge may be due to a mix of high-quality and low-quality physicians. It found that the distribution of statin fill rates across physicians was normal, with no clear distinctions in physician quality. Physicians, especially cardiologists, with relatively younger and healthier patient populations had higher rates of statin use.
