Assessment of hospital readmissions from the emergency department after implementation of Medicare's hospital readmissions reduction program.
The purpose of this study was to examine whether the Medicare Hospital Readmissions Reduction Program (HRRP) was associated with changes in the probability of readmission at emergency department (ED) visits after hospital discharge (ED revisits) overall and depending on whether admission is typically indicated for the patient's condition at the ED revisit. Using hospital and ED discharge data from California, Florida, and New York, findings suggested that implementation of the HRRP was associated with a lower likelihood of readmission for recently discharged patients presenting to the ED, specifically for congestive heart failure. These findings highlighted the critical role of the ED in readmission reduction under the HRRP and suggested that patient outcomes after HRRP implementation merit further study.

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.

Racial differences in discharge location after a traumatic brain injury among older adults.
The purpose of this retrospective cohort study was to determine if there were racial differences in discharge location among older adults treated for traumatic brain injury (TBI) at a level 1 trauma center. The authors concluded that in this group of Medicare-eligible older adults, blacks were more likely to be discharged to inpatient rehabilitation compared to whites.

Medicare's bundled payment model did not change skilled nursing facility discharge patterns.
The purpose of this study was to evaluate whether participation in Medicare's voluntary Bundled Payments for Care Improvement (BPCI) model was associated with changes in discharge referral patterns to skilled nursing facilities (SNFs), specifically number of SNF partners and discharge concentration. The investigators concluded that hospital participation in BPCI was not associated with changes in the number of SNF partners or in discharge concentration relative to non-BPCI hospitals.

Do hospitals participating in accountable care organizations discharge patients to higher quality nursing homes?
This study examined whether hospitals participating in Medicare's Shared Saving Program increased use of highly rated skilled nursing facilities (SNFs) or decreased the use of low-rated SNFs after initiation of accountable care organization (ACO) contracts, compared with non-ACO hospitals. The findings indicate that, after joining an ACO, the percentage of hospital discharges going to a high-quality SNF increased slightly; the probability of discharge from ACO-participating hospitals to low-quality SNFs did not change significantly in comparison with non-ACO hospitals.

Thirty-day postdischarge mortality among black and white patients 65 years and older in the Medicare Hospital Readmissions Reduction Program.
The goal of this cohort study was to determine whether short-term mortality rates increased among black and white adults 65 years and older after initiation of the Medicare Hospital Readmissions Reduction Program (HRRP) and whether trends differed by race. Using an interrupted time-series analysis, the researchers found that short-term post-discharge mortality did not appear to increase for black patients under the HRRP, suggesting that certain value-based payment policies can be implemented without harming black populations. However, mortality seemed to increase for white patients with heart failure; this situation warrants investigation.

Readmission patterns over 90-day episodes of care among Medicare fee-for-service beneficiaries discharged to post-acute care.
This retrospective cohort study’s objective was to examine readmission patterns over 90-day episodes of care in patients discharged from hospitals to skilled nursing facilities (SNFs). Data was used from a national cohort of Medicare fee-for-service beneficiaries discharged from SNF care from July 2013 to July 2014. The cohort studied were adults 65 years and older who were hospitalized for stroke, joint replacement, or hip fracture, and had survived 90 days post-discharge. Patients with hemorrhagic stroke were more likely than those with ischemic stroke to be rehospitalized over the first 30 days after discharge. For patients receiving nonelective joint replacements, readmissions increased from the 30 to 90-day period post-acute discharge.

Changes in health care costs and mortality associated with transitional care management services after a discharge among Medicare beneficiaries.
Medicare adopted transitional care management (TCM) payment codes in 2013 to encourage clinicians to furnish TCM services after beneficiaries were discharged to the community from medical facilities. The purpose of this study was to investigate whether the receipt of TCM services was associated with the subsequent health care costs and mortality of the beneficiaries in the month after the service was provided. The study concluded that despite the apparent benefits of TCM services for Medicare beneficiaries, the use of this service remains low.

Functional status is associated with 30-day potentially preventable hospital readmissions after inpatient rehabilitation among aged Medicare fee-for-service beneficiaries.
This study has two purposes: Determine the association between functional status of patients at discharge following inpatient rehabilitation and their potentially preventable readmission; Examine conditions that result in potentially preventable readmissions. The study examined inpatient rehabilitation facilities that submitted claims to Medicare, and concluded that functional status is associated with readmission and this may help to identify at-risk patients.

Impact of postdischarge follow-up care on Medicare expenditures: does rural make a difference?
Reducing postdischarge Medicare expenditures is a key focus for hospitals. Early follow-up care is an important piece of this focus, but it is unclear whether there are rural-urban differences in the impact of follow-up care on Medicare expenditures. To assess this difference, the study authors used Medicare Current Beneficiary Survey, Cost and Use Files, 2000-2010 to conduct a retrospective analysis of 30-day postdischarge Medicare expenditures using two-stage residual inclusion with a quantile regression, where the receipt of 7-day follow-up care was the main independent variable.

Functional status is associated with 30-day potentially preventable readmissions following skilled nursing facility discharge among Medicare beneficiaries.
This retrospective cohort study’s objective was to determine the association between patients’ functional status at discharge from skilled nursing facility (SNF) care and 30-day potentially preventable readmissions. Data was used from a national cohort of Medicare fee-for-service beneficiaries discharged from SNF care from July 2013 to July 2014. The average age was 81.4 years, 67% were women, and 86.3% non-Hispanic white. Functional data used from the Minimum Data Set was self-care, mobility, and cognition domains. The overall rate of 30-day potentially preventable readmissions was 5.7%. The 5 most common conditions for readmissions were congestive heart failure, septicemia, urinary tract infection, bacterial pneumonia, and renal failure. Mobility was the most dependent category followed by self-care and cognition.

New institutionalization in long-term care after hospital discharge to skilled nursing facility.
Approximately half of individuals newly admitted to long-term care (LTC) nursing homes (NHs) experienced a prior hospitalization followed by discharge to a skilled nursing facility (SNF). The objective of this study was to examine characteristics associated with new institutionalizations of older adults on this care trajectory. Associations between risk factors and new LTC institutionalizations varied according to race and ethnicity, age, and level of cognitive function.

Association of postdischarge spending and performance on new episode-based spending measure.
The Centers for Medicare and Medicaid Services recently added the Medicare Spending per Beneficiary (MSPB) metric to its Hospital Value-Based Purchasing (HVBP) program. The researchers evaluated whether hospital performance was driven by spending before, during, or after hospitalization. They found that compared with low-cost hospitals, high-cost hospitals had significantly higher preadmission and index admission spending, but the largest differences were in postdischarge spending.

Changes in discharge location and readmission rates under Medicare bundled payment.
To control costs, NYU Langone Medical Center attempted to shift referrals from facility-based to home-based postacute care. In the context of this shift in referrals, the researchers examined the change in hospital readmission rates. Their findings suggest that institutions may be able to shift some patients from facility-based to home-based postacute care without adversely affecting hospital readmission rates or the length of hospital stay.

Variation in readmission rates by emergency departments and emergency department providers caring for patients after discharge.
This study of Texas acute-care hospitals and ED facilities has found that the risk of readmission varies by ED provider caring for patients after discharge. A large part of this variation is explained by the ED facility in which the ED providers practice. Thus, ED provider practices patterns and ED facility systems of care may be a target for interventions to reduce readmissions.
