Performance in the Medicare Shared Savings Program after accounting for nonrandom exit: an instrumental variable analysis.
The purpose of this study was to evaluate the effect of the Medicare Shared Savings Program (MSSP) on spending and quality while accounting for clinicians' nonrandom exit. MSSP ACO participants were compared with control beneficiaries using adjusted longitudinal models that accounted for secular trends, market factors, and beneficiary characteristics. Results showed that, after adjustment for clinicians' nonrandom exit, the MSSP was not associated with improvements in spending or quality. Selection effects, including exit of high-cost clinicians, may drive estimates of savings in the MSSP.

Reference pricing: the case of screening colonoscopies.
In this study, the investigators studied the introduction of reference pricing to the California Public Employees' Retirement System. The investigators found a 10 percentage point increase in the share of patients using an ambulatory surgery center (ASC), leading to a $2300 to $1700 reduction in prices paid for patients who switched to ASCs. They indicated that their results suggested the use of ASCs had a causal effect on prices paid and had no negative effect on patient health outcomes.

Medicaid expansion and health plan quality in Medicaid managed care.
The purpose of the study was to assess the effect of the 2014 Medicaid expansion on Medicaid managed care plan quality. The study concluded that Medicaid expansion increased enrollment in managed care plans, but it did not result in erosion of quality.

The new era of precision population health: insights for the All of Us Research Program and beyond.
This paper addresses the new era of precision population health. Although precision medicine has made advances in individualized patient treatments, the authors assert that there needs to be continued attention on tailored population health and prevention strategies. They provide specific recommendations from the All of Us Research Program and the Precision Public Health Summit as examples for moving this field forward.

Projected effectiveness and added value of HIV vaccination campaigns in South Africa: a modeling study.
Sci Rep 2018 Apr 17;8(1):6066. doi: 10.1038/s41598-018-24268-4.
In this paper, the authors estimated the potential epidemiological and economic impact of HIV vaccine campaigns compared to continuous vaccination, assuming that vaccine efficacy was transient and dependent on immune response. The investigators concluded that results suggested a partially effective HIV vaccine would have substantial impact on the HIV epidemic in South Africa and offer good value if priced less than $105 for a five-dose series. They suggested that vaccination campaigns every two years may offer greater value for money than continuous vaccination reaching the same coverage level.

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.

Impact of a value-based formulary on medication utilization, health services utilization, and expenditures.
The objective of the study was to determine the impact of the value-based formulary (VBF). It found that cost-sharing informed by cost-effectiveness analysis reduced overall medication expenditures without negatively impacting medication utilization, health services utilization, or nonmedication expenditures.

Role of health services research in producing high-value rehabilitation care.
The overall purpose of this article is to present a framework to help clinicians, researchers, educators, and policy makers better understand the role of health services research in developing and evaluating evidence on value in rehabilitation. The authors believe that rehabilitation professionals have a great opportunity to increase their engagement in describing, evaluating, delivering, and disseminating high-value care, but there are several barriers they need to consider to be most successful.

Apple pickers or federal judges: strong versus weak incentives in physician payment.
The authors provide an introduction for five papers commissioned by AHRQ focusing on incentives for physicians that are featured in this special issue of Health Services Research. These papers concentrate on suggesting a conceptual framework for the use of financial incentives in health care, key implications of the evidence to date on pay for performance and public reporting in health care and several related topics.

Higher incentive payments in Medicare Advantage's pay-for-performance program did not improve quality but did increase plan offerings.
The researchers evaluated the effects of the size of financial bonuses on quality of care and the number of plan offerings in the Medicare Advantage Quality Bonus Payment Demonstration. They concluded that at great expense to Medicare, double bonuses in the Medicare Advantage Quality Bonus Payment Demonstration were not associated with improved quality but were associated with more plan offerings.

Policy-oriented research on improved physician incentives for higher value health care.
Policy makers (both public and private) are seeking ways to improve the value delivered within our health care system. To inform such policy changes, this paper identifies areas in which little is known about the effects of specific incentives (FFS, salary, etc.) on the two components of value: resource use and quality. Specific suggestions are offered focusing on fundamental "building block" studies.

Pursuit of value in connected healthcare.
The authors highlighted differences in care models to mitigate controversy and to distinguish capacities of these different models. They concluded that the pursuit of value in connected care is fundamentally the same as with in-person care.

Why we should not be indifferent to specification choices for difference-in-differences.
The purpose of this study was to evaluate the effects of specification choices on the accuracy of estimates in difference-in-differences models. They found that performance of alternative specifications varied dramatically when the probability of treatment was correlated with pre-intervention levels or trends. In these cases, propensity score matching resulted in much more accurate point estimates.
