Medicare Advantage and postdischarge quality: evidence from hospital readmissions.
This study compared relative readmission rates for beneficiaries enrolled in Medicare Advantage (MA) and traditional Medicare (TM). HCUP State Inpatient Databases data for 4 states was used from 2009 and 2014. The outcome compared was the probability of a hospital readmission within 30 days of an index admission. There were significantly lower all-cause readmission rates among MA enrollees relative to those in TM in both 2009 and 2014, but MA enrollment was not associated with an increased reduction in readmission rates relative to TM during that time period.

Weighing the effects of vertical integration versus market concentration on hospital quality.
Provider organizations are increasing in complexity, as hospitals acquire physician practices and physician organizations grow in size. At the same time, hospitals are merging with each other to improve bargaining power with insurers. In this study, the investigators analyzed 29 quality measures reported to the Center for Medicare and Medicaid Services' Hospital Compare database for 2008 to 2015 to test whether vertical integration between hospitals and physicians or increases in hospital market concentration influenced patient outcomes.

Association between specialist compensation and Accountable Care Organization performance.
This study’s objective was to determine whether Medicare Shared Savings Program Accountable Care Organizations (ACOs) using cost reduction measures in specialist compensation demonstrated better performance. National cross-sectional survey data on ACOs from 2013-2015 was linked to public-use data on ACO performance from 2014-2016. Out of 160 ACOs surveys, 26% reported using cost reduction measures to help determine specialist compensation. However, these ACOs did not have savings in the short term.

Association between financial incentives in Medicare's hospital readmissions reduction program and hospital readmission performance.
This study compared the outcome of penalties versus rewards to prevent hospital readmission in Medicare’s Hospital Readmissions Reduction Program (HRRP). This retrospective cohort study used Medicare readmissions data from 2823 US short-term acute care hospitals participating in HRRP. Data from pre-HRRP in 2016 was compared with 2016-2019 3-year follow-up readmission performance classified by tertile of hospitals using baseline marginal incentives for 5 HRRP-targeted conditions: acute myocardial infarction (AMI), heart failure, chronic obstructive pulmonary disease (COPD), pneumonia, and hip and/or knee surgery. Of the 2823 hospitals participating in HRRP from baseline to follow-up, 81% had more than 1 excess readmission for 1 or more applicable condition and 19% did not. Financial incentives ranged from a mean range of $8762 to $58,158 per 1 avoided readmission. Hospitals with greater incentives for readmission avoidance had greater decreases than hospitals with smaller incentives. An additional $5000 in the incentive amount was associated with up to a 26% decrease in readmissions. The findings suggest that incentives work better than penalties to reduce hospital readmissions for those 5 conditions.

Mixed messages to consumers from Medicare: Hospital Compare grades versus value-based payment penalty.
This study examined the discrepancy of ratings with hospitals with low readmission grades for heart failure (HF) and acute myocardial infarction (AMI) on the Hospital Compare website, yet received penalties for excessive readmissions under the hospital Readmissions Reduction Program. A retrospective data analysis was conducted of 2956 hospitals that had publicly reported HF grades on Hospital Compare. Of those, 92% were graded as “no different” than the national rate for HD readmissions, yet included 48.6% that were scored as having excessive HF admissions and 87% received an overall readmission penalty. Of the 120 hospitals graded as “better”, none were scored as having excessive HF readmissions and 50% were penalized. There were similar results for AMI.

HF mortality trends under Medicare readmissions reduction program at penalized and nonpenalized hospitals.
After announcement and implementation of the Medicare Hospital Readmissions Reduction Program (HRRP), 30-day readmissions declined rapidly among seniors with heart failure (HF) while 30-day mortality rose. This raised questions about whether the policy was responsible, because lower HF readmission rates have historically been associated with higher mortality. In this study, the investigators compared trends in heart failure (HF) mortality at penalized and nonpenalized hospitals nationally.

Quality of care improves for patients with diabetes in Medicare shared savings accountable care organizations: organizational characteristics associated with performance.
This study analyzed secondary data retrospectively to examine Medicare Shared Savings Program (MSSP) Accountable Care Organizations’ performance on diabetes metrics in the first 2 years of ACO contracts in order to determine how ACO organizational characteristics - such as composition, staffing, care management, and experiences with health reform - were associated with quality of care delivered to patients with diabetes.

Performance in the Medicare Shared Savings Program by accountable care organizations disproportionately serving dual and disabled populations.
The purpose of this study was to examine performance by accountable care organizations (ACOs) in the top quintile of their proportion of beneficiaries who were dually enrolled in Medicare and Medicaid (high-dual), and the top quintile of disabled beneficiaries (high-disabled). Measures used were quality scores, savings per beneficiary, whether or not the ACO shared savings and the amount of shared savings. The researchers found that high-dual and high-disabled ACOs had similar or higher spending than other ACOs at baseline, but achieved greater savings and were equally or more likely to earn shared savings; alternative payment models can have positive financial outcomes for providers serving vulnerable populations.

Associations of CAHPS composites with global ratings of the doctor vary by Medicare beneficiaries' health status.
This study examines whether the association of care coordination with global ratings of one's personal doctor varies by number of chronic conditions and self-rated health. Results were consistent with the hypothesis that patients in worse health weigh care coordination more heavily in global physician assessments than patients in better health. Emphasis on improving care coordination, especially for patients in poorer health, may improve patients' overall assessments of their providers.

Financial incentives and physician practice participation in Medicare's value-based reforms.
The purpose of this study was to evaluate whether greater experience and success with performance incentives among physician practices are related to increased participation in Medicare's voluntary value-based payment reforms. The authors concluded that Medicare must complement financial incentives with additional efforts to address the needs of practices with less experience with such incentives to promote value-based payment on a broader scale.

National trends in open surgical, endovascular, and branched-fenestrated endovascular aortic aneurysm repair in Medicare patients.
Open repair effectively prevents rupture for patients with abdominal aortic aneurysm (AAA) and is commonly studied as a metric reflecting hospital and surgeon expertise in cardiovascular care. However, given recent advances in endovascular aneurysm repair (EVAR), such as branched-fenestrated EVAR, it is unknown how commonly open surgical repair is still used in everyday practice. This study analyzed trends in open AAA repair, EVAR, and branched-fenestrated EVAR for AAA in Medicare beneficiaries from 2003 to 2013.

Exploring the evidence base behind quality measures.
This study examined the strength of evidence behind quality measures used in Medicare’s 2016 Shared Savings Program. These measures apply to more than 430 accountable care organizations (ACOs). Differences existed in the grading systems used and the evidentiary strength. Based on average ACO performance, performance appeared to be lower in the moderate evidence category (overall average, 61 percent) compared to the high evidence category (overall average, 77 percent).

Association between 5-Star nursing home report card ratings and potentially preventable hospitalizations.
The goal of this study was to test whether the improvements in nursing homes’ 5-star ratings were correlated with reductions in rates of hospitalization; the researchers’ hypothesis was that increased attention to ratings motivated nursing homes to make changes to improve ratings but did not affect hospitalization rate, resulting in a weakened association between ratings and hospitalizations. 2007-2010 Medicare hospital claims and nursing home clinical assessment data were used to compare the correlation between nursing homes’ ratings and hospitalization rates. Correlation weakened slightly after the ratings became publicly available. The researchers conclude that improvements in nursing home ratings after the release of Medicare's 5-star rating system were not accompanied by improvements in a broader measure of outcomes for post-acute care patients and, although this dissociation may be due to additional factors, the 5-star ratings became less meaningful as an indicator of nursing home quality for these patients.

Mortality rate estimation and standardization for public reporting: Medicare’s Hospital Compare.
The authors calibrated Bayesian recommendation systems by checking, out of sample, whether predictions aggregate to give correct general advice derived from another sample. Their process leads to substantial revisions in the Hospital Compare model for acute myocardial infarction mortality. They found that indirect standardization, as currently used by Hospital Compare, fails to adequately control for differences in patient risk factors and systematically underestimates mortality rates at the low volume hospitals. They proposed direct standardization instead.

Medicare's new bundled payment for joint replacement may penalize hospitals that treat medically complex patients.
Using Medicare claims for patients in Michigan who underwent lower extremity joint replacement in the period 2011-13, the researchers applied payment methods analogous to those CMS intends to use in determining annual bonuses or penalties (reconciliation payments) to hospitals. Their findings suggest that CMS should include risk adjustment in the Comprehensive Care for Joint Replacement program and in future bundled payment programs.

Association between hospital performance on patient safety and 30-day mortality and unplanned readmission for Medicare fee-for-service patients with acute myocardial infarction.
The researchers studied the relationship between hospital performance on adverse event rates and hospital performance on 30-day mortality and unplanned readmission rates for Medicare fee-for-service patients hospitalized for acute myocardial infarction (AMI). They found that for Medicare fee-for-service patients discharged with AMI, hospitals with poorer patient safety performance were also more likely to have poorer performance on 30-day all-cause mortality and on unplanned readmissions.

The role of medical group practice administrators in the adoption and implementation of Medicare's physician quality reporting system.
The purpose of this study was to gain insights into the role these administrators play in quality assurance programs. It found that administrators conducted due diligence on Medicare's physician quality reporting system, influenced how the issue was presented to physicians for adoption, and managed implementation thereafter. Administrators' recommendations were heavily influenced by practice characteristics, financial incentives, and practice commitments to early adoption of quality improvement innovations.

Adding a spending metric to Medicare's value-based purchasing program rewarded low-quality hospitals.
In fiscal year 2015 the Centers for Medicare and Medicaid Services expanded its Hospital Value-Based Purchasing program by rewarding or penalizing hospitals for their performance on both spending and quality. Using data from 2,679 US hospitals that participated in the program in fiscal years 2014 and 2015, researchers found that the new emphasis on spending rewarded not only low-spending hospitals but some low-quality hospitals as well.

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.
