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.

Getting what we pay for: how do risk-based payments to Medicare Advantage plans compare with alternative measures of beneficiary health risk?
The purpose of this study was to estimate the relative health risk of Medicare Advantage (MA) beneficiaries compared to those in Traditional Medicare (TM). The investigators indicate that their findings add to a growing body of evidence suggesting MA receives favorable, or, at worst, neutral selection. They assert that if MA beneficiaries are no healthier and no sicker than similar beneficiaries in TM, then payments to MA plans exceed what is warranted based on their health status.

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.

Effect of site-neutral payment policy on long-term acute care hospital use.
The purpose of this study was to assess the projected effect of the Centers for Medicare and Medicaid Services new site-neutral payment policy, which aims to decrease unnecessary long-term acute care hospital (LTACH) admissions by reducing reimbursements for less-ill individuals by 2020. The investigators concluded that the site-neutral payment policy may limit LTACH access in existing LTAC-scarce markets, with potential adverse implications for recovery of hospitalized older adults.

Payment innovations to improve diagnostic accuracy and reduce diagnostic error.
Researchers examined ways that payment innovations could be used to improve diagnostic accuracy and reduce diagnostic error among Medicare patients. They recommended three different approaches: 1) coding changes in the Medicare Physician Fee schedule; new Alternative Payment Models (APMs) that could improve accuracy in challenging cases and even provide second or third opinions; and 3) have a method that accurate diagnoses would trigger APM payments and establish payment amounts.

Medicare payment penalties and safety net hospital profitability: minimal impact on these vulnerable hospitals.
The purpose of this study was to examine relationships between penalties assessed by Medicare's Hospital Readmission Reduction Program and Value-Based Purchasing Program and hospital financial condition. The investigators conducted bivariate and multivariate analysis of pooled cross-sectional data and found that safety net hospitals appear to rely on nonpatient care revenues to offset higher penalties for the years studied. They assert that while reassuring, these funding streams are volatile and may not be able to compensate for cumulative losses over time.

National trends in active surveillance for prostate cancer: validation of medicare claims-based algorithms.
This study analyzed the use of active surveillance of low-risk prostate cancer among a wide variety of health care practices. Researchers identified men with prostate cancer from 2012-2014 using a 100% sample of Michigan Medicare data and linked them with the Michigan Urologic Surgery Improvement Collaborative (MUSIC) registry. They analyzed the performance of 8 claims-based algorithms that were used and selected 3 of them to apply to a 20% national Medicare sample. The 3 algorithms were determined to be either the most sensitive, the most specific, and a balanced algorithm incorporating age and comorbidity. They found that use of surveillance for men increased from 2007 to 2014 but there was a large decrease in the rate of prostate cancer diagnosis. The rate of active surveillance either increased or remained stable depending on the algorithm used.

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.

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.

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.

The effect of Medicare accountable care organizations on early and late payments for cardiovascular disease episodes.
In this study, the investigators examined the association between Medicare accountable care organization (ACO) implementation and episode spending for 2 different cardiovascular conditions. The investigators found that for beneficiaries with acute myocardial infarction or congestive heart failure, admission to ACO participating hospitals was not associated with changes in early episode spending, but it was associated with significant savings during the late episode. ACO effects on late episode spending may complement other value-based payment reforms that target the early episode.

Participation in a voluntary bundled payment program by organizations providing care after an acute hospitalization
This research letter addresses spending on post–acute care (PAC), or care provided after a stay in an acute care hospital. PAC is the largest driver of variation in total per capita Medicare spending. To address this, Medicare has targeted PAC spending in payment reforms including voluntary bundled payment programs. This letter discusses participation in these voluntary payment programs.

Early effects of Medicare's Bundled Payment For Care Improvement program for lumbar fusion.
The purpose of this study was to describe the early effects of Bundled Payment for Care Improvement (BPCI) program participation for lumbar fusion on 90-day reimbursement, procedure volume, reoperation, and readmission. The investigators included 89,605 beneficiaries undergoing lumbar fusion, finding that the mean age was 73.4 years, with 59% women, 92% White, and 22% with a Charlson Comorbidity Index of 2 or more. Participant hospitals had greater procedure volume, bed size, and total discharges. Relative to nonparticipants, risk-bearing hospitals had a slightly increased fusion procedure volume from 2012 to 2013, did not reduce 90-day episode of care costs, increased 90-day readmission rate, and increased repeat surgery rates.

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).

Offsetting patient-centered medical homes investment costs through per-member-per-month or Medicare merit-based incentive payment system incentive payments.
The purpose of this study was to examine potential offsets through commercial payer per-member-per-month (PMPM) payments and the Medicare Merit-based Incentive Payment System (MIPS). The researchers found that with PMPM, breaking even required that 2.4% to 6.4% of commercially insured patients per physician to be covered; with MIPS incentive payments, they would exceed PCMH costs by 2022.

Payer type and low-value care: comparing Choosing Wisely services across commercial and Medicare populations.
This study compared low-value health service use among commercially insured and Medicare populations and explored the influence of payer type on the provision of low-value care. In measuring use of seven Choosing Wisely-identified low-value services, it concluded that low-value care appears driven by factors unrelated to payer type or anticipated reimbursement.

Can amputation save the hospital? The impact of the Medicare Rural Flexibility Program on demand and welfare.
This paper sought to understand the impact of the Medicare Rural Hospital Flexibility (Flex) Program on hospital choice and consumer welfare for rural residents. The Flex Program created a new class of hospital, the Critical Access Hospital (CAH), which received more generous Medicare reimbursements in return for limits on capacity and length of stay. The investigators found that conversion to CAH status resulted in a 4.7 percent drop in inpatient admissions to participating hospitals, almost all of which was driven by factors other than capacity constraints.

Consequences of the 340B drug pricing program.
Researchers used Medicare claims and a regression-discontinuity design, taking advantage of the threshold for program eligibility among general acute care hospitals to isolate the effects of the 340B Drug Pricing Program on hospital-physician consolidation and on the outpatient administration of parenteral drugs. They concluded that the Program has been associated with hospital-physician consolidation in hematology-oncology and with more hospital-based administration of parenteral drugs in hematology-oncology and ophthalmology.

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.

Complying with the Emergency Medical Treatment and Labor Act (EMTALA): challenges and solutions.
EMTALA, which requires Medicare-participating hospitals to provide emergency care to patients regardless of their ability to pay, plays an important role in protecting the uninsured. Yet many hospitals do not comply. This study examines the reasons for noncompliance and proposes solutions. Respondents identified 5 main causes of noncompliance as well as suggesting methods to improve compliance.

Measuring coding intensity in the Medicare Advantage program.
Each year from 2004-2013, the average Medicare Advantage risk score increased faster than the average fee-for-service score. The intensity of coding varies widely by contract. The authors suggested that with the continuous relative increase in the average Medicare Advantage risk score, further policy changes will likely be necessary.
