Improvement in activities of daily living during a nursing home stay and one-year mortality among older adults with sepsis.
This study looked at the association between recovery of activities of daily living (ADLs) during a skilled nursing facility (SNF) stay and 1-year mortality after SNF discharge among Medicare beneficiaries treated in intensive care for sepsis. This retrospective cohort study identified 59,383 Medicare beneficiaries who were admitted to an SNF within 3 days of discharge from hospitalization that included time in an ICU for sepsis from all of 2013 to October 2015. About 58% of SNF residents showed improvement in ADL function. The higher the improvement in ADL score the less the mortality risk compared to residents who did not improve.

Outcomes of Medicaid home- and community-based long-term services relative to nursing home care among dual eligibles.
This study measured the outcomes of dual-eligible recipients of Medicaid home- and community-based long-term services (HCBS) compared to nursing home residents. The authors used the 2005 and 2012 Medicaid Analytic eXtract (MAX) database, a national compilation of Medicaid claims which merges Medicare claims to identify hospital admissions. A cohort of 1,312,498 older adults dually enrolled in Medicaid and Medicare and using long-term care was tracked. HCBS users were found to have 10 percent points higher annual rates of hospitalization than their nursing home counterparts when selection bias is addressed. The differences persisted across races, dementia status, and intensity of HCBS spending.

Inter-hospital transfer and patient outcomes: a retrospective cohort study.
Inter-hospital transfer (IHT, the transfer of patients between hospitals) occurs regularly and exposes patients to risks of discontinuity of care, though outcomes of transferred patients remains largely understudied. The purpose of this retrospective cohort study was to evaluate the association between IHT and healthcare utilisation and clinical outcomes. The investigators concluded that IHT was associated with higher costs, longer LOS and lower odds of discharge home, but was differentially associated with odds of early death and 30 -day mortality depending on patients' disease category.

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.

Long-term outcomes among Medicare patients readmitted in the first year of hemodialysis: a retrospective cohort study.
This retrospective cohort study examined long-term outcomes among Medicare patients with end-stage renal disease (ESRD) during the first year of hemodialysis. The goal was to determine hospital readmission patterns in the first year of dialysis and outcomes in the second year. Data from the United States Renal Data System (USRDS) was used and readmission patterns were summarized as either no readmission within 30 days, at least one admission, but not within 30 days, and admission with at least one readmission within 30 days. About half of all patients did not get readmitted (51%), but 18.5% were readmitted within 30 days, and 30.5% were admitted but not within 30 days. Those who were readmitted within 30 days had the highest long-term risk of mortality, hospitalization and lower likelihood of kidney transplantation compared to patients who were not admitted or readmitted.

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.

Clostridium difficile infection increases acute and chronic morbidity and mortality.
The goal of this study was to quantify short- and long-term outcomes of Clostridium difficile infection in the elderly, using 2011 Medicare claims data. The claims records of 174,903 patients coded for Clostridium difficile infection were compared with those of 1,318,538 control patients. The authors concluded that Clostridium difficile infection was associated with increased risk of short- and long-term adverse outcomes, including transfer to short- and long-term care facilities, hospitalization, and all-cause mortality.

Advanced practice provider versus physician-only outpatient follow-up after acute myocardial infarction.
This study examines the prevalence of using advanced practice providers (APPs) for care following myocardial infarction as opposed to physicians due to physician shortages and reimbursement changes. Outpatient cardiology or primary care visits within 90 days of MI among 29,477 Medicare-insured patients aged 65 or older from 364 hospitals were examined from data in the Acute Coronary Treatment Intervention Outcomes Network Registry. Medicare adherence, all-cause readmission risk, mortality, and major adverse cardiovascular events were compared for patients seen by APPs versus physicians only. Patients seen by APPs were more likely to have diabetes mellitus, heart failure, be discharged to a nursing facility, and had more outpatient visits. There was no differences in the factors listed between patients seen by APPs or physicians. Patients seen by APPs were in more need of frequent monitoring and were more likely to have other chronic conditions leading to higher risk of post-MI complications.

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.

Sex and race differences in the utilization and outcomes of coronary artery bypass grafting among Medicare beneficiaries, 1999-2014.
The authors sought to evaluate how the use of coronary artery bypass grafting (CABG) and its outcomes have evolved in different sex and racial subgroups. Using Medicare data, they found that women and black patients had persistently higher CABG mortality than men and white patients, respectively, despite greater declines over the time period. The authors conclude that these findings indicate progress, but further progress is needed.

Trajectories over the first year of long-term care nursing home residence.
This retrospective cohort study examined changes in situation for Medicare fee-for-service beneficiaries newly admitted to long-term nursing homes from July 2012 to December 2013 for the first year after admission. Data was used from the Minimum Data Set and Medicare Provider and Analysis Reviews claims data. Median length of stay in long-term care was 127 days, and for any institution 158 days. At 12 months post admission, 35% had died, 36.9% remained in long-term care, 23.4% were in the community, and 4.7% were in acute care hospitals or other institutions.

Association between Medicare expenditure growth and mortality rates in patients with acute myocardial infarction: a comparison from 1999 through 2014.
This study assessed whether components of growth in Medicare expenditures are associated with mortality rates between January 1, 1999, and June 30, 2014, for beneficiaries hospitalized for acute myocardial infarction. It found that the growth in early percutaneous coronary intervention exhibited a negative association with 180-day case fatality. Spending on cardiac procedures was positively associated with 180-day mortality.

Changes in case-mix and health outcomes of Medicare fee-for-service beneficiaries and managed care enrollees during the years 1992-2011.
This study examined changes in differentials between managed care enrollees (MCEs) and fee-for-service beneficiaries (FFSBs) both in case-mix and health outcomes over time. It found that the case-mix differential between MCEs and FFSBs persisted over time. Both MCEs and FFSBs were as likely to die within 2 years from the Health and Retirement Study interview.

Association between age, substance use, and outcomes in Medicare enrollees with prostate cancer.
The authors analyzed the association between age, substance use, and outcomes in fee-for-service Medicare enrollees with advanced prostate cancer. As they found age-specific results, they recommend an integrated and multidisciplinary approach to screen, refer, and treat substance use in patients with prostate cancer to improve outcomes and reduce costs.

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.

Did Medicare Part D affect national trends in health outcomes or hospitalizations? A time-series analysis.
The researchers examined changes in health outcomes and medical services in the Medicare population after implementation of Medicare Part D. They found that 5 years after implementation, and contrary to previous reports, there was no evidence of Part D's effect on a range of population-level health indicators among Medicare enrollees. Further, there was no clear evidence of gains in medical care efficiencies.

Effectiveness of mesh compared with nonmesh sling surgery in Medicare beneficiaries.
This study assessed the effectiveness of mesh compared to nonmesh slings in the surgical treatment of female incontinence. It found that overall rates of complications were similar for patients undergoing either mesh or nonmesh sling procedures. However, patients undergoing the nonmesh procedure were more likely to require a subsequent intervention for bladder outlet obstruction.
