Association of the Robert Wood Johnson Foundations' social determinants of health and Medicare ocular hospitalizations: a cross sectional data analysis.
The purpose of this paper was to determine whether social determinants of health are associated with ocular hospitalizations. Results showed that, compared to an all-condition hospitalized population, ocular hospitalizations tended to have small, yet statistically significant, associations with health behaviors, socioeconomic, and physical environment factors. Further research is recommended on how these variables affect ocular health relative to all-cause hospitalizations.

Changes in coding of pneumonia and impact on the hospital readmission reduction program.
Researchers evaluated whether changes in diagnosis assignment explain reductions in 30-day readmission for patients with pneumonia following the Hospital Readmission Reduction Program (HRRP). They conducted a retrospective cohort study of Medicare discharges in HRRP-eligible hospitals; outcomes were 30-day readmission rates for pneumonia under both "narrow" and "broad" definitions that included certain diagnoses of sepsis and aspiration pneumonia. They concluded that changes in the coding of inpatient pneumonia admissions do not explain readmission reduction following the HRRP.

The impact of Medicare copayments for skilled nursing facilities on length of stay, outcomes, and costs.
The objective of this study was to investigate the impact of Medicare's skilled nursing facility (SNF) copayment policy, with a large increase in the daily copayment rate on the 20th day of a benefit period, on length of stay, patient outcomes, and costs. The investigators concluded that Medicare's SNF copayment policy was associated with shorter lengths of stay and worse patient outcomes, suggesting the copayment policy had unintended and negative effects on patient outcomes.

Did hospital readmissions fall because per capita admission rates fell?
In this study examining the cause of falling hospital readmission rates, the investigators found that the probability of an admission occurring soon after another was lower when there were fewer admissions per patient. The authors indicate that the reduction in admission rates may explain much of the reduction in readmission rates.

Spending on postacute care after hospitalization in commercial insurance and Medicare around age sixty-five.
Postacute care costs are the primary determinant of episode spending around hospitalization. Yet there is little evidence that greater spending on postacute care improves readmission rates or functional recovery. In a population-based, statewide collaborative of Michigan hospitals, the investigators used regression discontinuity design among propensity-weighted, age-adjusted cohorts to compare postacute care spending between patients with commercial insurance and those with Medicare around age sixty-five. This paper describes the study.

Changes in use of postacute care associated with accountable care organizations in hip fracture, stroke, and pneumonia hospitalized cohorts.
In this study, researchers examined changes in more and less discretionary condition-specific postacute care use associated with Medicare accountable care organization (ACO) implementation. They found that ACOs decreased spending on postacute care by decreasing use of discretionary services. In addition, ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. The authors also observed decreases in spending, readmission days, and mortality among pneumonia patients.

Association of in-hospital resource utilization with post-acute spending in Medicare beneficiaries hospitalized for acute myocardial infarction: a cross-sectional study.
This study compared costs among Medicare fee-for-service beneficiaries aged 65 and over hospitalized with acute myocardial infarction (AMI) from 2010 to 2013 in the Premiere Healthcare Database. The association of in-hospital and post-acute care resource utilization and outcomes was examined. Researchers concluded that greater resource utilization during hospitalization was not associated with meaning differences in costs or mortality rates after hospitalization.

Trends in hospital readmission of Medicare-covered patients with heart failure.
This study sought to compare trends in Medicare risk-adjusted, 30-day readmissions following principal heart failure (HF) hospitalizations and other hospitalizations with HF. The investigators found that patients with HF are often hospitalized for other causes, and these hospitalizations have high readmission rates. Policy changes led to decreases in readmission rates for both principal and secondary HF hospitalizations. Readmission rates in both groups remained high, suggesting that initiatives targeting all hospitalized patients with HF continue to be warranted.

Impact of PAP therapy on hospitalization rates in Medicare beneficiaries with COPD and coexisting OSA.
This retrospective cohort study analyzed data from a national sample of fee-for-service Medicare beneficiaries with a diagnosis of chronic obstructive pulmonary disease (COPD) and coexisting obstructive sleep apnea (OSA) who had begun positive airway pressure (PAP) therapy in 2011. The effect of PAP therapy on emergency room visits and hospitalizations for all-cause and COPD-related conditions was also examined. PAP therapy was more beneficial for older adults, those with higher COPD complexity, and those with three or more comorbidities. PAP therapy in elderly patients with overlap syndrome is associated with a reduction in hospitalization for COPD-related conditions, but not for all-cause hospitalizations or ER visits.

National trends in recurrent AMI hospitalizations 1 year after acute myocardial infarction in Medicare beneficiaries: 1999-2010.
The investigators evaluated changes in the incidence of 1-year recurrent acute myocardial infarction (AMI) hospitalization and mortality. In a national sample of Medicare beneficiaries hospitalized for AMI from 1999 to 2010, they found that hospitalization for recurrent AMI decreased, as did subsequent mortality, albeit to a lesser extent. The risk of recurrent AMI hospitalization declined less in black patients than in whites, increasing observed racial disparities by the end of the study period.
