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.

Early lessons on bundled payment at an academic medical center.
This study was a difference-in-differences study of Medicare fee-for-service patients hospitalized from April 2011 to June 2012 and October 2013 to December 2014 for lower extremity joint arthroplasty, cardiac valve procedures, or spine surgery. It examined total episode costs and costs by service category. It concluded that opportunities for savings under bundled payment may be greater for lower extremity joint arthroplasty than for other conditions.

Association of practice-level social and medical risk with performance in the Medicare physician value-based payment modifier program.
The objective of this cross-sectional observational study was to compare performance in the Physician Value-Based Payment Modifier (PVBM) Program by practice characteristics. The investigators found that during the first year of the Medicare Physician Value-Based Payment Modifier Program, physician practices that served more socially high-risk patients had lower quality and lower costs, and practices that served more medically high-risk patients had lower quality and higher costs.

Regional cost and experience, not size or hospital inclusion, helps predict ACO success.
This study investigated the extent to which organizational characteristics, regional cost of care, or experience in the Medicare Shared Savings Program (MSSP) are associated with the ability to achieve shared savings. It found that experience, as measured by years in the MSSP program, was associated with success and the ability to earn shared savings varied regionally. This variation was strongly associated with differences in regional Medicare fee-for-service per capita costs.

Results of a Medicare bundled payments for care improvement initiative for chronic obstructive pulmonary disease readmissions.
This study evaluated whether a comprehensive chronic obstructive pulmonary disease (COPD) multidisciplinary intervention focusing on inpatient, transitional, and outpatient care as part of an institution's Bundled Payments for Care Improvement (BPCI) participation would reduce 30-day all-cause readmission rates for COPD exacerbations and reduce overall costs. It concluded that a Medicare BPCI intervention did not reduce 30-day all-cause readmission rates or overall costs after hospitalization for acute exacerbation of COPD.

Variation in payment rates under Medicare's Inpatient Prospective Payment System.
The researchers measured variation in payment rates under Medicare's Inpatient Prospective Payment System (IPPS) and identified the main payment adjustments that drive variation. In 2013, Medicare paid for acute inpatient discharges at a rate 31 percent above the IPPS base. For the top 10 percent of discharges, the mean rate was double the IPPS base. Variations were driven by adjustments for medical education and care to low-income populations.

Determinants of success in shared savings programs: an analysis of ACO and market characteristics.
This study examined Accountable Care Organization (ACO) and market factors associated with superior financial performance in Medicare ACO programs. No characteristic of organizational structure was significantly associated with both outcomes of savings per beneficiary and likelihood of achieving shared savings. ACO prior experience with risk-bearing contracts was positively correlated with savings and significantly increased the likelihood of receiving shared savings payments.

Implications of the definition of an episode of care used in the comprehensive care for joint replacement model.
The researchers compared the Comprehensive Care for Joint Replacement (CJR) program's broad definition of an episode of care with a clinically narrow definition of an episode of care. The 90-day episode payments using the broad definition of the CJR model ranged from $17,349 to $29,465 (mean payment, $22,122). Episode payments were slightly lower (mean payment, $21,670) when the Hospital Compare definition was used.

ACOs holding commercial contracts are larger and more efficient than noncommercial ACOs.
The researchers examined differences between commercial accountable care organizations (ACOs) and noncommercial ACOs. They found that among all ACOs, there was low uptake of quality and efficiency activities; commercial ACOs reported more use of disease monitoring tools, patient satisfaction data, and quality improvement methods; and about two-thirds of the ACOs had established processes for distributing any savings accrued. They concluded that ACO delivery systems remain at a nascent stage.

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 Medicare accountable care organization implementation and spending among clinically vulnerable beneficiaries.
The purpose of this cohort study was to examine the effect of Medicare accountable care organization (ACO) contracts on both spending and high-cost institutional utilization for all Medicare beneficiaries and for clinically vulnerable beneficiaries. The main outcomes and measures for this study were total spending per beneficiary-quarter, spending categories, utilization of hospitals and emergency departments, ambulatory care sensitive admissions, and 30-day readmissions. The study found that total spending decreased by $34 per beneficiary-quarter after implementation of ACO contracts across the overall Medicare population and decreased $114 in clinically vulnerable patients. In the overall Medicare cohort, hospitalizations and emergency department visits decreased by 1.3 and 3.0 events per 1000 beneficiaries per quarter, respectively. Hospitalizations and emergency department visits decreased in the clinically vulnerable cohort by 2.9 and 4.1 events per 1000 beneficiaries per quarter, respectively. Variations in total spending related with ACOs did not differ by clinical condition of beneficiaries.
